Sennheiser
Sennheiser HD 800 S Open-Back Headphones – Black
56 mm Ring Radiator drivers
The Sennheiser HD 800 S is a wired, open-back over-ear headphone for home listening and critical evaluation. Its 56 mm Ring Radiator dynamic transducers sit in angled earcups, with absorber technology designed to reduce unwanted resonances. The open construction lets room sound in and headphone sound out, making a quiet listening space more suitable than a busy commute. Sennheiser specifies 300-ohm impedance, so pair the headphones with an output capable of driving a high-impedance load at your preferred level. Detachable cable connections support the manufacturer-listed 6.35 mm single-ended and 4.4 mm balanced arrangements; balanced use needs a compatible output. No particular amplifier is included or mandatory by name. This listing is the Black HD 800 S alone, not the HDV 820 bundle or a closed-back HD 820.

Audeze
Audeze LCD-X Open-Back Planar Headphones – Leather-Free Black
106 mm planar-magnetic drivers
The Audeze LCD-X is a wired, open-back planar-magnetic headphone for critical listening and studio work. Its 106 mm transducers use the manufacturer’s Fazor phase-management technology and an ultra-thin diaphragm. Audeze publishes 20-ohm impedance, but a suitable headphone output is still important: low impedance alone does not establish that every phone or adapter will drive it comfortably. This listing follows the donor’s Leather-Free Black configuration, with no claim that 2024 is a separate official model generation. The open design does not isolate against room noise and allows sound to escape. Detachable cable connections support practical studio use, while the exact regional package must govern supplied accessories. Current manufacturer cable-package changes are not automatically assigned to the donor’s older retail listing. No interface, amplifier or desk equipment is included.

Focal
Focal Bathys MG Wireless Over-Ear Headphones – Chestnut
40 mm magnesium M-shaped drivers
The Focal Bathys MG in Chestnut is a pair of closed-back, over-ear headphones combining wireless listening with active noise cancellation. Its 40 mm magnesium M-shaped drivers are made in Focal’s French workshops, while Bluetooth 5.2 provides the wireless connection. Silent and Soft modes let you choose the amount of noise reduction, and Transparent mode helps you hear your surroundings without removing the headphones. For compatible wired sources, USB-DAC operation supports audio up to 24-bit/192 kHz; this resolution does not apply to Bluetooth playback. SBC, AAC, aptX and aptX Adaptive are supported, although the codec available depends on the transmitting device. Battery life is rated at 30 hours using Bluetooth and noise cancelling. A carrying case, USB-C cable and 3.5 mm audio cable are supplied, while the Focal & Naim app provides further sound adjustment.

Sennheiser
Sennheiser IE 900 Wired In-Ear Earphones – Aluminium
7 mm TrueResponse drivers
The Sennheiser IE 900 uses a single 7 mm TrueResponse dynamic transducer in each precision-milled aluminium earpiece. Its X3R acoustic system combines three resonator chambers with an acoustic vortex to control resonances without relying on multiple drivers. The earphones are wired and use Fidelity+ MMCX cable connections with adjustable ear hooks. Manufacturer-listed cable options include 3.5 mm single-ended and 2.5 mm and 4.4 mm balanced plugs, so the chosen cable must match the headphone output on your source. Balanced wiring is optional rather than a guaranteed upgrade for every system. The 18-ohm impedance is not a reason to claim a particular amplifier is mandatory. Appropriate ear tips provide passive isolation; these earphones do not offer Bluetooth or active noise cancellation. This listing is the Aluminium IE 900, not a complete music-player system.

Shure
Shure SE846 Gen 2 Wired Earphones — Clear
Clear SE846G2CL-EFS, second-generation wired package
The Shure SE846 Gen 2 in Clear is a wired in-ear earphone package identified by manufacturer code SE846G2CL-EFS. Four custom drivers work in a three-way system with dedicated low, mid and high-frequency reproduction. A low-pass filter manages the low-frequency section, while removable nozzle inserts provide four selectable sound signatures: extended, balanced, warm and bright. The extended insert is the default second-generation configuration. Noise reduction is passive: correctly fitted sleeves seal against the ear to block outside sound, rather than using electronic active noise cancellation. Shure quotes up to 37dB isolation, with the result dependent on fit. A detachable cable connects through MMCX sockets and terminates in a 3.5mm plug. The over-ear cable design keeps the cable routed around the ear during listening or monitoring. The wired EFS package includes sleeves, a quarter-inch adapter, a hard carrying case and the tools/inserts for adjustment. Bluetooth adapters and wireless monitoring transmitters are separate; this listing is not a wireless bundle. No waterproof or active-noise-cancelling claim is made.

DALI
DALI IO-12 Dark Chocolate Wireless Headphones
Closed-back wireless listening with ANC
The DALI IO-12 is a closed-back wireless headphone in the Dark Chocolate finish, combining active noise cancellation with wired connection options. Its 50 mm paper-fibre cone drivers use DALI’s SMC-based magnet system, a feature that distinguishes this model from the IO-8. Bluetooth 5.2 provides wireless playback from compatible devices, while USB-C and a 3.5 mm analogue input offer alternatives for suitable sources. The manufacturer quotes up to 35 hours of battery playback, with actual duration depending on use. The specified 25-ohm impedance applies to passive operation, not to the wireless connection. Selectable Hi-Fi and Bass modes let the listener choose between the available sound settings. This listing supplies one IO-12 headphone set, not the computers or home-audio equipment visible in lifestyle photography. Clean product angles are retained; exploded diagrams and room scenes are excluded.

FiiO
FiiO EA13 Stereo Valve Amplifier — Black
Class A push-pull design with two PCF80 and four EL34 valves
The FiiO EA13 is a black stereo valve amplifier built around Class A push-pull amplification. Its preamp section uses two PCF80 valves, with four EL34 valves in the power stage. Four selectable RCA line inputs allow connection of analogue source components; a turntable requiring phono equalisation needs a separate suitable phono stage. Dedicated speaker connections provide 4-ohm and 8-ohm options, while a 6.35 mm single-ended headphone socket supports personal listening. FiiO specifies at least 18 W per channel into either 4 or 8 ohms at THD+N below 1%; its higher 28 W per-channel rating uses the less stringent below-5% condition and should not be treated as the same measurement. Mechanical VU meters and rotary controls provide input selection and volume adjustment. The chassis measures approximately 430 by 339 by 145 mm and weighs about 17.7 kg. A 3.5 mm trigger input supports system integration. This model has analogue line inputs rather than a built-in Bluetooth receiver or digital DAC; speakers and source equipment are not included.

Meze Audio
Meze Audio 109 PRO Open-Back Headphones – Dark Walnut
50 mm dynamic driver
The Meze Audio 109 PRO combines an open-back design with Black Walnut Wood earcups and a 50 mm dynamic driver. The construction uses walnut, cast zinc, manganese steel and vegan-leather elements, with velour ear pads and a self-adjusting headband for over-ear listening. Meze publishes a 40-ohm impedance and a 5 Hz to 30 kHz frequency range. Dual 3.5 mm TS sockets connect the detachable cable to the two earcups, rather than providing a wireless connection. The open cups let room sound in and headphone sound out, making home listening in a quiet environment more appropriate than noisy commuting. This listing is the standard Dark Walnut 109 PRO, not the carved Primal edition. It does not include a music player or amplifier, and package cable claims are not borrowed from a different edition.

Bowers & Wilkins
Bowers & Wilkins Px8 S2 Wireless Over-Ear Headphones – Onyx Black
40 mm carbon drivers
The Bowers & Wilkins Px8 S2 in Onyx Black combines an over-ear design with active noise cancellation and a choice of wireless or wired connections. Its two 40 mm carbon drivers work with dedicated digital processing and amplification. Bluetooth 5.3 supports codecs including aptX Lossless, aptX Adaptive, AAC and SBC, but the format used depends on the connected source and connection conditions. The Bowers & Wilkins Music app offers a five-band equaliser, allowing you to adjust the presentation to your preferences. An eight-microphone system supports noise cancellation and voice calls. Battery life is rated at up to 30 hours, with actual endurance dependent on the features in use; a 15-minute charge provides up to seven hours of playback. The package includes a carrying case and both USB-C to USB-C and USB-C to 3.5 mm cables.

Focal
Focal Bathys Wireless Over-Ear Headphones – Black
40 mm aluminium/magnesium M-shaped drivers
The Focal Bathys in Deep Black is a pair of closed-back, over-ear headphones combining wireless listening with active noise cancellation. Its 40 mm aluminium/magnesium M-shaped drivers are made in France, with Bluetooth 5.1 handling wireless playback. Silent and Soft modes let you choose the amount of noise reduction, and Transparent mode helps you hear your surroundings without removing the headphones. For compatible wired sources, USB-DAC operation supports audio up to 24-bit/192 kHz; this resolution does not apply to Bluetooth playback. SBC, AAC, aptX and aptX Adaptive are supported, although the codec available depends on the transmitting device. Battery life is rated at 30 hours using Bluetooth and noise cancelling. A carrying case, USB-C cable and 3.5 mm audio cable are supplied, while the Focal & Naim app provides further sound adjustment.

Sennheiser
Sennheiser IE 600 Wired In-Ear Earphones
7 mm TrueResponse dynamic drivers
The Sennheiser IE 600 is a wired in-ear earphone built around a single 7 mm TrueResponse dynamic transducer in each earpiece. Its compact ZR01 amorphous-metal housings incorporate dual-chamber absorbers to manage acoustic resonances. Detachable cables connect through the recessed Fidelity+ MMCX sockets, with 3.5 mm single-ended and 4.4 mm balanced cable options supplied. Adjustable ear hooks help position the earpieces, while suitable ear tips provide passive isolation rather than electronic active noise cancellation. The 18-ohm design needs a compatible headphone output; a balanced cable requires a matching balanced socket and is not a promise of better sound from every source. This listing contains the IE 600 earphones, not a player or amplifier. There is no Bluetooth connection, rechargeable battery or wireless charging feature.

DALI
DALI IO-8 Iron Black Wireless Headphones
Closed-back over-ear design with ANC
The DALI IO-8 combines a closed-back over-ear design with wireless listening and active noise cancellation. This listing is the Iron Black finish, identified by the donor as Black. Custom 50 mm drivers use paper-fibre cones, while selectable Hi-Fi and Bass sound modes provide two listening approaches. Bluetooth 5.2 supports compatible wireless sources, and the manufacturer also lists 3.5 mm analogue and USB-C audio inputs. The stated battery playback time is up to 35 hours, rather than a guaranteed duration for every volume, connection or listening condition. Passive-mode impedance is specified as 25 ohms; that figure should not be treated as a Bluetooth performance rating. Compatible sources, recordings and connection settings determine available audio formats. The prepared gallery contains only clean views of the exact dark finish, with the review badge and photographs of people removed.

beyerdynamic
beyerdynamic DT 1990 PRO MKII Studio Headphones
Open-back wired studio design
The beyerdynamic DT 1990 PRO MKII is a wired, open-back over-ear studio headphone designed for mixing, mastering and editing. Its TESLA.45 dynamic driver is specified at 30 ohms: TESLA.45 is the technology name, not a 45-ohm impedance rating. The MKII must also be distinguished from the older 250-ohm generation. The open construction allows sound to escape and room noise to enter, so it is more suitable for a quiet studio than isolated live monitoring. A detachable single-sided mini-XLR cable connection supports replacement and transport, and the manufacturer lists 3 m straight and 5 m coiled cables. The padded headband incorporates a fontanelle recess intended to reduce pressure at the top of the head. This listing contains the MKII headphones rather than a microphone, audio interface or recording package. Bluetooth and battery-powered operation are not part of the design.

beyerdynamic
beyerdynamic DT 1770 PRO MKII Studio Headphones
Closed-back wired studio design
The beyerdynamic DT 1770 PRO MKII is a wired, closed-back over-ear studio headphone designed for recording, monitoring and editing. Its TESLA.45 dynamic driver is specified at 30 ohms: TESLA.45 is the technology name, not a 45-ohm impedance rating. The MKII must also be distinguished from the older 250-ohm generation. The closed construction provides passive isolation from the room; it is not electronic active noise cancellation. A detachable single-sided mini-XLR cable connection supports replacement and transport, and the manufacturer lists 3 m straight and 5 m coiled cables. The padded headband incorporates a fontanelle recess intended to reduce pressure at the top of the head. This listing contains the MKII headphones rather than a microphone, audio interface or recording package. Bluetooth and battery-powered operation are not part of the design.

Focal
Focal Hadenys Brown Open-Back Headphones
Open-back wired headphone
The Focal Hadenys is a brown, passive wired headphone built for listening in a quieter home environment. Its open-back construction allows sound to pass through the earcups, so it is not intended to isolate the listener in the same way as a closed headphone. Each side uses a 40 mm aluminium and magnesium driver with Focal’s M-shaped dome. The manufacturer specifies a 26-ohm impedance and an analogue connection, rather than wireless playback or USB audio. Open-back headphones can also leak sound to people nearby, which is worth considering for shared rooms. There is no battery, Bluetooth receiver or active noise cancellation to charge or configure. Pair the headphones with a suitable headphone output, DAC or amplifier. This listing is for the Hadenys headphones in brown, with exact-model packshots retained and standalone accessory and dark scene images removed.

Shure
Shure SE535-CL-EFS Wired Earphones — Clear
Clear wired SE535-CL-EFS earphones
The Shure SE535-CL-EFS is the clear wired version of the SE535 in-ear earphones, intended for personal listening and monitoring from a suitable headphone output. Each earpiece uses three balanced-armature drivers in a compact transparent housing. Shure specifies 36-ohm impedance and 119dB SPL per milliwatt sensitivity at 1kHz, with an 18Hz to 19kHz frequency range. Isolation is passive: selecting well-fitting sleeves creates a seal, rather than using electronic active noise cancellation. The detachable clear cable connects through gold-plated MMCX sockets and terminates in a 3.5mm plug. Its over-ear wireform helps route the cable securely, and the supplied 64-inch cable is approximately 1.63 metres long. The current UK EFS package includes foam and soft-flex sleeve sizes, additional sleeve styles, a carrying case and a quarter-inch adapter. This is not a wireless or Bluetooth bundle and does not include a wireless monitoring transmitter or receiver. It is also distinct from the red limited-edition model; the description and frequency figures refer to the standard clear SE535.

Bose
Bose QuietComfort Ultra Headphones (2nd Gen) — Black
Second-generation over-ear headphones, black
The Bose QuietComfort Ultra Headphones (2nd Gen) are over-ear wireless headphones finished in black, with a folding design and supplied carry case. This listing is for the second-generation model, not the original QuietComfort Ultra Headphones. CustomTune adapts the audio response to the wearer, while adjustable noise cancellation and Aware listening modes support different listening situations. Bose Immersive Audio creates spatialised playback, and the new Cinema Mode is designed for dialogue and video soundtracks. Bluetooth handles wireless audio from compatible sources, while USB-C also supports digital lossless audio through a suitable wired connection. The supplied 3.5 mm-to-2.5 mm cable provides an analogue listening alternative. Bose advertises up to 30 hours of battery life with Immersive Audio disabled, or up to 23 hours with it enabled; actual results depend on settings, volume and use. On-head detection can pause and resume playback, while controls manage volume, music and calls. The Bose app provides setup, equalisation and customisation. The box includes the headphones, carry case, analogue audio cable and USB-C-to-USB-C cable, but not a mains power adaptor. No water-resistance rating is claimed for this headphone listing.

Bowers & Wilkins
Bowers & Wilkins Px7 S3 Wireless Over-Ear Headphones – Canvas White
40 mm bio-cellulose drivers
The Bowers & Wilkins Px7 S3 in Canvas White combines an over-ear design with active noise cancellation and a choice of wireless or wired connections. Its two 40 mm bio-cellulose drivers work with dedicated digital processing and amplification. Bluetooth 5.3 supports codecs including aptX Lossless, aptX Adaptive, AAC and SBC, but the format used depends on the connected source and connection conditions. The Bowers & Wilkins Music app offers a five-band equaliser, allowing you to adjust the presentation to your preferences. An eight-microphone system supports noise cancellation and voice calls. Battery life is rated at up to 30 hours, with actual endurance dependent on the features in use; a 15-minute charge provides up to seven hours of playback. The package includes a carrying case and both USB-C to USB-C and USB-C to 3.5 mm cables.

Sennheiser
Sennheiser HDB 630 Wireless Over-Ear Headphones – Black
42 mm dynamic transducer in a closed-back design
The Sennheiser HDB 630 in Black is a closed-back, over-ear wireless headphone designed around a 42 mm dynamic transducer. Adaptive noise cancellation helps reduce background distractions, while parametric equalisation and crossfeed provide ways to tailor listening through the companion software. The included BTD 700 USB-C Bluetooth dongle adds aptX Adaptive transmission to compatible USB-C devices, rather than relying solely on a phone’s built-in Bluetooth codec support. Audio up to 24-bit/96 kHz is supported over USB-C and suitable aptX Adaptive connections. Battery endurance depends on the listening format: Sennheiser specifies up to 60 hours at standard resolution, or up to 45 hours with 24-bit/96 kHz aptX Adaptive playback through the BTD 700. Alongside the dongle, the box contains USB-C and 3.5 mm cables, an in-flight adaptor and a carrying case.

Chord Electronics
Chord Electronics Mojo 2 (4.4 mm) Portable DAC & Headphone Amplifier — Black
Updated version with one 3.5 mm and one 4.4 mm headphone socket
This updated Chord Electronics Mojo 2 combines a portable digital-to-analogue converter and headphone amplifier in a compact black aluminium enclosure. The version offered here has one 3.5 mm and one 4.4 mm headphone output, rather than the original model’s two 3.5 mm sockets. Digital sources can connect through USB-C, Micro-USB, optical or coaxial input, with a separate Micro-USB charging connection and switchable USB-C charging. Its FPGA-based processing includes four-band UHD DSP tone adjustment and a selectable crossfeed function, controlled through the coloured spherical buttons. Each headphone output stores its own volume and DSP settings when used individually. If both outputs are connected, the 4.4 mm output takes priority and its settings apply to both, so this is not two independently adjustable simultaneous headphone feeds. The built-in rechargeable battery supports portable use, while the device can also be used in desktop mode. The 4.4 mm connector is not described here as a balanced-output circuit.

Audeze
Audeze MM-100 Open-Back Planar Headphones – Black
90 mm planar-magnetic drivers
The Audeze MM-100 is a wired, open-back planar-magnetic headphone developed for music production and critical listening. Its 90 mm transducers use Fluxor magnet arrays and Fazor phase-management elements, within a chassis built from magnesium and steel with a spring-steel headband. The manufacturer specifies 18-ohm impedance and a weight of 475 g. The supplied cable can connect to either earcup, allowing the lead to sit on whichever side suits the desk or studio setup. Open cups permit sound leakage and do not provide isolation from surrounding noise, so they work best in a quieter listening space. A compatible headphone output is required; the MM-100 is not a Bluetooth headset and has no built-in microphone or rechargeable battery. This listing contains one Black headphone, not a full recording system.

AlphaTheta
AlphaTheta HDJ-F10 Black Wireless DJ Headphones
Wired, Bluetooth and compatible SonicLink listening modes
The AlphaTheta HDJ-F10 is a black closed-back DJ headphone offering wired listening, Bluetooth audio and SonicLink wireless operation with suitable compatible equipment. Forty-millimetre drivers provide a manufacturer-stated frequency range of five hertz to thirty kilohertz. SonicLink is the dedicated low-latency monitoring connection; Bluetooth is a separate listening mode and must not be described as having the same DJ-monitoring latency. This listing is the headphones-only HDJ-F10, not the HDJ-F10-TX bundle: the HP-TX01 transmitter is sold separately when required by the connected equipment. The manufacturer states up to nine hours of use with SonicLink or thirty hours with Bluetooth, with actual runtime depending on conditions. Noise-cancelling and transparency functions support different listening situations. Supplied accessories include a one-point-two-metre coiled audio cable, a six-point-three-millimetre adapter, a USB-C charging cable, spare ear pads and a carrying pouch. A straight audio cable is not listed among the official supplied accessories. Compatible playback equipment and any required transmitter are additional to these headphones.

Sony
Sony WH-1000XM6 Wireless Noise-Cancelling Headphones — Black
30 mm drivers in a closed-back over-ear design
The Sony WH-1000XM6 is a pair of wireless over-ear noise-cancelling headphones with 30 mm drivers and a closed-back design. This listing is for the black WH1000XM6B.CE7 version. Bluetooth 5.3 supports SBC, AAC, LDAC and LC3 audio formats, while multipoint connectivity allows connection to two devices. Sony specifies up to 30 hours of music playback with noise cancelling enabled, or up to 40 hours with it switched off; actual battery life depends on use and settings. A full USB charge takes approximately 3.5 hours. The headphones weigh approximately 254 g and include a detachable, single-sided 1.2 m headphone cable for wired listening. The ear units rotate flat and one folds towards the headband for storage in the supplied carrying case. A USB-A-to-USB-C charging cable is also included. Music playback figures are separate from call-time ratings; no continuous wireless audio or lossless Bluetooth claim is made.

Sennheiser
Sennheiser HD 660S2 Open-Back Headphones – Black
38 mm dynamic transducers
The Sennheiser HD 660S2 is a wired, open-back over-ear headphone with 38 mm dynamic transducers and 300-ohm impedance. The design refines the earlier HD 660 series with revised airflow and voice-coil construction, with the manufacturer describing extended sub-bass performance. This is not a headphone whose bass response stops at 70 Hz: the published frequency range is 8 Hz to 41.5 kHz. Open earcups allow sound leakage and do not provide closed-back isolation, so a quieter room is preferable. Detachable cable arrangements support 6.35 mm single-ended and 4.4 mm balanced connections, with a suitable source required for whichever output you choose. A capable headphone output is advisable for the 300-ohm load; no amplifier is included. The listing is the Black S2 version, not the original HD 660S.
