Sennheiser IE 600 Wired In-Ear Earphones

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.
