Happily, the Sennheiser IE600 don’t so much ‘beat’ the best true wireless in-ears around ‘wipe the floor’ with them. Mainstream consumers gave up on them a while ago – at almost exactly the same time as smartphone manufacturers gave up on headphone sockets, in fact. In the box with the Sennheiser IE 600 buds are two cables that interface with the MMCX connectors on the buds. Even in the compact world of the human ear canal, having one driver to handle everything is an engineering challenge in itself. The bass is balanced well and doesn't bleed into the mid-range, ensuring vocals come through clearly with plenty of character.

This is an admirable feat, especially with their line of IEMs, and thankfully the IE 600 gives you that same prestige. If you are more about your shoegaze than your symphonies, you could well find you prefer the cheaper earphone because it has a presentation that so effortlessly ties into smaller and more focussed styles of music.The nozzle of the driver housings includes the dual resonator chambers that are key to high-fidelity sound. I'm amazed at how quickly notes recover because the attack and decay are so fast for a dynamic driver. Den perfekte lyd og de anstrengelser, Sennheiser gør sig for at opnå den - det er historien om IE 600. It uses pair of painstakingly developed 7mm extra wide-range ‘TrueResponse’ transducers to deliver the sound. Our high-tech AMLOY ZR01 is used in components for aerospace and MedTech applications that require ultra-high precision and robustness.

Two different styles of earbud tips — silicone and memory foam — are provided in three sizes to establish a comfortable seal in any ear.The IE 600 housing is fabricated using metal-powder-based 3D printing that can create any shape imaginable within tight tolerances. The IE600 integrates dual two-chamber absorbers (D2CA) which capture and attenuate these masking frequencies, revealing even the finest textures of your music. Produced using a 3D printing process, the housings are crafted from ZR01 amorphous zirconium, a super-hard metal that has a glass-like atomic structure and is three times as strong and resistant to bending as high-quality steel.
