Sennheiser’s IE 900 in-ear headphones are a purist design, engineered with the singular purpose of offering the best sound quality possible at this level. Technical highlights include a single 7mm drive unit per earbud, an intricately machined aluminium casing, and the use of some clever resonance chambers inside that casing to improve the driver’s frequency response.
Premium wired in-ears are less common than they used
