Product Overview

Sennheiser IE 900 are the company's latest flagship in-ear audiophile earphones. They feature Sennheiser's proprietary X3R transducer with a unique triple-chamber absorber system.
The IE 900's earbuds are each crafted from a single block of aluminum. Its triple-chamber absorber system is able to make high-frequency sounds clearer by removing the energy from masking resonances. Sennheiser claims that the IE 900's single-driver design offers greater fidelity compared to multi-driver headphones, thanks to this triple-chamber absorber design.
With the IE 900, Sennheiser has included three switchable cables, allowing the owner to switch between 2.5mm, 3.5mm, and 4.4mm connectors.

The Sennheiser IE 900 are among the best-sounding in-ear headphones we've ever tested. Aimed squarely at the audiophile market, these are wired earbuds for the most discerning of ears. Much attention to detail has gone into making of these buds, from the aluminum housings to the microfibre cleaning cloth included in the box.

Reviewers from whathifi have found the following***:
Sennheiser IE 900 have a single driver rather than the more fashionable multiple unit approach that many rivals take. A single unit has no need for a crossover of any sort, so avoids the innate distortion of such a circuit. These earphones are comfortable in use thanks to careful shaping, a good range of eartips and the security provided by the cable folding around the ears.

Pros
  • Clean, open sound
  • Excellent source and amplification quality
  • Easy to use
Cons
  • No in-line remote
