The R1 is the worlds first balanced armature type earphone to use Ruby as an Acoustical Filter. It is as impressive in performance as it is in aesthetics and design.
The extremely hard material Ruby, used as an acoustic filter greatly suppresses stray resonances within the unit to provide an incredible depth and clarity across the frequency spectrum. It gives a sound stage and dynamic range never heard before in a canal type earphone.
The R1 comes with mulitple silicon ear pieces and beautifully crafted genuine leather pouch to carry your priced possession around.
