You may question the necessity for such expensive earphones (relatively speaking). Here are some jot points to get your inner Audiophile salivating:
A) Audeze products are Engineered and handmade in Costa Mesa, California by Sankar Thiagasamudram and the team.
B) They are oepn-back planar magnetic earphones which let sound in. This creates a more spacious listening experience.
C) They stand out from the crowd.
D) They make for a unique Christmas gift for someone looking into a fresh set of earphones. Heck, drop your Bose SoundSports, PowerBeats Pro or Apple Airpods and try something truly DIFFERENT!
(P.S. Audeze do offer a Bluetooth adapter at additional cost if you really need wireless audio)
The technical stuff:
Fluxor: double the flux density for the same size neodymium magnet.
Uniforce diaphragm: removes a lot of distortion by creating a uniform flux density across the diaphragm it self. This is achieved by altering the diaphragm trays to match the flux density variation across the diaphragm, so when the diaphragm moves up and down to create sound, it stays completely uniform.
