final tuned the B3 with an emphasis on clarity. It’s the perfect IEM for listeners who want to hear the timbre and definition of each instrument, whether in live recordings, the vocals of pop tracks, or EDM. 

Stainless steel 

The B3 features a highly resilient and durable stainless steel housing. Created by metal injection molding (MIM), the chassis adopts an ergonomic shape that is hard to produce using traditional methods of molding.

Balanced armature driver 

The B3 employs two balanced armature drivers, one for the high frequency band, and one for the mids and bass.

Ear hooks that eliminate cable touch noise

The B3 uses an ergonomically designed ear hook that accommodates a vast range of ear shapes and sizes. The design also alleviates cable touch noise, the rustling sound that occurs when the cable rubs against your body.

Silicon carrying case 

Safely store the earphones and cable in the included carrying case, which is protected by a dome-shaped silicone lid.
