final B1 Multi Driver IEM


Request A Price Match

Balanced armature + dynamic driver

The B1 employs a total of two drivers: a balanced armature driver for high- and mid-range frequencies and a dynamic driver for bass. By dividing the sound frequency between two drivers, the B1 achieves a greater sense of clarity and definition. 

Stainless steel 

The B1 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. 

Ear hooks that eliminate cable touch noise

The B1 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.
