What are the Brainwavz B400?
The Brainwavz B400 are quad-driver in-ear headphones. They have four micro drivers per earpiece – which is generous for any kind of earphone, let alone one costing £159.
Shure’s SE846 have four drivers, but cost £829. Ouch.
The number of drivers don’t mean a thing if sound quality is poor. Thankfully, Brainwavz’s B400 sound great – although their excessive warmth fails to highlight their great detail as much as we’d like.
