The B400 sports four balanced armatures per earphone and costs £170. Is it worth the money? While there are seemingly endless options of cheap earphones in the sub-£30 sector, what can you get if you are looking to spend a bit more? The Brainwavz B400 might be something to consider, with four drivers per earphone and a price of just under £170. That puts the B400 in direct competition with 1MORE’s Quad Driver IEM – which, as the name suggests, also boast 4 drivers and now cost just under £130.

While the inclusion of four balanced armatures per earphone is definitely the headline-grabbing feature of the Brainwavz B400, there’s plenty of other aspects to the earphones as well – including the 3D printed driver housings, a pair of detachable MMCX cables that come in the box, and a total of 7 pairs of ear tips that are also included. Currently priced at £169.50, are these worth buying?
