Brainwavz B400 Giveaway

The Brainwavz B400 is the company’s top multi-driver monitor, retails currently for $169.58 on their online store and yes, we are offering it in our first ever giveaway in partnership with Brainwavz.

Here is a brief reminder of why their flagship B400 monitor has been positively received by the audiophile community. If you wish to read our full review of the B400 you can click here.

B400 Technical Specifications

  • Drivers: Quad Balanced Armature
  • Rated Impedance: 30Ω
  • Frequency Range: 10 Hz – 40 kHz
  • Sensitivity: 115dB
  • Cable: Detachable MMCX
  • Plug: 3.5 mm, Gold plated


The B400 is a quad balanced armature driver IEM with 1 BA dedicated for the low-end 2 for the mids and one BA for the highs. All four of the drivers are Knowles drivers.

The internal wiring is litz wire (gauge unknown) and all the soldering is done using Kester Solder which is a very nice grade of soldering for keeping contaminants out and retaining maximum conductivity (if applied correctly).

3D Printing

This is also the first time Brainwavz have used a 3D printer in the manufacturing process of their IEMs. The original concept was metal injection molded shells much like you see with RHA and Campfire Audio but for some reason, the 3D printer process became more viable.

The additional bonus of this process is the price point which became substantially lowered as a result of the switching in production techniques.

The use of a 3D printing process seems a smart move for both production consistency and pricing. The design of the B400 is really perfect for comfort and seal and definitely one of the better ones at this price point.

The B400 is a smooth sounding balanced and easy going quad BA IEM. I like the tuning from Brainwavz and at this price point, you really can’t fault its performance. It is a strong choice for vocals with a bass response that isn’t lacking makes it a suitable choice for breathy female vocals and some genres of EDM.

The detail is on point though the only thing missing is perhaps a little more treble extension just to give percussion timbre a bit more life.
