Brainwavz B400 Review, Quad Driver IEMs for $190

Brainwavz B400 Review

Typically, in-ear monitors that boast three, four, and five plus drivers are quite expensive with top tier brands retailing these buds upwards of $500 ( and more commonly at $1000). Brainwavz is making, well waves, with their new four-driver IEM for a mere $190. Get the low-down on these buds in our Brainwavz B400 Review.

Brainwavz B400 Review – Fit/Feel

Off the bat I was surprised at how incredibly comfortable these IEMs are. While I’m partial to slimmer ear bud housings, like that of Westone, I found Brainwavz B400 to be rather light and fit perfectly in my ears which is normally problematic for me since I have a tragus piercing. The B400 is built like many other IEMs, in that it’s an over-ear hook. The cable affixed to each housing is of durable material, but not the kind that feels heavy or hard to bend. The cable is quite flexible and easy to maneuver and it is detachable using an MMCX connection. This means these buds can be made wireless with an MMCX-based Bluetooth cable available from both Westone (Audio46, Amazon) and Shure (Audio46, Amazon).

As for stability, the earbuds fit really well. The B400s include five different size silicone ear tips and Comply T-100 Premium Isolation tips in size medium. I’m wearing the smallest size and it fits like a glove. I even shook my head from side to side and found that these babies weren’t going anywhere. This impeccable fit is due to Brainwavz incorporating the latest in 3D printing technology to craft their housings. The main shells are printed using state-of-the-art liquid Resin 3D printers, enabling a shape not possible by normal manufacturing methods.

Brainwavz B400 Review – Features

As I already mentioned, these buds use an MMCX connection which means the cable can be swapped for another cable, be it oxygen-free copper or Bluetooth. I’m using the cable with an in-line remote and mic. My only vice is that this controller is situated too high on the cable. I find it perched rather closer to my cheek instead of my mouth. I think if the mic and controller were placed just a few inches lower the controller would feel more convenient to use.

Brainwavz B400 Review – Sound

Overall, these buds provide a balanced tone that’s fun to listen to it. The balanced armatures provide audio that is not overly critical but allows for some oomph and warmth in the low end and rolls off the top for a relaxed and smooth listening experience. The treble and highs are impressive. The balanced armatures work together to create what is a full-bodied upper range that is neither bright nor thin. Vocals are relayed with clarity and precision that can rival other quad drivers.

The mids are quite lush in the B400 thanks to two drivers dedicated to the mids. This provides a robust, rounded, and smooth sound for a wholesome listening experience.

The bass is present and features a low end with a slight boost to it. It’s not particularly full of depth, but its presence is nice to have. The B400s aren’t as flat as other balanced armature IEMs, but I think this makes for an experience that is more enjoyable than critical. Sub-bass is also present and better than expected and plays nicely into the overall lively spirit of the earbuds. Each element of music is nicely spaced apart. The lows are nice and full, especially for BA-based buds. The mids are positioned right behind the vocals which I find to be delivered in a manner that is smooth for listeners, but still stays true to the recordings.

Brainwavz B400 Review – Overview

These IEMs are well worth the $190. At this price point Brainwavz provides a comfortable chassis that supports lush and lively playback complete with detailed vocals, mids and highs, along with a subtle bass response. It makes for a delightful listening experience.

Brainwavz B400 is available from for $189.99 in colors Frosty (clear), Black, Cosmic Black (black with glitter), Crimson Red, and Blue Knight.
