Ok here is the graph.

Usual disclaimers:
The graph below is generated using the Vibro Veritas coupler and ARTA software. Ken Ball (ALO/Campfire) graciously provided me with measurement data which I have used to recalibrate my Veritas so that it mimics an IEC 711 measurement standard (Ken uses two separate BK ear simulators, we measured the same set of IEMs, and I built my calibration curve from shared data). I do not claim that this data is 100% accurate, but it is very consistent, and is as close as I can get to the IEC 711 standard on my budget.

I do not claim that the measurements are in any way more accurate than anyone else's, but they have been proven to be consistent and I think they should be enough to give a reasonable idea of response - especially if you've followed any of my other reviews. When measuring I used the included foam tips (so medium bore) - and the reason I use foam instead of silicone is for the very consistent seal and placement depth in the coupler. I use the same amp (E11K) for all my measurements - and output is under 1 ohm.



Things to note
  1. Incredibly good channel matching - this is about as good as it gets folks. I had to check a few times to see if I'd measured the same earpiece by mistake!
  2. Nice mid-bass hump and good sub bass extension (they have a decent amount of thump)
  3. Bass matches natural peak in the upper-mids
  4. Really good treble extension
Hmmm the graph looks really interesting no noticeable/heavy peak or fall and 3-5khz frequencies are exactly as you like ( i think) .

More color options

From top to bottom
- Blue Knight
- Punk Pink
- Cosmic Black
- Green Rage
- Berry Purple

The lighting and camera on my phone make the blue and purple almost look the same but they are actually quite different.

I Love the Green Rage and the Punk Pink, both represent the two different sides of my personality :wink:

Yes! Green! Yes!!! :alien: :thumbsup:

I cannot express how happy you make me with this colour choice that unfortunately not many companies offer. Clark Cent, you better watch out!


By the way, as I already told Pandora some time ago, it would be nice to offer the B200 in one or two additional colours as well (e.g. Brainwavz' "signature" red colour and grey or white) to set it visually apart from the B100 and B150.

Cool ! Amazing color choices! Expect the sound to be even more amazing ! Certainly an upgrade in bass from my Brainwavz B2's !

Very interesting stuff, I'm really looking forward to more impressions on these.

I've been waiting for a long time for Brainwavz to step up their game and when they do I'm late to the party ha ha :wink:

...and the B400 still need some vital info from Raz (eg price etc) before being able to write the review :wink:
Yeah, I'm optimistic with all the initial reactions & updates, but I am tempering that excitement until I see an actual price.

I’m embargoed on the Simgot for about another week, and the B400 still need some vital info from Raz (eg price etc) before being able to write the review :wink:

Can try and post a graph later tonight though

That's... a surprisingly affordable price.

Brainwavz are still rocking the great price-performance ratio they re-introduced with the B100 and B200. Nice. Really nice. :relaxed:

However - that got me thinking why it is priced below the B200 (whose MSRP was $199) until I looked on your website and realised that the B200 is now only $119.50, which is an unbelievably low price for this great little IEM. Brainwavz is going strong and putting out great quality while not asking big bucks. Great job, guys.

Thats a ridiculous price Razz! And I mean in a good way. I was honestly expecting something with a "3" in front of it. Hats off to Brainwavz - entered the higher end at an affordable price. The only earphone which comes close at this level (IMO and with what I've personally heard) is the Alcalir Curve. Seriously good value.
