Brainwavz B400 channel imbalance:
"...I tried many measurements, pulling the buds out of the tube, putting them in again in different positions, the same position, opposite position between L & R, etc. Within a tiny fraction, the responses remained the same as the ones shown on this graph.

I tried swapping the cables from L to R as well. Same result, so it's nothing to do with the cable…"

I'd say: poor quality control! They'll go back.

I had a slight channel imbalance in the demo pair I have. It turned out to be the source.

I heard it in my case, hence I had them tested. Source works for other iems fine. Swapping channels would have revealed faulty source.

I would have swapped channels to check, but I make it a point never to remove mmcx cables on IEMs that aren’t mine. The one time I do will be the one time there is a problem. These were loaners, so I had to test it other ways.

Brainwavz B400 factory improvements according to their customer service: There were some manufacturing improvements made and there were some slight changes to the appearance and finish of the shell. The accessories all remain the same.

In all fairness, every company has made a dud or two. How quickly they take care of it and how much hassle you have to go through to get it taken care of is what differentiates the good companies from the chaff.

Do you think there are better options under 40$ on amazon that can have same detail retrieval as zs6 and soundstage but with less aggressive treble?
I'a actually training my ear to aggressive treble and i'm quite ok, but i was wondering if there are technically better options (apart the v80, excluded from my list)

Tin audio t2?

**** NY-06, BQEYZ K2 & KC2 are all technically better options without the aggressive treble that stays under $50.

How do they compare to the RevoNext RN-QT2? Do they have a similar sound signature to the QT2. Just curious...

Revonext QT2 has an aggresive treble and is more similar to the Zs6 than not.

If you want a reference signature under $50 the Tin Audio T2 or BQEYZ Kc2 are your best bets. Tin Audio will take a bit of modding to alter the bass or Kc2 is good out of the box.

Right now for me, I'd have a hard time beating the BQEYZ Kc2 for the money.

Very informative, thanks!

Here is an interesting review of three USB headphone dongles for the Google Pixel. The results are pretty bad. The comments do mention that Apple's dongle is better

honestly surprised that the VE DAC output measured that low but then have very low impedance despite VE saying its for high-impedance earbuds. That low-impedance is nice for sensitive IEMs, but the low SINADs kinda ruins it. For 10 bux though, not really much of a loss, too cheap to mention.
