BQEYZ está disponível para comprar agora, alguém vai fazer isso?
my bad, Topaz!
Ah the Topaz, I think we have to wait for some first adopter reviews, as it was just launched.
Speaking about BQEYZ, their last model, the BQEYZ Autumn, is quite a nice midFI single DD set with an innovative magnetic swappable filter design. You just place the magnetic stick thing near the filter and it will attract the filter out. No need to screw things on which takes time and may also cause wear and tear.
Graph of the Autumn via IEC711 compliant coupler. The 8 kHz area is a coupler artefact peak.
The tuning filters here work, and ain't gimmicks. While the filters appear to only affect the bass region on graphs, the ears perceive the entire frequency spectrum as a whole, so changes in the bass will cause a "see saw" effect on the treble region and vice versa.
The grey filters (AKA bass filters) give a V-shaped sound signature. Bass is just a level shy of bona fide basshead levels.
The gold filters (AKA balanced) are the default filters, and provide a U-shaped balanced sound, as per its namesake and is probably the most all-rounded configuration that most folks should appreciate.
The silver filters (AKA treble filters) give a cold neutral tuning with added clarity and micro-details with a neutral bass.
Micro-details are above average, though there might be some multi BA/hybrid competitors with better resolution at this price point. Soundstage on the BQEYZ Autumn is excellent, with good height and width. This aids instrument separation with no congestion noted even on busy tracks. Imaging is decent but not class-leading.
The Autumn have good instrumental timbre, and are quite solid in build.
Some nitpicks are: the Autumn has an occasional glare at the 5 kHz region, and scales better with amping (impedance is a bit high for an IEM at 46 ohms). Isolation is also below average.
Compared to some midFI single DD luminaries, the Tanchjim Oxygen have better technicalities and resolution, but is more expensive and has a poorer fit (short nozzles). Note weight is also thinner on the Oxygen. The Autumn are slightly better than the Moondrop KATO in terms of technicalities, and the 3 tuning options give more versatility than the 2 screw on nozzle configs on the KATO (which are very subtle changes in sound signature).

It has the same driver configuration as the KZ ZEX, which is kind of interesting. It looks handsome enough, too.
Very wonky FRs, the MD4 is dead on arrival if it sounds like this.They are very close to my own measurements.

There is definitely no 'burn-in' at the factory.
Haha, nice observation!
Wandering at what price range it would be released. Hoping it will be in the he400se territory, but that's highly unlikely.Incoming Moondrop planar:

Is squeezing more peaks in, really a good way to smooth out your FR?
By contrast the Shimin Li graph looks really nice.
Talking of planars, heres Trn Kirin, a planar IEM with tuning nozzles.
A planar that emphasises technical proficiency with a clean tuning. Some might say boring yes...
I just want to see what the technical limit is of this planar IEM driver that's doing the rounds and I think Moondrop could bring that out.
