Probably the most interesting thing about the Q2 is that it comes with your typical MMCX connectors, which allows you to swap between a Bluetooth TWS experience and a traditional wired connection.

Unfortunately, that’s pretty much where my praises for the Q2 end. Don’t get me wrong, it’s not an outright bad set of IEMs, but the tuning leaves a lot to be desired especially in the higher frequencies, where it’s sharp and fatiguing for longer listening sessions. Not to mention the presence of that thin, plasticky texturing to the notes that I commonly refer to as “BA timbre”, that the Q2 exhibits pretty badly. The usual suspects of other generic BA IEMs are also here; sub-par bass response without proper downward extension, borderline-shouty upper midrange and lack of upward treble extension as well.

It’s interesting to see a TWS IEM using BAs (a rarity in this market), but ultimately it’s not about what drivers you use but how you use them. And for the Q2, the implementation is nothing special.

Good lord, why.

Look, I get it. Sometimes you want some bass. There’s no shame in being a basshead even within the audiophile community, and a little low-end thump never hurt anybody.

The YH623 on the other hand, is just bass. There is virtually nothing to balance out that nearly 20 decibel boost in the low frequencies; no treble spike, no boosted midrange, nothing. The YH623 is a pure, shameless, downright dirty set of “basshead” IEMs that bleeds harder than almost every other IEM I’ve tried. Instruments are overshadowed, vocals are drowned out, and percussions so blunted that they sound more like a pillow fight that anything resembling struck wood.

I don’t know who this is made for, so maybe the YH623 could be for you. But for anyone who values any semblance of balance in their sound, stay far away.
