I finally got the two pins version.
And I will share some of my experiences with it below.

It's a little pity that the UTWS5 doesn't support the LDAC, but it got the aptX Adaptive, which is like a technology that will switch the audio codec between aptX HD and aptX ll automatically.

24bit 96kHz is supported.

Sound:
Pros: The noise floor of The UTWS5 is already very small, and is not audible through my 5 BAs iems.
Cons: The sound quality is not as good as my BTR5 (maybe it's because the BTR5 got a LDAC codec?). The most obvious characteristic is in extremely bass(sub bass). With my 5 BAs iems, I got less sub bass on the UTWS5 than the BTR5, but this characteristic is good for my hybrid and dynamic driver iems---less bass for clearer sound.

Gaming:
I played the CarX Rally with the UTWS5. The latency problem still exists, but it has improved a lot compared to BTR5. And the new firmware + new version of FiiO Control add a game mode, which can further improve the latency problem.

The function of Ambient Sound is good, it makes my iems into hearing aids (lol), however, the sense of reality of FiiO's Ambient Sound is not as good as Sony's, and I hope that the next generation can improve it (would be better to add ANC).

The BTR5 has already increased in price, and it is said that the UTWS5 may also increase in price in the future. So I think now is the best time to buy it.
