Just wanted to make a quick update and pin this here so folks will see. While my unit still works fine, it seems like there are quite a number of feedback of folks having some QC/connection issues with this. Just have to go through the comments to see. I know it's a small sample size, but still feels like it's happening a bit more frequently then it should? So just be aware! Thanks!

This model have received quite mixed reviews. On one hand, I read that some find it perfectly fine. On the other, I read that it suffers from connection issues, charging issues, as well as issues from the removable mmcx, 2 pin, qdc cables. It seems that its almost based on luck whether or not you'll get a decent working unit

Great review as always, have you heard of the upcoming UTWS3 by fiio, its said to be coming with an amp and dac that's almost the same with the fiio BTR3k and BTR5. Hope to see you review it on this channel.

[hmm]

That was a sick intro Alex.
Love these, but aren’t they too big?p for your ears? They kinda look like a hearing device.

Nice vid man, you didnt encounter connection issue so far?

[vinmangubatc]

Nice looking earbud and solid review. Great Job

How does the mic perform at noisy places? Does it cancel environment noise clearly?

[PaulWasabii]

I was curious about this one, great review. I noticed the ZSTX in many of your shots, was that your favorite pairing? Being a Z1 fan, the ZSTX would have been my first choice also for outdoor use. Is it easy to find the button for play/pause?

Just bought these and found that the 2 pin connector doesn't work with my ciems as the sockets in them are recessed. 😫

[himeraji]

is there a difference with the IEMs/earbuds Fiio UTWS1 one? the design is very similar and the price is very affordable too

[GWS-]

No volume control on this pair? Thx for the great reviews you make.

[dqnizing]

Hi great review! I was wondering if it supports a recessed 2pin connector?

[BrioncedReviews]

Great review alex!! May I ask does this work for kz-zsx iems?

[jortuspelatus]

This or KZ's bluetooth adapter? Great review!

[Spidey]

Can the left and right be used independently (either left or right) ? Great, concise review btw👍🏻

Una pregunta, entre los TRN BT 20S y los BT20 hay mucha diferencia? Es que tengo muchas ansias de comprarme un adaptador Bluetooth pero justo ahora me costará tiempo obtener lo que necesito para comprarme los TRN BT20S, pero actualmente si tengo el dinero para comprarme los TRN BT20 (tengo 15 años xd)

Hi how are you? I just got Celest T1 and found someone said these are Same as the model you were reviewing so if I paid for US$29 in 2025 .. Did I Paid Too Much?! Is it still OK to keep or if I can return them should I just return them? Also is there any better products out there please?

[MrD]

I'm curious if you are able to turn them off when they out of the case? I would like to use them with my on-ear pair of Koss headphones and I don't want them to discharge when I'm not listening to music.

Wow may I ask what is the music app you use on your phone?
