Just received mine from Amazon. Running my Kanas pro with 2 pin to MMCX adapters just fine. Sounds as good as they do while plugged in with my M11. Extremely comfortable, doesn't even feel like there is anything on/behind my ears because of how light the units are.

Hi
I just got mine and using a nokia 6.1 plus but i can't seem to connect them in TWS+ mode only as they daisy chaining. is there a special method for that? apparently the phone should be able to handle TWS+ but now I'm uncertain.

Your smartphone has a Qualcomm processor and Bluetooth 5.0. It should support TWS+.

For me its the opposite. I wish my FiiO's uTWS1 would go to Master/slave mode. They keep trying to re-synch all the time. It is annoying, and the streaming quality goes down for a moment too. No problems if I use 1 earpiece on its own.

I can't figure out how to change it.

Having already bought TRN BT20S (and ending up discarding it due to noise flooer) and BT20 (less noise floor but I suspect it does not support the independent connection for left and right earpiece), I'm not going to buy a third version of the same product. The noise floor on BT20S is simply unacceptable with my CIEMs (116db sensitivity) and the fact that this uses the same chip is really discouraging.

I hope in the future a new chip will come out, allowing this form factor to shine as it deserves. I find it absolutely perfect for custom in-ear monitors.

How is the volume going to be controlled with these (I remember reading that was one of the improvements over BT20S)?

Edit: if, on the other hand, the "Optimized output LRC network" that's described on the product page brings the noise floor on the same level as BT20, I might seriously consider buying these.
I am using my Shuoer Tape (sensitivity of 104db) and the gain increase on the UTWS1 is much quieter than than my B20s. So maybe they set this up similarly to the older B20 model. It may have less hiss with your iems.

I think the TRN BT20s is exactly the same as fiio... And Fiio may have just bought TRN... Or worse, they might have just copied and silenced TRN, and told TRN: I'm gonna copy you anyway since you didn't patent your design...

One bad thing about Chifi (and many Chinese manufacturers) is that they disregard environment impact, and disrespect intellectual property of any kind.

I feel for SOOOO sorry for TRN being bullied by the big Fiio brand R.I.P.

The beeps, and women voice sound promps are the same in the B20s and the UTWS1.

But I do find the UTWS1 quieter.

Nah they are the same. From another thread, two other members report they share one FCC ID.

I measured both under an audio analyzer, they are not the same performance wise. UTWS1 doesn't go as loud as BT20s and doesn't distort nearly as much.

You also assumed FiiO must be copying TRN without considering that TRN is probably the OEM for FiiO on this particular model, much like FiiO also OEM for other brands.

Thanks! That sounds like they are revised a bit by Fiio after the TRN design is adopted.

And I love your earbud thread by the way, I have mx985

Dear user,

The uTWS1 is manufactured by TRN, but it is different from the TRN's. We have made some improvement in the circuit part in order to reduce the bakground noise. But when pairiing with the high sensitivity headphone, the background noise may be noticeable still.

Best regards

Same OEM but different specifications, the Fiio has better amping and less ground noise.

Still slightly annoyed they couldnt find a better charging solution.

Magnetic plugs and cables adapters help in making it less annoying.
