Tested briefly on poco f4gt , f4 or x4gt amd see always returning to adaptive setting in lhdc developer options. In your phone its on balanced. Interesting. Is it really locks on different options?. Seem not. But today tested without utws5 connected, only bluetooth on. This could be the reason

Please, test again with your UTWS5 connected and report. Can you set it to LHDC 900 kbps in your Developer settings? Does it keep the setting? I mean, if you set it, exit the Developer settings and return back in, what do you see? LHDC 900 or LHDC Balanced?

Thank you

Dont have utws5 with myself today but tomorrow will so also make a test you ask with pocco phones. Ofcourse if nobody will till then. For me it is also interesting to know is it working and how it works with lhdc

Thank you, looking forward to your observations! Please, also tell the phone you are using, Android and MIUI version.

Have you checked?

Have you checked?

Hey, sorry today was a little too busy so had no chance to do it , but tomorrow really planing to do this and will post it here. Sorry for that

 

[MariusAB]

Have you checked?

So tested today as said. Interesting.
Tested with poco f4 , f4 gt, xiaomi 11 pro. No telephone stays on 900 kbps option. After setting and going out and going back i saw 500/560 option, but even then f4gt was not playing sound ( it was silent) , and only till i set to 400 kbps it played audio ( f4 played on 500/560). Also on adaptive option it was playing. It was on Miu 13.0.02 and 4 versions.
But also checked on mi pad 5 ( Miu13.0.6)
It stays on 900 kbps option and plays audio normally. So seems not utws5 problem but poco and xiaomi phones implementation. Don't know why there is no support for highest bitrates.
Also in all devices it goes to aptx adaptive as default if disconnected.

Thank you very much for this testing!

So, @FiiO can you please clarify:

- Why is the UTWS5 going up to max 500/560 kbps on the following Xiaomi phones: POCO F2 Pro, POCO F4, POCO F4 GT, Mi 11 PRO?
- I am running MIUI Global 13.0.4, the other member is running MIUI 13.0.2. Which MIUI version are you running, @FiiO ?
- Does this have to do with your implementation of the LHDC or with MIUI?

Thank you

PS: On my POCO F2 Pro, LHDC goes up to 500/560 kbps only if I will set the sample rate to 44.1 or 48.0 kHz. The phone defaults at 96.0 kHz, in which case LHDC plays only at Best Effort (Auto bit rate). At any other setting, no sound plays.

Got em in yesterday for my A12ts. Sounds surprisingly good with aptxHD. Unfortunately, LHDC doesn't work on my device (Pixel 6).

Happy listening, yes with aptx hd is not maximum you can get but i myself was listening long time with aptx only and was quite happy. Utws sounds really good with all iems , exept too warm or bassy for my taste. But it's really one of the best products fiio made. And you was not afraid to put your iems that cost so much more and still happy with outcome. That's nice

Yea I was honestly worried I would be disappointed by it coming from using a DAP but genuinely they sound really good. Certainly are bassy so I swapped to the M15 modules and it helped a bit with that (I like a bit more bass as I primarily use my IEMs for working out). I haven't used bluetooth in-ears in so long that I figured they were still terrible on android but I am quite impressed with how rapidly they connect to my phone once they are out of the case. Also with how little the latency is. Overall 9/10 product, just wish the case was a little bigger as it barely fits the A12ts.

Does it default to aptx adaptive on mi pad too?

This i haven't checked on mi pad device but perhaps have possibility to check soon. So will post here

Dear friend,

The UTWS5 does not support 900kbps currently. But we will try to assess about that in later firmware update.

Best regards

It sounds quite bad on aptx on Samsung S10, like a thin, cheap, hollow, boxy sound with poor separation and weak bass. On bluetooth 5.0 on Windows, it sounds noticeably better. Unfortunately, I don't have bluetooth 5.2 nor aptx adaptive compatible players. I didn't know it sounded that bad on aptx codec. Sounds like cheap $10 buds on aptx on Samsung S10.

Thank you for confirming and clarifying this matter!

Personally, I am very happy with the 2 pairs of the UTWS5 I own. I used to listen with aptX Adaptive and it was great, now listening with LHDC, sounds even better!

Looking forward to the next firmware update
