That's a good workaround idea, @Ocelitgol especially if their use case isn't latency sensitive.

@Nokduangrach FWIW the QCC3020 used in the UTWS3 definitely does not support what is commonly referred to as multipoint pairing. I will also stress that basically no TWS adapters have chipsets with multipoint ATM. Some of the larger BT adapters, e.g. my ES100 do. As a compromise, although not exactly helpful for your use case, I'm urging @FiiO Willson to suggest that the engineering team revise the connection handshake behavior to accept/change to the new device on a new connection request instead of rejecting any new requests if a device is already connected. This will at least make it faster and easier to switch between devices in lieu of multipoint. This is common (Pixel Buds, Sony wf1000, etc. all work this way).
Multipoint pairing is indeed very desirable to give the UTWS lineup a completed features package (plus some improvement on the software side).

I also remember that Samsung has some kind of seamless switch between different Samsung devices (there is an option for that on the Galaxy Buds Plus app). But to be fair, Samsung did use their own chip for that (correct me if I am wrong).

Here's the gap:

Also, I noticed that the dongles wouldn't charge if I don't charge the charging case. Which is weird, because i think the charging case is fully topped off.

@FiiO Willson can you confirm if i need to fully close the charging case to activate charging? I am able to charge the dongles with the case slightly open only if i also charge the charging case.

Thanks!
Yes, turning off box charging is the right thing to do.
Opening the box a little bit is right at the threshold of the box's judgement so that it will not work steadily. Our experiments were also tested with the box turned all the way off.

I connected my utws3 to samsung s9+ but i am unable to view the same via fiio control app. Does any one else face the same.?

Also i have 5 different fiio utws3 names showing up in my phone while scanning via bluetooth of which 4 are paired. I am unable to pair the 5th one.

Please find the screenshots below. Does anyone know how to view and control utws3 via fiio control app with samsung s9+?

Hello
Please try refreshing here,
微信图片_20210125090611.png

if not, you need to kill the FiiO Contral APP(Kill,not Only Close it) and reopen it again.
You don't need to connect LE-UTWS3V0.2.45L.
Also, there is a more stable version of V0.2.46 which you are advised to upgrade.

I have used Fiio utws3 daily as my earbud on the go. There is one downside which is it does not support multi-devices. Is it? If I misunderstood, please explain me how to pair 2 devices at the same time.
In my case, every Sunday from 1-6pm,I have an online class which I connected my Fiio utws3 with macbook Pro to listen teaching. However, I also want to get a call from my IPhone. How should I do? At the moment I wear Bose qc35 for an online class instead. Bose qc35 (1st generation which is released 5 years ago) can respond both devices spontaneously.
Hi
This issue has also been reported by users and will be evaluated.
We will see if there is a better way to improve the user experience, thank you.

Dear friend,


Please try to turn on the location function in your mobile phone and check again. Remember not to use the FiiO Music app and FiiO Control app at the same time.

Best regards

Hi all - long time lurker, second time poster here. Recently got my hands on a set of UTWS3s with the hope of running my FH7s off of them. Unfortunately, I seem to be having a bit of an issue with them, and wanted to see if I had a dud pair or if anyone else could confirm what I was seeing...

When I went to connect the IEMs to the UTWS3, they wouldn't click into place, and left a substantial gap between in the MMCX connection. The gap is substantially bigger on the right UTWS3 than the left.

The connection seemed to have a very weak hold on the IEM, so I took a bit of a closer look, and it looks like the male connector's pin on the UTWS3 on the right ear adapter is too big for the female connector, forcing the center pin socket apart...

For reference, here's a side-by-side shot with a Sony MMCX cable on the left and the UTWS3 on the right.

Can anyone else check if their IEM pin socket seems to have widened after popping them on the UTWS3? Because if I'm not completely crazy, and this is the case for other UTWS3s, that's... bad. IEM-killer bad, in the long run.

@FiiO Willson, any response from Fiio on this would also be appreciated.

Edit: Took the left IEM off of the left adapter, checked the IEM connector - looked ok. Popped it on to the right adapter, took it off, checked it - yep, IEM pin socket got forced way wider. Think that's as much as I'm willing to experiment with the UTWS3 with my own IEMs...
Hi, thank you for your feedback, I will ask the after sales team to confirm the issue and will have them contact you.
Dear friend,

Does the output work correctly? There is a tolerance range for the MMCX connector. So the connection with some unit may not be that tight without gap.
You could try to connect again to check if it helps?

I borrowed a friend’s phone to do the update today, it worked well on the L side, but on the R side I’m experiencing similar issues. Sometimes the update actually gets to 100% and nearly finishes, but the app tells me “Update Failed. Please try again”, and then the problems start again. Seems the R side is basically unable to hold a connection while the L side is fine.

Real bummer, these were great while they were working.
Dear friend,

When updating the firmware for the R side, what's the status of the L side?

Have you turned off the L side at that time?

Best regards

I just got the utws3 last weekend and tested them (updated to 0.26 firmware) with my Andromeda S. I am a bit disappointed. Source is a S20Ultra phone on AptX, streaming 16-bit 48k lossly music. The Andromeda S just loss all sparkle upside and the low end bass. The Andromeda S paired with the utws3 actually sounds worse than MTW2.0 with aptX, which is surprising to me. When I connect the Andromeda S back to 3.5mm and a Zortello DAC, all its glory were back.

The Andromeda S also sounded great with the Shanling MW200, which is I believe to be the equivalent of the Fiio LC-BT2, abeit on LDAC.

maybe you need something like 0.1 output impedance :thinking:

The output works in terms of sound output - the problem is
  • The mmcx retaining ring does not fully enter into the IEM, so theres nothing really preventing the IEM from disconnecting
  • The IEM female mmcx connector's pin socket is forced so wide apart that it no longer works with any other mmcx male connector, like the stock FH7 cable

mine updated, even if the process is weird, they sound OK, clearly the BTR5 demolishes them.

But with my Blessing 2 ? they feel slightly underpowered but the most worrying part is that the soundstage compared to my sony A35 or BTR5 is around 10%, everything sounds compressed and inside my head.

anyone here facing firmware upgrade issues? mine doesnt update, i have followed every steps from the manual and upon updating the progress bar just freezes there.
Dear friend,

Did you try to turn off the other unit when updating one of the unit but the issue still remains? You could hold the button in the UTWS3 for about 5s to turn it off.(You could hear 'Power off' notification sound)

Best regards
