[FiiO UTWS5 2025/UTWS5] True Wireless Bluetooth Amplifier Is Officially Released!

[drewbadour]

Thanks for your input. Any particular reason for your opinion?
Without the adapter the fit might be tighter. I don't need compatibility with mmcx IEMs.
Should i choose the adapter route then i would get the L shaped adapter.

U12T shape would make it so you'd have to bend the adapter arms to fit in the case. With MMCX and adapter, you can just rotate the IEM and they sit in the case perfectly.

How does the charging system work on these how do you know when the case is charged ?
I plug it into usb power with the correct rating plug & the centre light glows bright with a slight pulse then after a while the light goes out. Is this correct ? The reason I ask is on the fiio site I read the light will always stay on while powered by the usb but this isn't the case with mine. Other than that I have figured out everything else & are very happy with the utws5. Thanks fiio for a good product.

I've only used wireless charging but if I recall correctly, it should pulse when it charges but then when its full the light stays on. I'll try it with the cable tonight and see if it changes.

Ok thanks. Dum question but what do you use for wireless charging.

 

[eswng679]

Just a generic wireless charging pad from Amazon. It works for a lot of devices.

Would say TinHiFi T4 or (with adapters) Aria, Starfield, S12.

S12 or Olina for sure.

S12 is regularly on sale for 130-140.
With Olina I'd highly recommend getting a Tanchjim Tanya to do the filter mod.

Olina

Thanks for the suggestions. With the exception of the olina’s; these were some IEM’s I was contemplating. I believe a couple are 2 pin only and I wasn’t sure how the adaptor was going to work out with fitment and I wasn’t seeing anything about tonal signature with the UTWS5 specifically.

Regarding the Olina with the filter mod; the thread I found with some info is a glorified Tolkien novel.
What’s the quick breakdown on the mod?
What’s to gain and what’s being done? I read something about filters and multiple vents I think…

Again thank you!

anyone know what the game mode does... UPDATE.. I found it on the website... thanks

Turning on the Game Mode can significantly improve the low latency in the Bluetooth transmission process.



Tested by FiiO Labs, the aptX Adaptive can improve the latency by about 27% while the aptX can improve by about 41%.

**When connecting the UTWS5 to the Mi 10 in aptX Adaptive codec, the measured latency goes up to 165ms with the Game Mode off, while the latency goes down to 121ms with the Game Mode on.

**When connecting the UTWS5 to the Huawei P20 in aptX codec, the measured latency goes up to 255ms with the Game Mode off, while the latency goes down to 150ms with the Game Mode on.

I noticed today when I put the charging case on charge via USB-C connection (with UTWS5's inside and already fully charged), my phone connected to the UTWS5 even though they should have been off.

Anyone else able to replicate that? Not the biggest deal ever but I figure it shouldn't be happening.

I've had a similar thing happen.

These are fun to listen to. Gotta love the freedom of 0 cables in the way.

@FiiO I would love if you awesome people designed a proper TWS adapter for just headphones. This obviously works but something a bit more powerful and more appropriate in terms of shape/geometry would do it perfectly.

I've had the UTWS5 for a few months now and I really feel its a big step up over the UTWS3 in sound, battery life, even the way the contact pins connect. You can match these with the best IEM you've got without worrying about the sound quality. Love that you don't have a master and a slave adapter anymore, you can use just one adapter at a time if you want. Overall, great stuff. Totally forgot about the updates, been using them with the stock firmware (1.3 something I think) since day 1, so I haven't even tested LHDC. Just updated, will give them another go for a few days.

Yes, it improves call quality.

just in case anyone is interested ... I can confirm the UTWS5 drives the Timeless 7hz quite well... and they fit in the case perfectly....

Dear friend,

Please check whether the charging box is out of power at that time? And please try to clean the charging pins to check again.

We apologize for any inconvenience in the meantime!

Best regards
