[FiiO]

Hey @FiiO , I'm slightly confused. I've got an Xperia 1 II and I see there's 2 options when I want to pair - Fiio UTWS 3 L/R and then there's LE-UTWS3V0.2.45L/R. What's the difference, because I tried them both and they seem to work?

Which is better?

Dear friend,

The option begins with 'FiiO' is general Bluetooth connection. The option begins with ‘LE’is BLE connection which is used for APP control mainly. For more information about BLE, you could read: https://en.wikipedia.org/wiki/Bluetooth_Low_Energy

So basically I need to use the Fiio one. Nice. By the way - since we are already seeing Aptx HD (B&W pi7) and even full-on LDAC (new sony 1000xm4s) true wireless IEMs, should we expect a new version of this UTWS product line in the near future with LDAC, possibly? That would be incredible! (+ also an option to passthrough ambient sound would be very useful)

Great idea! Is it possible to build ANC into a device like the UTSW3? Perhaps with microphones built into it and then adding the inverse wave to what’s being fed into the IEMs

We covered the topic on LDAC on TWS adapter on another thread - I think the current situation is that we need to wait for Sony to update the LDAC's SDK for TWS in order for other manufacturers to develop their own TWS with LDAC.

ANC is a firm NO. ANC needs to tune to specific transducer' FR curve in order for it to work properly. Since UTWS3 is not made to only work with any single earphone model (which come with all different FR curve), it is not feasible to implement ANC.

Dear friend,

If you don't mind, you could check this explanation from James in Weibo about TWS with LDAC using Google translation first : https://weibo.com/2388602863/Kj52celzE
Currently, our TWS with Qualcomm chip could not support LDAC Bluetooth codec still.

What's the polarity of the UTWS3 2 Pin version? Does it have the same polarity as the UTWS1?

Dear friend,

Yes, same as the UTWS1.

Got new units, these ones work finally, well... kind of...

The pairing still took 4 attempts to connect both L and R sides, the Fiio apps says they are disconnected but I can control the units from there.

Im using the VE8 earphones and unfortunately the pairing is not good, they sound lifeless. The Fiio control app only offers 3 EQ presets!!! only 3!! I cant find a way to customize it, is it possible?

I know is a bit unfair to compare them with my DACs or even my Fiio amps but so far the sound is not great, even my sony wf 1000xm3 sound way better... and we are talking 200dls vs 2.7K.......... The lows are gone ( my beloved chello sounds like an ukulele) and the highs lack any spackle.

I will try to make them come back to life, I hope is possible with an additional app or something.

 

[AllenShrz]

Double post update.

On android is much easer to find apps that bring back life to my V8. The lows and highs now may not be as refined as with the mojo but now they are totally serviceable.

For me is so much better to use a custom IEM than any TWE, just because of the fit. Your headphones have NC? that's cute, my earphones block absolutely everything and dont change the audio.

Now Im ok with with this purchase, but Fiio really needs to improve the quality of life of this product,.

@FiiO @FiiO Willson

You guys mentioned you may get an ambient mode through a firmware update.
Right now only the Shure TW adapters have it, but the level of transparency and customer service I’m seeing from you guys on this board is something I’d absolutely love to reward with a purchase. Already bought your FH5 IEMs.

Any plans still to bring that to the UTWS3 still or did that not work out? Are you still letting people into the private beta to try it out ?
Thanks guys great work here.

What IEM do you use with them?

I tested my CA solaris 2020 and they sound very good with these utws3 the only thing preventing me from getting my own is the connectivity issues. Until they get that ironed out, I am waiting for the utws5

 

[HipHopScribe]

How widespread are connectivity issues? I personally had zero issue, opened the box, fired them up and immediately paired them with my phone and they connect without fail every time I take them out. But I suppose a lot might depend on the sending device. My phone supports aptx tws+, which non-Android devices or even non-updated Android might not, so I imagine different scenarios might be more challenging

 

[frosty5689]

Mine worked fine out of the box using a OnePlus 7 Pro Android 10 as the source. The thing with Android and Bluetooth is it varies vastly between different phone manufacturers and even the same manufacturer. So it's hard for FiiO to do as a thorough of a testing as some big players like Sony can. It is also more likely for phone manufacturers to release fixes to their non-standard Bluetooth implementations if a Sony headphone doesn't work with it than a FiiO niche TWS adapter. I wouldn't attribute the connection issue to a problem on FiiO quality. The UTWS5 will have better connectivity on release than UTWS3 simply because the software is much more robust at handling the different quirks of different phones by then. Not because it is a better product. I imagine firmware updates will improve connectivity overtime but also agree that if you can't pair it you can't upgrade the firmware which means you're screwed unless you have another phone.
