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

Best regards

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.

@FiiO

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