FiiO Control app should be 1.1.4 – once you have the updated app you can download the .bin firmware file that @FiiO provided above and manually update your UTWS5 to this beta firmware.

In my limited experience, it seems when I hit pause that ambient mode gets muted for half a second and then returns. I haven’t timed it to see how long I can use it while paused, but I imagine it’s set by the “timeout” option? E.g., 5 minutes, 30 minutes, etc. “Game mode” feels slightly more...

If you’re on Android you can already request the beta firmware from @FiiO – I requested the beta firmware but I couldn’t actually control the new features with my iPhone until this update.

Ambient mode now accessible for iOS! I just confirmed that the new FiiO Control app that was released yesterday supports control for “Game Mode” and “Ambient sound” on the UTWS5. Ambient mode is surprisingly sensitive if I crank the volume.

FWIW, I had the same problem when I first paired through Settings in iOS. Once I unpaired and used the app to initiate pairing (like you describe) I was able to use the app consistently. Sorry to hear it’s not working for you! Just a thought… what if you deleted the UTWS5 from your iOS...

Based on a web search it looks like you’d want the MMCX version. As far as how well they’ll drive your Campfire Andromedas, I don’t think you’ll have a problem with power; at 13 ohms, they have a lower impedance than my JH16s (18 ohms) which, to me, have ample output at a low volume. General...

I received my UTWS5 units yesterday and paired them with my iPhone. Excellent experience so far! The 2-pin version fit my old JH16s perfectly. Hope to find a way of testing the more advanced Bluetooth codecs (maybe with a Bluetooth adapter on a PC?), but the AAC of iOS sounds surprisingly good...
