Using the app with the ULT Field 5. App is good & easy to use. I find the app's "Autostandy" & "Bluetooth Standby" modes not be what I was expecting. "Autostandy" turns the speaker off (including lights) after 15mins of non-operation. Even with "Bluetooth Standby" enabled, the speaker doesn't automatically wake if you start playing music on your phone which is odd. App and/or firmware need updating so the speaker goes into sleep mode (including lights off if on) & wakes when you play music.

I love my Sony headphones, but this app is quite buggy. I typically have two devices hooked up to the headphones at a time, and when I lock the mic/speakers to one of the devices, it will switch to the other one automatically if there is a notification and will not return to the one I "locked" the headphones to. It also won't let me switch back manually, as it says it cannot switch devices during a call, even though it just did. Very frustrating when a really good feature doesn't work at all!

Since the update, the Android app fails to launch when either my XM5s or CF100s connect. While the CF100s have limited functionality in the app, the dynamic ANC isn't working on the XM5s so what is the point of the app? I even have an Xperia 1V on the latest software. Also, the 'intelligent' switch off feature when you remove the headphones doesn't work without the app so it just wastes battery and sits playing music to itself if you don't stop Spotify! Fix this and the score will improve.
