Works ok on my phone, but not the Walkman headphone app. It sees them but when I try and connect it goes back o the add device screen.

Try in a location away from other BT devices. Shut off the BT on your phone, and away from any other devices. Sometimes other BT signals can confuse the signal, and/or another device that it was paired with before may pre-empt the connection from the ZX700.
Then:
1. Put the XM5 into pairing mode, and connect from the Headphone App
2. Still fails, reset/wipe the XM5, and try step 1 again.

After the above, I can't think of much else to try.....

As the owner of 20 different DAPs I'm very impressed by the Zx707 the uncapped version from Japan is plenty powerful enough for all my iems. The sound signature in Direct mode is just intoxicating the battery life is exemplary lasting for many listening sessions putting all my DAPs apart from the NW-M1A to shame. The fact that doesn't even get warm while being used on high gain for 6 hours at a time is just class leading. All in all an instant hit.
