I can't select LDAC in the Bluetooth settings, got two sets on Sony headphones. It has updated to the latest firmware, still it defaults to AAC. Most of the audio settings can't be switched on - I get HD Audio and the AVRCP settings, nothing else.

Stupid question: did you actually turn HD Audio "on"?
The LDAC option will be greyed out if HD Audio is off...

Yes, on and off several times.

Yes, on and off several times.

I think I had a stubborn HP where the LDAC option only showed up on the M300 after an initial "connection / play something / disconnect / reconnect" cycle...

Hey found out what it was - When you have 'connect to two devices' on in the Sony Connect App, if stops the LDAC. Switch that off and you get LDAC.

Thanks to Reddit. Have to cancel my return now.

LDAC is working.
What Bluetooth devices are causing problems?

Sony headphones, have to switch off 'connect 2 devices' in their app, otherwise it defaults to AAC. Silly problem, not sure if the manual says anything about that.

Why are you canceling the return? If you had already concluded it was the M300's fault and you were unhappy enough to return it, how is it going to be different when you hit the next (unavoidable!) snag?

The M300 works fine, It's Sony and their choice to disable LDAC when you have two devices connected, something about bluetooth bandwith. I streamed to my NAIN Uniti atom, and got another Codec working. So it your device support a Codec it works fine.

I know streaming bluetooth from a budget DAP to an Atom Headphone Edition is silly but just wanted to get everything connected.

Wow, I can not believe this. I only just got this M300 and I found the backside just having fallen off entirely. It lifted it up this morning and it was loose, upon better inspection it just fell off entirely. The battery these last 2 charges disappeared in hours when I did not even use it, it was just laying down on my desk, screen off, nothing playing. I was already a bit suspicious when the battery went out that quickly because it wasn't even being used.

And how on earth is my entire serial code not even visible on the back? I am so shocked I don't even know where to start.

Edit:

I've now factory reset my device, used my moms M300 and put them aside. While mine drained 20%, hers only lost 5%. The battery is a complete mess on this device.
I still dont know how the back came off.
