WiiM Pro Plus Bluetooth connection with Sony headphone

[SDRnerd]

My Wiim Pro Plus looses Bluetooth connection with a Sony WH-CH720N headphone frequently. If it sometimes connects back, the sound is stuttering, and I have to power off the headphone and power it back on. I'm sitting only 3 meters from the Wiim without anything blocking the direct path between both apparatus. No other Bluetooth devices are active in the vicinity.

Any toughts...

Have you tried the setting suggested in the first point here? https://helpguide.sony.net/mdr/2966/v1/en/contents/TP1000777012.html

Yes, I have read this page before and still no luck getting rid of the culprit. The headphone has worked OK for 3 weeks before the interruptions started. Nothing has changed, and no devices have changed place. Last week I could even listen up to 20 meters remote from the WiiM outside the house. Strange things indeed... Maybe updates changed things???

Have you tried rebooting and re-pairing all of each device?

Yes, this I did eventually, when the problem persisted.

Although you may not have changed anything one of your neighbours could have done so and this may have had a knock-on impact.
Bluetooth and wifi can interfere with each other as Bluetooth uses the 2.4 Ghz band.
Are you using a wireless or wired network connection for your Wiim ? If the former try configuring the Wiim to use "5 ghz only".
You can also try changing the network channel your wifi uses on your router . This may help prevent interference
