Sennheiser HD250BT turn off after 30 mins?


Novice Member

Looking for help here please.

I've recently purchased Sennheiser HD 250 BT headphones which are brilliant but whatever I'm watching, be it Netflix, YouTube etc. they turn off after what seems approx 30 mins?

I appreciate they're probably entering a standby mode but I have no idea how to turn this off and the instructions are useless?

Any guidance greatly appreciated.

Many thanks

I downloaded and had a read through the user manual and there's no mention of any standby mode.
Did you fully charge the battery when you first got them as detailed in the manual?
Are there any voice prompts before they turn off?
Have you tried them with a different Bluetooth device?
