My Sennheiser HD 350 GT simply cuts off after 60 minutes. Very annoying. After a 60 min zoom meeting the device goes into: Power off and I am disconnected and have to connect again

Can they pair with linux machines? I have a hd 350bt headphones but they, though visible for the linux machine, can't connect. They work properly with an android device. I even tried pairing them with a linux pc that successfully connects with a different pair of bluetooth headphones but still couldn't get them connected. Are there any specific drivers that I need to install or are these headphones just not supposed to work with linux? Thanks in advance.

is this compatible with a LG TV or just phones?

Peter Webster • 24-11-2020

I have purchased HD 350BT headphones and transmitter. Despite best efforts, multiple audio competent assistants, the headphones will not function. We have paired them to another device ( mobile phone ) and the headphones worked fine. However when linking the headphones to the Sennheiser audio transmitter, the headphones pair but there is no sound. We have done every cross test we can do. Our deduction is there is a problem with the transmitter. Please replace the transmitter. I will arrange to return the existing item to you. Please advise what you would like me to do. My phone is 0407245170. My wife is hearing impaired and this item is essential to operate. Many thanks
