I have tried all the troubleshooting steps counteless times already and I can confirm Bose 700 headphones has backward compatibility issues with older bluetooth versions:
- When I connect them to my laptop (Windows 10) via Bluetooth(ver 4.x) , it says Laptop name Lost every now and then. This happens even if the only device connected is laptop. It has nothing to do with 2 devices connected at the same time.
- I tried a bluetooth transmitter Avantree Priva III which is also 4.x , it keeps saying device name Lost so frequently even though there is nothing in between headphone and the device
- I switched to RHA Bluetooth Adapter which is ver 5 and it never looses the connection
- It has never lost connection to iPhone x which is on Bluetooth version 5 as well.
Even though I love these headphones, its quite frustrating that it cant keep the connection with the laptop for continous skype for business calls.
