Sennheiser BTD 700 Bluetooth USB Adapter

This is a Sennheiser Bluetooth adapter.
The firmware has been updated.
I primarily used it connected to a stationary Windows PC.
I have not used it for external purposes, such as connecting it to a smartphone.
I am selling it because I do not have any aptX-compatible wireless earphones on hand.

Thank you for your consideration.

High-quality audio compatible Bluetooth USB adapter.
