I'm trying to achieve two goals.
- Use my headset without plugging it into my phone
- configure smart lock with the bluetooth so my cell phone stays unlocked while in my home office.
Currently I have a Sennheiser SD Pro 2 with an adapter cable plugged into the "phone" port on the base station that converts to a 3.5mm TRRS connector that I plug into my Galaxy S10. This allows me to use the Sennheiser headset for phone calls on my phone.
I'm looking for a Bluetooth device that I can connect to the TRRS jack and then pair with my phone so that I can use the Sennheiser headset in the same way that I do now. The Bluetooth device and phone would remain on my desk, but I would be able to move around my house with the headset.
All of the products I've found are for transmit OR receive, or have a built in mic and only send audio.
Can anyone provide a link to a product that I can currently buy or detailed instructions on how I might combine a few parts?
I don't mind soldering.
