Bluetooth transmitter for Sony WH-CH710N headphones?

[ethicsgirl]

Hello,

Please can anyone suggest or recommend a bluetooth transmitter with 3.5mm audio connection that would be compatible with Sony WH-CH710N headphones? (Spec details here: https://www.sony.co.uk/electronics/headband-headphones/wh-ch710n/specifications

I ordered this bluetooth 5.0 transmitter/receiver - it works with my earphones but not my Sony headphones:

Any suggestions gratefully received. Thank you.

hey ethicsgirl , I might not be able to help you with this one, but why I know that a transmitter isn't always guaranteed to work.
