wireless headphones.
Bought a pair of wireless headphones from Sennheiser by mistake and found this transmitter at a reasonable price with good reviews. I found it easy to set up and have had no trouble with it and was happy to be able to use my new headphones.

Would not connect to hearing aid
Probably a good product for headphones. But - it wouldn't pair with wife's hearing aids. Had to buy one from the hearing aid company which was made specifically for her brand. Not a big deal - just about the same price. Maybe return this one.

Is the analog cable an RCA style connector?
richard k on Jan 15, 2022
  Thanks for your question. The BT T100 comes with a 3.5mm audio cable that could be connected to a 3.5mm to RCA Y adapter to accommodate RCA analog audio output jacks.
will this also connect a AV receiver to wireless speakers?
A shopper on Oct 27, 2020
  Thanks for your inquiry. The BT T100 connects to a non Bluetooth receiver with a connection to an analog line output, allowing Bluetooth streaming to headphones or wireless speakers.
