I just recently bought it less than a month ago and after trying it a few times, I must say, I'm happy and completely satisfied with my purchase.

Awesome!

Can I plug this into my headphone jack on my stereo to transmit my CD's to my new Bose headphones?
Asked by: Buck
No, the Bose S1 Pro+ Wireless Instrument Transmitter (1/4") is designed specifically to connect instruments (like guitars or keyboards) to the Bose S1 Pro+ PA system, not to transmit audio from a stereo headphone jack to Bose headphones.

Asked by: Mark
Yes, you can plug the S1 Pro+ Wireless Instrument Transmitter (1/4") into the output of your Bose 4‐channel mixer or any instrument/gear with a standard 1/4" jack. It’s designed to work seamlessly with instruments and line‐level outputs, and once connected it will pair wirelessly with the S1 Pro+ system for cable‐free use.
