Great Bluetooth headphone set
These headphones are very comfortable and the sound quality is great. I use these to aid with guided individual and group meditations and they create a great container for getting deep into music or meditative instruction. I would love to pair my JBL Bluetooth speaker with them at the same time to have room sound when the headphones come off but have yet to be successful in pairing that device with the transmitter without a disconnect to the headsets. I have only had these for a month so I am still finding my way. Set up tutorial videos are available but I have found them more flashy and less informational than they could be. In the end this is a great product…

Avantree
Dear Sunrise We’re honored to know that you’re happy with our Avantree products. To answer your concern, please read the following question. Can I pair another Bluetooth speaker to the transmitter? No, the Avantree Flex Base transmitter does not support pairing with Bluetooth speakers. While it offers three audio input modes (Phone, OPT, and AUX), in Phone mode, it is designed to connect with audio source devices (such as Bluetooth-enabled phones, tablets, computers, or TVs) rather than audio output devices like Bluetooth speakers, headphones, or soundbars.
