BTunes Flight Adapter Bluetooth 5.0 Transmitter Makes Headphone Jack Output Wireless, to 2 Sets of Headphones/receivers simultaneously, Share Music/Movies.

Inspired by traditional flight adapter and BTunes to make headphones wireless, we release a Bluetooth 5.0 transmitter to make any headphone jack (where you normally plug in a set of headphones) wireless.
It's simple to use, easy to store in a headphones case. It's employed with the industry leading low latency codecs aptX LL and packed with a big battery up to 14 hours streaming of audio from your favorite sources, either your home entertainment center or your in-flight entertainment center.

We designed it for ease of use, one-thumb operation. Take it out from the storage space, your right thumb is naturally rested on the button, press it to turn it on; and then plug it in a headphone jack. When you are done, pick it off from the headphone jack, your thumb is naturally on the button, press to turn it off and then put it back into the storage space in the carrying case.

It's a great companion with all BTunes receivers, such as Bose QC25, Bose QC15. You can share one streaming with 2 sets of Bluetooth headphones or receivers.
