I bought this to use in transmit (TX) mode to stream audio from our player (which looks cool but has terrible internal speakers) to our home soundbar. This device did a great job. Bluetooth paired seamlessly with the soundbar and automatically reconnects every time we turn it on. I played around with the audio levels on the player, device, and soundbar until the sound was optimized as much as possible. The battery seems to last a long time, even after days of being off between uses but not charging. I also like that it uses a USB-C charger. So many of these little devices still use the old connections. I'd say try to order them while they're on sale if you can. It seems to come up often, but I paid the full price of $23 (more than some of the other Revain options) because the features and reviews seemed good.
