Review on 📶 Friencity Bluetooth 5.0 Transmitter for TV & PC, Low Latency Wireless 3.5mm Aux Adapter for Home Stereo, Radio & Projector - Connect Two Headphones Simultaneously (apt-X, DVD, Xbox, PS4, RCA Compatible) by Ronnie Staver

I bought this to connect two bluetooth lights and speakers to my phone and play them together wirelessly. It took a few minutes to connect both speakers to the adapter, but then everything worked great! Used a few times, no repair needed, they keep in touch. It's very small, about the size of an Oreo cookie or smaller, and the battery life is great. I have yet to charge it after listening to it twice for 3-2 hours in a row. I would recommend this if you want to connect a pair of Bluetooth speakers at the same time.
