The Bluetooth speaker connects easily and reliably, and remembers the connection for the next time you want to connect. I wasn't expecting much from the speaker, but again it is a solid speaker for the price and size, and I was surprised. The volume doesn't go too loud, but it is enough for a bedroom. At the highest volume there is no distortion in sound. I would say the sound quality is similar to what you get from a Google home mini if you are familiar with that. Definitely a very pleasant sounding speaker.
All controls are easy to use and intuitive. The remote control works as described.
I streamed some relaxing music and watched the light show, which made a for a very pleasant night.
I would highly recommend this projector if you are in the market for one. You can turn all the lights off and just use it as a Bluetooth speaker also which is very useful.
