This waterproof Bluetooth speaker has impressive sound quality and can get quite loud for such a small speaker. I have been using it mostly to listen to my talk shows on YouTube while I do dishes and other chores around the house. I also use it in the bathroom for music when taking a shower or bath. It is plenty loud enough to hear over running water, or even if I step into the next room I can still hear it.
It is easy to connect via Bluetooth. The on/off switch on the bottom is convenient to save the battery life and keeps my phone from connecting to the speaker when I don’t want it to connect. It has a button on the front you press to accept incoming calls. The outside of the speaker is a thick rubbery coating that grips nicely to surfaces and would probably give some protection if it was dropped. I have used it for over 4 hours now, and the battery still has not died. It also has a loop on it and comes with a clip so you can clip it on to your backpack or hang it from a hook.
