XIAOMI Mi Bluetooth Speaker 16W Black

You get your standard play/pause and the volume keys, along with a dedicated power key, 

 pairing mode key, and a regular Bluetooth pairing key. There’s also a microphone, which comes in handy if you take calls on your speaker. A lanyard cable is attached to one of the ends and that surely helps while carrying it around, or tying it to hook.

Xiaomi says the speaker is IPX7 certified, which means it can survive pool parties as well as rains. The black colour variant that I have is stealthy but those seeking a flashy option could consider the blue colour variant. I wish Xiaomi had included some LED strips or tiny strobe lights on the Mi Portable Bluetooth Speaker 16W to help disburse a party mood
