Portable Wireless Bluetooth Speaker,BOOMER VIVI Mini Small Metal Pocket-Sized Music Sound Box Hands-Free,Rich Bass,HD Audio,Built-in-Mic for Phone,Computer,Outdoor,Home. (Black)

it is a small speaker as you can see from one of my photos. I have put my watch and speak side by side to get the scale idea. However, it does produce pretty loud sound. for the size, it isn't bad.But in a way, it is useless because after you link the bluetooth to your phone, and if you want to connect again, it does not connect. basically you have to unpair it from your phone and do the process again by pairing them again if you want the speaker to work. Bottom line is that this speaker does not reconnect automatically to the last connected device. Which means it is an useless bluetooth speaker as it is.

Small and exquisite for taking.

For the price you can't beat it sound quality is good battery life is good very pleased
