There is no button to turn it completely off. The batteries started going dead and an high pitch beep goes off with no way to stop it. I had to bury it in blankets in my garage. Also, it is always dead and the charging port is rusty only in a couple weeks. Not very waterproof.

I purchased two barnacles that are amazing. One is on my golf bag and one is on our beach cart. Amazing sound quality for such a little device. Love it.

Barnacle Pro, excellent little speakers. Part missing from one box, customer support was excellent. Will DEFINITELY by another set(s)

Great highly portable compact waterproof speaker. I suction cup this in my shower to listen to music and play podcasts while I clean or take a bath and I also take it to the river with me when I kayak. It’s great. Highly recommend.

Purchased Barnacle Pro to use on my efoil. Suctioned it to the top of my board with no problems. Suction is excellent! Probably going to buy either the Vibe or X next as I want a little more sound.
