Utilizing Bluetooth EDR 2.1 technology, this ECOXGEAR ECOXBT GDI-EGBT500 speaker lets you listen to music stored on compatible Bluetooth-enabled devices from up to 32.8' away. The waterproof design guards the speaker against moisture damage.
The speaker sounds great and is waterproof. I use it in my hot tub with the kids and they take it in and out of the tub at least twenty times every time we use the hot tub which is about Two to three times a week. It's nice not to have to worry about it.
