Review on 🔊 Outdoor Technology OT2800-B Turtle Shell 3.0 - Rugged Waterproof True Wireless Bluetooth Hi-Fi Speaker, Black, One Size - Unleash High-Quality Audio Outdoors! by Will Ridpath

I bought two of these to assemble and put on my motorcycle so I can enjoy long rides listening to classic rock music. They paired easily, but I've never heard any of the sound effects that the manual says should occur. As soon as I turned onto Highway to Hell, my living room blew up and my wife ran away. It was a good test even though they were brand new, but one of them doesn't hold a charge after a year of use and shuts off after about 2 minutes of play. This system is a good idea, but it needs more volume and reliability. UPDATE: They sound great while cruising around town at low speed, but once my bike hits 60km/h I can't hear the music. Loud but not loud enough for a good ride. Also, these speakers don't like the strong shaking that occurs on bad roads. During that time they shut down a lot. I will keep them at home for my wife but for my bike I will buy a better working and noisier system.
