He also works at the same facility. My childhood walkie-talkies sent the signal better than Bluetooth does. Very comfortable I hardly notice I have it in my hear. The color is darker than expected though. However, I was disappointed that the outlet adapter forces me to face all of my angled plugs toward the adapters wall plug. You can save a bunch of these to the device itself and have them play in a loop. Great price for a great product! I was very impressed with how solid they are and how they grip the floor. Das hatte jedoch massive Schwierigkeiten, eine Bluetooth Verbindung zu meinem Smartphone aufzubauen. I bought this speaker about six months ago and when I got it, I thought it sounded decent.
