Review on 🔊 inOpera X1 Wireless Bluetooth Speaker for Outdoor Use - Waterproof Portable Stereo Speaker with HD Audio and Enhanced Bass, Built-in Mic IPX6, 4.2 Handsfree Calling, TF Card Slot (Black) by Laura Patzner

I bought this speaker and ended up using it in my old (very noisy) diesel truck. Was very surprised by the excellent sound quality and basic response even at the volume required to be heard over truck noise! I haven't really tested the battery life since it's connected to the charger - the only minor downside is that it's a little clumsy to find the black-on-black power logo and press it for the 2-3 seconds the time it takes to turn the device on or off.
