SOLUTION: negative

PROBLEM: Overview: The speaker is very well built and portable. The build is excellent, made out of very strong plastic. The speaker has good insulation from dust and water, providing some needed features that other high end speakers don't have. Build: In my testing the speaker held out really well. I took it to camp to test out the durability. This speaker held out really well. The front amps get very loud when paired by Bluetooth. In my case I used an iPhone XS. In my case i used the speaker while I was outside By the campfire. Battery: I tested the battery nonstop and noticed that I got easily 6-8 hours on constant use. In my defense my phone didn't last as long thus battery life is very subjective to the loudness and if Bluetooth is use. I mostly connected the device via Bluetooth. Features: The main features that this speaker has are the micro sd card slot, and microphone built in. I used the speaker for offline use by transmitting music via bluetooth. Because I was camping the service in my area was fairly poor, thus just adding my whole music library to the micro sd or usb is very convenient.

SOLUTION:
positive
