(Open Box) JBL Go 4 - Ultra-Portable Bluetooth Speaker - Blue

This little speaker is a gem. I found out the hard way that it is not a good idea to listen to your vehicle's Bluetooth sound system without the engine running which is something I do often.... Park in a pleasant spot and listen to music or podcasts connected through my phone's Bluetooth connection. This practice eventually resulted in an early and complete death of my vehicle's battery. (-Luckily it was still under warranty.) So I got the car battery replaced and immediately went online to Walmart and found the JBL Go 4. The sound is quite good for a speaker this size and, unlike some reviews, I've found the battery life to be quite good.... easily 12 hours at a moderate volume. At moderate volume there is no distortion either. That said, I can't speak to the battery's performance with the volume cranked up to maximum. It's also advertised to be waterproof which I can't comment on either as I've never used it in a 'wet' environment but I trust JBL's claim in this regard. This is a great little speaker, if a bit costlier than other, similarly sized speakers. And the JBL brand has a solid history and reputation. I have run into a glitch with the downloadable app, but only a couple of times. And the app does allow one to adjust the sound quality and even offers an equalizer mode to customize the sound quality. I highly recommend this little Bluetooth speaker.
