In addition to solid sound quality and impressive Bluetooth range, the standout feature here is the SoundCore's 24 hour battery life. I've owned one for over a year now, and while I'll occasionally remember to plug it in when I pass by a spare microUSB cord, it's never once given me a low battery warning, and I use it a lot.
The writer forgets to charge the speaker many times and it still never loses charge.
