Review on SLUB True Wireless Bluetooth Waterproof Sport HD Stereo Neckband Headphones With Mic 36H Play Time Sweatproof For Cell Phone Double Battery Earbuds For IPhone/Android (Black) by Amber Bennett

I rode them over rough terrain for the first time and didn't have to charge all the way which was really great. But I have had them for 5 months and this is no longer possible. They last 5-6 hours at best, and that's only if I let them charge for 24-72 hours, when I think they originally took 4 hours to fully charge. And if I don't let them charge, they'll die the next time I need them. The Bluetooth calling feature also turns off every time I receive a call. I also pressed the key combination at one point and the language changed forever. No problem, now I can say "Hello", "Goodbye", "Pairing" and "Battery low" in Mandarin Chinese. If the battery life list was more accurate about the lifespan of the earbuds, that would be very nice. However, this turned out to be the most annoying aspect of these headphones and they are not what I was looking for.
