Review on 🎧 2-in-1 Bluetooth Headphones Speaker, Doltech Neckband Wireless Bluetooth 4.1 Headset with Retractable Earbuds, True 3D Stereo Sound, Sweatproof, Call Vibrate Alert, Built-in Mic - Rose Gold by Laura Thompson

Everything went great. but it is not waterproof or waterproof as advertised. I usually buy waterproof/rugged headphones because I sweat a lot when I run, but this pair got a few drops of sweat on the speakers and they vibrated wildly. That day I stopped my run and let it vibrate overnight. I installed them the next day with no problems, except the language changed from English to Chinese or Japanese, I'm not sure, so the product somehow restarted. I didn't mind changing the language, then left. and a little more sweat got into the speakers and did exactly the same thing as before, only it wouldn't stop. I tried to keep it going by leaving it charging when not in use, but then the button slider to switch from headphones to speakers stopped working and the speakers made a crackling noise like they were trying to play music . I ended up letting it die again before charging it again and now neither the on/off slider nor the headphone/speaker slider worked and it stopped working. All of this happened within 7 days.
