Review on Wireless Bluetooth 5.0 Headphones: 20 Hours Playtime Earbuds with Charging Case - Stereo Earphone Cordless 🎧 Sport Headsets in-Ear Earphones with Built-in Mic for Smart Phones - Ideal for Work, Running, Travel, Gym by Julie Henderson

i like these headphones good self charging device. You can just plug them in and listen to music or talk very well. ear, but I have three problems with them. 1 can't change Chinese, but by reading the manual, you can set yourself up well. 2 - It only takes 1 hour 30 minutes to charge the mines before the Chinese warning starts to warn. I think they are closing, the battery is low or dead. 3 - Also the volume function is confusing and sometimes hang up the call or pause the music. Since the controls don't work properly, only tapping to end the call or pause the music works. I can not return because I throw away the instructions and the small box it came in, but I plan to buy a more expensive one, the only thing I like is that they are very comfortable to wear on the ear. For me the main issue is that the battery life is only 1 hour 30 minutes before it shuts down. So be careful
