I bought the cheapest possible earbuds and of course… what you pay for is what you get.
Bluetooth version: 5.0 Transmission distance: outdoor straight line distance 10-18 meters Battery capacity: polymer lithium battery 45 mAh Charging box battery capacity: 400 mAh Listening to music time: 1.5 - 2 hours Up Playing time: 2 hours Standby time: 100 hours Charging time: 1 - 2 hours Working current: 22 mA Standby current: 4 uA Price: $4.58
Surprisingly the specs match the reality and the only issues I found so far are:
- sometimes the WiFi connection doesn’t work when I use the buds
- at 30% the earbuds will automatically turn off
- in a call - the other person on the line will hear a strange buzz, but this doesn’t happen if you record and send a voice message
