Review i7s TWS bluetooth earbuds

October 05, 2020 | Reviews

I bought the cheapest possible earbuds and of course… what you pay for is what you get.

Specifications:

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 i7s TWS bluetooth earbuds
