Description:
The S921 has CVC 6.0 noise cancellation and magnetic earbuds, but with a 60mAh battery (The average battery power for Bluetooth headsets is 120mAh), it is no surprise that the usage specs (5-hour talk time and 180-hour stand-by) of this model fail to keep up with those of most other models, as well.
Also known as Esonstyle S-921.
