- The volume control works in a loop, ie on the two volume keys can provide direction louder or quieter. Once you get too much press when setting the minimum / maximum volume, coming after minimal or maximum immediately after a maximum immediately minimal. The former can already twirl in the ear.
- You can not ask silently during the call ringtone. It will be played when calling the Cell and a headset ringtone. The latter does not respond to the mute on the phone.
- The application is initially a bit fiddly. If you have more practice, it is relatively easy.
Conclusion:
The negative points fall not really significant, so definitely recommended. Very good value for money.
