- The range is the area of application (calls when the device while in case) accordingly in order.
- The headset can be worn on the right and the left, this is easy to turn part of the "in-ear".
- A few hours Ingress / music / navigation on the bike on the road keeps it through easily.
- Voice quality is fine.
The only negative things that I noticed were:
- The keys are a little stiff, you should use the headset with a finger already fix well the keys to press clean.
- The silicone used for the ear is a little hard, here I've been more comfortable variants carried by headphones.
All in all, but still highly recommendable in the scope of supply. Price / performance ratio.
