+ It is pleasantly light, yet retaining a stable
+ Both the running and on the road bike (with helmet) it has a good fit and stays in place - one forgets quickly that you are wearing them at all
+ Despite my long but narrow head it works not too wide - the problem I have otherwise had already
+ The glass switch works with a little practice well - thanks to the enclosed microfiber pouch also fingerprint-free possible
- The only drawback is the in my opinion unnecessary lettering on the bottom right - he irritated easily, but you get used to it
Overall, a strong buy recommendation!
