I've had Serengeti glasses before and wanted the same quality again. Since I use them for flying, I want to avoivd polarzing glasses (problems with some displays). The serengeti wire flex performs very well and it does not interfere with the noise protection the headset must provide - even with the glasses on, the headset (LS Zulu) fits well without any gaps caused by the frame.
Pros: Great optical quality, good fit
Cons: The case is rather bulky - most pockets will bulge
