Its design allows you to listen to your music player or smartphone without being isolated from the outside world is an asset for me for my sessions outdoors.
The helmet is not easy to put on the ears and requires a certain habit, but once placed the helmet is perfectly maintained, even on a session of 80 minutes running no particular discomfort is felt only ... Excellent!
The cord is flat type is a bit confusing at first but devilishly effective storage term, never tangled cords. The headset comes with an extension that does not suffer any particular defect, the cord and the golden fittings are of very good quality.
The integrated remote control at the microphone a latest generation smartphone, the integrated volume control cable seemed a gimmick, in reality it is not so it eliminates the need to remove an ear in order to hear something or handle the player or smartphone, it's really a good idea.
The sound quality is good to be a little diffuse by design headset is imprecise: the sound is less accurate than Kitsound Enduro (in-ear) I also have, however outdoors if the wind is now the listening does not provide any particular hinders listener are not affected it is the first time I meet it on a helmet in congratulations Jabra.
To: quality of materials, comfort, sound quality (standard headphones), the high quality pouch to put his headphones it, the extension, the hands-free kit, volume control, flat seams.
Against: the lack of precision, a little expensive.
Conclusion: even if it lacks precision Jabra headset is a powerful, comfortable for sports use, held perfectly in place once it is the best helmet for the moment that I found for sporting use shame it is a little expensive.
