For a bluetooth headset sports, I have not found better and I've tried several. One of my former and elsewhere Plantronics Backbeat 903+ also that made the soul after many years of good service. I must say that this new version of Backbeat is much better. Lighter while maintaining good performance and access to buttons / functions. The holding is better than the old BackBeat 903+, whether for racing or keystrokes to bags. I had a Philips holding a roughly during the race but impossible during the strikes on bags, so I gave up. Autonomy is also retained (~ 7h) for those like me who sentraînent ~ 5 times / week that is not negligible. The cover is not bad but too small for my phone so I gave my older son.
To Sum Up: Long battery life, good performance, good sound (but allows you to hear surrounding sounds), convenient button.
