I like: - NFC recognition for always easier recognition (it must be on an NFC smartphone) - Bluetooth connection to the compatible device - The quality of headsets is so good that I slept with video or listening to music - Autonomy is about 6 hours of continuous use - Recharges in less than one hour to see next device used - The clip is solid
I hate: - I will perhaps take a white or black model, but it's me who is selected blue so good
One thing to add, if you ask a bluetooth A2DP key on your PC you can use this kit on your PC such as with Skype. This is what I do and finally I used more for that than for my smartphone.
