Concerning the product, being accustomed to wired headsets entry (Koss Spark Plug), seems to me the good audio quality. The range is excellent, I live in a duplex of 40m² and I capture everywhere, and to the door of the building (I am the first floor).
Easy to connect to devices, the manual is very well done, just follow the signs
=> HTC Desire: Just turn on the headset and put the phone together
=> HP Touchpad: Same
=> In xubuntu Laptop: A package to download to add a bluetooth module pulseaudio, a reboot and an association like the two devices above and AC drives, but you must know ... Music and chat on skype work (quality micro very good way)
=> PS3: Easy Association (Device Settings / Bluetooth Devices, also think about going to the Audio Device Settings to turn on the headset input and output device and the sound settings to allow multiple audio outputs). Tested on Modern Warfare 3, the sound of the game goes on TV, only the voices of others are in the helmet, suddenly the semi open side of the helmet is very convenient to be able to hear both without putting the TV in background. Hard to say if the microphone worked in this context but a priori is the case.
The helmet hold very well on the head and does not seem ready to fall. I have not yet tested in sporting terms, I'll let you know.
Warning against by comfort. I have a rather large head, and the headset serves me at the ears and the skull to see if the use ca fade with helmet softens (first encouraging signs on that side, to be confirmed) ... If the tips are varied, generally all right for me, so it should be feasible to find the Shoe Fits for everyone
Not with my glasses, except by asking the following branches of those on the hook which is positioned on the ear (not very nice)!
Cap ok.
