The headset is (with enabled effects processor), the sound is absolutely best I've heard, the noise reduction is also excellent and adjustable. Both, however, applies precisely only with activated and configured effect processor. Without or in power-saving airplane mode I found the headphones not very good, on the contrary rather less than mediocre. My main counterargument is clearly perceptible delay the sound via Bluetooth and via cable (when the effect processor), at Parrot known and reputed in Bluetooth 180ms and at Line 60ms (I could not detect any differences between the two, suppose that both are close to 180ms ). For musicians, gamers or movie junkies this latency in my opinion is intolerable, useless for my main purpose electric piano and guitar. The design is certainly a matter of opinion, but the valent-feeling device fitted well on my supposedly quite thick head, the ears were completely enclosed by the leatherette cushions (so that here already outstanding noise reduction performed), the adjustment of the headband succeeded without much difficulty and remained obtained with stronger pull. The headphones felt slightly, I have not noticed a disturbing even when wearing long. The controller with built-in touchpad is a matter of taste, I found practically, even if the unit repeatedly recognized break rather than another desired gesture. Automatic switching off the sound transmission when removing the ear pads I found practically, it sparked in my rarely from faulty and worked even while lying well. The app for Android running on Samsung with Android 4.2 without error, the above functions were all authorized individually switched on and off, so that for example the automatic shutdown or noise suppression could be easily disabled. In other devices paired or used the phone function I have not. Software updates can easily access both via USB and via APP. My second major counter-argument: After longer breaks (> 2 seconds about) on the line input tones or missing parts before the machine again began playing. Moreover, a very brief Bluetooth playback switched after update to 2.05 at Line cable simultaneously connected repeatedly intervening and generated a slight sinus-like sound in the background, sometimes even a very short distance of the current music playlist via Bluetooth intervened. Conclusion: (must ja 2.5 hours after load) without the only 6-7 hours holding the headset battery is below average. With activated effects it's great suitable for listening to music via Bluetooth, perhaps on Line. Making music is with the device almost not reasonably possible, any more games or watching videos (for people who pay attention to the synchronization).
