Very good helmet, comfortable, good record audio.

My Sennheiser HD280 has passed away, I shopped his replacement. I turned, after careful consideration and without ever having listened in store, to the AKG K712 pro, for several reasons: it is one of the few headsets still be manufactured in Europe (AKG no longer manufactures this model on the old continent, the rest is made in China), it is best noted in its category (open helmet) and stayed within my budget (the top of top of my budget for audi helmet (motorcycle, it is still more expensive :-)).

Most of this helmet: a very good record audio, loyal and neutral in restitution songs (attention to the quality of your source, a bad MP3 frustera you can, like music online medium quality).
According to critics and other experts audiophile headphones have been improved in the low frequencies; I can not confirm or deny, but compared to my old HD280, I find him the same quality (or other default) it does not present too low. Amateurs low, it will be necessary to make a one button on your amp (but as I get older, my ear will never be yours). The detail on jazz pieces is remarkable in live scenes I think they lack a bit of depth, compared to my audio speakers ("old 'Cabasse).

As for listening comfort, well pads fit on the ear, they isolate themselves from the outside world enough without you cut, and in winter you include a soft warm feeling. In summer, after two hours, a pause is needed freshness. The maintenance is very good, felt no discomfort whatsoever on the top of the head or ears. No bad compression sensation. In short, very comfortable helmet.

Last asset, the cord of the headphones can be unscrewed, and it comes with an adapter screw jack too. So if your cat is like mine fan cords and he spends his time boulotter them, do not panic, your beautiful headphones AKG always work, you just need to buy the cord.

In summary, if you have the budget, do not hesitate.
