Isolating headset with good bass but uncomfortable

A sober helmet of the famous Austrian brand. Billed as the K619 DJ headphones none the less nomadic. Comes with a small carrying case and an extension cord, it can slip easily into a purse or briefcase (not too small either).
As for its audio profile headphones have a pronounced tendency for bass. The sound remains clear despite mids and highs frequencies left a little aside. It will suit a more electronic style of music. It is well insulated and saccommodera a public transit use.
Unfortunately, the K619 soon uncomfortable ... After a few minutes, we compress the helmet. In addition, its weight (215g) is also felt. It has a remote / integrated microphone, but again, the function reaches its limits when you want to use it with an iPod, for example, the remote control does not respond.
Finally, the K619 when my purchase, priced at 35, was a good price / quality ratio. The rate has increased rapidly, I would advise other two headsets: the Y50 AKG, DJ headphones for those who love the bass. And, if you want better sound friendly but clearer, I highly recommend the AKG Y40.
