Which brings us right the sound would be:
Better than expected. I hear sounds and noises that I have so far in TV (did I already tried) did not notice. Toll. For a cinema surround system, the hi-light headphones do not come natural. But that was not the purpose of why I bought it.
For my use those things are great:
+ Very light and space saving (must be transported in the aircraft luggage yes, because every gram counts)
+ Adjustable (but they are enough for me straight!)
+ Long cable
+ No pressure on the ears - I could at the first rehearsal wear more than two hours with glasses, and had afterwards neither ears, nor expressed the strap of my glasses!
+ Adjustable volume on the cable
CONCLUSION:
Everything fits. Music lovers will probably turn up their noses because they expected a portable sound system in the ears. I have absolutely with the playback quality is no problem. On the contrary, I hear sounds that I have otherwise only perceived from my good stereo - if I listened very carefully.
