I got these headphones to monitor my guitar sound for the rare occasions that I play through a sound-card interface into my computer, or to use them on a guitar amp when I am practicing home late at night and not wanting to disturb anyone. For those practical purposes (when professional monitoring or high quality sound is not needed), they are alright at this very low price.
They are also comfortable on the ears as the paddings are quite decent for such inexpensive headphones. The "hold" is a bit tight on the ears, but with a little counter stretching of the hard plastic on the top part of the headband carefully (without breaking it!) the pressure on the ears can be reduced.
The cable and the mini jack are also looking quite sturdy, and do not look likely to have defects any time soon. The cable is long enough to use with a device close by, but just short enough to not get in your way with a guitar at hand.
I tried these headphones also on a very nice stereo system with a "class A" amplifier and high quality CD player, using a jack adapter (not included) playing a couple of CD's with well defined musical sound, and that was just "okay", much like the sound of stringy headphones that come with smart phones. Plus they do let out quite a bit of sound at high volumes to the environment.
Basically, these are good enough headphones to use for practical purposes and simple applications, but if you are looking for a near professional sound you have to check the ones starting around low three digit prices, or spend at least about 35 euros or so on a Yamaha, Roland, Pioneer, Sony etc., for any kind of audio listening pleasure.
