Look first of all they are wireless which is so convinient to use.
But the sound quality if heard under the right soundtrack.nothing can beat it
Though sometimes there is a glitch when connected to any device.
They fit right into place and are best suited during sports as they have a rubber coating and hence are not damaged!
However the problems faced are their battery backup is not good enough.
They are very expensive and compared to that they are not that efficient as they should be.
I wont suggest you guys buying this if you have a budget problem!
