CX 275 S is an in ear head phone which provides 3 ear buds of different size when used with right size feels good in your ear and and can be used for long time i used to have great strain in my ear when i use other head phones but cx 275 s is smooth and doesn’t feel like its in your ear.it has a good noise cancellation function which cancels all the outside world sounds.sound quality is at the best.
Its a gaming headset not the best for music, i used get each and every crisp sound but bass is not much good therefore its not much good for music but best for gaming and movie watching, it has also got a switch to answer and end calls which is good feature to have in a headphone.i would suggest it for anyone looking for a good quality headphone under 2000/-
