I have used many headset to name a few would be jbl t250, jbl t450, sennheiser hd 200, sennheiser hd 202, logitech h108 and few more. These were the best as per its bass. And ofcourse they deliver the extra bass. Overall build quality is good. Wire is also good. Comes with 30mm neodium drivers.Cons-Even if they are good for listening to music they aren’t really good for gaming.-Definetely not portable.-Wire length is not big enough.-Only the AP version has mic.-Earpads not replacable ( though they are good enough i.e. they won’t wear out or tear away easily.Alternatives to this headphone-Sennheiser hd 202 ( doesn’t have very good bass but do perform quiet well incase of music where bass doesn’t matter) .-Steelseries flux luxury edition ( haven’t really used these yet but I am planning on buying them as they are portable, comes with lots of accessories which become quiet convinient in long run, 40mm drivers, comes with mic) .
