Sony xb-250 is a quality product. I bought it two months back and it’s working fine. The extra bass from the headset gives the desired effect for songs. Usually the frequency range will 20Hz -20kHz in most of the headsets. But in this the minimum frequency is 5 Hz. Less is the minimum frequency, better the sound clarity. I’ve seen many products of the same price, but nothing has the specifications like extra bass, sound clarity.
The design is lucid, to say, not a stylish one. But when u put this for more than an hour ur eat Starts aching. This is the Basic model in XB series which I got it for Rs.1100 in Amazon and if u buy upgraded versions of this, u may find it comfortable. After certain usage period the head spacing between the two speakers become more, this is usually the common problem in most headphones when the design and material of the equipment is not upto the mark. And also it comes without a mic, can only serve u the purpose of listening to music. Overall the headphones are good
