Cx 275s is best headphone under rs. 2000/-, its sound quality is awesome, I ever feel, if u want 2 feel bass and your budget is below 2k then go for it, beause no any headphone can give bass quality like this, and cx 275s is looks good and sleeves are very good which feel comfortable for long time listeners, its bass is steel same in low volume as higher volume and your ears doesnot gona pain, my friends is using this headphone since 1 year and till now no any problem faced by him, yesterday I also ordered this headphone, it maintains bass and treble in lower volume as higher volume.
