I need a new headphones and i want it cause i want a good bass effect. The Bass effect should not crack or the quality of sound must not downgrade. Which of these three headphones would you suggest? Sennheiser RS 120, RS 130 or RS 140? Help Guys, I need them for some serious music playback. Thanks!

If i were at your place, i would buy the Sennheiser RS 140. I had RS 120 which was not good at bass when the volume is high, else on low and medium volume quality is excellent. Also it is the newer version then RS 120, so you need not worry about it. You can always adust the Bass and Tone of music from the software side so no need to worry about 120 too, but you will loose the quality touch of pure bass...

If you want some serious and quality music, you should go with RS 130, its better then RS 120 anytime as well it is better then RS 140. RS 140 has closed cups so the sound doesn't loose out but your ears, that may be dangerous. Wile RS 130 has Open cups and sound can move directly out from the other end. But you may disturb people around you... Bass quality is excellent..! All the best!
