If you are after that "thump-thump" kind of exaggerated sound don't buy these. The K240 headphones are "accurate" and don't add anything to the sound.  People who are mixing or editing sound prefer "accurate" but many music listeners prefer the accentuated bass.  These headphones let you hear what is on the track an add nothing to that.  The sound is transparent, as if you were not wearing headphones.  Also being "semi-open" this means they do not block sound in either direction.  This open design adds to the not-wearing-headphones sound but is not practical in some settings.  Remember these are STUDIO headphones.  They provide accurate sound for engineers and are best used in a quiet studio setting.  If you are a music listener at home then the best use of these headphones is for classical or jazz in a quiet living room.  or for critical listening to any music, for example recently I was trying to listen to Paul McCarney's bass guitar lines in some new and old recordings. With these I can hear every note and also how he played the strings with his fingers.  The K240 provide an accurate, reserved sound for that kind of listening, not the popular flashy and thumpy sound.
