Just bought a pair for my Alesis DM 10 drum kit. Originally, I bought some cheap headphones thinking that it will be ok...foolish. DM10 sounded subdued and the hi-hat did not sound crisp, snare was off, etc. Once I plugged in the EX29, the entire drum kit jumped to life. The sound was sooooo clear and crisp. All instruments (pads) came to life! Yes, I am a novice who enjoys clear sound, and EX-29 is great. I don't know if it is good for MP3s...but then again (MP3s compression is poor anyway). I do not like Beats or whatever they are, Bose is great but pricey, EX29 are right on the money. For 129 bucks (I got the black ones), the sound quality is amazing! And the best part - they are made in US :) They deliver everything that is being advertised about them. Oh - almost forgot - don't be put off by the cheap looking plastic fold - it is made like that for a quick repair. If you care more about looks than sound - get something five times the price of EX29, otherwise, enjoy your DS headphones! Cheers!
