These out of the box with NO burnin blew a $120 pair of Sony noise isolating headphones out of the water. I was astonished -- I had lost the sonys and got these. It so happened that the sony's turned up the day these arrived in the mail, but the sound on the new head phones was so much better, I had to keep them. This is all substance over style. they aren't sexy, but they feel great and sound great. I am a bit of an audiophile, enough so that my home stereo plays on sonus faber concertinas and I only rip in flac. For the money and for a bunch more, the sound on these little earphones is amazing. I should also mention these feel built to last and the company has a great reputation for customer service.!
