I was looking for an inexpensive set of heaphones to replace the stock earbuds that came with my Ipod Shuffle and my Sansa Clip+.The Sennheisers are a big improvement over any earbuds or in-ear buds that I've used.The sound is well balanced with very good stereo separation.Mids and treble are both crisp and the bass,while not booming,comes through very clearly.In fact,I could tell whether the bass player on certain tunes was using a pick or plucking with fingers.I have a larger than average skull and these headphones are fairly comfortable.Get these if you want a cheap set of 'phones that sound expensive.
