Like many other reviewers here, I have had repeated problems with the build quality on this particular set of headphones.

The problem occurs where the wire meets the audio jack. It becomes loose with normal wear and over time you will lose audio in one or both headphones.

I purchased the product in June, returned for warranty in August, and now in November, I'm returning them again.

They seem to have sped up their replacement period to a matter of 2-4 weeks, but that is not excuse for a poor product which, from these reviews, clearly has a well-documented issue. I'd look elsewhere.

Pros: Probably the most attractive headphones on the market; sound quality above average (average being the factory-shipped ipod headphones)

Cons: Poor build quality

I bought these bass freq earbuds a few days ago. LOVE THEM! They have excellent sound quality and are very comfortable. Really outdo the Griffin earbuds by far and Sony!!

Stay away from these earphones please!!!!!!!! They are not very good for any person who relishes audio in any way. I picked them because of good reviews by CNET and when I got them I was very disappointed with the quality. I gave them to wife, because she isn't as picky as I am, and within two months of use the bass completely stopped working in the left headphone. Not worth the money at all.

These are good earbuds but not the bass I was hoping for. I like them. They are better than the earbuds my ipod came with but they really aren't what I would call bass heavy. They are very comfortable but have a tendency to fall out while I am running. I like them and they deserve three stars but i wouldn't buy them again.

I bought one pair for my husband. He said they worked fine! He has used them for a few months and never had any complaints.
