Summary: When I saw this set of headphones on amazon, I thought to myself about how great a deal this was for what i thought would be a great pair of headphones. When they first arrived I thought they looked very good and well designed. After taking some time to adjust the ear pieces I found that they fit well. Then came the important part; the quality. The sound is terrible! You have to turn the volume up quite loud in order to hear the music. The sound quality is upsetting.
Summary: I've went through two sets of these in the past 18 months or so. The first set lasted less than a year, but I liked them so I bought another set thinking I just got the bad apple. It happens. The second set lasted less than five months, but just outside the warranty. I emailed Sony Support, they emailed back and said that I had to take the issue up with Customer Relations. No offer to forward my email to them or anything.
Summary: Purchased these on 2011 Aug 06. Worked fine since then. Sounded good. Although I would occasionally have to "refit" the left earbud in my ear, but can you expect a single set of earbuds to be a perfect fit for every person? I don't think so. Today, 2012 Sep 01, the left earbud stopped working. That's why I'm giving these the lowest rating. If not for that, I'd give them 4 or 5 stars.
Summary: In order to function, the product requires that you push the ear buds completely into the ear. Otherwise, just a barely audible tinny sound. Issue is that as soon as you start to perspire & move around, the earbuds pop out. I had to keep pushing them back in literally every 15s or so during a run. I tried every earbud size that shipped with the product - all with the same result.
Summary: The flexible over the ear piece came off too easily - lost, gone with the wind. Hmmm 30 dollars. I bought this headphones for my 11 yr old son. The original earbuds for his Go bible keep falling out so I figure these soft flexible ones will help keep the earbuds in place while being gentle on his ear lobe but after a week they came off easily and he lost them. I chose Sony because I have been buying their products for years and I am generally pleased.
Summary: First headphones I've ever found that fit so well for running and cycling. Comes with three different size hooks, so you can find the perfect fit. Incredible sound too... better bass than Apple earbuds. And the extension cord is awesome... I use the extension for cycling (to drop under my jersey) then the basic short cable is great for clipping an iPod shuffle to your shirt or cap. Highly recommended.
