Pros Very good bass an are very durable.
Cons nothing at all
Summary These are really great and are a bang for your buck also I reccomend to buy the ones that have the volume control if you have an IPod Touch/IPhone
Pros Sounds were above average on my iphone. It's nice to have the volume switch on the headphones. They were also comfortable while listening to music.
Cons I didn't like the chord. For a Sony product, major disappointment. I actually broke them within a week of owning them. The chord was pulled a little less than hard and it fell apart.
Summary While great in the sound department, its not worth the 25 dollars in my opinion. I bought a pair of skull candy for 15 and they weren't the best sound, but a lot more rugged.
