Pros: Works faster than the site says, 11MB/s write 45MB/s read. Great product. Fast Shipping

Cons: No cons yet about the product.

Overall Review: If you are buying this for an Android Smartphone (Casio C811 or other), put it into the phone first so it changes the file format of it to what it likes. Then start transferring data.

Pros: They worked great for the time that I had them. When I first got them (from the free rebate!), I was unsure of their performance. They looked pretty cool, and when I put them in, they fit with an AMAZING seal. I like the L jack on the headphones. The ability to wash them was really great, too. They became my lawnmowing headphones, mainly because if I grab the cable by accident, they did not come out. Yes they needed to be reseated in the ear, but at least they did not come out of the ear and into the mower, or get ripped off. Good thinking Pioneer. They soon after became my primary headphones. Treble and Bass are preety good. They are no creative EP headphones, but they deliver sound quality very well.

Cons: The problem with the seal is that they can't be reversed, as in the right headphone does not fit very well, if at all, in the left ear. But who does that? So not a big problem. The other problem is that the seal was so powerful that sometimes it hurt. Yes i am serious. The other problem is that the L angle on the connector was too thick on the outside, and did not sit well in my Casio Commando, which has an audio jack that sits a little inside the device.

Overall Review: They finally went soft on me today. However, I am a huge bass wubber and am not suprised that this happened. In fact, they lasted as long as my creatives. Points for durability.
