ProsGreat sound qualityWorks perfectly at home and in the subwayStress free connection to my iphoneConsWhen I'm walking down large streets, such as Broadway and or near large office buildings the sound cuts out. It can get really annoying sometimes, and if you get irritated easily don't buy these for walking around this or other large cities. I found if I put my iphone in my front shirt pocket, the cut rate is cut by 90 percent, but I shouldn't have to do this.Apple doesn't allow non-apple equipment to control anything other than the volume, so you can't change the song from the headset (Sony customer service told me this)I also tried to connect my Sony headset to my Bluetooth enabled HP notebook. I was able to connect the devise, but there was no sound. I called HP and they told me the Bluetooth frequency wasn't compatible. I don't know if the customer support guy I spoke to in India, didn't understand me or didn't care, but in the end I couldn't connect them. This is not a slam to the headphones, just a warning to other people to double check before you buy, especially if you plan to use these exclusively on your computer.
