I bought these for my brother-in-law for his birthday and he immediately fell in love with them.  He has an iPod touch and I wanted to get him something bluetooth for it and this was the best thing I could find.  What I didn't realize is that it would work with his cellphone at the same time.  He synched it with both of them and if he get's a call while listening to his iTouch, he just presses the answer button and it immediately switches to the phone.  As with everything though, the experience can't be flawless.  First, amazon shows that this one is the blue accent model when in fact it isn't, it's is just straight black.  This isn't a big deal though I did intend on getting blue.  Second, the song controls don't all work with the iTouch.  This isn't the fault of the headset however or I would have rated it 4 stars.  This is due to Apple not fully implementing the bluetooh spec yet.  I assume they will at some point in one of there updates and it will they will start working.  In summary, these are very much worth the price and I would buy them again and again.
