Having read conflicting information on these headphones let me first confirm that these headphones do have :
(a) remote with 3 button clicker (volume up, volume down, generic 3rd button to pause/play/skip tracks/activate voice control on iphone); and
(b) a microphone (built into underside of remote)
Got these to replace the woeful Iphone 4 apple headphones. What an improvement. The bass on these headphones is like nothing I have ever heard on a set of bud's before. In fact my only criticism is that the bass may actually be too good. I had to adjust the sound settings on my Iphone4 to reduce the bass output as it was just too overpowering. Having made that adjustment all is now good. The headphones sit well in your ear.
The bud ends are slightly angled, not straight like other headphones I have used, so they grip really well when inserted into your ear. Once in they do a good job of blocking out external noise.
The only other issue I had was that the 3rd (middle) button on the headphones was very stiff for the first few days of use and didn't click when you pushed it. It seems to have now loosened itself off and now works very well.
Finally, the microphone works just as well as the Apple mic and is position just right on the headphone chord.
For under twenty quid I don't think there is another set of headphones with this features set out there that can touch the Sony's. Highly recommended.
