Summary: I just upgraded from the Plantronics 230 model which was a piece of junk. I was going to go with the Jawbone but for the same price you can get this beauty. I personally have no problem pressing the multifunction button, and my Iphone can control the bluetooth volume level from the phone with the volume keys when you are in a call so this will never be a factor for me (the small button that is). This is my first day with it and when I used it for the first time I could hear the difference from the lower model and personally I am able to hear better than with the Iphone regular earphone. A plus is the 3 different sized ear pieces that come with it in case you have out of the ordinary size. The one that comes on was ok for me but then I went to the biggest one which has worked great. I can feel it in my ear but its not uncomfortable and stays in place very well, it also isolates the sound more so I normally cant have it above half volume otherwise its pretty loud. All in all, very happy with it.
