Once in a while you get something and like it so much you wonder why you hadn't gotten it a long time ago. Or, as in my case, why you didn't use it.
The headset's sound is much better than that of Apple's OEM included with the iPhone. For the first time, I can enjoy the bass and really control the multifunction button (that ends calls as well as controls music playback), thanks to its round shape and larger size. The iPhone's included headset has a very tiny button that's hard to press on. It was almost impossible for me to make a successful jump to a previous track.
What I like best, however, is the fact that the Platinum i-Series is black instead of having the same white color as Apple's headset. Now I can blend in without people looking at me and thinking, "Oh I know, you got an iPhone, all right."
Other than the iPhone, the iHarmonix Platinum i-Series headset is compatible with any 3.5mm-equipped mobile music device. Its in-line mic and multifunction button work with the iPhone, iPhone 3G, and BlackBerry.
Technically, the headset's earphones feature 11mm drivers and neodymium magnets for dynamic sound and bass. They also have brushed stainless steel front housing and a polished metal alloy rear casing to provide a cool-looking appearance.
The headset also sports a gold-plated 3.5mm audio jack and comes with soft ear gels in three sizes for a comfortable fit.
I got the headset for free and you can get it for $60, which I think is a good price. iHarmonix also makes other types of headsets that are more affordable.
