Nokia Purity In-Ear Headset by Monster
While I was in MWC 2012 for Nokia Press Conference, they gave out the Nokia Purity In-Ear Headset by Monster to all the attendees! Of course they are not in retail boxes to prevent you from reselling them.
If you want to get it in the Nokia retail shops, they are available in 4 colors, Black, White, Cyan & Fuchsia (Pink). They are retailing it for S$148.
