I'm planning to buy this headphone(with mic)
Original Sony MH EX300AP Handsfree Headset Earphone FOR Sony Xperia Phones Black | eBay
SPECIFICATIONS
General
Case Type: Nylon case with slide out tray to hold headphones
Magnet: Neodymium (440kJ/m3) for outstanding bass performance in a small driver

Audio
Driver Unit: 13.5mm diameter, dome type (CCAW adopted)
Frequency Response: 5-24,000Hz

AS far as i know,
Bigger driver unit means better
Larger frequency range is better
