As we all know when iPhone 3.0 hits this summer it will enable iPhone users to use Bluetooth and stereo headsets with both A2DP and ARCP protocols.
theiphoneblog took a look at the Motorola S9 Stereo Bluetooth Headset for iPhone 3.0 previously and now looks at the Motorola MOTOROKR S9 HD and has found it offers great sound.
Other factors they found where it has good battery life, is well suited for on the go usage, is light and comfortable, while on the down side it may not fit all head sizes and isn’t suited for lying down.
