Excerpt: I purchased these mainly for use at work since my new employer does not allow streaming audio through your computer. I have Sennheiser brand regular corded headphones at home for gaming, and their quality and clarity have always been top notch.
Pros: Clear Signal, Connects Easily, Fits well in ear, Good Sound, Good Volume Control, Lightweight, Long Battery Life
Summary: I'm comparing this model to a wired Sennheiser model with a microphone for voice calls. There's not a lot of reason to go wireless. The wireless model has good sound quality, but the volume is a lot lower than the wired model. They're nice when out on a walk.
Summary: I purchased this and the Motorola MOTOROKR S306 at the same time. Overview of the benefits over the other. The Sennheiser was more comfortable, cut out less, had better sound quality, better build quality, and had replaceable earfoams.
Pros: Comfort, reliability, replaceable earfoams
Cons: Makes you look like MIckey Mouse (maybe a pro for some), annoying beep when muting, proprietary charging cable (should be micro-usb)
