Koss P9 - perfect for Mobile users on the move

The Koss P9 In-Ear Headphones with Volume Control features a convenient volume control feature that can be easily adjusted on the fly. Lightweight with a comfortable behind-the-head design, these headphones are made to be worn for long periods of time and are perfect for listeners on the go. Compared with the regular headset available with the N95 the Koss P9 offers almost the same output in terms of sound, but the added bonus is that it has much more stylish looks.

One of the other applications that I found for it's side-firing design is that it's more wearable than usual headsets when your on a motorbike - it's design is kind of aerodynamic that there's less chance of the headset falling off when you're at high speed. Moreover the side-firing technology means you're more likely to hear horns and other external sounds from your surroundings - leading to a safer experience. Obviously no one would use Noise Cancelling Phones when on the road - you won't even hear the Traffic Police man's whistle!!

On the other hand it's sound isn't that much of a reason to go for it. It lacks the bass that Koss advertises so much, and the some frequencies are really bad. Upon comparison with the Standard Nokia headset that comes with the N95 - the Koss P9 is somewhat 80% there.
