Here's a sampling of devices that will bring music to your ears.

Orbit
$40
Altec Lansing

Upside

: Convenience

Downside

: Needs more bass

The new Orbit portable audio system plugs directly into your MP3 player to create sound, whenever and wherever you happen to go.

It runs on three AA batteries and is about 3.5" in diameter. You can listen to the device with it pointing directly up or turn it on its side for a more directional approach. For the price, the Orbit is not bad, although the bass could have been beefed up a bit. The stylish design of silver and black should go with most MP3 players. The Orbit is lightweight, easy to carry, won't bog you down and it's an easy way to hear tunes while on the road.

Pure-Fi
$150
Logitech

Upside

: Great sound

Downside

: Size

Pure-Fi compact speakers for the iPod is not only portable but has incredible sound.

The 10-hour rechargeable battery comes with a battery-level indicator so you can monitor when it needs to be charged. An international voltage AC adapter is also included.

This provides a full and balanced sound with great bass and it supports all iPod models that have a docking connector.

At approximately 13" in length, I'd like to see this cut down in size, but size matters -- especially when it comes to speakers, and the Pure-Fi delivers.

Airdrives
$99
Air Drives

Upside

: Versatility

Downside

: Price

Earbuds can mean havoc for the mobile executive who might not want to miss a call or a gate change announcement.

Airdrives are different in design because they wrap around the ear, enabling you to hear your tunes but also function on the run. They also easily adjust to your ear, unlike the horrifically hard and stiff ear buds that come with iPods.

The sound is great on these, but with the price of headphones coming down, it would be nice to see these priced a little lower as well.

Unlike YouTube.com, you won't find many cats using the toilet here. Instead, you'll find tons of hot-off-the-cellphone videos from Iraq, newscasts, breaking weather stories and reports from citizen journalists around the world.
