The Apple iPad is a great music player, whether you're relaxing or doing useful work. You can plug in to listen with headphones, but unplugged the iPad speakers are a tad underpowered if you want to really enjoy the sound.
A better answer is wireless speakers like the Logitech Wireless Speaker (see earlier post -- now for $85), which let you continue to listen without being tethered to the device.
Separate powered speakers also let you crank up the sound to better fill a room, so Logitech has cranked out the new Logitech Wireless Boombox speakers with even better sound for $149.
The Wireless Boombox has eight (yes, 8) drivers to separate the sound frequencies: two 30-inch neodymium drivers for full mid range, two 1/2-inch neodymium tweeters for crisp highs, and two 2-inch passive radiators for deep bass.
The result is clear, clean sound even at full volume (which won't blow out your ears).
You then can stream stereo audio wirelessly up to 33 feet over Bluetooth, from a PC, iPad, iPhone, iPod touch, or other devices -- so your system can remote control playback on the speaker.
The Wireless Boombox plays for six hours with its removable rechargeable battery, or can run powered using the included AC adapter. It has an auxiliary 3.5 mm input for wired playback and a flip-out stand.
As a Boombox, it is a bit bigger than the Wireless Speaker (approximately 15 x 5 x 2 1/2 inches compared to 10 x 4 1/2 x 2 inches) -- but you'll understand why when you hear the sound from the eight vs. two speakers.
