SYNC by 50 Cent

If your lovebug has been especially sweet this year, treat them to one of the best-sounding headphones on the market.

50 Cent's new wireless headphones from SMS Audio integrates Kleer wireless technology allowing up to four listeners to simultaneously rock from a single source. Additional features include 16-bit digital sound, full on-board controls and passive noise-canceling capabilities. Here's our original review. Wireless cost a pretty penny - $399.95 - or choose a wired version for $299.95.

Soulra XL Sound System with Solar Panel

This solar-powered, heavy-duty sound system promises to play all day or, to be more specific:

5 hrs to fully charge in sun (depends on sun intensity)
8 hours of playback (depends on audio volume)
4 hours to fully charge iPod/iPhone (depends on model)

Snap in your iPhone or iPod to play while the 72 square inch enhanced monocrystal solar panel
recharges the lithium ion battery pack. Your Valentine will love you for it.

$250 at Eton.
