The newest version of Wi-Gear’s iMuffs, model MB210, include an adapter that connects to your iPod’s dock port and lets you listen to your tunes wirelessly. The iMuffs resemble street-style headphones, with a curved piece of plastic that goes around the back of your head. The plastic is flexible, but those with large heads may find that the headband twists when you stretch it to fit around your melon. If that happens, it’s hard to get the earphones to lie flush against your ears, leading to lots of sound leaking out and annoying your fellow commuters. The headphones are light and easy to wear, though, if they fit your head right. It would have been nice to be able to adjust the headband.
