Wireless earphones are becoming quite common. You often see cellphone users walking down the street with the alien-like appendages protruding from an ear. And even in the world of iPods, where the famous white earbud cord still rules, a half-dozen or more wireless headphones have been introduced.
But there are problems with going cord-free. In the case of cellphone wireless headsets, loud street and crowd noises make it hard to hear. And the wireless iPod headphones have been big, bulky units of unremarkable audio quality.
Now, some wireless earphones address those problems. For cellphones, a new wireless headset called Jawbone promises to filter out all that background noise. For iPods, new wireless earphones called Ety8 promise to bring small size and great sound quality to the wireless category. Both products use Bluetooth wireless technology to transmit audio from the device to the ear.
I've been testing these two new products and have found that each lives up to its claims. Both are advances that have real advantages over the more standard cord-free competitors. But each also has some drawbacks that might deter some folks from using them.
