"Logitech today introduced the Logitech® FreePulse™ Wireless headphones, its stylish second-generation cordless headphones for iPod® and MP3 players, which deliver the complete freedom of experiencing digital music with no strings attached. The FreePulse Wireless headphones are half the weight (only 2.1 ounces/60 grams) and size of Logitech´s award-winning first-generation product — but, they are more flexible and durable, thanks to the high-carbon spring-steel headband. The new version delivers twice the performance as well as enhanced bass with its special bass boost feature. And it offers improved wireless performance with Bluetooth® 2.0 Enhanced Data Rate (EDR) wireless technology. People can simply plug in the adapter to any player with a 3.5 mm headphone jack, put their player in their pocket and enjoy their music wirelessly. No more cord tangles, snags or kinks."I'd like to hear from Digital Media Thoughts readers that have Bluetooth headphones - I've never used a pair before, largely because I strongly prefer the in-ear headphones. Do most Bluetooth headphones sound decent, or does it vary widely based on brand? Anyone own the previous version of this Logitech product?
