I LOVE this little guy! I was looking between these new models from Logitech and the Jawbone and I made the right choice. It's so small and packs a ton of battery life and sound. I have read that on Logitech's earlier model that it sounds like the music is coming from a can. I found if you turn off your EQ in your iPod settings it fixes that from happening. The Jawbone does have more bass but $70 more. It has surprisingly good low end for a speaker only 3 inches wide. I can crank it up and fill the entire apartment with rich and clear music! Its quite impressive for something that fits easily in a backpack or purse. On top of the nice sound it projects it has a simple and fun design. highly recommend this product! Highly!
This does a great job with voices. Confrence calls and movies are easily heard, people sound right and you will sound good to the people on the other end, plus the microphone is pretty good, you can be several feet away and be clearly heard by the people on the other end.
Music sounds good, not going to shake the room with bass but again, vocals come through nicely and acoustic instruments sound fairly good. Best traveler solution I have come across.
