Tried another popular brand, this is the best there is so far.Syncs well holds signal 96% of the time once in a while skipping for a few secs, but not near as bad as when I wold knock my corded earbuds out.Great for working out, leave ipod somewhere close by or in a pocketGreat for travel, leave pod in the bag.Awesome for practicing tennis, hand the IPOD on the net post.Good for phone use.Good for jogging on the open road.Great for jogging on a treadmill.Buttons take a little practice and once in a while when I wake IPOD have to reconnect to IPOD to get blue light blinking.Two things to improve, loose the blue light facing the screen, have to cover it up when watching video. Could be a little louder but I dont notice too much.Fit for me is perfect. Syncing takes a little practice but is fine.OHH, there is a version with the Motorola transmitter, get that one.
