I'm forever on the endless search for retractable headsets for my cell phone. I came across this about a year ago after breaking the winder on an older set (which I absolutely loved but can't find it anymore).I like the boom mic on this set. It's flexible and the person on the end can usually hear me loud and clear. It makes the ear piece a bit heavier and that's only a bit bothersome if you're on the phone for more than an hour.I like that you can unwind the cords by pulling in one direction (unlike the Jabra WindUP) and it's got a button to retract. The housing is way too big so it's not very convenient to put in your pocket. The "talk" button in the center doesn't work on mine, nor on the set that I ordered for my boyfriend. Amazon could have sent me 2 defective units but since I don't have the need for it, I didn't bother to send them back.My search continues...
