I have owned about 5 or six different bluetooth headsets since they came out on the market several years ago. I hated all of them. I could never understand why these companies couldn't make a bluetooth headset that held a charge, was comfortable to wear, had no echo or static and provided crystal clear sound. I could also never get the volume loud enough to block out outside noise without pushing and holding the headset against my ear canal with my finger. Having to push the a headset for a long phone conversation gets tiresome very quickly. To say I was hesitant to buy this model at such a cheap price is an understatement. However, I carefully read the reviews and decided to give the one a try. The bottom line - I love it. Everything I complained about with past headsets has been solved with this little gem. It's tiny and light, very comfortable, stays in the ear extremely well especially with the included over the ear anchor. The sound is crystal clear, loud and I can hear the people I am speaking with as if I was talking directly into the phone itself. And even better, the people I'm speaking with have no idea I'm even using a headset. I can't tell you how sick I was of the person I was speaking with asking me what that horrible echo or static was!! As for people complaining that it won't stay in their ears - they're not using the correct in the ear attachment of which there are three sizes included OR they're not using the over the ear anchor. You can do jumping jacks and this thing won't move or fall out. I highly recommend this headset for everyday use especially at such a low $30 price tag. Great job Samsung!!
