ive tried many other blu tooth head sets and none of them worked for me so i was looking for a wired head set but my cell phone uses an adapter and i didnt like that so i thought i would try this wep 200, and it worked great but kept falling out of my ear, i even wore it in the swimming pool because i forgot i had it on, i dried it off and it kept working.late this spring it finally fell out of my ear into the yard and i lost it. this fall the neighbor kids who play in my large yard found it. it was covered with dirt and had survived mowings twice a week the sprinkler system every day, thunderstorms and just being in the damp outdoors for 3 months.to make a long story short, i'm still using it, i have it on right now. i solved the problem of it falling off by purchasing the ear hooks for it, they are cheap so i have bought several and they really work.Samsung WEP180 / WEP200 / WEP210 Bluetooth Headset Hook [OEM] AAET180SBEBSTD
