1st of all, I like Samsung products. I have an older samsung earpiece that works great even though I lost the gel piece. I had bought the WEP200 at a computer convention center not that long ago thinking I would get the same quality as my previous earpiece. To my surprise, it did not live to its expectations. The design is great and it's very light weight and comfortable, but it was not working correctly with my phone. My phones have mostly been samsung therefore thinking there should be no compatibility issues, but there were. I would try to answer a call through the headset and it would take the call on the phone not the earpiece. If for some reason I hung up through the phone rather than the earpiece it would get disconnected and I could not place a call through the earpiece until I turned it off and on again. This was very tedious especially when you had your hands full and you wanted to take an important call. I'm not sure what the problem was but it happened to the two earpieces I had bought. I did not pay much for them (20$ ea.), don't know if they defective in the 1st place. Regardless, I would have enjoyed this earpiece but the hassle to deal w/ receiving and making calls made me keep my older version. One thing though that I did not like was the charger, having to remove the earholder from the earpiece ran the risk of losing it...
