I've ordered the three piece set, it was an unbelievable deal. Walmart sells the car charger for the same price of the set. But....The reason i ordered was because i needed the earpiece only. But it was making just making noise rather than transmitting anything, weird noises in your ear, that;s not what you want from an earpiece. I contacted Amazon, and they immediately sent another set, next day !!! Kudos to Amazon as usual. But the second one had the same problem. The earpiece is the same. I am using only the cover and the charger, but the piece that was the reason to order the set is not working. It's noisy, your party doesn't hear you, you have all this static noise in your ear. I didn;t return the second one, since I am using the cover and the charger, but you definitely want to stay away from this set if you need the earpiece.
