I have a motorola cell phone and tried several other headsets (and earsets) including the one that came with the phone. None worked as well as this set. Either I couldn't understand the other person (sound is badly muffled) or be understood. With this set, I use it in a way that wraps around my head and so far it works great. It's a bit bulkier than other earset and takes two hands to put on, but once it's on it's very comfortable. So, I just put it on as soon as I get in my car in case someone calls me while driving (my phone automatically answers incoming calls when the headset is connected). This is a definite keeper.
