This item works surprisingly well. It is compact to carry around and the built-in microphone works incredibly well. I had a hard time believing that a microphone at my ear would actually work, but it does. The sound cleaning technology also works well. Take the time to find the eargell that best fits you (it comes with 6 different sizes) or it can be uncomfortable. Once I found the right one, it was great. I was able to talk on a two hour call without any discomfort.
