So I ran over my cheap BT headset this morning on the way out of the house. I found it's sad lifeless body on the garage floor when I pulled out the lawnmower. Now I'm looking at replacing it. I know people love the T1, but the S4 intrigues me. I only ever use my headset when I'm driving, and not having to shove something in my ear would be nice. Anyone have any experience with the S4? All of the negative reviews I can find are from people who were upset that the USB cable was a different size or the like. Any thoughts? Thanks in advance.
