Bluetooth headsets are great and all but the problem with all of them is that the microphone is way up by your ear. No matter how fancy the mic is, there's always gonna be echo problems and sound quality problems with it being so far from your face, especially when you're in a loud or crowded area.

The solution? Put the mic closer to your mouth, duh. That's exactly what this concept Tie Up mic does. It hangs around your neck, and you simply pull it up as if you were tightening a tie to answer the call. When done, pull it back down. It's a simple way to make sure you're always heard when you're talking, which is a pretty important aspect to something designed to let you talk on the phone.
