Review on Improve Communication and Audio Quality with MEE audio ClearSpeak Universal Headset Cable with Boom Microphone in Black by Kevin Bigelow

This is a great accessory if you use your phone to listen to music in the car. A button on the cord lets you pause or skip to the next track without looking at your phone. Note that the end with 4 rings around the stem of the plug (which is the right angle end on this device) must be inserted into the phone for this feature to work. The other end with three rings around the barrel of the plug should be plugged into the AUX jack. It's also lightweight and very flexible, which is great when your phone is in one of those sticky windshield mounts. Good value too.
