Any options for a 3.5mm in ear headset with inline mute switch?

I want to move away from a big clunky headset in favor of something in-ear, but an important feature to me is being able to mute and unmute on the fly. Are there any options for earphones with inline mute, *or* ways to add inline mute since it's just cutting off the signal to the mic contact on the 3.5mm jack?

I've looked at the Steelseries Tusq, but if it does have mute it doesn't indicate such anywhere on the product info.
