If your a runner like me and struggle with earbuds falling out then consider these. They have a rubber wing which as you can see in the image helps to pressure the earbuds so they dont move. I have used them myself and can attest that it works! Hooray finally earbuds can be mine..
With a microphone and external control as an extra bonus the XT Free from Skullcandy is an excellent sport earbud solution. Being lightweight and stable in the ear and did I mention the sound is great. Good base and detail very enjoyable sound.
