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 don't move. I have used them myself and can attest that it works! Hooray finally earbuds can be mine..
My experience with Bluetooth headsets is zero. Does this make me a good reviewer ? I think so. I will come at this without prejudice and without knowing what this kind of device ought to be able to deliver. I am running an iphone 6 as the mobile I wanted to use this with.
