After I added the other two strips it works great. Vibrant colors and great quality. Make it longer and add a couple of washers/spacers to make the fit adjustable to the receiver. Also I have wide feet and so i got a wide width and they fit perfectly! I ordered a size 7 pair and when I received them, they were 1 1/2 to 2 sizes bigger than they were suppose to be. I was really surprised, I bought small and though "oh no these arent going to fit" but I rolled them between my fingers and theyre wonderful and sturdy buds, they perfectly adapted to my ear canal. So overall, my fault for not reading the listing properly but even that aside it’s expensive for what it is and I would say there are better options available. I often use it with only the right earbud inserted in my ear and it works pretty well (the microphones are on right side). This time I bought 2 sets. Its easy to remove any stones or sand from the shoes just by shaking your leg.
