I couldnt figure out how the adjustable strap would function on the average foot: one hole is super-tight and one hole is super-loose. I have bought them for a skiing holiday but havent taken them off since trying them on. These shelves were exactly what I was looking for. I probably would like a bit more bass, but its acceptable and the mid and high-range sounds are very good. When something is this unbelievable inexpensive, that tends to be why. But that isnt my biggest concern. Very pleased with the quality and sound. Worth the money for the comfort and quality. Very colorful fit great. With the TOZO pair, the connection stays solid and reliable.
