The sound quality is mediocre, but it plays reliably, even after I have accidentally dropped it on the floor. The Fidelios were also heavier and not as comfortable. I wore out my last set of Uggs after years of use. Hopefully these will last. Using this with my ps4 and computer so i can use my wireless ear buds. The many traction increasing veins at the bottom of the shoe are a double edged sword, try to clean them out every day. With Bobs, they have a memory foam insole that is pure heaven, but does flatten and wear down over time, rendering them to any other flat on the market. Not gonna pretend these are actually COMFY. Conclusion: Belkin is a notable and reliable company on the whole. Very easy to install very nice looking did have to kinda fold the phone part some so i could use it while it was on the dock but outside of that it’s great
