I listened to a Metric song and it was super clear. I was concerned about these being a low quality copy of another brand, but I was delighted by how well they held up. My advice to you is to perform the same test I did as soon as you receive it BEFORE trusting it on the road. IT AUTOMATICALLY CONNECTED TO MY HOME PC WITH THE USB DONGLE. Trust me, Ive installed it both ways and it looks/works better if you disregard this information. When I put my shoes in the left hanger tore through the fabric. The balanced pads help dampen the upper end. They were amazing with sending me a replacement right away without me having to package & return the heavy box, wait for a refund through Amazon, and reorder. I have owned these flip flops twice now. I just received these and they are a little big, my foot lifts up when I walk.
