These are decent for the money. If you have an active somewhat clumsy toddler I would recommend getting a different pair of sandals. He had an intense imagination, vision, and belief in things that had yet to be discovered. I tried a couple of wireless headphones and had issues with sound isolation (dangerous), wind noise and that weird thumping everytime your foot strikes the ground. This is one solid piece of protection! Good bass with authority. The price was reasonable, my husband said it installed easily and its very quiet. It is fabulous. The bass is a lot more pronounce if you like bass heavy music. The wheels are very smooth and it is easy to push/pull the rack across the floor.
