I have only purchased/used Thule racks in the past, but I am very pleased with this set. Extremly good quality! This is the only reason to not give them 5 stars. This is my wifes second pair of the MukLuk Morty Slipper socks. Waterproof. They are definitely keepers! I have contacted the seller, but received no reply. Maybe its because theyre closed backed (My AKG K702s sound WAY better), or maybe they need a break-in period. Suitable for about 100 steps before my feet start complaining. While it does an ok job of cancelling out voices and ambient sounds, it actually amplifies the sound of people chewing, typing, sniffling, etc and I cannot for the life of me figure out why.
