I just left my position in the restaurant but if I buy non-slips again I will return to the Birkenstock clogs that lasted me 5 years! As you can see, the sole has already detached from the rest of the shoe. I purchased direct from Amazon and registered it successfully on the TRX website. Some folks have said that the scroll wheel feels cheap, I differ on this point. I like them so much I may order a second pair for wearing around town. This is a generally flat set of headphones - no one part of the spectrum overpowers any other. I sometimes wonder about 5 star reviews and if the people are paid to write them. Very easy to pair with your phone. Holds all my cards and fits in my scrub pocket at work! They are beautiful.
