Very nice looking sandal for the money! until we tried to pair our devices to our phones. Didnt get a chance to wear them in before wearing them to work the 1st time. I decided to obtain the V9 Bluetooth set to see how these work. Its tough to get the garment on, but once its on I think its pretty comfortable and really holds me in which is great. The Shure 1540 is the only pair I have heard that covers the entire spectrum evenly, in a natural way (with natural I mean that a piano sounds like a piano, a wooden string instrument like a wooden string instrument and Jimmy Hendrix sounds like Jimmy Hendrix and a bombastic electronic score sounds bombastic). I cant see contact details for this retailer I need the buckle for one of the sandals or they will need to be returned . They?re crocs so they?re about as ugly of a shoe as it gets. Buttons operate reliably through the soft leather. It wont really have any use while music is playing, unless the music is really quiet.
