The black with metallic dark grey colour scheme has a nice finish and feels very high quality. stylisches Design, viele Knöpfe und LED Beleuchtung deutlich über der Klangqualität als Priorität stehen. I also dont find them to be overly wide, unlike other reviewers. Ive found that Vionic has good slippers but the footbed is too hard for other shoes. I have this sandal in 4 colors (2 or three pair each) and they all fit well. Weve tried multiple sets of batteries, and have checked to make sure that no wires were pinched, etc. Razer had me update the firmware, which helped for a couple months then died. Safely packaged as well. Quite a snug fit so no good for wide feet. All different Bluetooth headsets Ive tried (even high priced ones) have some issue for me with lag time, fit or sound.
