These offer all that but a whole lot more. I am so glad I brought tgem I would not say that I tested the full 100ft range claimed by the product listing but definitely got to 45 - 50 ft away without issue. I love the controls on the ear piece instead of on wire. I accidentally pause or change the volume, when adjusting them in my ear. Its an extension cord, yes, it extends your outlets 6 ft! Even though those are advertised as spice shelves they fit cans and jars very well and allows a great view of all products on hand. I try to pull them forward some between some sets and I have about average size hands (I use smalls for hospital gloves) maybe I have long palms I don?t now. One thing I will be interested in is when Im out and about, where there will be much more environmental noise, so perhaps I can add to that at a later date. Fit true to size chart.
