Got this to replace my Brooks Cadence, which were showing their age. Going to find a seamstress to take it in and cut the zipper flap out so its not a complete waste. But I have neuropathy in my feet and they were not comfortable for me. It took awhile for me to get used to the enhanced audio, since I could hear things so much more precisely and clearly over my Gold headset. I don?t recommend. They are comfortable and solid. Pros:- Really small, portable- Works very well on USB or paired to a bluetooth phone- When paired with iPhone (possibly others), device battery level displays on phone- Clear audio on both sides of communication- Battery lasts forever- Easy to operate and understand. They look brand new all over again! Better than many others! The 3 shelf unit is inconspicuous so Ive decided to order another but not to stack.
