Very disappointing that it was so hard to get them dually/binaurally connected! Dopo 4 anni questi sandali sono ancora come nuovi. I have a studio and these have very nice separation and dynamics. I had boots with zippers before and with the shoestrings loosened these boots are surprisingly easy to get on and off. However the mic is FAR better, and sounds perfect. Browsed alot. This is our second time buying for our 9 year-old, only after she outgrew the last pair of Bearpaws from 18 months ago. One advantage is that I leave it in the car and now I only have one cable to connect to the phone but I still resent having to buy it. I definitely thought with all the good reviews that this product was going to be the product for me to use from here on forward, but sadly it was a waste of my time and money. I prefer a wire to vagueries of wireless connections and batteries.
