Use is very easy. I have a studio and these have very nice separation and dynamics. I gave up online gaming years ago so this review is for Movie watching. They stay on the device better than the originals as well. I wanted a different band for my Apple watch, other than stainless steel/metal, which is what Ive always worn. The racks were installed in less than 40min. Bluetooth has definitely come a loooong way. However, I am interested if someone does know of the perfect bar bag--room for the XR and narrow enough to not make knee contact, but still roomy enough for snacks, gels, map, etc. The last one I used under the sink just to hold sponges, and brushes. They fit perfect for a size womens 10 even though in some shoes I wear a 9 1/2.
