The 4th pair is balanced enough to where I dont notice for more than a few seconds after I start listening to something. There is so much described about the times of early inventions in electronic industry to present day iphone. Perfect for watching movies on my computer when I travel (the computers speakers are just a touch too quiet sometimes). So until I get the replacement my rating will have to stand. I had one with hooks that couldnt stand up to the weight of winter coats, this does. The biggest advantage of this type of strap for me is the set up. Suede is very soft and stretchy, but there is not much cushioning beneath ball of foot and very little arch support. Padrísimos, cómodos, resistentes justo lo que necesitaba para mí Mila los usa para ir a la alberca, en días calurosos y hasta ahora que le quité el pañal por si hay accidentes Clarity, ease of install, and performance are all great. This should be a standard accessory for the iPad Pro.
