Issue:One big issue I had was a constant static/white noise, regardless of ANC status. If you want to change the bass or equaliser settings in the accompanying headphones app then the codec quality drops from aptX to SBC. Not much arch support. held up pretty nicely. How low can you go? So irritating! For those not suffering from this condition these slippers would feel wonderful. The 10 was snug at my toes but flopped off my heels when Id walk. Also, when I do use them and I receive a phone call the person on the other line says it sounds likes theres a lot of static. After that though, Ive had no problems with the shoes.
