They are definitely not user friendly and the quality of sound would probably be good if they would fit properly. I played various background noise on my speakers and there was no difference between low and high ANC. They fit well with thinner boot socks or stockings, and I need a 1/4" heel lift in one shoe. Well now that my toe doesnt bed, I cannot find a pair of good shoes that have an OPENING that is large enough to push my foot through. Wore them for two days and they looked like I’d worn them for a year. 5 in sandals and heels and a 7 in tennis shoes or boots (to allow room for socks) and I got a 7 in these - fit perfect. It was very easy to put together and when I tell you, I sweated my behind off! I tend to speak very quietly and often, people have a hard time hearing my voice. She loved mine. You wont go wrong with this purchase.
