I have really small ears and a small head. Mas rígidas que otros modelos de la marca. The rack is installed perfectly - up and running. Recording studios spend hundreds of thousands of dollars to achieve the highest degree of audio accuracy so musicians, producers, and sound engineers can make informed decisions about the mix. Overall not impressed for spending what we did. The downside of the mute button is that its a bit too easy to press, so when the wire swings and the button hits my chair, it will sometimes mute the mic by accident. I have been through medications and physical therapy. The hook portion is also a little shorter in height, so they dont stay as snug in my ear. If looking for a supportive sandal with arch support look elsewhere. I am here to say they RUN BIG.
