Couldn't have said it better myself. I'm now down to only my Studio 3 and HD1. Sold the H.ear On 2 today. The Studio 3 isn't going anywhere for me. The exciting sound, ease of use with all my apple products, comfort, and fit are all just perfect for me. The only thing I'm deciding now is if I'm going to stay with the HD1, or swap them out for the QC35 II or PX, both of which I've had before LOL. My only issue with the HD1 is the volume when in bluetooth, lack of AAC, and comfort. It's not that it's uncomfortable, I just have to get the positioning just right and sometimes I have a hard time doing it. Both the QC35 II and the PX were more comfortable for me for long term wear.
