The scent just might be your skin burning and wishing you hadnt used this. Not memory foam I dont think but they may as well be. Its shape sits in my ear well also. Still closed without feeling like i was going to break it, and high enough that the bindings on the board didnt touch the paint on the roof. Don’t know how I ever did without it. I have received the Brabic upper arm shaper. Too much higher-midrange and it sounds hollow or echo-y. The development of relationships among the characters was compelling. I purchased this case to replace the previous one that just didn’t fit my phone. I also wanted to use it to listen to Hi resolution streaming ( Qobuz).
