As others have pointed out, it doesnt always sit flush with the ground, but once theres enough weight on it or you twist its joints just right, it works fine. Fit, comfort and sound isolation on these is better than the stock pads, in my estimation. The right slipper was also slanted a little at an angle, so it looked wonky. I then switched to denatured alcohol that I had stored in my garage and even though it took some time, I was eventually able to get all the old glue off. Do not wash and dry this product with towels. God bless Amazon! The sound from the Grados was really impressive for a true wireless earbud. Received these today and was impressed with how many actually come in the box. The older model got misplaced last month and I turned to this one again. It fit so perfect.
