The rope and pulley glide smoothly. Im just taking off one star because the wires are very very thin and fragile feeling. Nice product -- I will add a 23rd 5-star review to the unanimity. I also get ?wow? responses from audio pros who get to try them. I bought this silicone case a few months ago and have been pretty happy with it until yesterday when it ripped right where it folds to close the case. That being said this headset IS however, very comfortable and the sound / microphone quality is just as nice as my old headset (may she rest in peace). We also use the hooks to hang up the kids masks. They?re so supportive and so comfortable. The Scuffs looked very nice & manly, but that is about it. I would like to thank the seller for this product.
