Depending on your car, you will feel that. These are beauty. which is a good thing. Bought ATHAD500X along with Philips SHP9500S so this review is a comparison for those that might be trying to decide between the same sets. These little boats are beasts. This belt worked well with my dress. Incredibly comfortable! While you look like an idiot with them inserted upside down and backwards, you will get a better seal and be much happier with the sound. I havent used it for more than an hour. The included loop and hook weren?t so useful, I?m sure it?s good enough for hanging them but I didn?t brave clipping the £249 headphones onto something and hoping they?d stay put!
