Im not an audiophile but to my amateur ears it was a very clear crisp sounds even at max volumes. After that it worked. Wide open would be so loud it would hurt. Bought 2 sets of these and love them. The pads are pretty big cover all your ear though sometimes you feel your bottom ear ending might get under the pad. Im a hairstylist, I stand at least 8-10 hours a day; the Skecher memory foam shoes are the only shoes that Ive ever worn to work that dont hurt my feet. This is a really good sized shoe racks! - Range Sonoro: 10 Hz - 39,800 kHz. The ear hooks are so soft and flimsy they won?t stay behind your ear. I have had the same sandals for over 8 years, wore them to work every day in the summer and they are still in good shape.
