1" extra room lengthwise in my usual size (way too big). What a difference this item can make to a kitchen, laundry or work room. My insomnia was really acting up so it took a number of hours to get to sleep, but eventually I did. Ill keep them. Gorgeous material. (off, ANC, Amb) so you dont need to have app/phone all the time. The built-in microphone and switch are a plus over similarly-priced headphones lacking this feature. I have used it in mildly windy parts of Himalayas, works well. this product is overpriced in my opinion. It fit true to size (for reference, he?s starting to fit into 24m at Carter?s).
