All this depends on the size of the model you buy, quite frankly. Some models out there will be designed to fit several head sizes from children to teenagers. Meanwhile, others will be optimized for much younger users. Even with some of the options presented on this list, there have been reports of previous buyers comfortably wearing them. In all reality, these types of headphones are not going to be optimized for sound quality and functionality, though. So, unless you literally could care less about that kind of stuff, it would be wise to shop for your own pair anyway.
