Yes, a typical cheap pair of headphones will probably have a 20-18,000 hertz range and most over 10 bucks will list 20-22,000/24,000, although their REAL range will be much less. The average person in their 20's with good hearing (who didn't blow it listening to loud music in their bedroom or sitting in hours and hours of church) cannot hear above 16,000. They just can't.

There are a few VERY high end super tweeters a person can buy for their stereo's which can just reach 100,000 -but this it utterly ridiculous since NO music has content in that range and even if it did it is at the very highest end of what bats can hear (way beyond dogs!).
