Should be okay, the frequency is fine. But as we've stated alot of times it's not recommended to use ultrasonic on headphones.
It is too easy to mess up the volume, if it's too high it may damage your hearing or too low and you may not get results. With ultrasonic since it's silent it's hard to know with headphones.
