output impedance vs impedance load

[wilkinsi]

Wired, my Roland VS recorder's headphone out has an output impedance of 22ohms but the recommended load imp. is 8-600ohms. I wanted to change my headphones but they seem to be available in 400ohm rates. So will it work properly?

Headphone amps are such low power that I wouldnt worry about it. Im sure someone will argue with this, but think of how many times your mp3 or cd player has been run without headphones and it still works.
