I do like lower tones and typically use 915/1085 which is less fatiguing
over long periods. OTOH, their TX audio harmonic is still within the normal
2 kHz bandwidth for SSB transmitters when transmitting AFSK. Not a problem
for those of us using FSK.
And not a problem if audio levels are set properly. There's an app note
on my website that describes several good ways to do it, depending on
what you have available to check it. Those instructions are on page 3.

While the document is mainly describing USB audio interfaces, setting
levels are the same if you're using the computer's built-in audio
interface.
