I (see)hear(YouTube) reviews of supposedly what a keyboard sounds like.

If a keyboard doesn’t have speakers, aren’t we really evaluating the external speakers the keyboard is using; more than the actual sound of the keyboard itself?

Seems to me, it would be better to purchase the best set of headphones available to actually hear what the keyboard sounds like.

Then go out and try to find speakers that best reproduced what is heard through the headset?
