Hi Don: MANY thanks for your valuable input. Do you get much/if any audience comments about using them? What brand/model do you recommend? At $10, it's certainly worth a shot to see if this setup is a feasible alternative to relying on 'built in' speakers for performance monitoring. If I do end up purchasing the Tyros (seems more likely by the day) being able to monitor thru tiny ear buds would certainly beat having to purchase & drag along the Tyros speaker system including sub woofer too. If I get the Tyros, I'd proably pass on the Tyros Stand and speaker - sub woofer system, unless someone here convinces me otherwise.
