Hi again, Skipjack.
Take a look HERE , the price for these earphones is acceptable. Moreover, in the square field on the right you will find the Behringer HA4700 headphone amp, which will supply more than enough power for you to listen at your instrument, and can easily mix another line (monitor from the main deck) to listen to the complete mixdown. And yes, Jess is right, you have to take care to spikes, pops and feedbacks... well, this is a start. Things can be improved.

Ciao.
