RH-50 are Roland's low-end studio monitor headphones. In spite of which they're quad-driver - they have dedicated tweeters which sound really smooth when the headphones are recabled. Great for saxophones and any treble-based delicate music. RH-50 are much like the K-240 with less detail and an even more raised midrange.
And AKG K-240 Studio are, well, what the name says - studio-standard headphones. Current generation (4th, 55-mm. diaphragms) is quite different from the original, if you want a suggestion, try to hunt down the original silver K-141 or K-240 Sextett (38 mm. diaphragms, K-240 are the circumaural version of K-141) and recable them, then give them a good amp.
You can mix in K-240 (many musicians mix/record in K-271, the closed variant), and frankly, the stock AKG cable is horrid. A replacement cable might cost almost as much as the headphones themselves, but it's worth it.

Finished with my woman 'cause she couldn't help me with my mind; People think I'm insane because I am frowning all the time. All day long I think of things but nothing seems to satisfy: Think I'll lose my mind if I don't find something to pacify.
Can you help me Occupy my brain? Oh yeah...
I need someone to show me the things in life that I can't find; I can't see the things that make true happiness, I must be blind...

Make a joke and I will sigh and you will laugh and I will cry, Happiness I cannot feel and love to me is so unreal.
And so as you hear these words telling you now of my state I tell you to enjoy life: I wish I could, but it's too late.
This is really just a TB-303 pattern with a delay on top and some filter knob tweaking. A musician friend said "congrats on your first acid track", but that's just what it is
