I use PortaPros with my Traveler bass and love ‘em. Great headphones.I wish I got into using headphones when I was younger. I'd probably be a better player because of it (for various reasons).
One pair of headphones under $99 that I would recommend to ANYONE looking for a pair of cans is the Grado SR60i. They used to be like $60 but not sure about now. Those are some seriously do it all headphones that sound good if you're not too much of a bass fiend. Kind of a jack of all trades, master of none.
They're still my daily drivers, tho I enjoy Koss Porta Pro on ears around the house and they sound alright on my laptop, I may try with my interface while playing.
