Hi guys, I've been haunting many threads trying to find some good suggestions on my own and just haven't been able to get any solid answers. I love the warmth and bass thump of the Porta Pros, and the treble roll off is perfect for me, I'm pretty sensitive to treble. I love that sound signature, and I'm trying to find something closed back that I can use for traveling, that will give me enough isolation to use on a plane. Trying to stay under $200, but if you've got recommendations that cost more, go ahead and send them my way! Any suggestions are be extremely appreciated!
