They are open back headphones, won't this create a LOT of feedback?

I have returned as promised! I haven't given it the chance to burn yet but as soon as I turned on the DB gain on my STX, I was blown away by the quality and sound, many thanks this was worth every penny. My siberias will probably collect dust while im not in a chat with someone

Just ordered in the HE-400, will keep you guys updated, although mind you it will take a week to arrive.

I have done my googling and well I'm fairly new to the whole being an audiophile..   I tried googling up the loudest but I just couldn't find what I wanted so I decided to register on here as these forums kept coming up.   That being said, some background:   I use VLC and network stream...
