I have some Beyerdynamic DT770s, but after long periods of use my ears begin to feel uncomfortable.  I want to deepen the depth by an extra third to avoid my ears touching inside.  Does anyone actually specialize in custom pads that I could go to online (or in stores)? 

So these headphones are extremely comfortable except for the fact my right ear slightly touches the inside of the speaker.  And I mean it hardly touches.  But, it becomes really uncomfortable over extended use. Is there any way to deepen the ear pad?   I've seen a picture of using cotton on...

I've been researching for a few weeks and choosing a specific headphone is really more than I ever imagined.  In fact, this whole audiophile thing has got me obsessed with reading reviews/comparing constantly like its becoming unhealthy, hehe.    Anyway,  I'm looking for a headphone/headset...

As the title says, would I need an additional amp/dac for any DT880 in 32, 250 or 600 ohms for strictly gaming?  I have an ASUS Xonar Essence STX which says it powers up to 600 ohms with its built in amp.  How much truth there is to this, I'm not sure.  To put it fairly, I'm an audiophile noob...
