I have firmware v5 and am wondering which EQ setting is the most neutral. I'm thinking its the 'Natural' setting. However, I find that 'Natural' setting does not sound that nice, lacks bass, and is rather flat. Which EQ setting do you prefer?

I need a set of headphones that will be used primarily at home (connected to either my laptop or my iPod Touch, Sandisk Clip+, or xDuoo X2). My first priority is sound quality.  Is it worth paying the extra $$ for the MDR-V6 or does the MDR-ZX600 offer comparable sound quality at a lower price?

I saw in the B&H Photo website that a new Sandisk product - the "Clip Jam" is coming soon.  The new product retails for $39.99 and all have 8 GB internal memory and are expandable to 32 GB with SD card.  Has anyone had a chance to try this new line of Clip players from Sandisk?  Do they offer...
