I too just bought a pair of HD600's and the first thing I noticed is that the clamping force was way more than I thought it would be. I had to bend my metal parts on my HD600's too.  The HD598's are definitely more comfortable, but they are "close but no cigar" compared to the HD600 in sound...

You can get them from Amazon or from Sennheiser    http://www.amazon.com/Genuine-Replacement-Cushions-SENNHEISER-Headphones/dp/B002STGF6O

I know this is a year late, but the HD250-ii has a head band that is similar but with more cushioning. The HD250ii was a favorite with pilots because of the closed cans so they sold them a lot longer.  I was able to buy this part from Sennheiser a couple of years ago it came with the whole band...

The lower the impedance, specified in ohms, of the headphone the less power it takes to drive them.. Unless they are really inefficent which your Sonys are not.   Clark

The MDR-V300's are a 24 ohm headphone. The E6 should work fine.    For a plane ride try an IEM, in ear monitors, the kind that plug up your ear if you can stand that.   Clark

Too bad you couldn't review a Sony D-5 their first "portable" CD player Vintage 1984 or something , I used to have one, but sadly it died. It was great as long as it was plugged in to the AC dock. it could drive my 300 ohm Sennheiser phones as loud as you could stand. I never bought the battery...

Just a follow up. I finally received the 616! It doesent feel cheap at all. It has a really solid feel to it. I dont mind the use of plastic in cameras or DAPs, as long as they are designed right. there are no loose seams or flexing. This is designed right Clark Nothing that can...

have you tryied going to the Sennheiser site you can get rreplacement cables for these. the cable just plugs in to the ear piece Clark

Thanks to all who replied! I went ahead and ordered a NWZ-S616 after reading all the reviews and looking at some youtube videos, I felt ok buying this sight unseen or felt. I ordered it from Sony direct because I had a gift card. It was a little more then you can get it for online but not...

Just wondering if anybody had any impresions on the feel of the four way control pad for the 600 series? They look like the buttons on a microwave to me. I have not had a chance to play with one of these in a store that actualy worked. Most of the Big box places won't let you play with one...
