Hi. I'm hoping someone can help with my question. I've had the srh440s for 3 years now and 6 months ago I decided to attempt to improve the comfort of my phones. I added the head band padding from the hd650s as recommended (essential upgrade I've found) and replaced the stock pads with the 840 pads. Now I'm no audiophile but to me the sound quality of the phones was seriously compromised. I'd read so many comments saying how this was a must upgrade and in terms of comfort it's a huge improvement but the quality of sound is terrible compared to stock. I stuck with the 840 pads hoping I'd warm to the sound. Recently I'd been thinking about buying some new headphones (940s or momentums) but thought I'd switch the pads on my 440s back to stock. I instantly remembered why I loved the 440s. Now my question is are the 940 pads going to be any better than the 840 pads were? If the sound signature degrades as much as with the 840s pads I'll live with the less comfortable stock pads. If it's close to the stock I'm willing to give them a try.
Can't comment on the 940 pads but are you sure you got "real" 840 pads? I really like my 440 with the 840 pads so much more. It really removed all the things I didn't like about the 440 stock. But on the other hand, if you are happy with the stoke pads, why change? Just enjoy your music. No need to tinker if you love the sound. :)
