Been away a long time, and just dropped into head-fi to check out the shure line up. I like the look of 425s (yes call me shallow) haha so I wanted to do some research.
Here is a nice youtube vid comparing the 535 and the 425 at CES. Some good descriptors there - but of course could be BS as it is coming from a shure rep.
Have always been a big fan of the shure 500s etc, so it is nice to see some advancements!
