Well I received a brand spanking new pair of SE530 headphones yesterday via the mail. I sent them out to Shure on 5/14 and received the replacement pair on 5/22. I was jammin' to them on the way to work this morning.
Literally, brand new, with all accessories, box, paperwork...etc. So that's cool. I used the first metal box that the E500 came in for a little battery powered PIMETA I use at work/home. So now I have another....might put a little USB DAC in this one...we'll see.
During the week I was without them though I had the chance to listen to the new pair of Sennheiser PX100. Not bad at all, a great little portable headphone. While isolation was poor, it wasn't as bad as I thought and they did ok on the bus. I'll definitely keep them as a backup or for times when I don't want something in my ears (sometimes I just can't wear IEMs).
