I just got these in the mail and I can confirm that the foamies from the JVC Marshmallows fit the Nuforce NE-7m with minimal effort. It's an almost perfect fit, snug but hardly ill fitting, and you can find Marshmallows on sale on Ebay for 6 dollars these days. I may not even need to use the Comply T400's that are coming to me tomorrow. I'll post pictures as soon as I find the battery charger for my camera.
I've only listened to them for an hour after burning them in for 6 hours with pink noise at work after receiving them, but I can definitely say that these IEMs beat the Denon C700s I used to have, having more of a kick and keeping up better with fast music, and approach the bass level of the Atrio M5 but with superior clarity. They have a warm detailed sound that really makes me enjoy my music. I haven't listened to as many headphones as some of the other senior members, but I can already tell that these are the best headphones I've ever owned. I've listened to them on my Touch 2G, my backup 2gig Clip, and the USB DAC on my laptop and I absolutely love the SQ. I wish I had known about these before wasting my time on the Denons!
The only complaint I have is that the headphone jack is a tad stiff in terms of flex at the stress point, worrying me about a possible snap, and the cable separator at the Y point is unnecessarily large and wide. However, these are mild complaints, as the build quality is overall sturdier than I thought it would be, and I can see these little guys lasting me a long time. Well done, Nuforce!
