Neither is a bass monster, but both go really low (no bass emphasis I can hear). Both detail well, W40>W4.
That's it for now, go for the dog walk/random iPod play walk...
Having read this in the morning, was the impetus for my visit to the local store today. Unfortunately they were closing up soon so I did not get to try out the W40 again, just more NAD time.
Having said that, I do believe that Westone have been very open about these being the same, using the same driver setup, tuning, etc.
The only other report apart from a very vague post on the new W-series thread seems to be from Headfonia and they're just really off more often than not so I take what they say with a truckload of salt.
I don't want to mention anything about the new MMCX cables because I don't want to touch the cable talk with a 20-foot pole, but I do want to ask a couple of things before I go in sometime next week.
1) Are the nozzles the same size/diameter (some of the photos I've seen floating around make them look slightly larger)?
2) Are you using the same tips on both of the 4 and the 40?
