The closed headphone is REALLY impressive. It's more open sounding than the open headphone!! The two of them make a really nice matching set actually, with similar sound sigs. The closed one being more open sounding in the treble to my ears.
So it seems the M1000 = FA-003 and the M2000 = FA-002.
The M1000 or FA-0003 is terrific and I really like its evenness from top to bottom, so the Jaycar deal is a real bargain for the closed one. I don't think they do the open version, but imo, it's not quite as crystal as the FA-003.
Although FR graphs show a larger bass hump on the FA-003, it doesn't sound that way. Listening to mens' voices on it doesn't produce a bloom on their sound as so many headphones do. Bass response is really nice and treble is nicely defined without emphasis. Mine is working easily up to 15,000 (on a test with my ears which start to run out of steam any further up) and my daughter is easily picking up at 19,500 on them so they are well extended too.
Found a short cable too ....
