Whoa. Got off the screen (careful but it comes easy once you get how it fits) and treated the backside. The driver itself is mounted on plastic, so it needs some treatment. The wires are so frail I never want to open them up again unless there is an absolute need.
Pic 1: Outer shell; Pic 2: Screen - both all metal.
Note: pic with dynamat reflects a mistake I've been making for about 3 months - the metal backing of the dynamat has to be on it to work. HD-600, HE5SE, and these have to be corrected !!
Great.... so?
Mids are much sweeter - esp female vocals. Treble softer, and overtones more obvious/true. Upper bass might still has some veiling - need more time to be sure. Soundstage much taller, hearing distinctly more cues from the rear of the Hall or recording room - like an unusual amount for a can I would say overall has less than average sound staging. Still - staging not as good as say HE-500. Added note: I'm using MrSpeakers Ether Angled pads - much better than stock - sticking on by gravity.
Dunno if this is really an ERA-1 - it is now mid centric. I do know I'd rather listen to these than the Sundara or either Aeon any day, any time.
I think Brainwavz has a real winner here (or the manufacturer), the build quality is excellent, they just need to make them truly open, and not faux open.
Next step: 50 more hours break-in w/ no listening. Then spend lots of time with my 3 refs at least 5 hours each. Then 20+ hours on the Alara so I can write an actual review - not a string of observations.
I paid $339.15 for these, good buy.
