After 125 hours of burn in, I don't know, it feels like the highs have opened up, something that definitely was lacking before, they felt so "tamed" and veiled.
Guitar solos and most riffs sounded all right, but just boring, they had no edge to it.
I was actually EQing DOWN the bass, and the sub-bass up, along with the highs (2db up), after some high-volume burn-in (brain or physical) I just figured it didn't need any EQ anymore.
Anyways, just had my first wow moment with the re-400's.
Having had the ATH-M50s for a few years now, I was just listening to The Temple Of The King cover by Scorpions, and noticed how the bass on the RE-400 is so subtle compared to the M50s.
The notes on the intro sound so much livelier, the guitar has more "attack" and the bass gives a subtle reverberation on a couple of low-end notes of the guitar. It just sounds so much more dynamic.
This is the kind of detail the M50 would just not pick, simply passed over it, even on the bass department.
I guess the RE-400 just have a better dynamic-range and details compared to the M50s (specially because the M50s are mid-recessive).
Anyways, I really don't understand how people can tell the RE-400's are low/lighy on bass, they're definitely enough to me, even coming from the M50.
Haven't done any AB'ing with my Earsonics SM3, the cable is damaged (my dog screwed it up), so haven't listened to them for a while.
I just wish the RE-400s had a better cable, they appear really fragile.
Also, anyone else feels like they have a bump in the 4k range? Equalizing it down (slightly) makes vocals sound more natural, like removing a hiss around it.
