Ohhhh Myyyyy Garsh!!!!!!
So I've been burning in my rx900's for almost 48 hrs now. I fetched my leftover acoustic foam out from the closet and cut out a couple square pieces and fashioned them into donuts with my scissors. Was much easier than I thought, no re-do's.
Let me tell you...these no longer have the $55 sound that came out of the box. They are easily a $150 pair of cans now. It's as if they mutated from being fed pink noise in two nights. If anyone is doubtful about burn in 'myths', do a blind test with these, truly. I would venture to say it would be an inexpensive test
Everything has opened up, mostly for the better. Music is a little bit more airy now and there is separation now where it was completely absent before...literally. The 1 dimensional muddy sound that came out of the box is completely absent. Bass definitely is the weakness though. It's not yet controlled as much as I would like. Everything else is good. Very nice mids and highs. Cool thing was while listening to Norah Jones' "Young Blood", I was able to pick up the mic feed when it was turned on in the beginning of the song. Pretty bad ass.
There are a few cons though.
- After the foam mod, it is a bit tighter around my melon. More so than I'd like. But, I'll suffer through it as I'd rather take the better SQ any day of the week.
- The bass....fart cannon comes to mind. A lot of the low end is drowned out bigtime by cavernous fart projectiles. That's all there is to it. BUT...there's a dampening mod here on the forums that I'm going to do to try and tame that wicked beast. We'll see how that goes.
-Oddly enough, they don't sound too good on a standard DAP (ipod, iriver, Macbook pro) or any source that wasn't amped properly. They shined ONLY when I hooked them up to my s:flo2, nuforce and my NAD. Actually, they sound best on my sflo2 by a noticeable amount. Really controlled, good detail/separation, and the drowny bass is a bit tighter. So a good/decent amp is a must if you want to suck out the best from these phones.
Compared to my d2000's, they are airy and spacious where the d2000's are not (much). This should be no surprise though, considering that the d2000 is closed while the rx900's are semi open. Cool thing about the 900's are that they have a bit of a closed headphone feel too.
I think after the burn in and modding, these cans would be great for leisurely listening, gaming and watching movies. They are not up to par for critical listening, but I think they are an amazing beginner purchase for anyone wanting to get into audiophile territory.
I'm gonna go burn them in for another 40 hrs or so...we'll see what happens
