Sony MDR MA 900 (new release from Sony) - Page 7

post #91 of 767

Been looking at some of sony's older headphone models which I've seen briefly mentioned around here. Namely the SA5000 and the Qualia 010. Man they look Amazing!basshead.gif

 

Really wish sony had gone in that direction in terms of design, rather than the simple and completely undramaticle (yes I just made up a new word) look of this one.

Sorry, for some strange reason, I'm not subscribed to this thread despite me posting to it. I didn't see your message.

 

The next time I head to Fujiya Avic, I'll give that a shot again. But as mentioned, being a pair of open headphones and in a busy shop, it's gonna be hard to make a decent call on it's sound stage.

Oh that's fantastic. That completely instills my confidence in their webshop. Thanks for shedding light on that; was wondering why Amazon and J&R keep saying "four to six weeks" and Sony is sitting there promising them to ship within 24 hours.

I have an account with Sony and it looks like they are good to ship the MA 900. I did everything but complete the order, and it indicated it would ship 4/18/2012. Having bought electronics from the Sony website in the past, I can substantiate that it does what it says it will do. I think if you want them, the MA 900s could be bought today.

I had the chance to audition these a while back, some weeks ago. It was at a electronic expo/fair, so it was quite noisy. So I won't say anything about their sound (I didn't like it TBH, but as said, it was noisy..).

 

They do feel very cheap though. Very plasticky and cheapish feel to them. It didn't feel like $300 headphones I was holding. They were comfortable but all that plastic, and the headband in particular, was a real turn-off for me. Normally I'd say that my Denons are the headphones I wouldn't want to drop on the floor. The Denons feel like they are built like a tank in comparison to these Sonys.

[note: I know very little physics, so these could be dumb questions].

 

 


Dual drivers is a good idea, but the reason it's easier to do with IEM's is because the drivers are smaller, and they can fit multiple drivers.  It's hard to fit 2 drivers into a headphone that would be practical, and then there could be issues of them being to close to your ear for the 2 drivers to have a very coherent sound.  Speakers get all that air between you and the driver.  Still it's something I'd really like to see.  AKG was fairly successful with it in the early 80's, so with new technology and new designs, I'm sure it could be made to work better than that today. 

 

But bigger drivers isn't really what we want.  Bigger doens't address the real problems headphones have.  We don't need moar bass.  We need less resonance artifacts, and bigger drivers are just going to make that worse AFAIK because they will be less rigid, and more prone to breaking up and getting funky.  If they can't do it with a small driver (which every company has shown they can't), then the last thing I want to see is bigger drivers with cheaper materials.  I would say it's probably akin to why insects can only be a certain size because of their exoskeleton. 

 

Better they try to get what they're currently using to work well.  IMO big drivers is just a marketing gimmick like megapixel numbers often are for cameras.  Moar megapixels does not make a bettter looking image.

I mostly agree with that.  A little nitpicking though...

 

1) Clean bass at high SPLs is always nice and bigger drivers, up to the limit of what can be strapped to a person's head at least, help with that.

 

2) The size of insects and other arthropods is limited by the oxygen content in the atmosphere because of the way they breathe and not their exoskeleton.  When oxygen levels were higher there used to be some pretty monstrous bugs.

 

Arthropleura, giant centipede.

I agree that clean, deep bass is nice, but it's hardly the priority considering the serious problems headphones have and the fact that a large driver is likely going to make it worse... unless they do something about that like the ring radiator Sennheiser came up with.  I'm no expert on driver tech, but it seems like a marketing gimmick to me. 

 

Interesting about the bugs!  I was told that insects are limited by their exoskeletons when I was in Ecuador and the locals were telling tales of seeing HUGE tarantulas.  An American claimed it was impossible due to these skelatal limitations.  But I wonder if oxygen levels are higher in a thick rich forest like that...  scary

And food abundance.  As species increase their success the available pool of resources declines for less successful and inefficient designs.  Precisely why the smaller insects basically rule the Earth and will continue to do so.

Though bass is prominent in many phones these days, Sony's had the inverse problem w/ it's higher end phones in the past.  Seriously, the SA5000 only has upper midbass and goes off a cliff.  Everything below that is pretty much missing in action.  One reason 70mm might be a good idea.  Still not the best material though.  I hope they will translate to a SA5000 replacement.  I don't think Sony has the coffers left to shoot any higher.

Exoskeletons are also a limitation in arthropod size and those that Anax mentioned also apply to all other land animals too so they're not worth mentioning when limiting yourself to just bugs.  AKIF, given current conditions, getting enough oxygen through their spiracles or whatever is the first problem they run into as size increases.  At least without growing lungs or some better way to extract oxygen from the atmosphere instead.

 

On the headphones, the MA900's are most likely going with the large drivers and bass lens just get back to a neutral amount of bass from all the losses caused by the extremely open design.  If it doesn't have any terrible ringing it might turn out to be a good idea.

Hmm...Biology thread?

I just looked it up and what are commonly known as "trees" are actually a polyphyletic (i.e. artificial) grouping.  Definitions of "wood" also appear similarly vague so I'm not seeing much of a reason to exclude bamboo myself.

 

Also, in case you didn't know, cladistics is fun!

 

I read somewhere that the R10 bio-cellulose drivers were grown with special bacteria and that the process had a 90% failure rate.  Anyone know if that's actually true?

I saw 5 new notifications, I thought maybe somebody had finally got a hold of these and posted a review. Am I in the wrong thread?rolleyes.gif

post #104 of 767

I've heard the same about the R10, but I've never heard it confirmed by anything I'd consider reputable (like say, Sony). I've also read about increasing failure rates on the drivers as time marches forward, but again, never confirmed.

Here ya go, back on track:

 

I can't wait for [insert random new headphone here] to come out!  It's got such a shiny headband!  But I do wonder about the quality of the plastic and how people will think of me when i'm wearing them.  I bet [insert meaningless marketing BS] is going to sound amazing.  The [insert random decades old technology] looks awesome!
