Summary: I purchased the MA900s to go along with my AKG K702 65 Anniversaries, as I wanted a headphone which didn't require amping and would be a little more musical with synths (AKGs tend to be too honest and 2D and untextured sounding with electronic and synthesized bass, and prefer instruments more).
Pros: lightweight, iPhone case-friendly jack, easy to drive, neutral, mid bass, soft treble; airy, musical mids; good soundstage, good with synths
Cons: skinny, non-detachable cable; slightly floppy (has lots of magnesium though), sub bass, initial ear pad comfort, sometimes shouty upper mid range
Summary: Ill make this short and to the point.
The MDR MA900 is a fantastic headphone and even fantasticererer at the price of $200. The soundstage is just unbelievable, trumping cans that cost more than twice it's price (HD650, HD600, DT880). The imaging is also great, and the best thing about the soundstage is how focused it is. Neither the vocals, nor the bass are lost in this soundstage (amazing!).
Let's take a break from the sound.
Summary: SONY MPR-MA900
At $200-300 they are a steal. They are competing against the much more expensive high-end variants and partly excel at it. Overall, you cannot go wrong with these headphones – 10/10.
I have analyzed these using my laptop, connected to Audioengine D1 DAC/amp, listening to everything from piano concertos and symphonies to hip-hop. The bass goes deep and can be strong when needed without influencing the middle.
Pros: Detailed and musical, airy mid and treble, terrific soundstage, comfortable.
Summary: Along with the summary below, I have posted a comparison review of the MA900, Audio Technica AD900X and AD1000X here:
I've also got a youtube review of the MA900. If you like the video check out my channel for more reviews :)
The build of the MA900 is interesting. The headphone feels very light weight and almost flimsy in the hand.
Pros: Supremely comfortable, light weight, natural laid back sound, wide soundstage
Cons: Lacks a little sparkle, bass slam could be tighter, flimsy feeling build
Summary: The MA900 is “less headphone & more music”. The build is sparse, minimalist and does raise some doubts about durability. The magnesium alloy frame is the backbone holding the plastic enclosed lollipop drivers. The cable is nothing special and I never had issues with tangling. This headphone may not rank high on the build category but remember that it well makes up for it in comfort.The clamping force is delicate, but the headphone sits comfortably on the head – the 70mm...
Pros: A polite but engaging presentation, easy to drive, comfort, soundstage, great price!
Summary: Wow, i am soundwhoring in fps games now, i feel more aware of suroundings, and enemies steps distance, you can easily say the difference between some slightly cheaper and very cheap headphones!!! Had senn's HD429 + 558 + 598 open backs, and akg 550 closed backs before, oh man, sony are better in soundstage among them all, not sure by what margin, i'm not audiophile, but since i've started checking more expensive headphones like sens 5xx series, akg, i can tell the...
Pros: Very nice with instrumental music (violin, guitar), modern jazz, classical, psych/stoner rock. Epic soundstage in fps games (quake live, cs: go)
Cons: Could be better with some other than instrumental progressive metal music. You can hear distortion on high volumes (80<) in windows 7
Summary: Weil der Tragekomfort meines AKG 701 mir des öfteren Probleme bereitet (er drückt halt bei längerem Tragen auf dem Kopf), habe ich mir den Sony MDR-MA900 zugelegt. Sein Tragekomfort (und nicht nur der) wird in Rezensionen besonders hervorgehoben. Nachdem ich den Kopfhörer nun zwei Monate nutze, kann ich dies nur bestätigen. Es macht immer wieder Spaß, diesen filigranen optisch ansprechenden Kopfhörer aufzusetzen und mit ihm längere Zeit Musik zu hören.
Summary: I bought this headphone after reading many positive reviews about it and I can confirm it is absolutely fantastic. The sound is full of details but still very easy-listening. I don't think you can find anything sounding better than the MDR-MA900 at this price tag, or even close. Positive: - sound full of details and still very "easy-listening" - excellent "imaging" making these perfect for gaming - lightness Negative: - flimsy headphones, shall be treated with care and...
Summary: I have an Audio Technica ATH-M50 and ATH-M35, for which I have high regards. These headphones blow both of them out of the water. Vocals are far better than either. The soundstage feels far more wider than the M50. It is also insanely comfortable. My ears never get sweaty or complain. Bass is also quite good for an open headphone. The only negatives are that it feels a bit delicate, particularly the "bass lens".
