Sony MDR-7510 Professional Studio Headphones with 50mm Driver Unit

So i've had the Sony MDR-7510 for a few days now and have been so impressed by them that I decided to write a review. I hope if you are considering buying these headphones and have read this review, you find it helpful.

To test the MDR-7510 I will be using another great Sony product; the Sony CMT-SBT100B home audio system.
I decided to use some Master Quality Audio (MQA) live music to test the MDR-7510, played through Foobar2000.

Bass; very accurate! one of the most accurate i've heard from any headphone, regardless of price.
goes very low right down to 18-20Khz. the only other headphone I own that has lower/more accurate bass is the Denon AH-D5000. The Fostex TH-X00 Purpleheart which I also own goes low but it's bass is bloated in comparison to MDR-7510 and AH-D5000. Just like the AH-D5000, the MDR-7510's bass doesn't give any more than is needed, there's no excess. It is tight, accurate and goes very low. Also layers of detail, you can hear everything.

Midrange; Just perfect! It is not recessed, blends perfectly with the bass and treble. Very smooth, warm and lots of detail.

Treble; The treble is very fascinating, sometimes I think it is too bright/sharp and sibilant, but the more I listen, the more I realise that it's just the recording/music, as the sharpness/sibilance is not present in everything I listen to with it. It's just extremely honest and accurate.

Soundstage; very good soundstage, this is where they remind me of my Ultrasone Edition M headphones. Ultrasone are a company known for producing headphones with super realistic soundstage. So the MDR-7510 sharing some characteristics with Ultrasone headphones is a very good thing indeed. The only thing the Edition M does better is imaging, but that's not to say the MDR-7510 under-performs in this area. MDR-7510's imaging is very good,- Ultrasone Edtion M's imaging is outstanding.

Overall impression; very, very impressed by the Sony MDR7510 and it's ability to compete with much more expensive headphones, in all areas (sound quality, comfort, compatibility with amps etc etc). It's easily one of the most accurate headphones i've ever heard. Beaten only by Denon AH-D5000, AKG K702 (Austrian version) and Ultrason Edition M.

I´m professional live and studio engineer and i bought these one to try out if these could replace my trusty MDR-7506:s that are coming to the end of their lifespan.
 
Im always looking good and flat and detailed overallresponce, that is true to original signal and not hyped at any way. I also need headphones that are sturdy, comfy and dampens outside well.
I also need to play them LOUD in time to time, because i need to hear small details, in noisy places (as festivals, clubs and such)
 
In studio, i refer all of my other headphones to my Grado SP125: that are truly amazing and a way a bit dull headgears. And dull is a good thing, when you have to listen by profession and trust that what you are hearing, is all that there is. Grados are openback headphones, so they don´t compare straight to these Sonys, but thats what im after anyway. Older MDR 7506 are truly nice ones, with bass that is not very hyped at al, but goes really low. And there is not many annoying peaks or dips in frequency responce.
 
So what about these new 7510:s? Build quality seems to be very nice and sturdy, even that they are made of plastic. They are very comfy too. When you put them on, first impression is: Whoa! There is bass and its very punchy and detailed. Soundstage is nice and well controlled too. There are details in there ok, and you can hear everything just nice. Dynamics works well and stuf... But are these a bit dull sounding? Too nice? A bit honky at lo mids/upper bass?
So i grabbed my Grados and older Sonys to compare, and ouch! Everything sounds too bright and where did that bass go? ...Ah, this is just how it supposed to sound Hmm that says alot.
 
So, after hours of analytic listening i find that these are nice headphones if you are after for nice and punchy sound, not truefull monitor quality sound but still quite nice and detailed, these might be for you.
Everything sounds pleasant.
If only there would be less going on in 200-300hz and more on around 5 kilos, and slight shelve boost after 12kHz they were a way nicer headphones. Well. at least they are not harsh.
(And yes, you can Eq, them if you must. This worked for me with precise, neutral digi Eq: - 5,5db at 198Hz 0,64Q. -5,5db 290Hz 0,71Q. +4,5db 4050Hz 0,71Q and +5,5db at 12000Hz with modest shelve.)
 
I think that i´m just buying another pair of 7506:s They are not build as well as these one, they are a bit awkward and there are many not-so-good things on them, but they present way better and truefull sonalbalance to me. You know, if it sounds ****ty, i want to hear that too!
 
I think that i bring these ones to the studio, to the tracking room. I bet these works for the tracking drums and such brilliantly!
