    Sony MDR-7520 reviews

    MDR-7520 Professional Studio Headphones is rated 4.8 out of 5 by 46.
    Rated 4 out of 5 by from Sonically awesome, comfortable, but one big flaw I love these headphones, they barely leak and are surprizingly comparable to the HD 600 that are priced similarly but are less versatile. I havent had any problem wearing these all day either, they're built much better than the older 7506 and v6's with, obviously justifying the price point far nicer materials. There is one big caveat to this headphone though, the arm that holds the earcups. The joint on each side of each earcup squeak at every slow movements, especially the right one, and its starting to aggravate me after a couple of days. It's probably an easy fix, just a bit of silicone lubricant, but it's a pretty bad design flaw for a headphone in this price range.

    Rated 3 out of 5 by from Great Sound but Mechanically Noisy As a looong time Sony headphone user for location film sound and studio voiceover, I have used the 7506, the 7509, and splurged on these 7520. The sound is accurate, full, and terrific. Best I have ever owned. BUT...I record audiobooks and have found these make a lot of mechanical, plastic-on-plastic noises as I move my head...or even just my jaw...and the mic picks it up, necessitating pickups and editing. Clicks and clunks as I speak. Have tried and continue to try lubricants to the joints to reduce it but have not found the magic formula yet. So while they sound great, they are not working out well for that close-to-the-mic in a perfectly quiet studio application.

    Rated 5 out of 5 by from These phones are great I have MDR 7509 HD which are very good, but the 7520 model is much more accurate and balanced. There is excellent detail without being edgy, and their bass is deeper and cleaner than the 7509 HD. Some folks believe that lots of bass is good, many headphones have bass response that is boomy, but these have accurate bass as well as midrange. I do a lot of 'on location' recording so my reference is classical and jazz live music, and these headphones are the best available. Some people prefer a particular 'sound' in their headphones, and there are lots of choices for those people. If you want accurate, natural, sound then these are for you.

    Rated 3 out of 5 by from They sound beautiful. But the creaking is absurd. The audio is fantastic! I do love listening to these. I am sibilant sensitive and these have fantastic clear highs. Bass is controlled, powerful, and honest. Midrange is full and does not get influenced by highs or lows... I reach for these more than my other headphones.� That being said the creaking and squeaking that these headphones have, is maddening. Right cup is worse than the left. But they both have a loud creaking sound if you chew, yawn, turn your head, or move around.. I have looked over it for a while, cause I thought it would settle down over time. But it has not. And possibly has even gotten worse over the three months I have owned them.� Audio is truly great though... No like really great!

    Rated 5 out of 5 by from Fantastic Headphones For Monitoring I personally use this product for monitoring my guitars while recording in my home studio. The main reason I purchased this was because a few of my friends who do a lot of studio work use them and swear by the for being some of the most neutral sounding over-ear headphones they have ever used. I can honestly say that they were right on the money. These Sony MDR-7520 headphones blow my Sennheiser HD280 Pros out of the water, and I swore by the Sennheisers for years. I honestly can't say that there is much that isn't so great about this product because it truly has knocked my socks off.

    Rated 5 out of 5 by from So many people couldn't be wrong These are really great headphones, and I own (and have owned) lots, both cheaper and more expensive ones. Balanced, with great detail and clarity, tight but powerful bass that doesn't bleed the mids and a decent scene for a closed can. You can't ask for more. They are also good rounders and sound good with everything and maybe they will improve even more with time. I read many reviews before buying them and I'm so glad I did as now I can add to those great opinions. The only snag for me would be the cable, being coiled is a bit heavy on the go, but I think it's easily replaceable for a straight and shorter one (at this price, it should have been added to the package).

    Rated 5 out of 5 by from Outstanding out of the box Critical listening, audio production. I own Sennheiser HD650's which I love, but can't always use due to their open design in my home studio for isolation purposes. These fit the bill nicely. They're not completely burned in, but even out of the box they sound great. Highly responsive bass, intelligible mids and crisp highs. I love them. They're also comfy and have the perfect length removable cable. I use them with my CEntrance DACport headphone amp.

    Rated 5 out of 5 by from MDR 7520 and MDR 7509HD I am a classical musician who records in concert halls- mostly chamber music (piano, brass, strings, percussion). I have always used Sony headphones when I engineer and produce, although I have tried out a number of other brands (Sennheiser, Grado). I would be the first to say that headphone sound, like speaker sound, is a personal choice, so read on with a grain of salt. I was looking to upgrade my headphones and decided to try out a few pairs. After some research I focused in on the Sony MDR 7520 and the Sony MDR 7509HD. I am thrilled with both. They are clean, accurate and present in terms of sound. I can hear lots of detail in the variety of musical ensembles I have recorded, however it is a pure sound, uncolored and true to what you would hear live. I should also add that I use a variety of microphones, but stear mostly towards the Earthworks omnis- mics known for their true sound, no coloration- they pick up just about exactly what you hear- great for recording classical music in a hall. The Earthworks/Sony combo feels like a great pairing. The 7520 and 7509HD are both excellent phones for producing, engineering and editing- you get an incredibly true sense of what is being recorded. For kicks I tried these headphones out on my stereo system listening to mastered and released recordings- the sound was as you would expect- very present, somewhat bright, almost too clear for casual listening- you get the detail that you hope for when recording and none of the coloration. I then went back to my pre-mastered Pro Tools sessions and listened with both pairs (7520 and 7509) and made the realization of why these are such great studio headphones- clarity and accuracy of sound, perfect for hearing what you are recording. They no longer sounded bright like they did on my stereo- they just sounded true. If I had to compare these two headphones, the listening I did on my stereo of mastered recordings sort of helped in the distinguishing of each- the 7520's felt brighter than the 7509HD on released recordings, which made me think I preferred the 7509HD; but when I went back to listening in Pro Tools I found the 7520's to have a bit more clarity and detail. This was a very slight difference, but a difference none the less. Kind of like going from 11 point font to 12 point font (not a big deal to read 11 point font on its own, but when you compare it side by side with 12 point, there IS a difference- each will do just fine, but why not go with more detail if you can get it). I decided to keep both, since I usually have a need for at least two pairs of headphones at recording sessions- might as well have a choice. The only negative I found was that the 7509HD made a little bit of noise if my head position changed while listening- since they fold for storage, the hinges have some give, thus creating a little bit of sound when you move slightly- not a huge deal, but when you are listening with a fine tooth comb for any and all sounds in the mix, you want the phones to be snug and quiet. The 7520's don't make ANY extraneous sounds. Both headphones fit well, are comfy and look fantastic- the 7520's have an especially smooth, simple design- very sharp aesthetically. I'd say that even though the 7509's move a bit when on, they are likely to be the more comfortable of the two for most people- bigger ear pads, larger cup around your ear, less gripping on your head; but having said that, the 7520's still feel great when on. I would say, and this is typical with any Professional level Sony headphone, you're money is well spent on either of these. I am very happy with my purchase (of course, I did end up keeping both).
