 Superb Sound Quality!Mar 13, 2005
By Washington Heights
"Fort Tryon Park Cloisters"
I was looking to buy a good quality headset to hook up with Yahama P120 digital piano and Onkyo SR702 receiver. Someone recommended this headset to me. The sound quality is superb. SONY has detailed specifications on its dynamic range, response.
From my listening experience both from the Yamaha P120 digital piano as well as SACD played from SONY DVPNS775 via ONKYO SR702, the sound from this headset is amazing. I can hear all the details and nuances from piano music, orchestra work. For example, when in the first movement of Rachmaninov No 3, there is a very very "light and sutble" string accompaniment from th violins, I can hear that very very well on this headset. When there is no output from the Onkyo Receiver, there is NO blank noise at all.
I was considering to buy Bose QuietComfort II to upgrade my Bose QuietComfort I. I am happy that I bought this SONY. I compared the sound quality of this SONY MDR7509 with Bose QuietComfort I (not II, the new one), the sound quaility of SONY MDR7509 is way way better. The Bose's dynamica range (they do NOT publish it by the way) sounds much much less, much details from the piano and orchestra music is missing and there is a lot of blank noise when there is no output from the Onkyo receiver.
The shortcoming of SONY MDR7509 is that it is not as light weight and comfortable as the Bose QuietComfort I(not sure about II) and doesn't actively or eletronically cancels the enviromental noise. I really care about sound quality, SONY is superb in that respect.
One big problem I have with Bose is that they do not publish their technical data besides weight and dimension. When you call them to ask their frequency range, noise ratio, selectivity, they won't tell you. Instead they ask you to go their show room to try. In their show room, you will compare their products to nothing. And of course, they will most likely look good.

 GREAT CANS BUT A TAD EXPENSIVESep 16, 2005
By Thomas J. Stratford
I love to listen to headphones, and have been doing so since the mid 1960's. These Sony cans sound really nice, they have great seperation, and the dynamic range is quite good. They need to be powered by an amplifier, or receiver, they are not for low power portables, nor computer sound cards. I am listening to some newer country music, Shania Twain's "Come on Over". I recomend listening to female singers because their range is difficult to reproduce faithfully. These Sony's shine in the mid to lower base, and in seperation, but they lack the clarity in the mid highs around 8,000 hz where they tend to be a bit subdued, the highs are also some what muddy, but don't "zing" like my Beyerdynamics do. The other problem with the Sony MDR 7509 is the coiled wire which tends to tug at the phones, the limp wire used by other manufacturers is less obtrusive. The Sony MDR 7509 is a good pair of cans, if one listens to more bass intensive music, like rap, they however lack the clarity of my Sennheiser HD 580'S which are simply a better headphone at 1/2 the cost of the Sony MDR 7509 PRO.

Top quality headphones from SonyJul 03, 2005
By R. Nicholson
I purchased these headphones last week and have listened to a lot of both classical music and opera with them; its been a rewarding experience.
This unit has a full audio range while at the same time blocking out extraneous noise (however, they aren't a noise reduction unit) You have the feeling of almost like being in a sound proof room; you hear nothing but the music or ambient sounds associated with the orchestra. They were able to pick up some of the more subtle sounds that occur during a performance that you would not pick up from floor mounted speakers.
The only niggling complaint I have is that even though the set is circum-aural fitting, I found that they tended to be warm on the ears after about 20-30 minutes of use.
This product is expensive, but worth it, i.e. you get what you pay for; in this case, a quality product geared towards audiophiles.

Great cans for the moneyNov 30, 2005
By Rockin in the free world
I'm using these in my home recording studio, for tracking mostly. Any pro will tell you that you shouldn't monitor with headphones and these are no exception to that rule. For tracking though, these fit the bill nicely. Very comfy, thick pads that are shaped just right(for my ears anyhow) allow extended use. Good isolation and they're plenty loud. Decent spaciousness and sound stage.
Nitpicks: The bass seems exagerated, right in the "boomy" 125Hz range, it's not unpleasant, but it is noticable. My biggest gripe is the way the cord transmits sound into the headphones, like a stethoscope. Brush the cord with your arm and you hear it plain as day in the left can. Before I use them I have to make sure the cord isn't brushing up against or swinging into anything. I've noticed this sort of thing with other headphones to some degree, but it's especially noticable with the MDR-7509.
I'd also like to add that they're pretty well made. Mine have hit the floor countless times and are no worse for the wear.
For tracking in the studio or casual listening these are great for the money, but...Grado has released some great headphones in the $100~$200 range since I bought these, I highly recommend listening to some of those and see how they compare.

After 9 years, I still love these headphones.Sep 11, 2010
By Travis Funk
I bought my pair of MDR-7509s in the fall of 2001. I was a sophomore studying music recording and was told to purchase a pair of 'professional' headphones for editing. I opted to pay more for the 7509s over the 7506s that my classmates were buying because of several features. First, these cans go down to 5Hz. At that low frequency you're really 'hearing' with your skull more than your ears, but the fact that they could reproduce below 20Hz was important, because I do not like mixing with a subwoofer. Second, these headphones peak at 3W! They can get very loud, and being able to handle that much power is important for the larger drivers (7506 has 40mm while these are 50mm). During the first few years of ownership I watched as my classmates abused their 7506s, and most of them had broken. Later I became a studio tech and was constantly cursing the 7506s we used for tracking, as they were always breaking and I was the lucky one to repair them. After 9 years of ownership I've finally had to perform my first repair on mine: The cable had worn out on the 3.5mm plug, and sadly, I cut the nice threaded plug off and replaced it with a cheaper gold one. If I could have found a threaded 3.5mm jack to solder on, I'd have been happier. Unfortunately, repairing that Sony 3.5mm threaded plug is nearly impossible as they glue the whole assembly together and you have to destroy it just to get it apart.
The sound of the 7509 is great- very flat, but still full. I've tried many other headphones over the years, and the only runner up so far is the MDR-7506. Beyerdynamic makes great headphones, but they do not get nearly loud enough for tracking. AKG's 'pro' cans are junk and are constantly falling apart. Sennheisers aren't bad, but I've not tried any with large diaphragms. Every time I've ever used a lesser pair of headphones over the years, I've wished that I had these with me.
From what I've read, it sounds like the newer 7509HD model is not as good as these are, which is disappointing. If I had the money I would buy 5 more pairs for my recording studio. I hope I can keep these going for the next 25 years.
