5.0 out of 5 stars Superb Sound Quality!, March 13, 2005

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 The Bose's dynamica range (they do NOT publish it by the way) sounds much much less, much details from the piano and orchestra music is missing and there is a lot of blank noise when there is no output from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One big problem I have with Bose is that they do not publish their technical data besides weight and dimension.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.

4.0 out of 5 stars GREAT CANS BUT A TAD EXPENSIVE, September 16, 2005

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.

5.0 out of 5 stars Top quality headphones from Sony, July 2, 2005

This review is from: Sony MDR-7509 Professional Studio Monitor Stereo Headphone MDR-7509 (Electronics)

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.
