The first SR-Λ (Lambda) series was introduced 30 years ago, and now the SR-507 has accomplished further evolution with its new sounding body (sound element).The conventional sound element has employed simplest structure so that as wide film diaphragm area as possible can be effectively used in comparison with its external size. Taking advantage of the conventional feature, the new sound element has been packaged in a tough resin case. Thus the new sound element has realized cleaner sound and more accurate sound image.

If the sound balance right out of the box isn't what you're looking for, (like the confuddled fellow who inexplicably gave these 3 stars), not to worry, they respond perfectly to an EQ, and will take on whatever sound signature you desire, at whatever volume (these sound just as good quiet or ear-bleedingly loud). Personally I like boosting 200hz ane below by 4db or so.
Most everyone talks about the mids or the highs, which are indeed world-class, and sharper and crisper even than any planar magnetic driver can manage. But for me (an EDM & hip-hop listener) the bass was the real revelation. Where even the best dynamic speakers produce a deep indistinct boominess, these can articulate the bass exactly, and you can suddenly tell the difference between a 20hz and a 22hz tone.
Even the sennheiser HD800 sounds slow and artificial sounding compared to the Stax. I haven't heard other electrostatic headphone systems (be it other Stax models, the Koss ESP950, or the absurd $10,000 Sennheiser HE50), but no dynamic, no planar magnetic driver can come close to doing what this Stax electrostat can.
Obviously your source matters, but even streaming soundcloud from the headphone jack on my phone sounds phenomenal through these. Using a hi-fi DAC such as the Mojo or GOV2+ is even better of course, but the gap between my phone (an LG V10 with a relatively great DAC to begin with) and those hi-fi dacs isn't nearly as great as the gap sounds when using regular headphones. I prefer a DAC that gives a lot of body to the music, such as the Hifiman HM601. Using a bright DAC might not be the best pairing.
While the astounding sound quality is the most important thing, I'd like to say a few words about build quality and comfort. The build quality is nothing special, they seem to be made of a cheap plastic, but I've learned that a cheap feel does not mean it's actually flimsy, but I baby mine anyway just in case. As these are the least portable headphone type on the market, that's not much of an issue. They will never leave the room where their amp is set up.
Comfort-wise, they are exceptionally comfortable. They weigh very little, and exert almost no clamping force on your head, but somehow they never slip off while you're wearing them either. The main issue related to comfort is the fact that they rely on static electricity to produce sound, and bumping your hand to the outside of the case can cause a quick grounding on that side, and you will only hear through the opposite side for a minute while it builds up a sufficient charge again. It's a minor issue that's inherent to the technology.
IN CONCLUSION, these are the best headphones I have ever heard, they put most $1,500 pairs to shame (ahem HD800 ahem), and if you know how to EQ for yourself, there is no reason you wouldn't be blown away too. No one who gives it a fair chance will ever give it less than 5 stars.
If you have not heard high end headphones before, I can tell you that you're going to be blown away by the sound. The Stax are so precise, however, that you're going to hear average musicians make one mistake after the other; you'll also hear the endless mistakes made by average music producers.
On the other hand, you'll hear producers like Gary Katx, and you'll be pretty much paralyzed by the beauty of the music. Katz produced a lot of Steeley Dan's music. SD used studio musicians, who are perfectionists, and the Stax will reveal how really good the music is.
I know there's a lot of money involved with the Lambda, but it will be more than worth it. Amazon has great pricing on the Stax--and other high end headphones. But I think it's necessary for you to find an store specializing in audiophile hardware, and listen to the Stax before buying them through Amazon. You may think that the 009s are worth the money, but listen first.
