Audeze LCD-2 by Lunatique
The LCD-2 is currently the best headphone I own, and I have quite a bit, not to mention have auditioned even more. To give this review a proper context, I'll need to list the other headphones I have so you understand what the LCD-2 is being judged against.
My other headphones are:
Stax 007MK2 (with Stax SRM-717 amp)
and my studio monitors are Klein+Hummel O300D's.
The best thing about the LCD-02 is its authoritative and deeply extended bass. It goes down all the way to 20Hz and remains pretty much ruler-flat from 1KHz to 20Hz--no irregular bumps or dips or roll-offs (many expensive speaker/sub systems can't pull this off). Its bass response is one of the very best in the history of headphones--accurate, tight, neutral, deeply extended, and powerful when required to be. It is also non-fatiguing, with a very full sound that's unlike any other headphone in existence (except the LCD-3, which costs twice as much). These are the most unique qualities of the LCD family sonic signature.
The upper-mids are a bit recessed (but very detailed), and some might want the treble to be a bit more airy (but plenty of people think its treble is perfect). I personally do EQ the LCD-2 so it's as close to ideal neutrality/accuracy as possible. If you want to learn how to properly EQ headphones, read this thread:

The main drawback of the LCD-2 is its weight. Some people think it's too heavy. I think it's fine, although it is certainly heavier than any headphone I've ever worn. Its stiff 1/4" instrument cables also bother some people, although you can buy third-party cables for it.
In conclusion, LCD-2 is one of the best sounding headphones on the market, and it has made a huge splash in the headphone enthusiast community (such as head-fi.org). It is considered a minor miracle because at less than $1,000, it is widely considered superior to many headphones that cost much more. No other headphones on the market does bass like the LCD family of headphones--not even the multi-thousand dollar super-high-end headphones like the Stax, Sennheiser, Beyerdynamic, Audio-Technica, Hifiman, Grado...etc flagships.
