Pros - Bass response, frequency balance, uniqueness
Cons - Comfort of provided pads
The FA-011 LEs are an upgraded version of the well known FA-011s. They are made using exotic timber cups with just 10 units made per timber for a total of 40 units ever made worldwide.
The LEs include a passive frequency filter called the APE-03 which makes an amazingly flat frequency response while keeping the bass response that the FA-011s are renowned for.
The ear pads provided with the LEs aren't thick enough for me and left my ears pressing against the inside of the headphones, but this was easily fixed by exchanging the pads for a set from the stock FA-011s which compeletely fixed the comfort.
The staging isn't as big as the HD650s, but the detail and resolution is better. The LEs are an outstanding headphone for people who like clarity without losing bass impact and presence. They're also very good for gaming.
Great headphone - see if you can get your hands on a set before they're all gone!
