If you have an expectation of Audeze circumaural headphones that they are large and heavy and not something you'd want to schlep around, the LCD-1 is a mould-breaker
"More likely to be a concern for some are the smaller earpads, commensurate with the reduced capsule dimensions. The LCD-1 is a circumaural headphone, but like many others its earpads don't have a large enough opening to surround the entire ear – unless your lugs are notably dainty, that is."
"There's not much point making a foldable planar magnetic headphone for use in a wide range of applications if it has low sensitivity, so it's little surprise to find that the LCD-1 is not only the most sensitive Audeze model we've tested thus far, but also the most sensitive circumaural PM headphone from any manufacturer. Our measured 118.1dB SPL at 1kHz, averaged for the two capsules, is almost 3dB higher than we recorded from the EL-8 open-back [HFN Oct '15], so there's no question of any worthy headphone output providing sufficient voltage to drive the LCD-1 to high SPLs. But to achieve this Audeze has had to resort to unusually low impedance. It specifies a nominal 16ohm figure but we measured almost 3ohm lower, ranging from 13.1 to 13.3ohm across the audible frequency range."
