Pros: Neutral across the hearing range; Comfortable adjustable headband; Detachable cable
Cons: Open-back may leak a lot of sound, so not ideal for travel.
These have nice dynamics and are flatter than some headphones. Despite that the low-end still has enough gusto to bring tracks to life. Another benefit is the detachable cable which uses a 5N OFC (99.999%) make-up meaning the likelihood of internal corrosion is reduced further. As this cable is long and the headphones uses open back means they may not be ideal for travel situations like the bus or train.
To be honest, whilst these won't replace a good pair of Sennheiser, Grado, AKG, Shure or Audio Technica headphones they do a fairly decent job in my opinion.
They use a 32 ohm impedance although I don't know how much power or the actual sensitivity although I suspect it to be <100dB SPL due to the gain required on my headphone amplifier to gain an average listening level.
