>>68008822>What advantage does the whole separate amp/expensive headphones thing do for you that makes it so much better than a usb headset
None has to exist. There are enough incompetent products that fit the description. The headphone and the general audio market is overcrowded with poorly performing products.
The acoustic goal of headphones is to be tuned with a flat sensitivity over the entire audible frequency range, plus or minus some factor of taste. The addition of other components, non-linear distortion, should be minimized. This is normally of secondary importance for headphones.
The electronics delivering the signal should provide enough voltage to play loudly enough, with as little noise and interference as possible. Non-linearity should be minimized, but this is suggested by having enough voltage.
Headphone sensitivity is the most important quality. If the relative sensitivity is imbalanced, such as too much low or high end, this can be compensated by using an equalizer.>that require more power to 'drive'
Maximum sensitivity to be usable with low-voltage consumer electronics is not the central priority for "audiophile" headphones.. A headphone's motor is usually most efficient when it is designed to be non-linear, not desirable for quality, though there are other factors.>what makes something like the 650 better? or the massdrop version
The HD 650/6XX is a simply constructed headphone that is easy to service. The response is fairly even over a wide frequency range, though it could stand to be improved a bit in the bass region. The high impedance means that even though its efficiency is average, the sensitivity is below average. A headphone amplifier may be useful to provide more voltage to the headphone.>highly dependent on the files you're playing. movies
Yes, but distinguish
-Container, such as digital artifacts from lossy compression
-Production, how the track was recorded, mixed, and so on
The better headphone makes the most tracks work well.
