im a noob but can you tell me how does the amp really help besides the volume control ?
Gaming headsets/headphones = big no-no. People who recommend Astros don't know good quality.
Headphones from a good brand such as Sennheiser, Audio Technica, AKG, Grado, ect = Goooood. Very good.
My personal recommendation is a pair of Sennheiser HD555s and a Rolls amp. Good headphones usually require a decent amount of amplification to get the best out of them. 85 bucks is an insane price for those headphones. Heck even the refurbished price of 51 bucks is down right mind-blowing considering how good they are. The only downside is that they are "open" backed headphones which means they leak quite a lot of sound. If you need closed back then you can try the HD280s or search for headphones from another brand listed.
Remember that headphones never need surround sound nor will they ever. Headphones can emulate or trick our brains into thinking this with regular stereo sources. There was never a need for it as it was always there.
Things like onboard sound or TV outputs just add gain to the signal. That makes it loud, noisy, and you get dirty audio/distortion. Amperage is the actual power being sent to the headphones. Gain takes that very weak/small sound being sent and just increases the volume while sending little to no power at all. Good headphones have a higher impedience rating than lowly headphones or gaming headsets. Higher impedience = needs more power to drive them. You can use without an amp but it doesn't sound nearly as good.Thanks a lot for the response :D
