What’s a good amp

For PS4 if your headset needs a bit more power? I need the mic to work as well. Also I was thinking of going this route http://ift.tt/2fDyES6 but I don’t know if it’ll let the mic work or even if the PS4 would work with that amp. Then I saw this, may give it a try http://ift.tt/2xEL8zX

But it offered no information about how much of an amp boost it will give. The headset I am trying to drive is 65 impedance.
