I want Dolby Headphone for consoles.
Ear Force DSS (first version) 65€
Astro Mixamp 135€
Ear Force DSS2 (50€)
DSS2 is out of the question if you want Dolby Headphone, as the DSS2 doesn't have it.
I use a external USB mic with PS4 so i don't need mic input in the decoder, is the first DSS quality as good as Astro Mixamp??? (it's half the price)
Yes, the quality is the same.
Do i need an amp or something with those devices and Sony MDR-MA900?
Not really. You can add one if you want, but the MA900 isn't hard to drive.
Can the Ear Force be used in PC for DH?
Yes, but only if your PC can output + encode a Dolby Digital live 5.1 signal via optical and feed it to the DSS. Forget about trying plugging the DSS into the PC with the USB port, as that won't work at all.
