I looked at the main categories and I don't know exactly where a Turtle Beach DSS it would fit is that an amplifier it's not a headphone. Its main purpose is to take a Dolby Digital signal through toslink and convert it to a 2-channel Dolby headphone mix. The only problem was it only works with Dolby language material Can anyone think of something similar to a Turtle Beach DSS for DTS and or lpcm surround audio signals? DTS would come in handy for about 65 to 70% of my blu rays,. And lpcm would come in real handy for Wii u and switch.
