If you're playing on a modern console, I found a Turtle Beach X41 works fine. It takes a Toislink output from systems as old as PS2 and Original Xbox and converts native unfiltered Dolby 5.1 into Dolby Headphones, which is a 2-track headphone version of Surround Sound. It works just as well in DVD, HD DVD, Blu Ray, 3D, and 4k Players.
On consoles starting with the Xbox 360, you can choose to either "keep native" or engage Dolby Surround mode which converts DTS in to Dolby for those Turtle Beaches to use. Since all headphones then were Dolbys, that came in handy even for DTS media. The PS3 has 3 options, keep native, convert DTS to Dolby, or convert Dolby to DTS. The Xbox One has 3 options, either uncomrpessed 2.0, Convert evertything to Dolby, or convert everything to DTS. (the "keep native" option is also hidden if you check, "let external receiver decode" somewhere else on the menu opitons.)
However on stand-alone movie players, they are not powerful enough to do live transcodings. So most if not all stand-alone media players are in "keep native mode". So if you want to listen to both DTS Movies AND games, you have to buy separate Dobly input headphones, or DTS input headphones. Ironically Turtle Beach has a DTS:X Headphones model, but it only deals in Dobly Inputs. Yes their DTS headsets take Dolby input and convert it to DTS output. I had to send a catalog of all my sotre-bought Blu Rays, listing whether their surround technology was Dolby, or DTS. (I even have one, Apocalypto, which is ONLY LPCM 5.1 via HDMI, since Toslink can only handle LPCM 2.0, good luck converting that, even on a game machine.) They'll consider it if they make a mode for stand-alone movie players primarily. I showed them that a typical collection, by about a 3:2 ratio, favors DTS. Unless you like foreign languages, then yes, everything has Dolby. So our Mexican, Mexican-American (regardless of their paper status, but this has nothing to do with documentation, so no jingoistic Amurica or La Raza statements here.), and Quebecker friends can live with mostly Dolby only.
I tried a dual-standard input surround headphone, like a Sony MDR-DS6500, which uses its proprietary surround-> headphone technology. My Turtle Beach X42s sound great in Dolby, but (for the front room with a stand-alone movie player) were silent on DTS movies. The Sonys were only slightly better, with a passable Dolby, and worse, a flat one dimensional L/R sound on a DTS movie. It says it decodes DTS input. What they didn't say was it outputs DTS into a 2-channel 1-dimensional track, but not as rich as LPCM 2.0.
Can anyone recommend either a) a dual-standard input (tri-standard if you count the Wii U and Switch's LPCM 7.1 via HDMI) headphone that converts both modes into a 2-channel headphone binaural mix, or if not, b) A DTS 5.1+ input-> DTS: X Headphone output, (and as an extra feature, but not a dealbreaker, have either a 3.5mm or L/R out so I can stream in Binaural surround on twitch)?
I see people want directional accuracy in their headphones first. I had a tough time finding movie lovers on LDDB.com, the Laser Disc website, when I asked a straight question like do I need anything to accurately enjoy Dolby 5. 1 movies in my Turtle Beach X41 headset, most people were insulting the idea of getting surround sound out of 2 ear-headphanes. The answer is you need 2 or 3 things, depending on the media, depending on whether you want DTS or Dolby. DTS needs a LD player with Toslink (or Coaxial with Coaxial->Toslink converter) and a DTS input->DTS Headphone output headphone. Dolby needs 3 things, a LD player with both a Toslink output (or Coaxial + a possible Coax->Tos, depending on the next item) and something called an AC3RF Coaxial output built into the LD player. (There are ways to add one if you are a hacker by bypassing the LCPM processor and drilling a coaxial hole routed form the right channel, but I won't go into that), and something called an AC3RF adapter, sometimes called a demodulator or a digitaizer, which takes analog AC3, (remember Laser Disc was originally an analog format and AC3RF was Pioneer's and Dolby's hackery to put a surround track on an analog audio track which has to be converted to standard Dolby 5.1 via Toslink that DVDs and above, and more importantly, stereo equipment, recognize.)This device may have either a Toslink output, a coaxial output (in which case, you need ANOTHER Coaxial->TOslink converter for Turtle Beaches) or both, and finally any brand of Dolby 5.1 or higher-> Dolby Headphone converters.
I have an X41, an X42, and a DSS, an adapter that outputs the resulting 2 track surround sound for stereo streamers, DVD recorders and other media savers. (And yes, playing them back in headphones preserves the surround accurately, but ONLY if you listen via headphones. I recorded an Episode of Star Trek Continues through an x41 which has a 3.5 mm output, and my brother and dad was none the wiser. They didn't say it sounds fake.) If you have a different brand preference,you can either discuss it with us or sillenty make your choice, your choice.
So can anyone recommend a DTS 5.1 or higher input-> DTS Heapdhone output, preferably with a 3.5 mm output? The priority is directionality. I'm not enough of a music fan where playing with treble/bass/midrange can help me.
Finally, we should raid LBBD.com forums to show that there are Headhone lsiteners who would be interested in listening to Laser DIscs on surround headphones. To the naysayers, I say, if you can't get accurate directions in 3D in headphones, then why can I track the apple juice boss on the circumference of an apple and do the magellan and intercept him in Sonic Lost World, and doesn't have Dolby 5.1 via Toslink on the Wii U, so I had to rely on the headphone-0mixed 2-track sound? Same with Legen dof Zelda Breath of the Wild on the Switch, dodging Goblin club swings without seeing them as they are chasing me, and that's a 2-track headphone mix? All the Dolby heapdhones adapter does is convert existing Dolby 5.1 or higher dolby into a 2-channel binaural track.
