I bought a Razer Tiamat 7.1 headset. I was a bit silly though and thought the USB that connect the headset to the computer was not just to power the headset. I'm using a laptop and it obviously doesn't have a 7.1 sound card. It does come with female 3.5mm jacks to micro USB, but those are meant for connecting other speakers through the control unit of the headphones. Maybe there is a way to hack it so it uses it to connect the headphones to the laptop's USB instead, but I doubt so...

So are their any decent solutions for going from 7.1 3.5mm jacks to USB or HDMI? Also I don't want to spend more than $50 on a solution for this. Otherwise I guess I'll be destined to use it in 2.1 mode until I upgrade to a desktop.

  • Would an external USB soundcard suffice? These are readily available from a variety of companies for a wide array of budgets. Commented Jan 18, 2016 at 11:12
  • yep that would prob be the best solution, ive looked around online at some local shops and a 7.1 external sound card seems quite pricey unfortunately, maybe they just dont stock the cheap ones

I'd say it's not worth spending more money to get more performance out of this or any other 7.1 headset. Just use it in stereo mode if you have no 7.1 source.

Operating systems and applications like games or media players are responsible for handling sound: selecting the appropriate output path and channel profiles, applying dynamic range compression where necessary and so forth. This is particularly true for games where the soundscape is rendered by the game engine and it doesn't get more accurate with 2 speakers or headphones than the game engine knowing that it should render a stereo signal. A multichannel downmix by an unknown element in the chain doesn't improve the result it's just a dishonest, technophobe marketing myth and number game that is still around.

enter image description here

If you need a visual example, download Audacity or any other audio editor, load a multitrack audio track from a movie or audio recording and mix it down to stereo. Many people pretend to care much about clean audio. Does the downmix with information from all channels look cleaner or more detailed to you? No, it doesn't! Good games are able to mix all the information into a high quality stereo signal. With the rise of VR binaural audio will get more important and virtual 7.1 mixes will hamper your immersion. Please let game engines do their work without interference, the game designers who put them together should know better how to treat audio that they or their customers create.

I could suggest to you to get a cheap 7.1 USB soundcard from China, but that's worse than your built-in sound solution. A multichannel audio production interface can actually deliver good quality but is at least three times out of your budget, not very portable and the Windows drivers don't support running the channels as a 7.1 configuration for gaming while the hardware is capable of doing so. I'd rather recommend an O2+ODAC or a similar product and reference headphones if you're already willing to spend +150 USD.

Here is a review from a Razer fan who isn't very impressed with this headset either. I found this video while looking for a picture of the connectors.

  • the review seems a bit biased heh, the comment section seems to disagree with the reviewer, but could just be razer fanboys, hopefully i havnt made a mistake buying this headset
