7.1 Surround Sound Test
Tap a speaker to hear where it should be. On headphones the sound is placed around your head with the same 3D audio (HRTF) technique games use; on a real 5.1 or 7.1 system, each channel plays on its own speaker.
Headphones: tap the speakers around the head. Front and back are harder to tell apart than left and right; that is normal.

Testing virtual 7.1 on headphones
Headphones have two drivers, so "7.1 on headphones" is always virtual: software filters each sound the way your head and outer ears would if it arrived from a given direction. This page does the same in your browser with a head-related transfer function (HRTF), so you can hear what positional audio is supposed to sound like before you blame a game or a headset.
What to expect:
- Left, right and the sides should be obvious. If SL and SR are not clearly on your left and right, run the left right sound test first.
- Front versus back is the hard part. A generic HRTF is not fitted to your ears, so many people hear the back speakers as "inside the head" or even in front. That is a limit of all virtual surround, not a fault.
- The subwoofer (LFE) has no direction. You should hear centred thumps.
Turning on spatial sound for games
- Windows 11: Settings → System → Sound → your headphones → Spatial audio → Windows Sonic for Headphones (free) or Dolby Atmos for Headphones / DTS Headphone:X (apps with a paid licence).
- Gaming headsets with "7.1": the virtual surround is switched on in the maker's app or with a button on the headset. Turn it on, then tap the speakers on this page again: the positions should become more distinct.
- Mac, iPhone and iPad: Spatial Audio for AirPods and Beats works in apps that support it, such as Apple Music and many video apps. A web page receives normal stereo, so this test runs the browser's own HRTF instead.
- PlayStation 5 and Xbox: enable 3D Audio (PS5) or Windows Sonic / Dolby Atmos (Xbox) in the console's audio settings.
Do not stack two virtualisers. If the game has its own "headphone" or "binaural" mode and you also switch on Windows Sonic or the headset's 7.1, directions get blurrier, not sharper. Pick one.
Testing a real 5.1 or 7.1 speaker system
Connect the computer to the receiver or the multichannel speakers, set the output to 5.1 or 7.1 (Windows: Sound settings → your output device → speaker setup; macOS: Audio MIDI Setup → Configure Speakers), then reload this page in Chrome or Edge and press Use my speaker channels. A button appears for each channel; each should play on its own speaker only. If the browser still reports two channels, the system is set to stereo, or the connection (for example many HDMI TVs) only passes stereo from a computer.
Frequently asked questions
Is 7.1 surround on headphones real?
It is real processing, but virtual positions: two drivers plus filtering that mimics sound arriving from different directions. Good implementations make footsteps and gunfire easier to place; none matches true speakers for front-back accuracy.
Why does the back speaker sound like it is in front?
Front and back sounds reach both ears at almost the same time, so the brain relies on subtle colouring by your outer ear. A generic 3D filter does not match your ears exactly, which causes front-back confusion. It is the most common limitation of virtual surround.
Do I need a surround headset to use this test?
No. Any stereo headphones work for the virtual test, because the 3D positioning is done in the browser. A "7.1" headset only adds its own extra processing.
What does LFE mean?
Low-Frequency Effects, the ".1" in 5.1 and 7.1: a separate channel for the subwoofer that carries explosions and deep effects.
