The XSound 3 is a precision-crafted audio product. Therefore, they need to be installed precisely in contact and centered on your ears for accurate sound projection. Any gaps nd poor centering will result in poor audio quality and volume for wind and other ambient noises.
The XSound 3 was designed and tested for use with IASUS Stealth, Rekon, and Mobile Amplifiers, as well as smartphones, and digital media players equipped with a 3.5mm jack.  s such, the left speaker cable is longer than the right. Each XSound 3 speaker is designated left “L” and right “R” on the lightweight CNC aluminum housing. ASUS does not directly support using the XSound 3 with a non-IASUS Bluetooth motorcycle headset. Please use at your own risk.
We strongly recommend testing your speakers outside of your helmet first before installing them by doing the following:

  • Connect the XSound 3 directly to your smartphone’s 3.5mm jack.
  • Hold the speakers in contact and centered on your ears while testing the audio. Any gaps will compromise the sound.
  • Adjust the position of the speakers on your ears until the audio sounds the best. Remember their positions.


  1. Wipe away any dust or debris on the surface where the XSound 3 will be installed onto.
  2. Peel apart the Velcro adhesives (B1/B2) to reveal the loop and hook halves. They arrive in the box stuck together.
  3. Peel away the backing paper on the loop piece (B1). Attach the loop piece into your helmet.

  5. Place the XSound 3 (A) onto the velcro piece inside the helmet.
  6. Repeat steps 1-5 for the other side.
  7. Tuck the wires behind the helmet padding for a tidy installation.

  8. Connect the XSound 3 to your audio source device. Use the 3.5mm Extension Cable (F) if necessary.


  • Ensure the XSound 3 helmet speakers are once again fully contacting your ears and centered on them after putting your helmet on. If they are not centered, reposition the XSound 3 inside your helmet.
  • If they do not make good contact, place a Foam Pad Spacer (C) in between the helmet and the XSound 3.
  • For an increase in comfort, try placing the Comfort Fit Covers (E) over the Foam Covers (D).

You may sometimes find that after putting on your helmet, your ears may be folded against the speakers. This will prevent the XSound 3 from making full contact on them, resulting in poor audio quality and lower volume. To remedy this, IASUS has included the Ear Tab.
To use, insert the tab on either side of your helmet’s eye-port. Slide it between the XSound 3 and the folded ear until it is unfolded.
For easy transport, the Ear Tab can be conveniently secured to your keys with the included key chain fob.
