3. Setup and Installation
Proper installation is crucial for optimal sound quality and comfort. Follow these steps carefully:
3.1 Speaker Placement
- Prepare the Speakers: Separate the hook and loop velcro stickers. Peel the white paper backing from the rougher (hook) side and firmly stick it onto the back of each XSound 3 speaker.
- Prepare the Helmet: Identify the speaker pockets or suitable flat areas inside your helmet, directly over your ear canals. Peel the white paper backing from the softer (loop) side of the velcro stickers and attach them securely into these speaker holes.
- Position Speakers: Carefully place the XSound 3 speakers onto the velcro pads inside your helmet. Ensure they are positioned directly on top of your ear canal for the best audio clarity and volume.
- Use Foam Spacers: If the speakers do not rest directly against your ears, use the provided foam spacing pads behind the speakers to achieve optimal positioning. Proper alignment is key to experiencing the full sound quality.
- Route Cables: Tuck any excess wiring between the helmet's shell and the padding to keep cables secure and maintain a clean installation.

Figure 3: Speaker Placement Guide. Speakers should be positioned directly over the ear canal. Adjust with foam spacers if needed.

3.2 Connecting to Your Device
The XSound 3 speakers are equipped with a 3.5mm audio pin, making them compatible with most Bluetooth helmet communication systems, smartphones, and MP3 players that feature a 3.5mm earbud or headphone jack.
- Locate the 3.5mm audio output port on your Bluetooth comm system or audio device.
- Plug the 3.5mm audio pin from the XSound 3 speakers firmly into the device's audio port.
- If your device's port is in an awkward position, use the provided 40-inch extension cable for added flexibility.

4. Operating Instructions
The I A S U S XSound 3 speakers are designed to work with your existing audio source. Once connected via the 3.5mm jack, control of audio playback, volume, and calls will depend on your connected device or Bluetooth communication system.
4.1 Audio Playback and Volume
- Ensure your XSound 3 speakers are securely connected to your audio source (e.g., smartphone, MP3 player, or Bluetooth comm system).
- Initiate audio playback (music, navigation, etc.) directly from your connected device.
- Adjust the volume using the controls on your connected device or Bluetooth comm system.
- Important: Volume and sound quality are dependent on the audio source. For optimal performance, pair with a high-quality output device. Adjust volume mindfully to protect your hearing.
4.2 Calls and Voice Assistance
- If connected to a Bluetooth communication system with microphone capabilities, you can typically manage calls and voice assistance through that system's controls.
- Refer to your Bluetooth comm system's manual for specific instructions on answering/ending calls, redialing, or activating voice assistants (Siri, Google Assistant).
5. Maintenance and Care
To ensure the longevity and optimal performance of your XSound 3 speakers, follow these maintenance guidelines:
- Cleaning: Gently wipe the speaker surfaces and cables with a soft, dry cloth. Avoid using harsh chemicals or abrasive materials.
- Cable Care: The Kevlar-reinforced cables are designed for durability, withstanding up to 10 lbs of tension. However, avoid excessive pulling, twisting, or sharp bends to prevent damage.
- Storage: When not in use, store the speakers in a cool, dry place away from direct sunlight and extreme temperatures.
- Adhesive Replacement: The 3M velcro adhesives are durable, but if they lose their stickiness over time, replacement adhesives can be purchased from I A S U S or authorized retailers.
6. Troubleshooting
If you encounter issues with your XSound 3 speakers, try the following solutions:
- Low Volume/Poor Sound Quality:
- Ensure speakers are positioned directly over your ear canals. Use foam spacers to adjust if necessary.
- Check the volume settings on your connected audio device and any intermediate Bluetooth comm system.
- Verify the 3.5mm audio jack is fully inserted into the port.
- Test with a different audio source or device to rule out device-specific issues.
- No Sound:
- Confirm the 3.5mm audio connection is secure.
- Check if your audio device is playing sound and its volume is turned up.
- Ensure the correct audio output is selected on your device.
- Inspect cables for any visible damage.
- Intermittent Sound:
- Check for loose connections at the 3.5mm jack.
- Ensure cables are not pinched or damaged within the helmet padding.
If problems persist, please contact I A S U S customer support for further assistance.
