XSound 4 Helmet Speaker

Do the XSound 4 speakers need to touch my ears?

Yes. For optimal performance, the speakers should sit flush against your ears inside the helmet.

Direct contact ensures:

• Maximum volume efficiency
• Strong bass response
• Minimal audio loss
• Reduced distortion

If there is a gap between the speaker and your ear, you may be tempted to increase volume excessively, which can damage the speakers over time.

Where should I position the speakers inside my helmet?

For best results, mount the speakers:

• Directly aligned with your ear canal

This positioning improves comfort and acoustic seal while preventing ear folding.

How can I test the optimal speaker position before installation?

Before mounting:

• Connect the speakers directly to your smartphone or music player using the 3.5 mm cable.
• Hold the speakers directly against your ears.
• Play music at your typical riding volume.

This allows you to benchmark the sound quality and determine the ideal positioning before installing them in your helmet.

Why does proper alignment matter so much?

Helmet acoustics are enclosed and highly sensitive to positioning. If the speaker shifts or your ear folds when putting on the helmet:

• Volume may decrease
• Bass response may weaken
• Sound clarity may suffer

The XSound 4 is engineered to perform at its best when properly aligned.

What is the Ear Unfolding Tab and how do I use it?

The Ear Unfolding Tab is included to help riders reposition their ears after putting on a tight-fitting helmet.

If your ear folds during helmet entry:

• Open your visor or access from the bottom opening
• Use the thin tab to gently reposition your ear
• Ensure the speaker sits flush against the ear surface

This small adjustment can dramatically improve sound quality and comfort.

Will the XSound 4 fit in tight helmets?

Most helmets accommodate the XSound 4’s. Before purchasing, consider whether your helmet has sufficient ear pocket space for added components.

Why do I hear crackling or distortion at higher volumes?

If distortion occurs:

• Connect the speakers directly to a smartphone or music player.
• Play audio at the same volume level.

If distortion disappears, your motorcycle headset or Bluetooth receiver is likely the limitation. Some stock communication systems do not support full output, especially when paired with high performance speakers like the XSound 4. In this case, reach out to us for more assistance.

Are the XSound 4 speakers compatible with all motorcycle headsets?

The XSound 4 is designed to replace stock helmet speakers and works with most systems that use a 3.5 mm output.

However, due to the wide variety of motorcycle headsets and Bluetooth receivers on the market, IASUS cannot guarantee compatibility with every model.

Are the XSound 4 speakers safe to use at maximum volume?

The XSound 4 is engineered to handle maximum output from smartphones and music players without distortion.

However, listening at excessive volume levels may cause temporary or permanent hearing damage. We strongly recommend using safe listening levels, especially during long rides.

Why might volume seem reduced after installing the speakers?

Reduced volume is typically caused by:

• A gap between the speaker and your ear
• Ear folding inside tight helmets
• Improper speaker alignment

Ensuring flush positioning restores full audio performance.

Do the XSound 4 speakers come with foam spacing pads?

Foam spacing pads are included with all XSound helmet spekaer models to help achieve proper ear contact.

The XSound 4 uses upgraded Acoustic Flex (AF) Technology covers to naturally mold to the ear and maintain optimal positioning without traditional foam spacers.

What is the lifespan of the cables?

Due to global RoHS environmental compliance requirements, modern cable materials are biodegradable over time.

This means that, like most wired headsets (including major brands), the cable material may naturally break down after extended years of use. Proper storage and avoiding extreme environmental exposure can help extend lifespan.

How can I maximize the lifespan of my XSound 4 speakers?

• Avoid excessive volume levels
• Ensure proper ear alignment (no volume compensation needed)
• Store in a dry environment
• Avoid excessive pulling or tension on cables

The Kevlar-reinforced wiring is designed for durability, but responsible use ensures long-term performance.

Are the XSound 4 speakers optimized for the REKON system?

Yes. The XSound 4 is acoustically tuned to pair perfectly with the IASUS REKON LTE communication system, delivering enhanced clarity for music, navigation, and voice communication.
