SINCE 2001 · DESIGNED IN HOUSE · ENGINEERED FOR HELMET AUDIO
THE TECHNOLOGY
Engineered for Audio Inside Your Helmet
Helmet speakers operate in a different environment from conventional headphones. Limited space, ear positioning, helmet padding, and surrounding noise all influence the listening experience.
The XSound 2.1R is designed specifically for this environment, combining a compact speaker assembly with a stainless steel acoustic chassis and reinforced wiring.
1. Stainless steel acoustic chassis
The stainless steel housing forms the structural foundation of the XSound 2.1R speaker assembly. Its design supports the acoustic performance of the driver while providing a durable, compact construction for installation inside a helmet.
2. 40mm full-range driver
Output tuned for the enclosed acoustics of a helmet. Solid, punchy bass with clear, detailed highs.
3. 3.5mm connector
The XSound 2.1R uses a standard 3.5 mm audio connector, allowing connection to compatible audio devices and systems with a corresponding speaker output. Some devices require an adapter. Compatibility and maximum volume depend on the connected source.
4. Kevlar reinforced cable
The reinforced cables are designed to withstand the demands of regular helmet use. The asymmetric cable lengths help route the wiring behind the head and beneath the helmet lining for a tidy installation. Custom length left 40cm / right 20cm, reinforced so it survives thousands of helmet on-offs.
TUNED FOR THE RIDE
Helmet Speakers for Music, Communication, and Navigation
Your helmet is not a quiet listening room. Wind, engine noise, helmet fit, and speaker placement all affect what you hear.
The IASUS XSound 2.1R is designed to deliver music and spoken audio through a compact wired speaker system that fits inside compatible helmets.
Music – Enjoy more of the soundtrack.
Listen to your favourite music with bass presence and high-frequency detail in a compact helmet audio setup.
Communication – Keep your audio setup connected.
Connect the XSound 2.1R to compatible communication systems that support external wired speakers. For riders using IASUS communication equipment, it can form part of a larger helmet audio setup.
Navigation – Hear the next turn.
Listen to GPS instructions and navigation prompts through a compatible connected device, without needing conventional headphones inside your helmet.
Important: Actual audio performance depends on the source device, output power, speaker placement, helmet fit, and ambient noise. The speakers should be positioned correctly and used at safe listening levels.

THE BRAND
We only do one thing: audio inside the helmet.
IASUS Concepts designs and builds helmet headsets, and has since 2001. No phones, no gadgets, no side projects. Just headsets that hold up when the ride gets loud, tested on MotoGP bikes and worn by riders around the world.
WHY STOCK SPEAKERS FALL SHORT
Most helmet speakers are too quiet. You crank the volume and get distortion.
Stock speakers thin out the moment wind and engine noise rise. You turn it up, and instead of clarity you get crackle. The XSound 2.1R starts with a stainless steel chassis and 40 mW of power, so the volume is real, and it stays clean where stock speakers fall apart.
HIGH BASE, HIGH TREBLE OUTPUT
Wide bass, clear highs, power to spare.
The XSound 2.1R delivers high fidelity sound at all volumes, engineered for music, calls and navigation in the loudest environments.
Music

FREQUENTLY ASKED QUESTIONS
Everything riders ask.
Do the XSound 2.1R 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 2.1R 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 2.1R fit in tight helmets?
Most helmets accommodate the XSound 2.1R’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 2.1R. In this case, reach out to us for more assistance.
Are the XSound 2.1R speakers compatible with all motorcycle headsets?
The XSound 2.1R 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 2.1R speakers safe to use at maximum volume?
The XSound 2.1R 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 2.1R speakers come with foam spacing pads?
Foam spacing pads are included with all XSound helmet spekaer models to help achieve proper ear contact.
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 2.1R 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 2.1R speakers optimized for the REKON system?
Yes. The XSound 2.1R is acoustically tuned to pair perfectly with the IASUS REKON LTE communication system, delivering enhanced clarity for music, navigation, and voice communication.
