Frequently Asked Questions

We recommend you try the helmet on if possible. The helmet has Liner Positioning Control that allows you to adjust the helmet to your head. A proper fit is important for the DXL-5 to actively reduce wind noise.

If you need to buy the helmet online there is a size chart on If you have not ridden with a communication set before please take into consideration that some of our test riders in that situation chose to go up one size from their earlier helmets.

Yes, the helmet is not included in the DXL-5.  You need a X-Lite X-1005 from Nolan. Both the Elegance and Ultra Carbon editions are ok. The Ultra Carbon is lighter, the Elegance is for some riders more quiet. The DXL-5 will not fit other helmets. We need to know your helmet size to send you the right size cheekpads – that you easily replace in the helmet.

Yes. The DXL-5 is an ANC-enhanced version of the N-Com B902 X with all its features. See information from N-Com on

Yes. We are working on other helmets and systems, we will update our website with news as they come. But do not expect this to happen very soon as certifications and lead time components is a major factor.  

We see very good effect up to 100 km/h – more depending on bike, conditions and the rider. We process noise and feed back to your in-helmet headphones cancelling noise-waves. Noise from wind increases more than the percentage increase in speed and “louder” cancelling noise-waves are needed from the amplifier with the increase.

We have patents that covers both mechanical/physical aspects and how we process noise. Without going into details, we reduce in this product mainly “Brown Noise”. Our algorithm evaluates constantly and adapts the noise cancelling.

No. The DXL-5 has all the functionality the B902 X has, but you can not get the DXL-5 as an “add-on” to your B902 X as we do changes to the system in our production process.

The DXL-5 is an around the ear headset, so there is room in the concha (cavity in the ear outside the ear canal). But if there is sufficient room depends on the hearing aid, I guess.  

What we know is that DXL-5 is currently successfully tested by users wearing glasses and with sufficient room for the temple and temple tip. But a hearing aid might require more space behind the ear for the battery module, and the depth of the hearing aid outside the ear canal cannot be too big. So, we unfortunately do not have a clear answer. Also, in general we cannot recommend use of hearing aid or other “hard items” in combination with our system, as this will very likely not be according to how this product is being homologated (crash test with system inside).  

Regarding fit; a good first test could be to approach a retailer and test a X-lite X-1005 helmet while wearing the hearing aid.  

But as stated, this is not something we can recommend yet.

The DXL-5 is not a medical device. We remove wind noise that we do know that many tinnitus-suffers find especially bothering. We have seen interest from many with these challenges.

Yes. The DXL-5 analyse continuously and remove wind noise. All other normal sound – such as traffic, sirens, talking, your bike – is there. Most test riders think we amplify other sounds as you hear them more clearly without the pollution of the wind noise. But of course, if you are on the phone or listening to music you may miss the sirens anyway…

Cheap foam earplugs – or more expensive medical grade silicone plugs with or without filters – will reduce all sounds and you may lose important noise from the environment around you. Many riders find it bothersome to ride with plugs in their ears. It is also a bother to put them in before the helmet and making sure they have a good fit. With the DXL-5 you put on your helmet and ride. On your first ride, or when you need, the system performs a “fit test” checking that the headset cushion in the helmet closes properly around the ears. The DXL-5 is Active, meaning that we continuously adapt to the environment around you.

The ANC term is used about many systems. The Noise Control part is common in many products. A noise-cancellation speaker emits a sound wave with the same amplitude but with inverted phase (also known as antiphase) relative to the original sound. The Active part is sound reduction using a power source – and for us in DAAL it is also the ability to continuously analyse and intelligently act on the noise around you, and not only based on a pre-programmed set of parameters.

Always check local regulations in the country you ride in, but Yes. Two aspects. Communication systems generally (if fitted in/to the helmet) need to be homologated. Meaning that crash testing has been done and the helmet with communication system installed is certified by the relevant authorities. Nolan (maker of the X-Lite X-1005) have that in place for our system.

Secondly – you as a rider need to pay attention in traffic and hear what is going on around you. DXL-5 reducing wind noise is not an issue – our test riders report increased awareness of environmental sounds. But earplugs (passive noise control) or loud music that means you do not hear sirens etc may be.

For now we are dependent on that you know somebody that have bought the DXL-5 and that their helmet fits your head. As with most communication systems. We plan to change to a dealer-based distribution in the future so you at least can see the box before you buy, but this may take some time and change pricing.

The first DXL-5’s will be shipped to customers fall 2022. We will publish videos of the system and tests on this website at that time.
