Features and Build Quality
The Spirit HD allows two motorcyclists to communicate via Bluetooth. The thin 40mm speakers provide good comfort and do not put pressure on your ear when placed in most helmet speaker pockets. The speakers produce HD quality audio that is a distinct improvement over standard intercom speakers. Riders who listen to music at speed will notice the difference right away. The sound is fuller and clearer across the volume range.
One of the main selling points is its complete waterproofing. Cardo rates the Spirit HD as completely waterproof. Rain, snow, mud, and dust will not damage this unit. For riders in rainy climates or those who do not wish to worry about weather, this waterproof capability provides a huge benefit over non-sealed competitors. The housing is sealed well with no exposed ports that could let moisture in.
Built into the Spirit HD is an FM radio with RDS. This means the radio will automatically pick the strongest signal for your area. No manual searching for signals is needed. The radio broadcast goes through the same speakers and can be heard clearly at highway speeds. Riders on long tours find the radio a nice break from music playlists. It works well even in areas with spotty cell reception where streaming drops out.
The ability to receive OTA updates eliminates having to connect the unit to a computer. Updates are handled directly by the Cardo Connect App on your smartphone. Since OTA updates keep the device up to date without requiring much effort, there is no reason to avoid using this feature. New features and bug fixes roll out automatically through the app whenever Cardo releases them.
What Consumers Have Said
The large number of reviews and high rating of nearly 3000 at 4.5 stars gives evidence of consumer satisfaction. Many reviewers state the audio quality from the 40mm speakers is superior to what they had before. Several reviewers also mention being pleased with the waterproof capabilities, especially after encountering heavy rain where they expected their unit to fail. The waterproofing is consistently called out as the main reason they chose this over other options. Riders in the Pacific Northwest and UK mention this specifically as a deciding factor.
Several reviewers have commented positively about the built-in FM radio. Many did not expect to use this feature but now use it regularly. The automatic RDS tuning makes it easy to find and select stations while riding. It becomes a feature riders did not know they needed until they tried it. Commuters especially appreciate having live traffic reports without needing to stream.
Common complaints relate to the cost being perceived as high for a 2-unit system, along with some users wanting longer battery life for multi-day trips. Some reviewers expressed frustration pairing with headsets from different manufacturers. Pairing is straightforward with another Cardo unit but can be tricky with generic Bluetooth headsets. Overall the positives far outweigh the negatives for most buyers.
Why Purchase the Spirit HD
If you ride year-round and experience rain or snow on a regular basis, the waterproof construction alone justifies spending on this over non-sealed intercoms. If you want a full feature set including FM radio, OTA firmware updates, and HD audio without breaking the bank, the Spirit HD fits. It covers all the essentials without pushing you toward the more expensive mesh models.
The single pack lets you start using Bluetooth comms and add a second headset later. For riders who need a 2-person system right away, consider buying both packs at once. The single is a good entry point if you ride solo but want the option to expand later.
Frequently Asked Questions
Are the Cardo Spirit HD headphones truly waterproof?
Yes. They are rated by Cardo as completely waterproof. They handle rain, snow, mud, and dust. Riders report using them in extremely heavy rain with no problems. Do not try to submerge them. Riding in the rain is perfectly fine. The seals around the buttons and charging port keep water out during normal use.
Can I pair multiple riders?
The Spirit HD provides 2-way Bluetooth pairing to a second rider or passenger. For group rides with more than 2 riders, consider the Cardo Packtalk mesh systems. If you ride two-up regularly, the 2-way system is all you need.
Does it have FM radio?
Yes. The Spirit HD has a built-in FM radio with RDS. The radio finds the strongest signal in your area and selects it automatically. No need to tune individual stations. The radio quality is clear at speed and does not cut out like streaming music can in rural areas.
How do I get firmware updates?
Via the Cardo Connect App on your smartphone. All updates are over-the-air with no USB cable or computer needed. The app notifies you when updates are available. The process takes a few minutes and does not interrupt your riding day.
What speakers does it use?
The Spirit HD uses thin 40mm HD speakers designed to fit comfortably in most helmet speaker pockets. Users say they produce superior sound quality compared to typical 36mm speakers from lower cost intercoms. The difference is noticeable at highway speeds where clarity matters most.
Is it compatible with other brands?
The Spirit HD uses Bluetooth and connects to other Bluetooth headsets. Some features like FM radio may not work across brands. It works best paired with another Cardo unit. For mixed-brand setups, basic intercom functions usually work but advanced features may not.
If waterproof reliability and HD audio in a 2-person system are what you need, the Cardo Spirit HD delivers on both fronts. See how it compares on our intercom comparison table.
