Two rider-to-rider intercoms for under 100 bucks, with IP65 waterproofing and 652 Amazon reviews backing it up. The Moman H2S is one of the most popular budget motorcycle intercoms on the market and delivers the core features most riders need at a fraction of what Sena and Cardo charge.
This product arrives as a 2-pack, so if you want an intercom for yourself and your riding partner, you have exactly that right out of the box. Bluetooth 5.0 provides connectivity for phones and GPS devices. Moman states a 1000-meter operating distance, but in testing the reliable range with line of sight is more like 500 to 700 meters. The 40mm speakers provide better audio than most low-cost intercom units, and they deliver decent clarity at highway speeds for the price.
Specs and Build Quality
In terms of build quality, the H2S meets expectations for its price class. The IP65 rating means the housing can withstand water, dust, and mud without issue. The housing is plastic but feels sturdy enough for everyday use.
A simple control knob replaces the membrane-style button controls found on low-end intercoms. You can easily adjust volume or skip through songs while wearing gloves, which is a big plus on cold mornings when dexterity is limited.
Moman supplies a clip-on and Velcro mount designed to be compatible with most open face, modular, and full-face helmets. Mounting takes about ten minutes the first time. The 900mAh battery provides the advertised 20 hours of talk time, covering a full day of mixed riding use.
Audio and Microphone Performance
The 40mm speakers deliver decent volume. At highway speeds up to about 70 mph, you can still hear intercom and music clearly. The speaker system handles voice frequencies well, which is what matters most for an intercom. Music playback sounds acceptable for casual listening but lacks the bass response you'd get from premium helmet speakers.
The CVC and DSP noise suppression does a reasonable job filtering wind and engine noise. At speeds under 60 mph, conversations come through clearly with minimal wind interference. Push past 70 mph and you'll notice more wind noise competing with the audio, which is typical for intercoms at this price. The microphone placement matters too. Positioning the boom mic close to your mouth inside the helmet makes a noticeable difference in voice clarity for the person on the other end.
Music quality is passable for calls, GPS directions, and podcasts. If you're a stickler for music fidelity, you may want to upgrade the speakers separately.
What Amazon Reviewers Are Saying
Amazon customers have reviewed the product 652 times and given it an average rating of 4.1 out of 5. Many reviewers praised the value for money and the reliability of the intercom connection. For the price, riders consistently say it exceeds expectations.
Battery life gets a lot of positive feedback. According to buyer reports, the 900mAh battery delivers the manufacturer-stated 20 hours of talk time with typical mixed use. Several reviewers specifically mention using it for full-day tour rides without needing a charge.
There were two main complaints in negative reviews. First, the claimed 1000m range is optimistic. Buyers reported losing connection at around 400 to 500 meters in real conditions with trees or hills between riders. Second, some found the mounting clip less secure than expected on rough terrain, with a few mentioning the unit has vibrated loose on bumpy roads.
Who Is This Intercom For?
The Moman H2S is best suited for riders looking for basic intercom functionality without breaking the bank. This includes couples planning tours together, weekend riders with one passenger, or commuters needing GPS directions and occasional calls. The IP65 rating makes it suitable for all-weather riders. Rain, dust, and cold temperatures aren't a problem. The -20 to 50 C operating range covers most conditions from winter riding to hot summer trips.
This intercom is less suitable for riders needing HD music quality, large group rides, or mesh intercom. The H2S is strictly a 2-way Bluetooth intercom. If you regularly ride with more than one other person, a mesh system would be a better fit. For its intended use case of rider and passenger or two biking buddies, the H2S delivers good value.

Frequently Asked Questions
Does the Moman H2S work with any helmet?
It works with most open face, modular, and full-face helmets. It may not fit thin-shell helmets where there isn't enough space between the shell and your ear. Check that the 40mm speaker fits your helmet's ear pocket depth before committing. For helmets without ear pockets, the included Velvo padding helps create space.
What's the real-world range?
Expect 400 to 700 meters of reliable range in open terrain with direct line of sight. The claimed 1000m is under ideal conditions without obstacles. Trees, hills, buildings, and curves in the road all reduce effective range. In twisty mountain roads, you may notice dropouts at shorter distances.
Can I use it with other intercom brands?
No. The H2S uses proprietary pairing. It connects to another H2S unit for intercom but won't pair with Sena, Cardo, or other brands. If your riding group uses mixed brands, you'll need a universal intercom solution instead. For pairs or small groups running the same equipment, the H2S works great.
How long does the battery last?
About 20 hours of mixed use per charge based on both manufacturer claims and user reports. Standby time is around 300 hours. A full charge takes roughly 2 hours. The 900mAh battery is adequate for day trips and weekend rides with typical use. If you ride all day with constant intercom and music, expect closer to 15 to 18 hours on a single charge.
Is the microphone detachable?
Yes. It comes with a boom mic for full-face helmets and a wired mic for open face or modular helmets. Both are easily detachable and can be swapped depending on your helmet type.
Can I listen to music and use the intercom at the same time?
Yes. Music pauses or lowers automatically when intercom is active. GPS directions also overlay over music during use. This works well for following navigation without missing turns while chatting with a passenger or riding partner.
