Touring couples and riding partners looking to save money by buying two intercoms in a single package generally search for a 2-pack product. The ASMAX S1 is an 8-rider mesh intercom sold as a 2-pack that also inherits ASMAX's 5G CloudTalk functionality for long-range group chat. It sits in the mid-to-premium mesh segment of our intercom comparison table, alongside the single-unit ASMAX F1s, which uses essentially the same architecture.
Communication and connectivity
The S1 is built on mesh technology developed by ASMAX and supports up to 8 riders in a single mesh network. The company states the mesh network provides a five-mile range between riders in fully open terrain. In most real-world riding, expect roughly 700 to 1100 meters between the two closest riders once trees, hills, and traffic enter the picture. The daisy-chain effect of mesh allows the rest of the group to extend much further down the trail in relation to the first rider.
Two operational modes are available. Free Mode allows users to communicate via open intercom within Bluetooth range, and Group Mode establishes a private communication channel for a user-defined group while rejecting outside units.
The 5G dual-network system is the S1's standout capability. If a rider leaves mesh range, the unit can switch to 5G CloudTalk through the paired smartphone, which allows the group to continue their conversation over cellular networks rather than losing that rider. This hybrid approach is particularly advantageous during long adventure tours where riders split off to find trails and rejoin the group later. Cross-brand Bluetooth pairing is also supported for two-rider voice calls with Cardo or Sena units.
Audio quality
The S1 uses 40mm speakers optimized for both voice communication and music listening. Owners consistently describe the audio quality as clean and loud enough to remain enjoyable at highway speeds in full-face helmets. Music can be shared between paired S1 units, and FM radio is included as an additional music source for riders in rural areas where streaming is unreliable. Audio multitasking allows riders to keep music in the background while receiving GPS directions or an intercom call.
The microphone on the S1 is a boom-style unit with a foam windshield. Transmitted voice quality stays clear across the entire 8-rider mesh group. Multiple owners mention that even with several riders in close proximity on narrow roads, each voice remained easy to understand.
Noise cancellation
ASMAX applies noise cancellation to the outgoing voice signal to suppress wind noise and road rumble. The S1 holds clean voice quality up to 70mph on properly fitted full-face helmets. Open-face and three-quarter shell helmets allow more wind at sustained cruising speeds, which is consistent with every mesh intercom in this class. Noise tuning improvements are released periodically as part of FOTA updates, providing a long-term advantage.
Build quality and installation
The mount is a thin slide-in clamp with an adhesive backing plate. The body is rated waterproof for normal riding conditions, and owner feedback confirms no failures after extended rain exposure. Smart Voice Control is integrated into the unit, which lets users perform common tasks without taking their hands off the handlebars. Intercom and phone functions are handled through two physical buttons, and volume is adjusted using a rotary dial.
Approximately 15 minutes is required to install the first helmet, and subsequent installations take significantly less time. Velcro-backed speaker pads drop directly into standard helmet ear pocket positions. Modular and open-face helmets use the included boom mic, and a wired mic with fabric windshield accommodates tight full-face helmets. The ASMAX app manages firmware updates, group creation, and EQ settings.
Battery life and charging
ASMAX rates the S1 at 15 hours of continuous talk time and more than 240 hours of standby. The unit charges over USB-C in just over 2.5 hours. Using both mesh connectivity and intermittent CloudTalk over a full day, many riders report ending the ride with 30 to 50 percent battery remaining, which matches the manufacturer spec.
What reviewers say
Overall, the S1 averages 4.4 across more than 1,000 reviews, which is a reasonable baseline for a 2-pack at this price. Owners consistently identify three positives. First, the 2-pack form factor makes purchasing easier for touring couples because both units arrive pre-paired. Second, the 5G handover function works reliably in areas with good cellular coverage and keeps the group connected across longer distances. Third, many owners find that the audio quality represents an improvement over single-chip designs at a similar price point.
Critical feedback focuses on two areas. First, in regions with poor cellular coverage, the 5G handover reduces in usefulness and the unit falls back to mesh-only operation. Second, FOTA updates occasionally introduce minor software issues that cause frustration among early adopters until a follow-up firmware resolves them. This is typical of connected-device platforms but still worth noting.
Who should buy this
Based on its specifications and performance characteristics, the ASMAX S1 is a strong choice for touring couples and rider pairs who want a matched set of two mesh-capable units with cloud-based support for long-distance group communication. Small motorcycle clubs of four to eight members that want mesh networking plus 5G handoffs will also benefit, particularly if riders often split off during adventure tours and rejoin later. FM radio, FOTA updates, and Smart Voice Control round out the package for motorcyclists who want a connected intercom without Cardo Packtalk pricing.
This is not the recommended choice for riders who mostly operate outside cellular coverage, because CloudTalk's effectiveness diminishes outside of coverage. Riders currently committed to Cardo or Sena devices are likely better served by staying within those ecosystems, because the mesh networking feature works only between ASMAX branded products. Track-day riders who require certified radios should also review alternative options before choosing a consumer mesh intercom.
FAQ
How is the S1 different from the ASMAX F1s?
Both use ASMAX mesh networking technology. The main differences: the S1 is sold as a 2-pack while the F1s is a single unit, the S1 caps at 8 riders while the F1s supports 10, and the S1 is marketed and purchased as a matched pair.
Is there a cost to use CloudTalk?
CloudTalk uses cellular service through a paired phone for routing group chat beyond mesh range. There is no subscription charge from ASMAX. Carrier data charges apply based on your cellular plan.
How realistic is the claimed five-mile range?
The five-mile figure is achievable only in open terrain with unobstructed line of sight. In typical mixed-terrain riding, riders see roughly 700 to 1100 meters between adjacent riders. Each rider acts as a mesh relay, which extends total group reach beyond the immediately surrounding riders.
Does the S1 pair with Cardo or Sena units?
Yes, through universal Bluetooth pairing, which supports a two-rider voice call. Only ASMAX S1 units and compatible ASMAX models participate in the 8-rider mesh group.
How long does the battery last in daily riding?
With a rated 15 hours of talk time and 240 hours of standby, the S1 covers a full riding day with intercom and music active and typically finishes with 30 to 50 percent battery remaining. A bike-mounted USB-C outlet is useful for multi-day tours to keep a reserve ready.
