The number of riders a particular headset is intended for varies widely. While some riders would benefit greatly from a mesh network connecting 10 riders, others could simply settle for a four-rider Bluetooth intercom. Most couples and small groups don't often encounter situations where a Bluetooth-based group is not sufficient. The YTerrix Q4 was designed for this type of user with a 1500 meter range and dual-phone pairing thanks to its dual-chip technology. It sits beneath the larger mesh networks, such as the XGP X10, on our intercom comparison table.
Communication and connectivity
Four riders can communicate with each other at the same time in the primary intercom mode of the Q4, and YTerrix claims a 1500 meter rider-to-rider range in open terrain. It is possible for the Q4 to connect six riders through daisy-chain pairing, but riders beyond the fourth will likely notice an increased rate of disconnection. The full 1500 meter range is typically achievable only between the two nearest riders. Under normal operating conditions, the maximum distance between the closest riders is about 500 to 700 meters before obstructions in the surrounding area reduce the range.
Bluetooth 5.1 and a dual-Qualcomm chip design power the Q4. Dual-phone pairing works through two chips that can connect two phones at once. The advantages include being able to use one phone for business calls and another for personal music, or letting your passenger share music from their own phone without disconnecting the GPS. Music can also be shared between two Q4 units.
Audio quality
The Q4 uses 40mm HD speakers that were optimized for voice and music clarity. Owners report that they enjoy clean-sounding music at city and highway speeds, and that there is enough volume to compete with sustained wind on full-face helmets. Voice audio quality is equally strong inside the four-rider group, and audio multitasking keeps music at a lower volume during voice communications and GPS navigation prompts.
The Q4 has an integrated FM radio receiver, which is an advantage when cellular service is unavailable or when you want to preserve your phone battery for long rides.
Noise cancellation
YTerrix uses DSP noise cancellation combined with a foam windshield over the boom microphone. Together these elements help eliminate background noise in urban and mid-highway riding environments. Owners have stated that conversation remains clear up to approximately 65mph on properly sealed full-face helmets. At speeds greater than 65mph, wind noise begins to bleed into the microphone signal. Wind pickup is more prominent at sustained highway speeds for half-helmets and three-quarter shells.
Build quality and installation
The YTerrix Q4 mounts through a sliding aluminum bracket attached to an adhesive-backed plate. The enclosure has an IP65 rating indicating protection against dust and water sprays from any angle. So far, none of the early users have experienced failure due to rain exposure. The controls are laid out clearly and compactly, with a single rotary dial for volume and three buttons for intercom, phone, and mode switching. The buttons are large enough to be used with gloved hands.
Typical installation time for the Q4 on the first helmet is around fifteen minutes. The speakers mount onto standard helmet ear pockets via Velcro-backed pads. A boom microphone is supplied for use with modular and open-face helmets, and a wired microphone with a soft windscreen is provided for tight full-face helmets. Transferring speaker pads from one helmet to another is simple because each pad adheres securely to the ear pocket and comes off easily.
Battery life and charging
Based on information from YTerrix, the Q4 has 15 hours of continuous talk time and 200 hours of standby. Charging through USB-C takes approximately 2.5 hours. Assuming typical weekend day rides of six to eight hours with music and intercom active throughout, the battery will retain approximately 30 to 50 percent charge remaining at the end of the ride.
What reviewers say
The Q4 is a relatively new model with a modestly sized reviewer base of approximately 33 ratings and an average of 4.7 stars. Initial purchasers consistently praise the Q4 based on three aspects. First, the dual-phone pairing works as described and is advantageous for riders managing work calls while listening to personal music, or riders whose passengers wish to play music from their own phone without disrupting GPS. Second, the IP65 rated enclosure has resisted water ingress during prolonged rain riding. Third, owners agree that the audio quality and general construction exceed what is expected at an entry-level price point.
Because the Q4 has been available for only a short period, reliable long-term test results are not yet available. Riders seeking a longer reliability record may prefer an existing Bluetooth intercom like the Fodsports M1-S Plus, which has thousands of reviews detailing its long-term performance. For early adopters who want newer features, current owner feedback on the Q4 is overwhelmingly positive.
Who should buy this
Couples traveling two-up or separately on individual motorcycles, groups of friends consisting of two to four riders wanting a simple Bluetooth intercom solution, and commuters needing phone calls, music, and FM radio in one unit are all potential candidates for the YTerrix Q4. The dual-phone pairing capability makes this a unique feature compared to similarly priced Bluetooth intercoms, particularly for riders who must stay reachable on multiple phones.
Mesh self-healing is not supported for larger groups, since the Q4 relies on traditional Bluetooth daisy-chaining. Existing users of Cardo or Sena systems should also continue utilizing those products for brand compatibility, since the Q4 can only connect to other brands through universal Bluetooth pairing. Riders who plan to participate in track days requiring certified radios should seek alternative options.
FAQ
Will the Q4 actually support six riders?
Four riders can be paired together in the primary intercom mode of the Q4. When daisy-chained, up to six riders can be connected, although additional riders will increase the frequency of disconnections among those farther out in the chain. We recommend maintaining a maximum of four riders per group for stable performance.
Does dual-phone pairing really work?
Yes. The dual-Qualcomm chip design allows two phones to be connected to the Q4 at the same time. Riders can switch between music sources and answer or receive calls on either phone without manually disconnecting.
Is the claimed 1500 meter range realistic?
Owners have reported ranges exceeding 1000 meters in open terrain with clear line of sight between riders. Typical testing in mixed terrain shows 500 to 700 meters between adjacent riders. Daisy-chaining extends the group reach, but coverage at the edges drops off with more distant riders.
What is the waterproof rating?
The Q4 carries an IP65 rating, which protects against dust ingress and water splashes from any direction. None of the early users have reported water leaking into the unit after rain exposure. Keep the USB-C port cover closed when not charging.
Can the Q4 pair with Cardo or Sena units?
Yes, but only through universal Bluetooth pairing, which supports a two-rider voice call. The 4-rider group intercom works only between Q4 units and compatible YTerrix models.
