While there are several good alternatives to consider, the PHXIN T9S Ultra represents a great value in its class. It is one of the cheaper 10-rider Bluetooth-enabled intercoms available today. It is a lot of bang for your buck considering what you get, including a 2000-meter Bluetooth range, two microphone options for different helmet styles, an IP67 waterproof rating, and a large 800mAh battery offering up to 15 hours of continuous talk or music playback, plus 168 hours of standby time. The unit is compatible with most popular helmet styles, full-face, modular, open-face, and half-shell. See how it stacks up to the competition using our intercom comparison chart.
Communication and connectivity
The T9S Ultra supports up to 10-rider group intercom via Bluetooth. As with all Bluetooth-based intercom systems, the farther apart each rider is from each other (line of sight), the worse the signal will degrade. This product is rated at 2000 meters, approximately 1.24 miles. That distance is competitive with many mesh-intercom products in ideal conditions. Bluetooth technology is improving rapidly and the high-performance Bluetooth chip included in the T9S Ultra performs significantly better than less expensive units claiming longer ranges with more users.
PHXIN states that this product is compatible with LEXIN, MeshCom, and other major brands. There is not always clarity on what "universal" means in practice, but if you are part of a group that frequently partners with other brands of intercoms, cross-brand pairing is an important benefit.
Audio quality
The T9S Ultra uses Mylar coaxial speakers that deliver Hi-Fi stereo sound with 3D audio processing. Like most manufacturers' 3D audio claims, whether true or simply marketing, the coaxial speaker design is a significant upgrade from the typical single-driver speakers found in entry-level models. Intercom voice quality is fine for casual conversation while riding, and music playback benefits noticeably from the dual drivers.
The T9S Ultra features music sharing capabilities between two users. These capabilities work best for riding couples wanting to listen to the same playlists from a single phone.
Noise cancellation
CVC noise cancellation along with the quality of the speakers provides a respectable amount of filterability against wind and engine noise. The specified speed limit for clear communication is approximately 120 km/h (75mph), which is consistent with other CVC-equipped intercoms. The higher you go above that speed or if you encounter unusually heavy winds, the worse the signal becomes. For average highway cruising, the T9S Ultra will handle noise quite effectively.
Build quality and battery life
The T9S Ultra meets the IP67 standard for dustproof and waterproof, capable of withstanding submersion in water for up to thirty minutes at a depth of 1 meter. The operating temperature range is from -20°C to +50°C (-4°F to +122°F), essentially covering all conditions you would encounter during riding.
The 800mAh battery offers continuous talking or music playback for up to fifteen hours, and standby time of up to 168 hours. The included installation kit contains two microphones, one designed specifically for open-face and modular helmets, and another for full-face helmets. No matter what type of helmet you wear, you do not have to purchase additional accessories. The installation process requires no tools and is easy to perform.
Multi-sport compatibility
One of PHXIN's marketing points for the T9S Ultra is that it is intended for use on motorcycles, ATVs, dirt bikes, snowmobiles, and other outdoor helmeted activities. Both the dual microphone option and universal helmet attachment support this flexibility, making the capability more than just a marketing claim for many potential customers. If you ride a motorcycle with one group and a snowmobile with another group that uses different intercoms, the T9S Ultra allows you to communicate with either group without purchasing a second unit.
What reviewers say
At present, due to its recent release, there are relatively few customer reviews for the T9S Ultra, with an early 5-star average based on limited volume. It is too early to draw firm conclusions about long-term reliability from these reviews alone. Based on the generally positive early comments, the T9S Ultra will likely exhibit characteristics typical of its class. Compared to other similarly-priced budget Bluetooth-enabled intercoms, it will likely have slightly reduced actual range versus claimed range in urban or obstructive environments, may experience difficulty canceling excessive noise at faster speeds in extreme winds, and its audio quality will probably not equal that offered by premium brands utilizing Harman Kardon-tuned components. Although PHXIN touts that the device can pair universally with any Bluetooth-enabled headset, connecting to non-PHXIN products may take more effort than they suggest.
Who should buy this intercom
If you are looking for a low-cost 10-rider Bluetooth-enabled intercom with excellent cross-brand compatibility and multi-sport versatility, the PHXIN T9S Ultra is an attractive choice. Its ability to operate in various environmental conditions (such as dusty roads and rainy weather), its inclusion of dual microphone options for different helmet designs, and its ability to connect with multiple brands of headsets will serve most riders well. If you frequently participate in group riding events involving riders who use different brands of intercoms, PHXIN's emphasis on universal compatibility is beneficial.
If you need mesh networking capabilities, look elsewhere at the LEXIN MeshCom, Fodsports FX7, or FreedConn Free+, as mesh networking is currently unavailable on this model. If you prefer superior audio quality or a more refined user interface, Sena or Cardo might be preferable choices at their respective price points. See the full comparison table for more options.
