The SHOKZ OpenRun, model S803, represents a specialized category of audio wearables: open-ear bone conduction Bluetooth headphones. Designed primarily for athletes like runners and cyclists, these headphones forgo traditional earbuds entirely. Instead, they transmit audio via vibrations through the cheekbone to the inner ear, leaving the ear canal unobstructed. This design prioritizes situational awareness and comfort during physical activity over absolute audio isolation. The bottom line: the Shokz S803 is a purpose-built tool for active users who value safety and a secure fit during workouts above deep bass or complete privacy.
Bundled with a sports headband, these headphones feature an IP67 water resistance rating and are marketed for their lightweight, wraparound frame. They promise up to eight hours of battery life with a quick-charge function. This review analyzes the specifications, design philosophy, and user feedback to determine who will benefit most from this unique audio technology and where traditional headphones might still be the better choice.

Design and Build
The Shokz S803 employs a distinctive wraparound titanium alloy frame that rests behind the head, with transducers positioned just in front of the ears on the cheekbones. This open-ear design is the core of its identity, eliminating any in-ear or on-ear pressure. The construction uses a combination of nickel-titanium alloy, plastic, and silicone, resulting in a claimed weight of just 26 grams. This featherweight build is a critical feature for reducing fatigue during long runs or cycles.
The bundle includes a Shokz sports headband, which is designed to work in tandem with the headphones. The headband features a non-slip design with silicone inserts to prevent movement during vigorous activity. An IP67 waterproof rating means the headphones are built to withstand intense sweating and rain, though the manufacturer specifies they are not suitable for swimming or submersion. The physical design is clearly oriented toward securing the device comfortably on the head without interfering with helmets, glasses, or hats.
Performance and Features
Audio Performance and Bone Conduction Technology
The Shokz S803 utilizes what the company calls its 8th generation bone conduction technology. Sound is generated via vibrations transmitted through the cheekbone directly to the inner ear, bypassing the eardrum. The audio driver is a bone conduction type with a listed frequency range of 20Hz to 20,000Hz. According to specifications and user feedback, this technology delivers clear audio for music, podcasts, and particularly for voice calls, but it naturally lacks the deep bass response and audio isolation of traditional in-ear headphones. The open-ear nature means some sound leakage can occur in very quiet environments.
Connectivity and Controls
Connectivity is handled by Bluetooth 5.1 with a stated range of up to 10 meters. The headphones are universally compatible with Android, iOS, Windows, and other Bluetooth-enabled devices. Controls are physical buttons integrated into the frame for functions like volume control, call management, and playback. The device supports multipoint pairing, allowing it to connect to two source devices simultaneously, which is useful for switching between a phone and a computer.
Battery and Charging
The Shokz S803 is rated for up to eight hours of continuous playback on a full charge. A key feature is the fast-charge capability: a 10-minute charge via the included magnetic induction cable can provide up to 1.5 hours of battery life. This is a practical benefit for users who might forget to charge before a workout. The magnetic charging system also contributes to the high water resistance by eliminating open charging ports.
Setup, Support and Ownership
Setup is straightforward, involving a standard Bluetooth pairing process with a smartphone or computer. The package includes the headphones, a magnetic charging cable, a protective carrying case, and the sports headband. The manufacturer, Shokz, offers a two-year warranty on the product. For those interested in related audio gear, our site features guides on other sound equipment like the best soundbars.
Ownership considerations include the proprietary magnetic charging cable, which must be kept track of for charging. The IP67 rating ensures durability against sweat and rain, but users must avoid submersion. The open-ear design means there are no ear tips to replace or clean, simplifying long-term maintenance compared to traditional earbuds.
What Owners Say
Owner reviews are overwhelmingly positive, with a high percentage of top ratings. The most praised aspects are the comfort for all-day wear, the security of the fit during sports, and the ability to maintain environmental awareness. Many users with sensitivity to in-ear headphones or tinnitus report significant comfort benefits. The sound quality is generally described as good for its intended purpose—listening during activity—with clear calls and adequate music playback, though it is consistently noted that these are not for critical listening or audiophiles.
Some critical feedback mentions the restricted maximum volume and the lack of deep bass compared to sealed earbuds. A few users note that in very quiet settings, sound leakage can be perceived by others nearby. The convenience of the open-ear design for safety and situational interaction, however, is a recurring and dominant theme in positive assessments.

Who Should Buy It (and Who Should Skip It)
The Shokz S803 is an excellent choice for outdoor athletes—particularly runners, cyclists, and hikers—who prioritize hearing traffic, other people, and their surroundings for safety. It’s also ideal for anyone who finds in-ear headphones uncomfortable or suffers from ear fatigue, or for users in work environments where they need to hear colleagues while listening to audio. Those managing tinnitus have also reported benefits.
These headphones should be skipped by audiophiles seeking rich, immersive bass and pristine sound quality, or by users who need complete audio privacy in shared spaces. They are also not the right tool for swimming or activities involving full submersion. If your primary listening happens in quiet, stationary environments and noise isolation is desired, traditional over-ear or in-ear headphones, like those discussed in our tech gear reviews, will likely serve you better.
Final Verdict
The Shokz S803 OpenRun headphones successfully fulfill a specific niche. They are not a compromise but a deliberate engineering choice for safety and comfort during activity. The bone conduction technology works as advertised, delivering clear audio while keeping the ears free. The build quality, with its IP67 rating and ultra-light frame, is tailored to withstand demanding workouts. The included headband adds value by enhancing stability. For its target audience, the trade-off in bass response and absolute sound fidelity is more than justified by the gains in awareness and wearability.
When judged as a general-purpose headphone, it has clear limitations. However, as a specialized tool for fitness and situational awareness, it excels. If your audio needs align with outdoor activity, comfort over long periods, and maintaining a connection to your environment, the Shokz S803 is a compelling and highly effective solution. It represents a thoughtful application of technology to solve specific user problems, much like specialized tools in other fields, such as the resources we highlight in our cybersecurity guides.
FAQs
Can others hear my music when I’m using the Shokz S803?
In normal environments with ambient noise, the sound leakage is minimal and typically not noticeable to others. However, in extremely quiet settings like a silent room or library, people very close to you might be able to faintly hear what you are listening to. The bone conduction technology is designed for a private listening experience, but it is not as isolated as sealed earbuds.
Are the Shokz S803 headphones good for making phone calls?
Yes, call quality is listed as a key feature. The bone conduction microphone and audio technology are engineered for clear conversations. User reviews frequently praise the headphone’s performance for phone and voice calls, noting that the other party can hear them clearly even during outdoor activities.
Can I wear these with glasses or a cycling helmet?
The open-ear, behind-the-head design is generally compatible with both glasses and helmets. The thin titanium frame rests behind the ears, and the transducers sit on the cheekbones in front of the ears, which typically does not interfere with the arms of glasses or helmet straps. Many users specifically report using them successfully for cycling.
What is the difference between the OpenRun and the older Aeropex model?
According to the manufacturer’s information, the OpenRun is the new name for the product formerly known as Aeropex. The S803 model appears to be an update that comes with new packaging and includes the sports headband bundle. The core bone conduction technology and key specifications like battery life and IP rating seem consistent with the previous generation.
