Let’s take a closer look at what makes these wireless earbuds stand out.


The BONSORION 03 earbuds connect via Bluetooth 5.3 to your device for seamless wireless listening.

The BONSORION 03 earbuds feature a sleek, low-profile design that is both stylish and discreet. The all-black color scheme lends them an understated, neutral look suitable for any activity. The earbud itself is compact and lightweight, with most of the surface area occupied by the exterior touch controls. This minimalist styling allows the earbuds to sit flush to the ear without bulky protrusions. The ear clip arm extends at a gentle curve to provide a secure yet comfortable grip around the contours of the ear.

Ease of Use

Overall, the 03 earbuds are quite easy and intuitive to operate. The touch controls are responsive to taps and swipes, allowing you to control music playback and calls without reaching for your phone. Bluetooth pairing is quick and seamless with most devices. The earbuds automatically turn on and connect when removed from the case, then turn off and charge when returned. The open ear design negates any need to adjust or fiddle with eartips for insertion. Just slide on and go.

Build Quality

Constructed from durable ABS plastic, the 03 earbuds feel sturdy and well-built. While not indestructible, they can likely withstand being tossed in a gym bag and the occasional accidental drop. The IPX5 water resistance rating means they are resistant to sweat, sprays, and light rain, though not fully waterproof. The matte black finish resists scratches and scuffs. Overall quality is impressive considering the affordable price point.

Audio Performance

Thanks to the bone conduction drivers, audio reproduction is balanced and clear, though lacking in thumping bass. Maximum volume may be inadequate in very loud environments. Call quality is serviceable but prone to background noise interference. The open ear design prevents noise isolation/cancellation, allowing ambient sound to be heard. On the whole, audio quality is decent for casual listening and workouts, but audiophiles may desire more refinement and power.

Battery Life

True to specifications, the 03 earbuds deliver outstanding battery life of up to 8 hours continuous playback on a single charge. Including the portable charging case, you can expect up to 32 hours before needing to recharge via USB-C. This level of battery endurance is hard to match at any price point, and easily beats most competitors. You may be able to use the 03 earbuds for days without charging.


Equipped with the latest Bluetooth 5.3, the 03 earbuds have excellent wireless connectivity and range. Pairing is quick and simple with compatible devices that support Bluetooth protocols. You can roam 30+ feet away from your phone while still maintaining a solid connection. Multiple paired devices are supported. Wired use is not possible since there is no headphone jack.

Onboard touch controls allow you to play/pause, skip tracks, adjust volume, answer calls and activate your phone’s voice assistant. The touch sensors are responsive to taps, double taps, and swipes. Learning the gesture patterns takes a bit of practice but soon becomes second nature. Physical buttons would be easier to operate, but touch controls help maintain the sleek, seamless design.

Use Cases

With their unique bone conducting design, the BONSORION 03 earbuds are optimally suited for sports and workouts. Runners can pump up their pace with motivational music and still hear traffic for safety. Yogis flow through sun salutations while listening to chill vibes in the park. Gym-goers crush HIIT workouts fueled by heavy bass and still chat with trainers. The open ear style keeps you connected to your surroundings while the wireless freedom allows movement unfettered by cords. Lightweight and stable, they’ll stay firmly in place even when you’re working up a sweat. For music lovers and fitness buffs alike, these earbuds are perfect workout partners.

User Feedback Analysis

Customer opinions on these budget-friendly open ear earbuds are resoundingly mixed, oscillating between glowing praise and scathing criticism. Based on hundreds of reviews across retail sites, the listening masses are clearly divided.

For audio aficionados seeking sonic perfection, the prevailing sentiment is that you get what you pay for. While the 03s certainly won’t match the pristine audio reproduction of premium brands costing 10 times as much, those keeping expectations in check found the sound quality surprisingly decent and enjoyable, especially for casual listening and pumping up workouts.

When it comes to battery life, users are blown away by the endless endurance. The ability to keep listening for days without charging makes these earbuds road trip and travel favorites. Whether binging podcasts on a cross-country flight or jamming to playlists on long backpacking adventures, the 03s have the juice to go the distance.

Comfort and fit are where opinions diverge. Those with average to large ear sizes reported the earbuds stayed firmly in place during intense activity and vigorous workouts thanks to the well designed ear clips and tips. However, wearers with smaller ears complained of looseness and constant need for readjustment as the 03s slowly slid out of the optimal position over time.

Features like the IPX5 sweat resistance rating make these great gym and running partners in any weather. Touch controls earned nods for responsiveness and ease of learning. Phone call quality, however, was panned as subpar by many customers. Background noise cancellation is basically non-existent thanks to the open ear design.

When viewed through the lens of unrealistic expectations, the 03s disappoint. But taken for what they are - an affordable pair of basic wireless earbuds - most find these audacious bone conduction earpieces to punch well above their ultra-low weight class and price tag.

Pros and Cons

- Great value and low cost
- Very long total battery life
- Bone conduction technology works well
- Open ear design allows situational awareness

- Ear clips can slide out of position
- Maximum volume may be too low for some

For around $12 USD, the BONSORION 03 earbuds provide a lot of bang for your buck. The ability to wirelessly stream audio for up to 8 hours on a charge is impressive given the price point. Add in the portability of the charging case with its extra 24 hours of power, and you’ve got a budget set of earphones you may be able to use for days without plugging in. While the sound and call quality aren’t going to beat more premium brands, they perform admirably considering the cost. For a dirt cheap way to pump up your workouts with your phone’s playlists, these earbuds will do the job just fine.


With their unique bone conduction design, Bluetooth wireless functionality, secure sporty style and lengthy battery life, the BONSORION 03 Open Ear Headphones are a compelling choice. For just over $12, they deliver good audio and versatility for sports and active lifestyles. Just keep in mind you may need to adjust the fit and positioning to optimize the wearing experience.
