If you want superior battery longevity, a more robust driver configuration for immersive audio, and a longer warranty for peace of mind, choose HAKII Open Ear; if you need the absolute lightest possible feel for all-day video calls, a dedicated app for EQ customization, and a compact case that slips easily into small pockets, choose Oraolo Open Ear AC210.
• HAKII Open Ear: Best in class for extended battery life (18 hours total) and advanced connectivity features like multi-device switching via its app, though it lacks active noise cancellation. Ideal for runners and remote workers who need long sessions without recharging.
• Oraolo Open Ear AC210: Stands out with dual 12mm drivers and beryllium diaphragms for richer sound, plus a massive 30-hour total battery life, but offers a simpler feature set without an accompanying mobile app. Perfect for users prioritizing audio fidelity and durability over smart features.
• The Verdict on Fit: Choose HAKII if your workflow demands custom sound profiles and seamless switching between work devices; pick Oraolo if you simply want high-fidelity open-ear audio that lasts through multiple days of heavy use.
The HAKII Open Ear is engineered specifically for the person who lives their life on the go and needs their headphones to be as invisible as they are effective. Weighing just 7.5 grams per earbud, these clip-on headphones utilize a flexible titanium core wrapped in soft silicone. This design ensures that even after hours of wear, there is no pressure on the auricle. For someone attending back-to-back video calls or managing a busy day of errands, this feather-light construction means you can forget the device is even there. The ergonomic fit is designed to stay put during intense physical activity, making it a top contender for those who need on-ear headphones for video calls while also hitting the gym.
Beyond comfort, the HAKII LINK model excels in versatility for the modern professional. It features Bluetooth 5.4 technology, which provides a rock-solid connection with ultra-low latency. While it does not offer active noise cancellation—a trade-off inherent to its open-ear design—it utilizes Environmental Noise Cancellation (ENC) to ensure your voice comes through clearly on calls. The inclusion of a dedicated mobile app is a significant differentiator. Through this app, you can access personalized EQ modes, enabling you to tailor the bass and treble to your specific preference. You can also manage multi-device switching and locate lost earbuds. If you frequently toggle between a laptop for work and a phone for personal tasks, the ability to switch seamlessly between sources is a game-changer.

However, this level of sophistication comes with specific limitations. The HAKII only supports one device connection at a time unless you manually manage it through the app, and the battery life, while respectable at 6 hours on a single charge and 18 hours total with the case, falls short of some competitors. Additionally, the charging case is compact, measuring just 7 centimeters in length, which makes it pocket-friendly but limits the internal battery capacity compared to bulkier models. If you are looking for a headphone that adapts to your hearing preferences and handles complex workflows, the HAKII is built for you. If you prefer a "set it and forget it" approach with minimal software interaction, you might find the app requirements unnecessary.
The Oraolo Open Ear AC210 targets the audiophile who values raw sound quality above all else, paired with extreme endurance. This model distinguishes itself immediately with its driver technology. Unlike standard dynamic drivers, the AC210 employs dual 12mm units equipped with modified PI composite beryllium diaphragms. When combined with a dedicated DAC sound card providing 30mW thrust, the result is a three-dimensional, concrete soundscape that rivals many closed-back competitors. For someone seeking the best headphones for video calls where clarity and presence matter, this acoustic engineering ensures that voices are crisp and music retains its depth without the muffled feeling of traditional in-ear buds.
Battery life is arguably the most compelling argument for the Oraolo AC210. With up to 6 hours of playback on the buds alone and a staggering 30 hours when combined with the charging case, this unit is built for marathon usage. Whether you are traveling across time zones, working a double shift, or embarking on a long outdoor adventure, you will rarely need to hunt for a power outlet. The IPX5 waterproof rating adds another layer of reliability, ensuring that sweat and rain do not compromise performance. This makes it an excellent choice for anc sports earbuds for video calls scenarios where you might step from a heated office into a rainy commute without missing a beat.
The simplicity of the Oraolo design is both a strength and a limitation. It lacks the companion app found with the HAKII, meaning you cannot customize EQ settings or use voice commands for features like "Find My Earbuds." Instead, it relies on straightforward touch controls and Bluetooth 5.4 for connectivity. The absence of active noise cancellation is consistent with the open-ear category, but the ENC helps maintain call clarity. If you are someone who prefers a hardware-focused experience without navigating menus in an app, the AC210 delivers pure, unadulterated performance. It is particularly suited for users who prioritize the sheer duration of listening time and the richness of the audio output over smart features.
• Best for Battery Life → Oraolo Open Ear AC210: With a total of 30 hours of playback compared to HAKII's 18 hours, Oraolo wins decisively for long-haul users.
• Best for Custom Sound Profiles → HAKII Open Ear: Only the HAKII offers a dedicated app for EQ adjustments and personalized tuning.
• Best for Driver Technology → Oraolo Open Ear AC210: The dual 12mm beryllium diaphragms and DAC support provide a more premium, three-dimensional soundstage.
• Best for Multi-Device Switching → HAKII Open Ear: The app facilitates seamless switching between connected devices, whereas Oraolo requires manual re-pairing.
• Best for Pocket Portability → HAKII Open Ear: At 7cm in length, the HAKII case is slightly more compact than the standard charging cases often found with higher-capacity batteries.
• Best for Durability & Warranty → Oraolo Open Ear AC210: Oraolo includes a 2-year warranty, doubling the protection period offered by HAKII's 1-year coverage.
• Best for Video Call Clarity → Tie: Both utilize ENC, but Oraolo's superior driver setup may offer slightly better voice reproduction for the listener.
• Best for Active Sports → HAKII Open Ear: The feather-light 7.5g weight and secure titanium core make it marginally less intrusive during high-intensity movement.
After weighing the specifications and real-world use cases, I would personally buy the Oraolo Open Ear AC210. The combination of 30-hour battery life and the sophisticated dual-driver beryllium system addresses the two biggest pain points for open-ear users: frequent charging and lackluster audio quality. While the HAKII offers nice software features, the Oraolo's hardware foundation feels more substantial for daily reliance. For anyone using on ear headphones for video calls as a primary tool, the Oraolo's superior sound stage and extended runtime provide a more professional and uninterrupted experience. In my opinion, having the best headphones for video calls means having audio that sounds rich enough to keep you engaged and a battery that lasts long enough to get through the entire week without anxiety.
No, neither model features Active Noise Cancellation (ANC) because they are open-ear designs intended to keep you aware of your surroundings. However, both utilize Environmental Noise Cancellation (ENC) microphones to isolate your voice during calls.
The Oraolo AC210 offers significantly more total playback time at 30 hours, while the HAKII provides 18 hours. If you travel frequently or have long workdays, the Oraolo reduces the frequency of needing to recharge the case.
The HAKII Link model allows for smart multi-device switching via its app, letting you move between a laptop and phone, though it generally maintains one active connection at a time. The Oraolo does not offer this app-based switching capability.
The Oraolo Open Ear AC210 comes with a 2-year warranty, offering double the protection period of the HAKII Open Ear, which includes a 1-year manufacturer warranty.
