OYIB’s black S75 is my pick among noise cancelling earbuds with ear hooks for call center work, pairing a secure over-ear fit with ENC call microphones. For stronger music-focused noise cancellation, TOZO is the alternative, with hybrid ANC and app-based EQ.
• OYIB Earbuds — best for workouts and long workdays; pick this if you want ear hooks, IPX7 water resistance, and a case with a battery display.
• OYIB Earbuds — best for a secure fit during exercise; pick this if the black S75’s stated 15-meter Bluetooth range and touch controls suit your routine.
• TOZO Crystal Pods Hybrid — best for focused listening and sound customization; pick this if hybrid ANC and app-based EQ matter more than ear hooks.
• EarFun Air Pro 3 — best for switching between work and personal devices; pick this if multipoint connection and adjustable ANC modes fit your setup.
The white OYIB S75 combines flexible silicone ear hooks with in-ear tips, a design aimed at staying in place through running, cycling, and gym sessions. Three tip sizes—small, medium, and large—give you options for adjusting the fit. Its IPX7 water-resistance rating is also a practical feature for workouts and rainy conditions.
For calls, the product specifies four ENC microphones and says they are intended to reduce background noise. That makes this a plausible option for someone taking calls from a home office, a commute, or a shared space. The listed Bluetooth 5.4 connection, automatic reconnection after initial pairing, and touch controls can also make day-to-day switching and call handling more convenient.
The battery claim is up to 8–10 hours per charge, with additional case capacity advertised for a total of up to 50 hours. A dual LED display shows the case and earbud battery levels, so you can check remaining charge at a glance. These features may appeal to someone who wants to avoid frequent charging during a workweek.
The main trade-off is that this model’s strengths center on fit, workout resistance, and call microphones—not on a stated hybrid ANC system for listening. ENC describes call-noise processing; it should not be treated as equivalent to active noise cancellation for music or general listening. I’d consider it for movement and calls, but not as the clearest choice for someone whose priority is blocking surrounding sound while listening.

This black version is also an OYIB S75 with silicone ear hooks, three tip sizes, Bluetooth 5.4, and a claimed IPX7 rating. Its listed core feature set is very similar to the white version: 13 mm drivers, ENC microphones, touch controls, and up to 50 hours of combined listening time with the case.
For call-center-style use, the manufacturer describes its microphones as using ENC to reduce background noise during calls. The product listing names common meeting and calling platforms, but the practical question for a buyer is whether a secure hook fit and hands-on controls suit a long shift. Touch controls are specified for calls and playback, while automatic reconnection is meant to reduce setup steps after the first pairing.
One detail that distinguishes this listing is its stated Bluetooth range of 15 meters. That could be useful if you need to move around while connected, though actual range depends on the surrounding environment and connected device. The listing also describes 8–10 hours per charge and a case that adds listening time, along with a display for checking battery levels.
The trade-off is familiar: call-focused ENC is not the same as hybrid ANC, and the listing does not specify a dedicated active-noise-cancellation system for listening. The black and white versions are close in stated design and core features, so I would choose between them based on the color you prefer and the listing details that matter to you—not assume a meaningful difference in sound or call performance.
TOZO’s Crystal Pods Hybrid are conventional in-ear earbuds, not an ear-hook design. Their main draw is hybrid active noise cancellation, which is intended to reduce surrounding noise during listening. If your priority is a quieter commute, focused music, or less ambient sound while working, that is a more directly relevant feature than the OYIB models’ call-focused ENC.
The earbuds use 10 mm dynamic drivers, and the TOZO app offers 32 EQ presets for adjusting sound. The product also specifies AI-assisted ENC call processing through its microphones. That combination gives buyers separate features to consider: hybrid ANC for listening, and ENC for voice calls. The clear charging case is a distinctive design detail, but the more practical reason to consider these is the listening and app customization.
TOZO lists up to seven hours per charge with ANC off, with the case providing additional charges for up to 70 hours total; with ANC on, the listed total is up to 60 hours. A 10-minute charge is stated to provide more than two hours of listening. Bluetooth 5.4 and touch-and-app controls round out a feature set aimed at music, calls, and travel.
The obvious compromise for this guide’s use case is the fit: there are no ear hooks. If secure over-ear support is essential for exercise or your preferred fit, these are a poor match despite their stronger stated listening-noise feature. In my view, they are the more relevant option for ANC-focused listening, but not for someone specifically shopping for earbuds with hooks.
EarFun’s Air Pro 3 also uses a conventional in-ear shape rather than ear hooks. Its main strengths are hybrid ANC with selectable modes, six microphones for call processing, and multipoint connectivity. Multipoint lets the earbuds connect to two devices at once and switch between them, which can help someone moving between a computer and phone during a workday.
The product specifies Qualcomm cVc 8.0 ENC for calls and hybrid ANC for listening, keeping those jobs distinct. It also offers app controls for EQ, noise-cancellation modes, and touch-control settings. The 11 mm drivers and aptX Adaptive support may interest people who prioritize audio features, though aptX Adaptive is not compatible with iOS devices.
Battery life is listed as up to nine hours per charge and up to 45 hours with the case. A quick 10-minute charge is said to provide two hours of listening, and the case supports wireless charging. Bluetooth 5.3 and a listed 55 ms latency round out the connectivity details for calls, video, and general listening.
The trade-off is again the lack of ear hooks. This model offers a more extensive set of listening and device-switching features than the hook-style options, but it may not provide the retention some shoppers want for running or active work. I would consider it for a desk setup with two devices, not as a direct fit for a buyer who specifically needs over-ear support.
How We Picked
We compared the listed fit designs, call-microphone features, noise-control modes, connectivity, and battery claims.
The ranking is our independent editorial opinion, based on how well each product’s stated features match the call-center use case.
They can be useful when a secure fit and call-focused microphone processing are priorities. The OYIB S75 listings specify ENC microphones, but ENC for calls is different from ANC for listening.
The OYIB listings describe ENC for reducing background noise during calls. They do not specify a hybrid ANC listening mode, so I would not treat them as equivalent to the TOZO or EarFun ANC models.
EarFun Air Pro 3 specifies multipoint connection for two devices. The OYIB models and TOZO list Bluetooth connectivity, but their provided feature details do not specify multipoint.
The provided specifications describe driver sizes, call microphones, Bluetooth features, and noise-control functions, but do not identify any of these as hi-res audio products. For call-center work, I’d focus first on fit, microphone processing, and how you’ll manage surrounding noise.
For a call center, I recommend the black OYIB S75 if ear hooks and a secure fit are the priority; choose TOZO instead if you want hybrid ANC for listening and do not need hooks.
