For rca earbuds touch, I recommend CMF BY NOTHING Buds 2a for nurses because its adjustable noise control, touch controls, and charging case make it the most flexible all-around pick.
Choose Sunffice instead if you need a single open-ear earpiece that leaves one ear uncovered for nearby conversations.
• CMF BY NOTHING Buds 2a — best for adjustable listening between shifts; pick this if you want in-ear ANC, touch controls, and app-based sound settings.
• Sunffice Single Open Ear — best for hands-free calls while keeping one ear open; pick this if you want a left-ear earpiece with up to 16 hours of continuous use stated.
• Sunffice Open Ear Headphone — best for long calls and active use; pick this if a rotating ear hook, either-ear fit, and stated IPX5 water resistance suit your routine.
• CMF BY NOTHING Buds 2a — best for a second color option; pick this if you want the same ANC and app features in Dark Grey.
The Light Grey CMF BY NOTHING Buds 2a are conventional in-ear wireless earbuds, with touch controls, Bluetooth 5.4, and active noise cancellation. Their 12.4 mm dynamic drivers are intended to give music a bass-forward character. The useful distinction here is flexibility: you can adjust ANC and sound settings in the Nothing X app, including choosing a transparency mode.
For nurses, that adjustability matters more than a promise of dramatic silence. The earbuds are designed to reduce ambient noise when you want to focus, while transparency mode offers a way to let more of the surroundings through. Neither feature replaces workplace safety procedures or the need to hear alarms and coworkers. In a clinical setting, I would use in-ear ANC selectively and keep situational awareness the priority.
The maker lists up to eight hours of earbud playtime and up to 35.5 hours with the case. A five-minute quick charge is stated to provide up to two hours of playback. Quad-microphone call processing includes environmental noise reduction and wind-noise reduction, which may help with calls in less-than-quiet places. Bluetooth 5.4 and Google Fast Pair are also listed, with Microsoft Quick Switch for compatible devices.

The trade-off is the in-ear fit. The package includes small, medium, and large tips, but an in-ear seal will not suit everyone, especially someone who wants to keep both ears open at work. IP54 is specified for the earbuds, but that should not be read as a guarantee against every exposure to moisture. In my opinion, this is the most versatile option here for someone who wants both listening control and a portable charging case.
This Sunffice is a single earpiece for the left ear, not a stereo pair. Its open-ear design sits outside the ear canal, leaving the ear uncovered. That makes it a more natural match for people who want to hear nearby conversation while taking a call or listening to audio. It uses Bluetooth 5.2 and is listed as compatible with iOS, Android, laptops, and tablets.
The maker states up to 16 hours of continuous call and music use, while the product information lists a 15-hour average battery life. Those figures are not identical, so I would treat them as manufacturer estimates rather than a guaranteed shift-long result. The stated charging time is one hour. At 0.35 ounces, it is described as lightweight, and its touch button handles basic operation.
For nurses, the appeal is straightforward: one ear remains uncovered, and the earpiece is intended for hands-free calls. That does not mean it belongs in every care environment; workplace rules and patient privacy still come first. The open design may also be preferable to an in-ear tip for someone who dislikes having an ear canal covered. Its stated 10-meter Bluetooth range gives room to move around a connected device, within that range.
The compromises are equally clear. It is left-ear only, so there is no option to wear it on the right ear according to the product information. It is a single earpiece, and the published specs do not describe the same app-based ANC adjustments or charging-case reserve as the CMF pair. I would choose it for simple, one-ear call use, not for someone looking for a pair of immersive music earbuds.
This Sunffice is also a single open-ear headset, but its hook can rotate for wear on either the left or right ear. Bluetooth 5.4 connects it to compatible phones, tablets, and computers, and touch controls are listed for managing audio and calls. Unlike an in-ear bud, it rests outside the ear canal, which leaves the surrounding environment audible.
The battery specification gives up to 28 hours of music playback and up to 35 hours of talk time. Those are stated maximums, not a promise that every workday will produce the same result. It also carries an IPX5 water-resistance specification, which the product description positions for sweat and rain. That can make it a practical candidate for active use, though it is still wise to follow the care guidance that comes with the product.
The rotating hook and either-ear fit make this model more adaptable than the left-only Sunffice. A nurse who wants one ear free for conversation may prefer this style over on-ear headphones for nurses, especially when a bulky headband would be inconvenient. Its advertised 10-meter wireless range is suitable for ordinary movement near a connected device, though walls and other conditions can affect a Bluetooth connection.
There are details I would not gloss over. This is one earpiece, not a stereo pair, and there is no charging case listed. In my opinion, it is the strongest Sunffice fit for someone who wants an open design, either-ear flexibility, and long stated talk time. Its main limitation is that it is a single-ear listening solution.
The Dark Grey version is the same basic CMF BY NOTHING Buds 2a design as the Light Grey model: in-ear wireless buds, Bluetooth 5.4, touch controls, 42 dB hybrid ANC, and 12.4 mm dynamic drivers. It also supports Nothing X app adjustments for ANC, transparency mode, and custom EQ. The color is the main stated difference between these two listings.
Its daily-use case is much the same. The stated battery life reaches eight hours for the earbuds and 35.5 hours with the case, and a five-minute quick charge is said to add up to two hours of playback. The app supports dual-device connectivity and a low-lag gaming mode. Those extras are useful for someone switching between compatible devices, although a nurse buying primarily for workplace calls may care more about fit, audio awareness, and local policies.
The earbuds include three tip sizes, which gives some room to find a suitable seal. Call features include four microphones and noise-processing features intended to improve voice clarity. For a quiet commute or personal listening away from work, the ANC and app controls offer more tailoring than either single-ear Sunffice model.
The central trade-off remains the same as with the Light Grey version: these are sealed in-ear earbuds, not open-ear listening devices. ANC can be useful in appropriate settings, but it can also make it harder to notice surrounding sounds. I would choose Dark Grey over Light Grey only if that is the color you prefer; the listed functional case for buying one rather than the other is otherwise essentially the same.
I compared the listed design, connectivity, controls, battery claims, water-resistance specifications, and call features.
The ranking reflects my independent editorial opinion, based on the needs each design appears to serve.

FAQ
Both Sunffice models are single earpieces. The Single Open Ear is specified for the left ear; the other Sunffice model has a rotating hook and is described as wearable on either ear.
The Sunffice Open Ear Headphone lists up to 28 hours of music playback and up to 35 hours of talk time. These are manufacturer-stated figures, so actual runtime can vary with use.
No. They are in-ear earbuds with active noise cancellation and a transparency mode. If keeping the ear canal uncovered is your priority, consider one of the single-ear Sunffice models instead.
Consider whether earbuds are allowed in the work area and whether you need to hear alarms, coworkers, or patients without delay. For nurses who need an ear open, I recommend considering the Sunffice Open Ear Headphone; for adjustable personal listening outside care duties, the CMF BY NOTHING Buds 2a offer more sound-control options.
