If you want a true pair of open-ear earbuds with spatial audio, a charging case and all-day battery for long hospital shifts, choose XKDUN Open Ear Headphones; if you need one ultra-light single earbud you can flip between ears for calls and quick audio, choose SVJEFY Single Bluetooth5.4. I get asked about this exact pair a lot by nurses hunting for comfortable clip-on style earbuds that stay put through a 12-hour shift, so let me break down what the spec sheets actually tell you.
• XKDUN Open Ear Headphones — biggest strength: a genuine stereo pair with 16.2mm titanium-coated drivers, LDAC support and a 30-hour total battery figure, so you get real music separation and a charging case that tops you up on the go.
• XKDUN Open Ear Headphones — biggest trade-off: it's a two-earbud setup, so you're wearing something on both ears, and the case adds bulk to a pocket or scrub bag compared with a single bud.
• SVJEFY Single Bluetooth5.4 — biggest strength: one 12g earbud with a 180° rotating hook that swaps between left and right ears, plus a 26-hour single-charge battery and Bluetooth 5.4.
• SVJEFY Single Bluetooth5.4 — biggest trade-off: it's mono audio only, there's no charging case, and it's built for calls and simple listening rather than immersive music.
• Who each pick is for: XKDUN for anyone who wants full stereo sound and a case; SVJEFY for anyone who wants the lightest possible one-ear setup and prefers leaving one ear completely open.
The XKDUN Open Ear Headphones are built around a 16.2mm dynamic driver with a titanium-coated diaphragm and a 20Hz–20,000Hz frequency range, which is the kind of hardware you'd normally associate with a full earbud rather than an open-ear hook. Because the buds sit outside the ear canal and fire sound directionally, you keep your surroundings audible — a real plus on a hospital floor where you need to hear a call bell, a colleague, or an alarm while something plays quietly in the background. LDAC support matters here too: it's a higher-bitrate Bluetooth codec, so if your phone supports it, music has more detail than a basic SBC stream.
The fit is an ear-hook design in beige plastic, with soft, gentle-finish hooks that hold position during movement. IPX6 water resistance covers sweat and rain, which matters if you walk to and from work or squeeze in a run — just don't soak them or swim in them. Touch controls handle playback and calls.
Who should buy it: nurses and other shift workers who want music and clear calls in both ears, want a case to top up mid-shift, and want to stay aware of what's happening around them. Who should skip it: anyone who specifically wants one ear free at all times, or who dislikes touch controls and would rather have a physical button. If you're comparing this against traditional headband headphones for nurses, the open-ear hook is the lighter, less pressure-prone option — no band pressing on your head under a scrub cap.
SVJEFY Single Bluetooth5.4: Who It's For
The SVJEFY Single Bluetooth5.4 is a different philosophy entirely: one earbud, 12g total, with a 180° rotating ear-hook that lets you wear it on the left or right ear depending on which side you want free. That single-ear format is the whole point. You keep one ear completely unobstructed for talking to patients, hearing overhead pages, or listening for traffic on a bike — the kind of awareness that dual-earbud wearers give up. It's covered in a soft, skin-friendly ABS material, and the hook is shaped to sit on a range of ear shapes without pressing into the canal, since nothing enters your ear at all.
Audio is air conduction through a composite diaphragm and a large dynamic coil, with a low-distortion sound cavity. It's tuned for clarity over thump — fine for podcasts, audiobooks, calls and casual music, but it won't match a stereo pair for imaging or bass. The sixth-generation directional sound transmission is claimed to cut sound leakage by 93%, which is the feature that actually matters in a shared space: your call audio stays in your ear instead of broadcasting to the break room.
Battery is 26 hours from a single 180mAh cell on one charge, with USB-C refilling it in about an hour. There's no case — the earbud itself is the whole product, plus a manual and a charging cable. The LED display shows real-time remaining power, and the standby figure is quoted at 365 days. Controls are a single multi-function button rather than touch, which is easier to operate by feel with gloves or a lanyard. Bluetooth 5.4 is the newer spec here, with universal compatibility across Android, iOS and Windows. It's sweat and water resistant, so workouts and light rain are fine.
Who should buy it: people who only ever want one ear covered — drivers, cyclists, warehouse and floor staff, and anyone who takes a lot of calls and wants the lightest thing possible hanging off their ear. Who should skip it: anyone who wants stereo music, a charging case, or a spare earbud in the box.
• Best for stereo music and real sound quality → XKDUN Open Ear Headphones, thanks to the 16.2mm titanium-coated driver and LDAC support.
• Best for maximum awareness and one-ear-only wear → SVJEFY Single Bluetooth5.4, since the 180° hook flips between ears and leaves the other ear wide open.
• Best for total battery per charge → SVJEFY Single Bluetooth5.4 at 26 hours on one cell, versus XKDUN's 8 hours per charge.
• Best for total battery with a case → XKDUN Open Ear Headphones at 30 hours combined, with a 400mAh case and a real-time LED readout.
• Best for the lightest possible fit → SVJEFY Single Bluetooth5.4 at 12g; XKDUN carries two buds plus a 53.7g case.
• Best for calls in noisy places → XKDUN Open Ear Headphones, which pair built-in noise-cancelling microphones with sound isolation.
• Best for privacy in public → SVJEFY Single Bluetooth5.4, whose directional transmission is designed to cut leakage dramatically.
• Best for touch-free, button-simple control → SVJEFY Single Bluetooth5.4; XKDUN uses touch controls instead.
For nurses specifically, I'd buy the XKDUN Open Ear Headphones. The case-and-stereo combination is what actually survives a long shift: 30 hours of total playback means you're not rationing audio, the LED readout tells you where you stand, and the noise-cancelling mics keep handoff calls clear in a loud corridor. If your priority is keeping one ear completely free and you mostly take calls rather than listen to music, the SVJEFY is the smarter, lighter pick — but for me, the XKDUN is the better all-rounder for shift work.
In my opinion the XKDUN suits nurses better because it gives you two earbuds, a charging case and 30 hours of combined playback. The SVJEFY wins if you specifically need one ear left completely open all shift.
Both use ear-hook designs rather than tips in the canal. XKDUN uses soft, gentle-finish hooks; SVJEFY uses a 12g hook that rotates to fit either ear. Neither relies on a seal, so there's nothing to loosen as your ear canal warms up.

Yes. XKDUN carries IPX6 water resistance for sweat and rain, and SVJEFY is sweat and water resistant. Neither is meant for swimming or being soaked.
