How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want an open-ear fit with all-day battery and workout-ready water resistance, choose DEMICEA Open Ear Earbuds; if you need an in-ear pair with newer Bluetooth and on-stem touch control, choose Biyoso 5.4.
• DEMICEA Open Ear Earbuds — biggest strength: open-ear hooks with 30 hours of total playtime and IPX5 protection, so they stay put and keep going through long sessions.
• DEMICEA Open Ear Earbuds — biggest trade-off: the open-ear design means no noise isolation at all, and the noise-control field is listed as "None."
• Biyoso 5.4 — biggest strength: Bluetooth 5.4 with a semi-in-ear seal and stem-based touch control that includes swipe volume and a mute gesture.
• Biyoso 5.4 — biggest trade-off: just 4.5 hours per charge and roughly 20 hours with the case, with a much smaller 8 mm driver.
• Who each pick is for: DEMICEA for runners, gym-goers and anyone who wants to hear their surroundings; Biyoso for commuters and call-takers who want sound funneled into the ear canal.
The DEMICEA set is built around the idea that you should never have to jam anything into your ear canal. Each bud weighs 0.26 ounces and hangs on a 0.77 mm titanium alloy frame wrapped in silicone, so it rests against the outside of your ear rather than plugging it. That hook shape is the whole point: it survives sweat, head movement and long wear without the pressure feeling you get from in-ear tips. The enclosure is a mix of metal, plastic and silicone, finished in beige, and the charging case matches.
Inside, DEMICEA uses 15 mm oval acoustic units paired with what the brand calls AeroDirect directional sound field technology, which is meant to push audio toward your ear and limit leakage. There's also AeroBoost digital enhancement aimed at making vocals sound more lifelike. The frequency range is listed at 10 Hz to 10,000 Hz — narrower at the top end than the Biyoso's 20 kHz ceiling, which tells you these are tuned for warmth and voice rather than sparkly treble detail. Two MEMS microphones with directional pickup and ClearTalk noise-cancelling handle calls, and Bluetooth 5.3 keeps latency under 60 milliseconds.
Battery is where DEMICEA runs away with it. A single charge is rated for 10 hours, and the case brings the total to 30 hours. The case itself has an 80-hour standby figure, an 0.4 Ah cell, a 2.5-hour recharge time and a 2-hour charge time for the buds. IPX5 covers the whole body with a hydrophobic treatment on the mic and speaker grilles — sweat and splashes are fine, full submersion is not.
Buy it if you run, lift, do yoga, or want to keep an ear on traffic and coworkers while music plays. Skip it if you fly a lot or work in a loud open office — with noise control listed as None, there is nothing here to block a jet engine or a busy café.
The Biyoso X61 takes the opposite approach. These are in-ear buds — the spec sheet calls the shape "In-ear" and the design "semi-in-ear" — so they sit at the entrance of the canal and physically block some outside sound. That's passive noise cancellation, and it's the only kind you get here; there's no active system. Each bud weighs just 4.26 g, the lightest figure in this comparison, and the set ships in white with a silver case.
Control is the marquee feature. Biyoso puts touch control on the stem: swipe up or down for volume, press once to play, pause, or mute and unmute on a call, press twice to end a call, and hold to cycle listening modes. If you've ever fumbled for your phone mid-run to change volume, that swipe gesture is genuinely useful — it's the kind of thing inline and stem controls exist for.
The audio hardware is smaller: 8 mm dynamic drivers, 32 ohms impedance, 90 dB sensitivity, and a 20 Hz to 20 kHz frequency range. That's a wider stated range than the DEMICEA, and the higher impedance means they'll draw a bit more power for the same loudness. Connectivity is Bluetooth 5.4, the newer standard here, with a 10-meter range and auto-pairing when you open the case. The mic is rated at -42 dB ± 3.
The catch is runtime. Biyoso rates 4.5 hours of music at 80% volume, about 3 hours of call time, 60 hours of standby, and roughly 20 hours total across three case recharges. The case tops up in 1.2 hours via USB-C. Both the buds and the case are IPX5, so sweat and rain are covered.
Buy it if you commute, take a lot of calls, and want volume control without touching your phone. Skip it if you need marathon battery life or you dislike the plugged-up feeling of in-ear tips.
Side-by-Side: Which Should You Choose?
• Best for battery life → DEMICEA Open Ear Earbuds. 10 hours per charge and 30 hours with the case versus 4.5 and roughly 20.
• Best for situational awareness → DEMICEA Open Ear Earbuds. Open-ear means traffic, gym announcements and conversations stay audible.
• Best for newer Bluetooth → Biyoso 5.4. Bluetooth 5.4 versus 5.3, with auto-pairing on case open.
• Best for on-device control → Biyoso 5.4. Swipe volume and press-to-mute on the stem beat tapping blindly at a bud.
• Best for passive noise blocking → Biyoso 5.4. The semi-in-ear seal does what an open-ear design structurally cannot.
• Best for call clarity in noisy places → DEMICEA Open Ear Earbuds. Dual MEMS mics with directional pickup and ClearTalk noise cancelling are aimed squarely at voice pickup.
• Best for a discreet, light fit → Biyoso 5.4. At 4.26 g per bud, they nearly disappear.
In my opinion, the DEMICEA Open Ear Earbuds are the safer buy for most people. The 30-hour total runtime, IPX5 body coating and hook fit solve the two things that actually ruin earbuds in daily life: running out of charge and falling out. The Biyoso 5.4 is the better pick only if you specifically want an in-ear seal and stem controls — the Bluetooth 5.4 and swipe gestures are real advantages, but 4.5 hours per charge is a short leash. If you're still weighing it, check the current price on Amazon before deciding, since that's the one variable specs can't settle for you.
FAQ
It means the earbud surface acts as a button. On the DEMICEA set, control is listed as touch control via a touch controller. On the Biyoso, touch control sits on the stem — swipe for volume, press to play or pause, double-press to end a call, hold to switch modes.
Neither the DEMICEA nor the Biyoso data sheets list a lockout or disable function, so there's no documented way to switch touch control off on either model. If accidental taps are the problem, the practical workaround is to adjust volume and tracks from your phone instead and handle the buds only by the edges.
Because touch-control earbuds send commands over the Bluetooth connection — a tap is a play/pause signal, a swipe is a volume signal. Both of these models do exactly that by design, which is why a stray brush against a bud or stem can pause your music.
In my opinion the DEMICEA Open Ear Earbuds, because the earhook frame, 0.26 oz per bud weight and IPX5 sweat protection are all built for movement. The Biyoso is also IPX5, but its 4.5-hour rating and in-ear seal make it less suited to long outdoor sessions where you want to hear what's around you.
