If you want an open-ear design that stays comfortable for hours and keeps you aware of your surroundings, choose DUVOSS Earbuds; if you need true in-ear buds with a longer total battery figure and wireless charging, choose Groovz Plus True.
• DUVOSS Earbuds' biggest strength: an 11g-per-bud open-ear hook design that sits outside your ear canal, paired with a charging case that carries a 500mAh battery and an LED digital charge display.
• DUVOSS Earbuds' biggest trade-off: open-ear means less passive isolation — you hear more of the world around you, which is great on a run and less great on a noisy flight.
• Groovz Plus True's biggest strength: Bluetooth 5.4, dual microphones with noise reduction for calls, and a case that supports Qi wireless charging with an LED battery display.
• Groovz Plus True's biggest trade-off: it's an in-ear design, so it blocks more ambient sound — you'll want to be careful about awareness in traffic or on a bike.
• Who DUVOSS is for: runners, gym-goers and commuters who want their ears to stay open, sweat-resistant and pain-free over long sessions.
• Who Groovz Plus True is for: people who want a traditional sealed in-ear fit, stronger call clarity, and the convenience of dropping the case on a charging pad.
The DUVOSS Earbuds are built around one idea: keep the ear canal open. Each bud is an open-ear hook design with flexible silicone cushions and soft ear hooks, and it weighs just 11g per headset. That's the part that matters most if you've ever given up on earbuds because your ears ached after an hour. There's nothing pushing into your canal, so the fatigue that builds up during long calls or a two-hour gym session simply doesn't have the same trigger. If you wear earbuds while walking, cycling or lifting, the open design also keeps you aware of traffic, gym announcements and the people around you.
On the audio side, DUVOSS leans on a 16.2mm high-sensitivity diaphragm speaker with Liso2.0 bass enhancement, and the frequency range runs 20Hz to 20kHz with 104dB sensitivity and 22-ohm impedance. The company also uses DT3.0 directional sound transmission for calls, which is aimed at keeping your voice pointed at the mic rather than leaking everywhere. I'd frame the sound expectation honestly: an open-ear bud is not going to give you the same sealed, thumping bass feel as an in-ear model, but the large driver and bass enhancement are clearly there to compensate as much as physics allows.
The practical specs are solid. Bluetooth 5.3 with HSP, HFP, AVRCP and A2DP profiles, a ceramic antenna rated for 10m (33ft) range, and IPX4 water and sweat resistance with a steel mesh plus gauze mesh double-layer seal. Battery is 100mAh in the buds and 500mAh in the case, with 300 hours of standby, 12 hours of playback or 8 hours of talk time per charge, 1.5 hours to charge the buds and 2 hours for the case via USB-C. The case has an LED digital display so you can check state of charge at a glance. It ships with a charging cable, an instruction manual, a 2-year warranty, and a stated operating range of -40°C to 80°C. The ABS build and black finish are plain but purposeful.
Buy it if you want open-ear comfort, sweat resistance and long single-charge playback for workouts and commutes. Skip it if you mainly want to block out airplane or train noise, or you prefer a snug sealed in-ear fit with multiple ear tip sizes.
Groovz Plus True takes the opposite approach. These are in-ear buds with three ear tip sizes (S, M, L), so you can actually tune the seal to your ears — and a good seal is what gives an in-ear bud its bass and its noise blocking. The design is aimed at people who want their music to feel closed off from the world rather than mixed with it. It's a true wireless setup with touch controls on the buds and Bluetooth 5.4, which is a step newer than the 5.3 on the DUVOSS set. In practice that mostly means fast, stable pairing and the usual range you'd expect from a modern Bluetooth chip.
Calls are clearly a priority here. Groovz pairs dual microphones with noise reduction to cut down background sound, which is the setup you want if you take meetings from a coffee shop or a shared workspace. The case also carries an LED battery display and supports Qi-certified wireless charging — drop it on a pad and you're done, no cable hunting. The brand positions the buds for commutes, travel, workouts and work-from-home calls, and the color story is part of the pitch: the Oil Slick finish is meant to stand out, and the line offers a range of color options.
The battery structure is worth reading carefully. Groovz states up to 46 hours of total playtime, made up of the charging case plus 6.45 hours in the earbuds themselves. So the real-world rhythm is a bit under six and a half hours per charge, topped up repeatedly by the case — that's normal for true wireless, and the case is doing the heavy lifting. The buds are IPX4 water resistant, matching the DUVOSS rating, and they're compatible with both Apple and Android devices. Groovz also states the product is designed and engineered in the USA.
Buy it if you want a sealed in-ear fit, strong call clarity with dual mics, wireless charging convenience and a distinctive look. Skip it if you need to stay aware of your surroundings while running or riding, or you dislike anything sitting inside your ear canal for hours.
• Best for all-day comfort → DUVOSS Earbuds. At 11g per bud with open-ear hooks and no canal pressure, this is the design that won't make you want to take them out.
• Best for situational awareness → DUVOSS Earbuds. Open-ear means you hear traffic and surroundings; the Groovz in-ear seal does the opposite.
• Best for call clarity → Groovz Plus True. Dual microphones plus noise reduction is a more purpose-built call setup than a single directional transmission approach.
• Best for charging convenience → Groovz Plus True. Qi-certified wireless charging on the case beats plugging in a cable every time.
• Best for newest Bluetooth → Groovz Plus True. Bluetooth 5.4 versus 5.3 — a small but real generational gap.
• Best for long single-charge sessions → DUVOSS Earbuds. 12 hours of playback or 8 hours of talk time on one charge, with 300 hours of standby.
• Best for workouts and rain → a tie. Both carry an IPX4 water and sweat rating, so neither has a durability edge on paper.
• Best for fit customization → Groovz Plus True. Three ear tip sizes versus fixed silicone cushions.
If I had to pick one, I'd buy the DUVOSS Earbuds. In my opinion, the open-ear hook design at 11g per bud solves the single biggest reason people abandon earbuds — ear fatigue — and the 12-hour single-charge playback plus 500mAh case battery fit how I'd actually use them: workouts, walks and long work sessions where I still want to hear the room. The Groovz Plus True is the better pick if calls and wireless charging matter more to you than comfort, and it's a genuinely strong choice on those fronts. But for the widest range of everyday wear, DUVOSS wins for me.
Both are IPX4 water and sweat resistant, so both handle sweat and light rain. The difference is fit: DUVOSS's open-ear hooks keep your ears open to traffic and won't press on your canal, which most runners prefer. Groovz's in-ear seal blocks more noise, which some people want and others don't.
Which has the longer battery life?
Yes — the case supports any Qi-certified charging pad, which isn't included. That's a real convenience advantage over the DUVOSS case, which charges via USB-C only. If you already own a wireless charging pad, that's a point in Groovz's favor.
