How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want pocket-sized true wireless earbuds with an IPX8 waterproof rating and a chipset built for low-latency listening, choose KMOUK True; if you need over-ear headphones with a wired fallback cable, memory foam cushions and a bigger 40mm driver, choose SLuB Headphones Over Ear.
• KMOUK True — biggest strength: true wireless freedom in a 50g package, IPX8 waterproofing, Qualcomm QCC3040 Bluetooth 5.2 and 30 hours of total playtime with the charging case.
• KMOUK True — biggest trade-off: in-ear only, no wired backup, and the noise control field is listed as None — isolation comes purely from the silicone tips.
• SLuB Headphones Over Ear — biggest strength: over-ear memory foam comfort, a 40mm dynamic driver, Bluetooth 5.3 and a 3.5mm cable that keeps music going when the battery runs out.
• SLuB Headphones Over Ear — biggest trade-off: a full-size headset you fold and carry, with passive noise cancellation only and a 2-hour charge time.
• Pick KMOUK True if you want something tiny, sweat-resistant and split-able between one ear or two.
• Pick SLuB Headphones Over Ear if you want a sit-down headset for long desk, TV or gaming sessions with a cable safety net.
The KMOUK True is a classic true wireless earbud, and its design brief is clearly "go anywhere, do anything." The IPX8 rating is the headline spec here. That is a genuinely high water-resistance level for earbuds, and it is the reason I would point runners, gym-goers and anyone who trains outdoors toward this pair. Rain, sweat and a rinse under the tap are all within the design's stated intent.
Under the hood sits a Qualcomm QCC3040 chipset with Bluetooth 5.2, which the manufacturer describes as delivering faster connection, lower latency and wider compatibility. The practical detail I like is the independent-use design: you can run the left earbud, the right earbud, or both, without re-pairing. That is a real convenience for people who like one ear free while walking, driving-adjacent tasks or working in an office where they still need to hear a colleague.
Battery life is quoted at 6 hours per charge and 30 hours total with the case, which packs four extra charges. A full charge takes about 1.5 hours. The case weighs in at 50g, and the whole package is white with a rounded in-ear shape, touch controls, and two pairs of silicone eartips included. Compatibility covers Android, iOS and Windows devices over Bluetooth within roughly 10 metres.
Who should skip it? If you want a wired option for zero-latency monitoring, there is no 3.5mm jack here — connectivity is Bluetooth only. And if you want active noise cancellation, this is not that product; the datasheet lists noise control as None, so blocking out a noisy train carriage depends entirely on how well the tips seal. Passive isolation from a good in-ear fit is decent, but it is not the same thing.
The SLuB is the opposite philosophy: a full-size, foldable over-ear headset in khaki, built around comfort and staying power rather than portability. The memory foam ear cushions are the spec that matters most here. Memory foam wraps around the ear and is designed to hold its shape over long sessions, which is exactly what you want if you wear headphones for hours at a desk, in front of a TV or during a gaming session.
The audio side uses two 40mm dynamic drivers with a 20Hz–20,000Hz range — physically larger drivers than you get in any earbud, and the manufacturer frames them around "HD hi-fi" stereo sound. I would not over-read marketing language, but a 40mm driver in an over-ear enclosure is a fundamentally different listening experience from a small in-ear driver, particularly for bass presence and a sense of space.
Connectivity is Bluetooth 5.3 with a stated 10-metre range, and the included 3.5mm audio cable is the feature I would highlight to a buyer. When the battery dies, you plug in and keep going. That single cable turns a wireless headset into a wired one, which is a genuinely useful safety net on a long flight or a work-from-home day where charging slipped your mind.
Battery is quoted at about 30 hours of playback with a 2-hour charge time, and on iOS the remaining battery level can be shown in real time. Controls are push-button rather than touch, and the set folds for storage. Noise control is listed as passive cancellation — the physical seal of the ear cushions, not electronics. The box includes the headset, cables, a manual and a cartoon sticker. There is also a 1-year manufacturer warranty listed, and the model comes in five colour options, though this particular listing is khaki.
Who should skip it? Anyone who wants something that disappears into a pocket. This is a fold-and-carry headset, not a pocketable one. And if you specifically want active noise cancellation or a touch-control interface, this is not it — it is buttons and passive isolation.
• Best for workouts, running and rain → KMOUK True. IPX8 waterproofing plus a 50g case is the combination that makes sense for training.
• Best for long desk, TV and gaming sessions → SLuB Headphones Over Ear. Over-ear memory foam and 40mm drivers are built for sitting down and staying there.
• Best for using one ear at a time → KMOUK True. Left, right or both, with no re-pairing needed.
• Best when the battery might die mid-session → SLuB Headphones Over Ear. The 3.5mm cable keeps audio going; the KMOUK has no wired mode.
• Best for the newest Bluetooth spec → SLuB Headphones Over Ear. Bluetooth 5.3 versus 5.2 on the KMOUK.
• Best for charging speed → KMOUK True. Around 1.5 hours to full versus roughly 2 hours for the SLuB.
• Best for travel storage → SLuB Headphones Over Ear. It folds; the KMOUK case is small but the earbuds themselves have no folding trick.
• Best for passive isolation from a physical seal → SLuB Headphones Over Ear. Over-ear cushions cover more of the ear than silicone tips do.
• Best for pocket portability → KMOUK True. A 50g case versus a full headband.
If I had to pick one, I would buy the SLuB Headphones Over Ear. In my opinion, the combination of a 40mm driver, memory foam over-ear cushions and a 3.5mm cable makes it the more versatile product for the way most people actually listen at home or at a desk. The wired fallback alone removes the anxiety of a dead battery mid-task.
That said, this is not a universal answer. If your listening happens while moving — running, gym, commuting in the rain — the KMOUK True's IPX8 rating and true wireless design make far more sense, and I would recommend it without hesitation for that specific job. Two different tools, two different jobs.
FAQ
Yes. It ships with a 3.5mm audio cable, so you can connect to a computer, phone or tablet and keep listening once the battery is empty. The KMOUK True has no wired option.
Neither has active noise cancellation. The KMOUK True lists noise control as None, and the SLuB lists passive noise cancellation, meaning it relies on the physical seal of its ear cushions. Expect isolation, not electronic cancellation, from both.
Both are quoted at approximately 30 hours of total playtime. The KMOUK True gives about 6 hours per charge with the case providing four extra charges, while the SLuB runs roughly 30 hours continuously and charges in about 2 hours.
The KMOUK True, in my opinion. IPX8 waterproofing and a lightweight true wireless fit are designed for movement, while the SLuB's over-ear headband and memory foam cushions are aimed at stationary listening.
