• Otium Headphones — biggest strength: a complete, self-contained set of IPX7 sweat- and water-resistant in-ear sports earbuds with earhooks, four eartip sizes, a carrying case and on-ear controls.
• Otium Headphones — biggest trade-off: the battery life is modest (9–10 hours of play per charge, roughly 1.5 hours to refill), so heavy all-day users will be charging often.
• LIAUBN iClever BTH12 — biggest strength: a durable 5-foot USB-C to USB-A charging cable rated for fast charging up to 2 A, built to survive thousands of insertions and bends.
• LIAUBN iClever BTH12 — biggest trade-off: it is a cable, not a headphone — it produces no sound and only works with USB-C devices, not Micro-USB ones.
• Choose Otium if you want headphones to actually listen with, especially for running, gym work and sweaty outdoor sessions.
• Choose LIAUBN if you already own a USB-C over-ear headphone and just need a reliable spare or replacement charger.
The Otium set is built around one clear idea: keep the earbuds in your ears while you move. The rounded-tip in-ear design ships with earhooks and four eartip sizes (XS, S, M and L), so you can dial in a fit that stays put through running, jogging, hiking, yoga or a gym session. That combination of earhook plus correct eartip size is what separates a workout earbud from a general-purpose one, and it is the part of this design I would pay the most attention to if you have ever had buds pop out mid-run.
The headline spec is the IPX7 water-resistance rating. Otium describes a nano-coating that keeps sweat and water from reaching the internal components, which is why this model is pitched at workouts in the sun and music in the rain. If your current earbuds die every few months from sweat damage, that rating is the reason to look here.
Where it gets weaker is stamina. The sheet lists around 9 hours of average battery life and up to 10 hours of music per full charge, with a 1.5-hour charge time and a full-charge light indicator. It also lists up to 15 hours of talk time and 250 hours of standby. None of that is bad for a compact sport bud, but it is not all-day battery. Frequent flyers or people who want to wear one pair from morning to night should expect to top up.
Who should buy it: runners, gym-goers and anyone who wants a lightweight (20 g), sweat-proof in-ear set with a case, earhooks, multiple eartip sizes and button controls for play, pause and track skipping. Who should skip it: anyone who wants over-ear cups, a huge battery, or the simplest possible wired setup.
LIAUBN iClever BTH12: Who It's For
Here is the thing that trips people up: despite the name, the LIAUBN iClever BTH12 is a charging cable. Specifically, it is a 5-foot USB-C to USB-A cable supplied with a small adapter, and it is sold as a replacement charger for over-ear Bluetooth headphones that charge over USB-C — the listing names MOVSSOU E7 and SE8, DOQAUS, HROEENOI, KVIDIO, BERIBES, Tuitager, Uliptz, INFURTURE and the iClever BTH12 itself.
The build is the selling point. LIAUBN rates the heat-resistant aluminium connector for more than 10,000 insertions and the tangle-free cable for 12,000 bends. Those are durability claims aimed at the exact failure point of cheap charging cables — the joint where the plug meets the cord. If you have gone through three anonymous cables in a year, a cable with a stated bend and insertion rating is a genuinely sensible upgrade.
Charging performance is listed at up to 2 A with a 10-watt rating and a 24-pin connector, which the listing frames as fast charging for Bluetooth headphones and other USB-C devices. The cable also supports data sync, not just power. It is a male-to-male round cable, black, and weighs about 0.06 kg.
Who should buy it: anyone whose USB-C over-ear headphones, including the models named above, have lost or damaged their charging cable, or who wants a longer 5-foot cable for charging on a sofa or in bed. Who should skip it: anyone shopping for headphones, and anyone with a Micro-USB device.
Side-by-Side: Which Should You Choose?
• You want actual headphones → Otium Headphones. The LIAUBN item cannot play audio.
• You need a replacement charging cable for USB-C over-ear headphones → LIAUBN iClever BTH12.
• Best for sweaty workouts and running → Otium Headphones, thanks to the IPX7 rating, earhooks and four eartip sizes.
• Best for durability of the product itself → LIAUBN iClever BTH12, with its rated 10,000 insertions and 12,000 bends.
• Best for battery life → neither is a standout, but Otium offers roughly 9–10 hours of playback plus 250 hours of standby; the cable has no battery at all.
• Best for charging speed → LIAUBN iClever BTH12, rated up to 2 A / 10 W.
• Best for fit and portability → Otium Headphones, at 20 g with a carrying case and an optional wire clip.
• Best for compatibility flexibility → Otium Headphones, since Bluetooth works with essentially any phone; the cable only fits USB-C ports.
In my opinion, these are not competing products, and the honest answer is that your choice is decided before you start comparing. If you are shopping for headphones, I would buy the Otium set: it is a complete, purpose-built sports earbud with an IPX7 rating, earhooks, four eartip sizes, a case and on-ear controls, and its 9–10 hours of playback is reasonable for gym-length sessions. I would only pick the LIAUBN iClever BTH12 if I already owned a USB-C over-ear headphone and needed a tougher replacement cable — its durability ratings and 2 A charging are exactly what you want in that role. Buying the cable when you need headphones, or the headphones when you need a cable, is the only real mistake here.
No. It is a 5-foot USB-C to USB-A charging cable with an adapter, sold as a replacement charger for over-ear Bluetooth headphones and other USB-C devices. It does not play audio.
Only if your headphones charge over USB-C. The listing states clearly that it is not a Micro-USB cable, so check your charging port first. It is listed as compatible with MOVSSOU E7 and SE8, DOQAUS, HROEENOI, KVIDIO, BERIBES, Tuitager, Uliptz, INFURTURE and the iClever BTH12.
Yes — that is the point of the IPX7 rating. Otium describes a nano-coating that blocks sweat and water from reaching the internal components, and the design is marketed for running, hiking, yoga, gym work and travel.
The Otium Headphones, without question — the LIAUBN cable has no audio function. Otium uses dynamic drivers covering 20 Hz to 20,000 Hz with a bass-forward tuning, plus a built-in mic for calls. Just keep in mind its battery is around 9–10 hours per charge. If price matters to your decision, check the current price on Amazon before you commit.
