If you want a sealed in-ear fit with serious sweat protection for hard training sessions, choose Otium Headphones; if you need open-ear comfort, all-day environmental awareness and a much longer total battery reserve, choose Conyat Open-Ear Headphones.
• Otium Headphones — biggest strength: IPX7 water resistance plus a sealed in-ear design with four eartip sizes (XS, S, M, L) and soft earhooks, which is exactly what a sweaty gym or running session demands.
• Otium Headphones — biggest trade-off: The in-ear seal blocks your surroundings, and the battery is listed at 9 hours of average life, so long days away from a charger need planning.
• Conyat Open-Ear Headphones — biggest strength: Roughly 6.7g per earpiece with an open-ear hook design and a 40-hour total reserve with the charging case, so it can stay on your head from morning to night.
• Conyat Open-Ear Headphones — biggest trade-off: Nothing plugs your ear canal, so you get less isolation and less low-end thump than a sealed in-ear bud can deliver.
• Who each pick is for: Otium for the runner or lifter who wants a locked-in, waterproof in-ear fit; Conyat for the cyclist, commuter or office worker who wants to hear traffic, colleagues and announcements while music plays.
The Otium set is a sport-first in-ear headphone, and the spec sheet reads like it was written by someone who has watched a pair of earbuds die in a puddle of sweat. The headline number is IPX7 water resistance — that is the rating tier you want when the plan is running, jogging, hiking, yoga, gym work or training in the rain, because the nano-coating is there specifically to stop moisture from reaching the internal components. Combine that with soft silicon earhooks and four eartip sizes, and you have a fit system designed to survive burpees, sprints and a towel-down without shifting.
Sound-wise, Otium leans on a dynamic driver covering 20 Hz to 20,000 Hz, with the tuning described as bass-forward and crisp up top. Because it is a sealed in-ear design, that bass has somewhere to build — which is the whole appeal if you want music to carry you through a set. Battery is listed at 9 hours of average life, with a 1.5-hour charge time and a full-charge light indication, plus the battery status showing up on your phone screen. There is a carrying case in the box, and the controls are physical buttons for skip, play, pause and calls, so you are not fishing your phone out mid-workout.
Buy it if you want a locked-in, waterproof in-ear headphone for training and you are fine charging it every few days. Skip it if you wear earbuds all day long, need to stay aware of traffic or coworkers, or want a big reserve in a charging case — the sealed fit and 9-hour figure work against you there.
The Conyat X5S is the opposite philosophy: nothing enters your ear canal at all. Instead, the earpieces hook over your ears and sit at roughly 6.7g each, which is the kind of weight you forget about after a few minutes. If you have ever pulled a sealed bud out after two hours and felt that pressure release, this is the design built to avoid exactly that. It is aimed at sports, running, commuting and daily wear, and the ergonomic contour is the reason it can stay on through a long day.
The real selling point is situational awareness. Because your canal stays open, you can hear cars, bikes, announcements and people talking to you while music or a call plays — genuinely useful when cycling, walking, running or even driving. Conyat pairs that with a 14.2mm dynamic driver and directional sound transmission meant to reduce leakage, so what you are listening to does not broadcast to everyone around you. For calls, there is an ENC noise-cancelling microphone that focuses on your voice and pushes background noise down, which matters in an office or on a busy street.
On endurance, the numbers are strong: 8–10 hours per charge, extended to 40 hours total with the case, a 1.5-hour USB-C recharge, and an LED display on the case showing battery status so you are not guessing. Bluetooth 6.0 handles pairing and stability, and controls are touch-based for power, playback, track skipping, calls and volume. IP7 water resistance covers sweat and rain.
Buy it if you want all-day comfort, awareness of your surroundings and a long total reserve. Skip it if you crave deep isolation or maximum bass impact in a noisy gym — an open design simply cannot seal out the world the way an in-ear can.
• Best for maximum sweat and water protection → Otium Headphones. IPX7 plus nano-coating is the more aggressive stance for heavy sweating and rain.
• Best for all-day comfort → Conyat Open-Ear Headphones. Around 6.7g per earpiece with an unobstructed ear canal is hard to beat over long stretches.
• Best for total battery reserve → Conyat Open-Ear Headphones. 40 hours with the case versus a 9-hour average life on the Otium.
• Best for bass impact and isolation → Otium Headphones. The sealed in-ear fit with four eartip sizes is what gives low-end its punch.
• Best for cycling, commuting and staying aware → Conyat Open-Ear Headphones. The open design keeps traffic and surroundings audible.
• Best for calls in noisy places → Conyat Open-Ear Headphones. The ENC microphone is tuned to pull your voice out of background noise.
• Best for a secure fit during intense movement → Otium Headphones. Earhooks plus selectable eartips are built to hold through sprinting and lifting.
• Best for a modern connection and touch controls → Conyat Open-Ear Headphones. Bluetooth 6.0 and touch control versus the Otium's physical buttons.
In my opinion, the Conyat Open-Ear Headphones are the better everyday pick for most people. The combination of roughly 6.7g per earpiece, situational awareness, a 40-hour reserve and an ENC mic covers commuting, running, calls and office work in one product — that is a lot of ground for a single set of earbuds. I would only steer you to the Otium Headphones if your priority is a sealed, bass-forward in-ear fit that is explicitly rated for heavy sweat and rain. If you train hard and want the music locked in, Otium is the one; if you want to wear them all day and still hear the world, go Conyat. Either way, check the current price on Amazon before you commit.
Both handle running. Conyat keeps you aware of traffic and lasts far longer on a charge, while Otium gives you a sealed, bass-heavy fit with IPX7 protection. Pick based on whether you want awareness or isolation.
The design points that way: IPX7 water resistance, soft silicon earhooks and four eartip sizes (XS, S, M, L) are all aimed at keeping the fit secure through intense training.
Otium lists 9 hours of average battery life with a 1.5-hour charge. Conyat lists 8–10 hours per charge and up to 40 hours total with the charging case.
Conyat has the edge on paper thanks to its ENC noise-cancelling microphone, which is designed to filter out background noise. Otium also has a built-in mic with voice notification of incoming calls.
