How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want all-day open-ear comfort with a charging case that keeps you untethered during long rides and runs, choose OHAYO Open Ear Headphones; if you need low-latency wired spatial audio for competitive FPS gaming on a console or PC, choose Rosmas Gaming Earbuds.
• OHAYO's biggest strength: a true wireless open-ear design with Bluetooth 5.4, an IPX6 rating and 40 hours of total playtime (10 in the buds, 30 from the case) — built for movement and long days away from a charger.
• OHAYO's biggest trade-off: no noise cancellation and an open design that deliberately lets the world in, so it won't isolate you on a loud train or give you a sealed, thumping low end.
• Rosmas' biggest strength: 360° spatial audio from custom-tuned 10mm drivers over a wired 3.5mm connection, which is exactly what competitive shooters want — no pairing, no lag, no battery to babysit.
• Rosmas' biggest trade-off: it's a wired in-ear with no wireless freedom and no water-resistance rating, so it's a desk-and-console tool rather than a gym companion.
• Who each is for: OHAYO suits cyclists, runners, gym-goers and commuters who want to stay aware of traffic and chatter; Rosmas suits PS5, Xbox, Switch and PC players who want directional audio and a mic for squad chat.
The OHAYO T10 hangs on your ear rather than sitting inside it. That hook-shaped, 8-gram-per-bud build is the whole point: nothing plugs your canal, so you keep hearing cars, bikes and voices around you. In my opinion that's the single most useful thing about this category, and OHAYO leans into it with an ergonomic earhook that's meant to stay put through running, cycling and workouts.
The audio hardware is more serious than the featherweight shell suggests. Each earbud runs a quad-speaker setup — dual drivers per side — anchored by 15mm dynamic drivers and a dedicated amplifier chip, with a rated 20 Hz–20 kHz range and 16-ohm impedance. OHAYO also claims anti-leak tuning that keeps output below 45dB at 30cm, plus a beamforming mic array with DSP that's designed to hold call clarity even in roughly 80dB of traffic noise. Bluetooth 5.4 handles the connection up to about 10 meters. The controls are touch-based rather than buttons — worth knowing if you've ever fought with a touchpad mid-sprint.
Battery life is the headline for everyday use: about 10 hours per charge, 30 more in the 500mAh case, and a one-hour top-up for the buds. The IPX6 rating means sweat, rain and splashes are fine. There's a smart digital display on the case, and the package includes the case, a USB-C cable and a manual, backed by a one-year warranty.
Buy it if you want awareness-first listening for cycling, running, workouts and commutes, and you'd rather not think about charging every day. Skip it if you need active noise cancellation, a fully sealed fit for deep bass, or a wired connection for competitive gaming — this is the wrong tool for all three.
The Rosmas TM01 goes the other direction entirely: it's a wired in-ear aimed squarely at gamers. The 3.5mm plug means plug-and-play on PS5, Xbox, PC, Switch, laptops and any phone with a headphone jack — no drivers, no pairing, no charging. For anyone who has lost a ranked match to Bluetooth audio delay, that wired connection is the feature, not a compromise.
The tuning is built around 360° spatial audio from custom-tuned 10mm dynamic drivers. Rosmas frames this as a competitive advantage — hearing footsteps and reloads directionally so you can react faster in FPS titles. I can't verify how any individual hears it, but the design intent is clear: positional cues over bass thump. The 45° angled in-ear fit with soft silicone tips in S/M/L is meant to keep the seal comfortable across long sessions, and the housing mixes aerospace-grade aluminum with plastic for a bit of durability.
Controls are refreshingly old-school: an in-line module handles volume and call management without pausing your game, and there's a built-in HD microphone for voice chat. The reinforced braided cable resists tangling, and the L-shaped plug is shaped to survive daily plugging and unplugging. Rosmas backs it with an 18-month warranty and a stated returns-and-exchanges policy.
Buy it if you game on a console or PC, want zero-latency directional audio, and value a mic plus inline volume. Skip it if you need wireless freedom, water resistance for sweaty training, or any kind of noise cancelling — none of those are on the spec sheet.
• Best for battery life and wireless freedom → OHAYO Open Ear Headphones (10 hours per charge, 30 in the case, Bluetooth 5.4).
• Best for competitive gaming and low latency → Rosmas Gaming Earbuds (wired 3.5mm, 360° spatial audio, no pairing delay).
• Best for running, cycling and workouts → OHAYO Open Ear Headphones (open-ear awareness, IPX6, secure earhooks).
• Best for voice chat during games → Rosmas Gaming Earbuds (built-in HD mic and in-line controls).
• Best for staying aware of traffic and surroundings → OHAYO Open Ear Headphones (nothing blocks your ear canal).
• Best for plug-and-play across consoles and PC → Rosmas Gaming Earbuds (PS5, Xbox, Switch, PC, laptop, no drivers).
• Best for long listening sessions without ear fatigue → OHAYO Open Ear Headphones (8g per bud, no in-canal pressure).
• Best for noise isolation → neither — OHAYO is deliberately open and Rosmas has no noise control, so if you need to block out a plane cabin, look elsewhere.
If I had to pick one for most people, I'd take the OHAYO Open Ear Headphones. The case gives you 40 hours of total playtime, the IPX6 rating covers real sweat and rain, and the open-ear fit solves the one problem that ruins earbuds for cycling and running: not hearing what's around you. I'd only steer you to the Rosmas Gaming Earbuds if gaming is the actual job — a wired 3.5mm connection with spatial audio and an inline mic is simply the more sensible setup for a PS5 or PC, and no amount of Bluetooth 5.4 changes that. Two different jobs, two different answers. Buy for the job you actually do.
That depends on what you need. OHAYO's spec sheet stands out for the dual-driver-per-earbud setup, 15mm drivers, a dedicated amp chip, Bluetooth 5.4, IPX6 and a 40-hour total with the case. If those features map to how you'd use them, it's a coherent package — check the current price on Amazon and judge it against your own priorities.
I wouldn't recommend it. The data sheet lists no water or sweat resistance rating, and the wired braided cable is designed for a desk or console setup, not movement. The OHAYO's IPX6 rating makes it the better fit for training.
You can use them for casual game audio, but the open-ear design and Bluetooth wireless connection aren't built for competitive play — there's no low-latency wired mode listed and the mic array is tuned for calls in noisy environments rather than voice chat. For ranked FPS play, the wired Rosmas is the more logical choice.
On paper, OHAYO, because it's the only one of the two with a described call system: a beamforming mic array with DSP gain that's designed to hold clarity in loud surroundings. Rosmas has an HD mic, but it isn't positioned as a call-focused product.
No. The Rosmas uses a standard 3.5mm jack and the manufacturer states plug-and-play compatibility with PS5, Xbox, PC, Switch and laptops. As long as your device has a 3.5mm port, you just plug in.
