If you want immersive sound, noise cancellation, and much longer stated battery life for motorcycle-related listening, choose TANCHJIM MINO ASANO Tench; if you need an open-ear design that leaves your ears unblocked, choose AYI Open Ear Air. For motorcycle use, neither should be treated as a substitute for hearing road sounds or following local rules on headphone use.
TANCHJIM MINO ASANO Tench vs AYI Open Ear Air at a Glance
• TANCHJIM MINO ASANO Tench strength: ANC, app controls, and up to 37 hours of standard-mode playback with the case. Trade-off: In-ear design blocks the ear canal, unlike AYI’s open-ear approach.
• AYI Open Ear Air strength: Air-conduction listening without blocking the ears. Trade-off: The supplied information gives no battery-life figure or app-based sound customization.
• TANCHJIM MINO ASANO Tench is for listeners who want adjustable, immersive in-ear audio and documented playback figures.
• AYI Open Ear Air is for listeners who prioritize an open-ear fit for outdoor activities and awareness of nearby sounds.
The Tench is an in-ear Bluetooth 5.3 earbud set built around a 10 mm dynamic driver. Its feature mix leans toward personal listening: active noise cancellation, transparency mode, call-noise reduction, game mode, and app controls. You can adjust equalizer settings and touch controls through the TANCHJIM app, which is compatible with iOS and Android.
Battery life is one of its clearest practical advantages. The earbuds are specified for up to six hours of playback in standard mode, with up to 37 hours total when the charging case is included. With noise cancellation enabled, the figures are up to five hours from the earbuds and up to 31 hours with the case. The case also supports USB-C and Qi wireless charging.
How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
I’d consider the Tench if you want to tune your listening, reduce background noise during stationary or indoor use, or have a stated battery figure to plan around. Its IPX4 rating covers sweat and light rain, but that is not a reason to assume it is suitable for immersion or heavy water exposure. For motorcycle use, its noise-blocking in-ear design is a real consideration: ANC may make surrounding traffic sounds less audible, so I would not choose it for listening while riding on public roads.
AYI Open Ear Air: Who It's For
The AYI Open Ear Air uses air-conduction audio and is designed to leave the ears unblocked. That makes it a different kind of choice from a sealed in-ear earbud. It may appeal to someone who wants to listen while remaining more aware of nearby sounds during outdoor activities, work, or exercise.
The supplied details list Bluetooth 5.4, a lightweight design, and IPX4 protection against sweat and light splashes. Those points suggest a straightforward option for everyday wireless listening and workouts. The information does not provide a specific battery runtime, driver size, app controls, noise-cancellation performance figure, or charging-case playback total, so it is difficult to compare those aspects directly with the Tench.
Choose AYI if the open-ear fit is your deciding factor and you want to avoid placing an earbud inside the ear canal. Skip it if you specifically need documented long playback, customizable EQ, or detailed call and latency features. For motorcycle use, open ears do not guarantee that you will hear every road sound; wind, traffic, helmet fit, and volume can all affect awareness.
• Best for a stated long battery figure → TANCHJIM MINO ASANO Tench. It specifies up to 37 hours with the case in standard mode, compared with no battery-life figure provided for AYI.
• Best for keeping the ears unblocked → AYI Open Ear Air. Its air-conduction design is the main reason to choose it over an in-ear model.
• Best for active noise cancellation → TANCHJIM MINO ASANO Tench. Its listed ANC reduction is up to -45 dB; AYI’s supplied details do not give a comparable ANC figure.
• Best for adjusting sound and touch controls → TANCHJIM MINO ASANO Tench. Its app supports EQ presets, custom settings, and configurable touch actions.
• Best for Bluetooth version → AYI Open Ear Air. It lists Bluetooth 5.4, while the Tench lists Bluetooth 5.3. The version number alone does not establish how either will perform in every setting.
• Best for a low-latency gaming mode → TANCHJIM MINO ASANO Tench. Its Game Mode is specified at 0.086 seconds.
• Best for sweat and light splashes → A tie on the stated rating. Both list IPX4 protection; neither should be treated as waterproof for swimming or submersion.
• Best fit for motorcycle-related listening → AYI Open Ear Air, with an important safety caveat. Its open-ear design better matches a preference for not blocking the ears, but it does not guarantee safe awareness while riding. Check local rules and avoid letting audio interfere with attention to the road.
The “best waterproof wireless headset for motorcycle” is not a claim I’d make for either of these: both list IPX4, which covers sweat and light splashes rather than immersion. Likewise, the Tench’s battery case makes it the more clearly specified option for long listening sessions, but no headphone should take priority over road awareness. A search for “rotatable ear cups wireless headphones for motorcycle” points to a different design question: neither product’s supplied details describe rotatable ear cups. These are earbuds and open-ear headphones, not over-ear models with documented rotating cups.
My Verdict
I’d choose the AYI Open Ear Air for motorcycle-related use if I had to pick between these two, because its open-ear design does not block the ear canal. For listening away from riding, I’d favor the TANCHJIM MINO ASANO Tench for its documented battery life, ANC, and app controls. Neither is my pick for a claimed “best waterproof” motorcycle headset.
AYI’s open-ear design is the closer match if you want your ears unblocked. That does not ensure you can hear traffic clearly in real conditions, and motorcycle headphone rules vary by location.
The Tench has stated figures: up to 37 hours with its case in standard mode, or up to 31 hours with the case when ANC is on. No battery runtime is provided for the AYI Open Ear Air, so a direct comparison is not possible.
Both list an IPX4 rating, which is intended for sweat and light splashes. That rating does not mean either product can be submerged or used for swimming.
The Tench lists ANC with noise reduction up to -45 dB, plus a transparency mode. The AYI information does not provide a comparable noise-cancellation figure, so there is not enough detail for a like-for-like performance comparison.
