• Biggest strength of the ACEFAST AceFit Pro Open-Ear: a genuinely sport-first design — open-ear ear hooks, 40 built-in LED safety lights for night visibility, IP54 resistance and a 30-hour total battery with a digital display case.
• Biggest trade-off of the ACEFAST AceFit Pro Open-Ear: no active noise cancellation and no in-ear seal, so you hear your surroundings (which is the point for running, but not for blocking out a noisy commute).
• Biggest strength of the ZIUTY Earbuds: an unusually feature-dense package — hybrid ANC rated to cut up to 40dB, a transparency mode, 5 EQ presets, IPX7 waterproofing and a touchscreen charging case with 10+ functions.
• Biggest trade-off of the ZIUTY Earbuds: it's a traditional in-ear bud, so comfort depends on tip fit, and the touchscreen case adds bulk and complexity you may not want mid-run.
• Choose the ACEFAST AceFit Pro Open-Ear if you're a runner, cyclist or gym-goer who wants awareness, a secure ear-hook fit and night visibility.
• Choose the ZIUTY Earbuds if you want immersive listening, long battery life and hands-on control from the case itself.
The AceFit Pro is designed around one idea: stay aware, stay comfortable, stay seen. It uses an open-ear ear-hook shape rather than a sealed in-ear bud, so nothing is jammed into your ear canal. The hook is built from an ultra-thin 0.7mm nickel-titanium memory wire that adapts to your ear shape — and ACEFAST specifically notes it works for glasses wearers, which is a small detail that matters a lot if you run in prescription frames. At roughly 7.8g per bud with a supramolecular liquid silicone coating, the whole pitch is all-day comfort rather than maximum isolation.
Buy it if you want open-ear awareness, night-time visibility and a fit that survives sweat and movement. Skip it if you mainly want to shut the world out on a plane or a loud train — with no ANC and no ear seal, that's simply not what this product is for.
ZIUTY Earbuds: Who It's For
The ZIUTY Earbuds go the opposite direction: pack in as much technology as possible. The headline feature is the charging case, which has a responsive touchscreen and more than 10 built-in functions. From the case alone you can skip tracks, change volume, locate a misplaced earbud, or even trigger your phone's camera shutter. That's a genuinely different way of controlling earbuds — you're not fishing for a touch panel on the bud itself, and for some people that's a big usability win.
Audio and noise control are the second pillar. A 14.2mm dynamic driver handles playback with 5 EQ presets to tune the sound, and hybrid Active Noise Cancellation is rated to cut up to 40dB of ambient noise. A transparency mode flips the other way so you can hear announcements or traffic with a tap. Calls get dual-ENC microphones that ZIUTY says remove 98% of background noise, which is the kind of spec aimed at people taking meetings in cafes. Battery is rated at up to 8 hours per charge and 40 hours total with the case, and a 10-minute quick charge is quoted at 2 hours of playback. Water resistance is IPX7 — a stronger rating than the ACEFAST's IP54 — and Bluetooth 5.3 with 55ms latency is tuned for gaming and video. You get three ear-tip sizes (S/M/L), USB-C and wireless charging, and this model comes in Pink.
Buy it if you want noise cancellation, long battery, immersive sound and a control hub built into the case. Skip it if you need to hear your surroundings for safety, or if you'd rather not deal with a screen-equipped case during a sweaty workout.
• Best for running at night → ACEFAST AceFit Pro Open-Ear. The 40 LED lights and 10-meter visibility claim exist for exactly this.
• Best for noise cancellation → ZIUTY Earbuds. Hybrid ANC rated to block up to 40dB, plus a transparency mode when you want back in.
• Best for battery life → ZIUTY Earbuds. 40 hours total versus the ACEFAST's 30 hours.
• Best for open-ear awareness and comfort → ACEFAST AceFit Pro Open-Ear. No ear-canal sealing, memory-wire hooks and a glasses-friendly fit.
• Best for water and sweat resistance → ZIUTY Earbuds. IPX7 beats IP54 on paper.
• Best for calls in noisy places → ZIUTY Earbuds. Dual-ENC mics with a 98% background-noise reduction claim.
• Best for gym and outdoor workouts generally → ACEFAST AceFit Pro Open-Ear. The whole product is built for movement, switching devices and quick top-ups.
• Best for control flexibility → ZIUTY Earbuds. The touchscreen case handles volume, tracks, camera and lost-buddy finding.
In my opinion, the right pick comes down to one question: do you want to hear the world or shut it out? If you're a runner, cyclist or outdoor trainer, I'd buy the ACEFAST AceFit Pro Open-Ear — the open-ear design, memory-wire hooks, LED safety lights and 30-hour battery are all aimed at exactly that job, and the app control and dual-device switching keep it practical day to day. The ZIUTY Earbuds are the better choice if you want ANC, a longer 40-hour total runtime, IPX7 and a case that does half the controlling for you. For sport and safety, I'd go ACEFAST. For immersive listening and battery, I'd go ZIUTY.
For running, I'd lean ACEFAST. The open-ear hook design keeps you aware of traffic, the memory-wire hooks are built to stay put, and the LED lights add visibility after dark. The ZIUTY's IPX7 rating is tougher against water, but sealed in-ear buds block out the surroundings many runners want to hear.
Correct. ZIUTY lists hybrid ANC rated to block up to 40dB plus a transparency mode. The ACEFAST AceFit Pro Open-Ear has open-ear acoustics with no noise control — its design goal is awareness, not isolation.
ZIUTY quotes up to 8 hours per charge and 40 hours total with the case. ACEFAST quotes 30 hours total, with a 5-minute charge giving roughly 2 hours of playtime. If total runtime is your priority, ZIUTY wins on the numbers.
Both sit in the same general category, so the deciding factor is features rather than anything I can quote here. Check the current price on Amazon for each, then match it to what you actually need: open-ear safety and comfort (ACEFAST) or ANC, battery and touchscreen control (ZIUTY).
