Updated: 2026-09-30 · 7 min read · Independent comparison
• ACREO Next — biggest strength: A true open-ear build with ear hooks, a 6-hour single-charge playtime (18 hours with the case), and a Hi-Fi-oriented acoustic design aimed at runners who want to stay aware of their surroundings.
• ACREO Next — biggest trade-off: No noise cancellation and a Bluetooth 4 spec, so it's an awareness-first headphone rather than an isolation-first one.
• Faxoimu Earbuds 120H — biggest strength: Up to 120 hours of total playback with the case, a dual LED battery display, and Bluetooth 6.1 for stable pairing.
• Faxoimu Earbuds 120H — biggest trade-off: Call time drops to roughly 3–4 hours per charge, and the in-ear, behind-the-ear design means you're sealed off from ambient sound.
• Who ACREO Next is for: Runners, cyclists, and outdoor athletes who want open-ear awareness plus IPX7 durability.
• Who Faxoimu Earbuds 120H is for: Commuters, travelers, and gym-goers who want maximum battery life, deep bass, and don't mind an in-ear fit.
ACREO Next is the pick for anyone who's tired of jamming silicone tips into their ears. It's an open-ear wireless earbud with ear hooks, which means the driver sits outside your ear canal and the hook keeps it locked in place. The result is a fit that stays stable through running, biking, and outdoor sports — and, just as importantly, you can still hear a car coming up behind you. For road runners, that awareness matters more than raw isolation.
The sound side is where the spec sheet gets interesting. ACREO built this around standalone headphone amplifiers rated up to 6W total (2×3W) with a 103dB signal-to-noise ratio, driving a 32-ohm dynamic driver with a 20 Hz–20,000 Hz frequency range. In plain terms, that's a design meant to push a genuinely powerful sound field without the bone-conduction buzz some open-ear models produce. There's also a low-latency mode you trigger by pressing an earbud button four times — useful for video and gaming, though the brand notes connectivity performance dips slightly in that mode.
Battery is 6 hours per charge and 18 hours total with the case, and the case itself supports wireless charging plus smart sensing. The earbuds can be used one at a time and pair automatically. On durability, ACREO uses a dual approach — structural waterproofing plus nano-technology — to reach the IPX7 rating, which the brand frames as sweat-proof, splash-proof, and rainproof.
Faxoimu Earbuds 120H: Who It's For
Faxoimu Earbuds 120H is built around one number: 120. That's the total playback time when you count the charging case. The earbuds themselves run 8–10 hours of music per charge, and the case stretches that to 120 hours. The brand is upfront about a catch worth repeating — if you're using them for calls, expect closer to 3–4 hours per charge. That's a real difference between music and talk time, and it's the kind of thing that actually matters if you take a lot of meetings.
Charging is handled over USB-C, and the case goes from empty to full in about 2 hours. There's also a dual LED digital display on the case showing real-time battery status, which sounds like a small thing until you've owned a pair of earbuds that died mid-run with no warning. Faxoimu also recommends a full charge before first use.
On the tech side, these run Bluetooth 6.1 — the newest version in this comparison — with automatic reconnection to the last paired device, so you set it up once and forget it. The drivers are 14.2mm Hi-Fi units tuned for deep bass and clear highs. Controls are physical buttons rather than touch, which I actually prefer for workouts: you can play/pause, skip tracks, adjust volume, and handle calls without swiping at your ear with sweaty fingers. Compatibility covers most Bluetooth devices — phones, tablets, laptops.
The fit is in-ear with a behind-the-ear hook, and Faxoimu markets it specifically for running, yoga, gym sessions, and rainy conditions. The IPX7 rating matches the ACREO here, so on waterproofing these two are genuinely level.
Who should skip it: If you want to hear your surroundings while you run, the in-ear seal works against you. If call quality over long stretches is your priority, the 3–4 hour call figure is a limitation to weigh. And if you dislike the feeling of tips inside your ears, the open-ear alternative will suit you better.
• Best for battery life → Faxoimu Earbuds 120H. 120 hours total with the case versus 18 hours on the ACREO Next.
• Best for outdoor awareness and safety → ACREO Next. The open-ear design lets ambient sound in while the ear hooks keep it stable.
• Best for bass and immersive listening → Faxoimu Earbuds 120H. 14.2mm Hi-Fi drivers explicitly tuned for deep bass.
• Best for running, biking, and outdoor sports → ACREO Next. Open-ear plus dual waterproofing (structural + nano-technology) built for sweat and rain.
• Best for commuting and travel → Faxoimu Earbuds 120H. Long playback, LED battery display, and automatic reconnection make it a low-maintenance travel companion.
• Best for calls → ACREO Next. It uses a noise reduction algorithm the brand compares to business Bluetooth headsets, and calls don't suffer the 3–4 hour per-charge drop that Faxoimu notes.
• Best for the newest Bluetooth and easiest pairing → Faxoimu Earbuds 120H. Bluetooth 6.1 with auto-reconnect outpaces the ACREO's Bluetooth 4.
• Best for a fully sealed fit → Faxoimu Earbuds 120H. In-ear with behind-the-ear hooks, versus ACREO's deliberately open design.
In my opinion, the right call comes down to how you'll use them most. If you're a runner or cyclist who wants to hear the world around you and hates ear tips, I'd buy the ACREO Next — the open-ear build, ear hooks, and call-focused noise reduction algorithm fit that life better. If you want maximum battery, deep bass, and a sealed in-ear fit for the gym or a long commute, I'd buy the Faxoimu Earbuds 120H. Both are IPX7, so waterproofing isn't the deciding factor. Check the current price on Amazon before you commit, since that's the one variable I can't weigh in for you.
FAQ
are ipx7 earbuds waterproof
IPX7 is a waterproofing standard that means the device can survive immersion in water up to a specified depth for a limited time. Both the ACREO Next and Faxoimu Earbuds 120H carry this IPX7 rating, so both are designed to handle sweat, rain, and splashes without issue.
can you shower with ipx7 earbuds
Faxoimu Earbuds 120H wins clearly on this one. It offers up to 120 hours of total playback with the case, versus 18 hours for the ACREO Next. Just remember the Faxoimu's call time drops to about 3–4 hours per charge.
The ACREO Next lists noise control as "None" but includes a noise reduction algorithm for calls, so voices come through clearly without blocking your surroundings. The Faxoimu Earbuds 120H doesn't list active noise cancellation either, and its in-ear seal naturally blocks more ambient sound.
