How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a lightweight open-ear clip design that keeps you aware of traffic and your surroundings while you run, cycle or skate, choose Boytond Open Ear Earbuds; if you need serious battery life, waterproofing and a secure ear-hook fit for long gym sessions, choose Faxoimu Earbuds.
• Boytond's biggest strength: a true open-ear, clip-on design (over-ear placement) that leaves your ear canal open, so you stay aware of traffic, gym noise and people around you — plus a 5-minute quick charge and 10 hours of playback.
• Boytond's biggest trade-off: no noise control at all and no water-resistance rating listed, so loud environments and heavy sweat or rain are not what it was built for.
• Faxoimu's biggest strength: a claimed 120 hours of total playtime with the charging case, IPX7 waterproofing and a wrap-around ear hook that locks onto the ear during hard training.
• Faxoimu's biggest trade-off: it is a sealed in-ear design with a charging case and a heavier footprint (111.6 g total), so you lose the open-ear awareness that makes Boytond appealing.
• Who each pick is for: Boytond for awareness-first runners, cyclists and all-day light listeners; Faxoimu for gym-goers, hikers and long-trip users who want maximum runtime and sweat protection.
Boytond's whole pitch is the shape. These are open-ear buds that clip over the ear rather than plug into it, which means nothing sits inside your ear canal. In practice that changes how you use them: you can still hear a car coming up behind you on a bike, a coach calling out a set, or a colleague walking up to your desk. That awareness is the reason open-ear designs exist, and it is Boytond's clearest advantage.
The spec sheet backs up the comfort angle too. The enclosure is thermoplastic elastomer, the carrying case is silicone, and the whole thing is built around an over-ear clip. The driver is a 16.3 mm dynamic driver covering 20Hz–20,000Hz, which is a standard full-range setup, and the touch controls let you tap rather than fumble with buttons mid-stride. Battery is listed at 10 hours of average life with a 5-minute charge time, so a short top-up gets you moving again. Bluetooth range is 10 meters, which is normal for a phone-in-pocket or phone-on-bench setup.
Who should buy it: runners, cyclists and skaters who ride or train near traffic, anyone who wants music or calls without blocking out the world, and people who find in-ear tips uncomfortable after an hour. Who should skip it: if you want active noise cancellation, Boytond has none — the noise control field is literally "None." There is also no water-resistance rating listed, so I would not treat these as a rain or pool companion. And if you want the deepest possible bass isolation, a sealed in-ear design will always beat an open one.
Faxoimu goes the opposite direction: it is a fully sealed, ear-hook sports earbud built around runtime and durability. The headline number is 120 hours of total battery life with the charging case, plus a 1-hour quick charge that supports 14 hours of single-bud playback. For anyone who has ever had buds die halfway through a long hike or a double gym session, that is the feature that matters most.
The rest of the spec sheet reads like a checklist for hard training. Bluetooth 6.1 with auto-reconnect when you open the case, a claimed 49 ft of range, a 16.2 mm dynamic driver paired with ENC and CVC 8.0 dual noise reduction, and an IPX7 waterproof rating that the brand says survives 1 m of water immersion for 30 minutes. The ergonomic ear hook is designed to lock onto both small and large ears, so slipping during running or lifting should not be the failure point. Controls are a simple push button — switch tracks, adjust volume, answer calls, wake your voice assistant — which is easier to hit with sweaty hands than a touch surface.
Two things to weigh honestly. First, this is an in-ear, sealed design, so you are trading the open-ear awareness of Boytond for isolation and bass. Second, it is a heavier, more involved kit: 111.6 g with the charging case, cable, eartips and manual included. That is fine in a gym bag, less ideal if you want something you forget you are wearing.
Who should buy it: gym regulars, hikers, long-distance travellers and anyone whose priority is "charge it once, forget about it." Who should skip it: cyclists and runners who specifically want to hear their surroundings, and anyone who dislikes the feeling of an in-ear seal.
Side-by-Side: Which Should You Choose?
• Best for battery life → Faxoimu Earbuds. 120 hours total with the case and 14 hours per single charge is in a different league from Boytond's 10 hours.
• Best for sweat and rain → Faxoimu Earbuds. The IPX7 rating is the only water-resistance figure on either sheet; Boytond lists none.
• Best for quick top-ups → Boytond Open Ear Earbuds. A 5-minute charge time is genuinely handy when you are heading out the door.
• Best for call clarity in noisy places → Faxoimu Earbuds. ENC and CVC 8.0 dual noise reduction is built for gyms, commutes and office calls.
• Best for comfortable all-day wear → Boytond Open Ear Earbuds. Silicone case, TPE body and no in-ear pressure make long listening sessions easier.
• Best for touch-free, glove-friendly control → Faxoimu Earbuds. Physical push buttons beat touch taps when your hands are wet or gloved.
• Best for a compact everyday carry → Boytond Open Ear Earbuds. One item, a silicone case, no cable or eartip swapping to think about.
In my opinion, Faxoimu Earbuds are the safer buy for most people shopping this comparison. The 120-hour total battery life, IPX7 waterproofing and locked-in ear hook solve the three problems that actually end workouts early: dead batteries, sweat damage and buds falling out. Boytond is the better pick only if open-ear awareness is your non-negotiable — and if it is, it does that job well with a genuinely comfortable clip design. If you are purely a gym and travel user, I would go Faxoimu. Check the current price on Amazon before you decide, since that is the one variable I cannot compare here.
FAQ
By the listed figures, yes. Faxoimu claims 120 hours total with the charging case and 14 hours per single charge, while Boytond lists 10 hours of average battery life with a 5-minute charge time.
Faxoimu, clearly. It carries an IPX7 waterproof rating and is described as sweatproof and rainproof. Boytond lists no water-resistance rating, so I would keep it out of heavy sweat and rain.
Boytond Open Ear Earbuds. The open-ear clip leaves your canal unobstructed, so conversations, traffic and gym announcements come through. Faxoimu seals the ear for isolation and bass instead.
