If you want lightweight open-ear earbuds with earhooks and a long 40-hour total playtime for running, training and all-day wear, choose RICHJOY Open Ear Earbuds; if you need wired MFi-certified Lightning earphones with in-line controls and no charging or pairing at all, choose aceyoon MFi Certified iPhone.
• RICHJOY Open Ear Earbuds — biggest strength: an open-ear, over-ear hook design at roughly 7.5 grams per bud, with 40 hours of total playtime, Bluetooth 5.3 and an IP54 sweat/splash rating. Made for movement.
• RICHJOY Open Ear Earbuds — biggest trade-off: it's wireless, so it needs charging, and the open design deliberately doesn't seal off your ears — it won't isolate you the way an in-ear plug does.
• aceyoon MFi Certified iPhone — biggest strength: plug-and-play Lightning connection that's MFi certified for iPhone, iPad and iPod, with an in-line mic and volume remote. Nothing to charge, nothing to pair.
• aceyoon MFi Certified iPhone — biggest trade-off: it's a wired Lightning cable, so it only suits Apple devices with that port, and there's no battery flexibility to fall back on — the wire is always there.
• Who RICHJOY is for: runners, gym-goers, commuters and remote workers who want earbuds that stay put and keep going for days between charges.
• Who aceyoon is for: iPhone/iPad/iPod owners who want dependable wired audio and call control with zero setup and zero charging.
The RICHJOY Open Ear Earbuds are built around one idea: keep your ears open and your earbuds on. Each bud weighs about 7.5 grams, and flexible silicone earhooks wrap over the ear to hold them in place. That's the classic open-ear trade-off done deliberately — you get premium stereo sound pushed into the ear with directional audio technology that reduces leakage, but you don't get the sealed-off, plugged-up feeling of an in-ear tip. For a lot of people that's the whole point: you can hear your music and still hear traffic, a training partner, or a colleague walking up behind you.
The spec sheet backs up the active-lifestyle pitch. Bluetooth 5.3 handles pairing with iOS, Android and PC, and the buds auto power on when you open the case lid — the pairing name is "O300". Battery life is the headline number: up to 40 hours total, split between the buds and the charging case. That's the kind of figure that covers morning workouts, a full workday of calls and podcasts, and a multi-day trip without hunting for a cable every night. On the call side, the buds use environmental noise cancellation with AI-assisted ENC to filter wind, crowds and background chatter while focusing on your voice — handy if you take meetings outdoors or on a noisy street.
Buy these if you run, lift, cycle, commute or work remotely and want earbuds that stay put, stay comfortable for long sessions, and shrug off sweat and rain thanks to the IP54 rating. Skip them if you want total noise isolation, if you'd rather never think about charging, or if you specifically need a wired Lightning connection. The open design is a feature, not a flaw — but it is a genuine difference in how these sound and feel compared to sealed in-ears. In my opinion, the 40-hour playtime and 7.5-gram weight are the two numbers that matter most here, and both point to all-day, all-week wear. One more practical note: they come with a 1-year manufacturer warranty, and there's a documented reset routine (clear pairing, disable Bluetooth, case in/out, wait 20 seconds) if connection issues ever crop up.
The aceyoon MFi Certified iPhone earphones take the opposite approach entirely. These are wired Lightning in-ear buds, MFi certified for iPhone, iPad and iPod. There's no Bluetooth, no pairing, no battery, no case. You plug them into the Lightning jack and they work — plug-and-play with stable audio transmission. For anyone who has ever stood on a platform watching a pairing spinner, that simplicity is the entire appeal.
The design is an ergonomic in-ear shape with noise-isolating technology. Where the RICHJOY set lets the world in, these block ambient noise so you get a more immersive listen — better for a noisy bus, a plane, or an open-plan office where you want to disappear into a podcast. The in-line module gives you a microphone plus volume and remote buttons, so you can take and manage calls, skip tracks and adjust volume without touching your phone. The cable is built from durable, tangle-resistant materials meant to survive daily commuting, workouts and desk life, and the whole thing is finished in a clean white that matches Apple's own accessories.
Buy these if you own an iPhone, iPad or iPod with a Lightning port, you want zero charging anxiety, and you value noise isolation plus physical buttons over touch controls. Skip them if you're on USB-C, if you've moved to a phone without a headphone jack and don't want a wired tether, or if you want the freedom of a wireless set for running and gym work. A dangling cable is a real annoyance during heavy cardio, and it's the honest downside of this design. The aceyoon also carries a 1-year warranty. Note the spec sheet lists both a white finish in the title and a black color field — worth confirming the exact finish you want before ordering, since the two listings can look confusing side by side.
• Best for running, gym and outdoor training → RICHJOY Open Ear Earbuds. Earhooks plus IP54 sweat and splash protection, with nothing to snag or dangle.
• Best for noise isolation and focus → aceyoon MFi Certified iPhone. The in-ear seal blocks ambient sound; the open RICHJOY design intentionally lets it in.
• Best for battery life and freedom from cables → RICHJOY Open Ear Earbuds. Up to 40 hours total with the case, versus a wired set that never needs charging but never leaves your phone either.
• Best for zero setup and zero charging → aceyoon MFi Certified iPhone. Plug into Lightning and go; no pairing, no battery management.
• Best for calls on the move → RICHJOY Open Ear Earbuds. AI-assisted ENC targets wind, crowds and ambient noise while focusing on your voice.
• Best for physical buttons and volume control → aceyoon MFi Certified iPhone. Push-button in-line remote for calls, track navigation and volume.
• Best for iPhone/iPad/iPod owners who want a wired, certified connection → aceyoon MFi Certified iPhone. MFi certification is the compatibility guarantee here.
• Best for mixed devices (iOS, Android, PC) → RICHJOY Open Ear Earbuds. Bluetooth 5.3 pairs across platforms, so it isn't tied to one ecosystem.
If I had to pick one, I'd buy the RICHJOY Open Ear Earbuds. The combination of roughly 7.5-gram buds, flexible earhooks, up to 40 hours of total playtime, Bluetooth 5.3 across iOS/Android/PC and an IP54 rating covers more of my week than a wired set can — workouts, commutes, calls and long sessions, without worrying about charging or a cable catching on something. I'd only switch to the aceyoon MFi Certified iPhone if I specifically wanted wired, noise-isolating Lightning audio with physical buttons and no battery to think about. In my opinion the RICHJOY is the more flexible everyday pick, and the aceyoon is the more specialized, dependable one. Either way, check the current price on Amazon before you commit, since that's the one thing that can tip a close call.
Not universally — they solve different problems. RICHJOY wins on portability, battery life (up to 40 hours total), open-ear comfort and cross-device Bluetooth 5.3. The aceyoon wins on zero setup, MFi-certified Lightning compatibility and noise isolation. Pick based on whether you want wireless freedom or wired simplicity.
Do the aceyoon earphones need charging or Bluetooth pairing?
The RICHJOY Open Ear Earbuds, in my opinion. The silicone earhooks and open-ear fit keep them secure, the IP54 rating handles sweat, rain and splashes, and there's no cable to tangle. The aceyoon's dangling Lightning cable is the weak point during hard cardio, though its in-ear seal does block gym noise better.
It depends on your ears. The RICHJOY buds weigh about 7.5 grams each and use an open design that reduces in-ear pressure, which many people find easier over hours. The aceyoon uses a traditional in-ear fit that seals the canal — more isolating, but some listeners notice pressure over time. If you dislike anything sitting deep in your ear, the open design is the safer bet.
