How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want an open-ear headphone that keeps you aware of traffic and the world around you on every run, choose MZYQCY Bone Conduction Headphones; if you need earbuds that seal in bass, block out noisy rooms and last across a long trip, choose PEFUPEW Earbuds.
• MZYQCY's biggest strength: a true open-ear, bone-conduction fit at 29g with a 15-hour battery and Bluetooth 5.4 rated out to roughly 50 feet — awareness and endurance in one package.
• MZYQCY's biggest trade-off: open-ear sound means you never fully block the outside world, and it's a single 15-hour charge with no charging case to top it up on the go.
• PEFUPEW's biggest strength: a sealed in-ear design with 14.2mm dynamic drivers, ENC call noise reduction and a charging case that stretches total playtime to about 40 hours, all shown on a dual LED display.
• PEFUPEW's biggest trade-off: the in-ear seal that gives you that bass and isolation is exactly what cuts you off from traffic and surroundings — and the buds themselves only run about 8 hours per charge.
• Choose MZYQCY if your priority is hearing the road, the trail or your running buddies while you train outdoors.
• Choose PEFUPEW if your priority is immersive sound, clear calls in loud places and maximum total battery between charges.
The MZYQCY set is built around one idea: keep your ear canals open. It rests on your cheekbones and transmits sound that way, so traffic, cyclists, and emergency signals stay audible while your music plays. For anyone who runs, cycles or walks near roads, that's not a gimmick — it's the whole reason to pick this style over sealed earbuds.
The endurance story backs it up. MZYQCY rates 15 hours of playback on a single charge, with a 1.5-hour charge time, and the connection runs on Bluetooth 5.4 with a stated range of up to about 50 feet. Multipoint lets you hop between devices — phone to watch to gym equipment — without re-pairing each time. At 29g with a titanium frame, it's meant to sit still through sprints and yoga rather than bounce around. Controls are push-button, which I actually prefer for sweaty outdoor sessions because physical buttons don't misread a wet tap the way touch sensors sometimes do.
The IPX6 rating covers heavy sweat, rain and splashes. There's environmental noise cancellation and built-in mics with noise reduction for calls, though on an open-ear design you should expect call clarity to lean on the mic array rather than on any seal around your ear.
PEFUPEW Earbuds: Who It's For
PEFUPEW goes the opposite direction. These are in-ear buds with soft silicone tips that press into the ear canal, and each bud weighs about 3 grams. That seal is the point: it gives you the low-end punch from the 14.2mm dynamic drivers and it's what makes the sound feel full rather than ambient.
Battery is where PEFUPEW plays its strongest card. Each bud runs about 8 hours, and the 400mAh charging case extends total playtime to roughly 40 hours, with a 1.5-hour fast charge. The dual LED display shows the case and bud battery as a percentage, so you know exactly where you stand instead of guessing from a blinking dot. For a long flight, a workday plus an evening gym session, or a weekend trip where you don't want to think about charging, that's a real advantage.
Calls get attention too. The ENC noise reduction is aimed at filtering background noise so your voice comes through in busy places — commuting, a coffee shop, a shared office. Bluetooth 5.4 handles the connection, with magnetic Hall-effect pairing that reconnects the moment you lift the buds out of the case. Controls are touch-based, and the IP7 nano-coating shrugs off sweat and rain.
Who should buy it: commuters, office workers, travelers and gym-goers who want immersive sound, clear calls and long total battery. Who should skip it: if you run or ride near traffic and need to hear what's coming, the in-ear seal works against you — and at 8 hours per charge, the buds alone fall well short of MZYQCY's single-charge runtime.
• Best for situational awareness → MZYQCY Bone Conduction Headphones. Open-ear design keeps traffic and surroundings audible; the PEFUPEW seal does the opposite.
• Best for total battery life → PEFUPEW Earbuds. About 40 hours with the case beats a single 15-hour charge, and the LED display removes the guesswork.
• Best for outdoor sport in rain and sweat → MZYQCY. IPX6 and a 29g frame built to stay put through sprints.
• Best for immersive bass and sealed sound → PEFUPEW. 14.2mm dynamic drivers in an in-ear fit.
• Best for calls in noisy places → PEFUPEW. ENC noise reduction is aimed squarely at filtering background noise on calls.
• Best for wireless range and multipoint → MZYQCY. Bluetooth 5.4 with a stated range up to about 50 feet and easy device switching.
• Best for touch-free, glanceable battery checks → PEFUPEW. Dual LED percentage readout on the case.
• Best for commuters who split time between desk and street → PEFUPEW for the desk, MZYQCY for the street. If you can only own one, decide which half of your day matters more.
In my opinion, the right pick hinges entirely on whether you want to hear the world or shut it out. If your listening happens on roads, trails and sidewalks — running, cycling, walking — I'd buy the MZYQCY Bone Conduction Headphones. The open-ear fit, IPX6 rating and 15-hour single charge are exactly what outdoor training demands, and the awareness factor is something sealed buds simply can't match. If instead your listening happens on planes, in offices and at the gym, I'd buy the PEFUPEW Earbuds: the sealed in-ear sound, ENC call clarity and roughly 40 hours of total playtime make them the better everyday companion. Decide which of those two lives is more yours, and the choice makes itself.
For running near traffic, yes — in my opinion. MZYQCY's open-ear design leaves your ear canals open so you hear cars and other people, and its IPX6 rating handles sweat and rain. PEFUPEW's in-ear seal blocks that awareness, which is great at a desk and less ideal on a road.
PEFUPEW wins on total playtime. Its buds run about 8 hours per charge and the 400mAh case extends that to roughly 40 hours, while MZYQCY delivers 15 hours on a single charge with no case. MZYQCY wins if you want one long session without carrying anything extra.
They use ENC noise reduction aimed at filtering background noise so callers hear you more clearly in busy places. Note that ENC mainly targets your voice pickup on calls — it isn't the same as active noise cancellation for your music.
You can't fully have both here. MZYQCY gives awareness but an open, ambient sound; PEFUPEW gives sealed bass but cuts you off from surroundings. Pick based on where you listen most, and check the current price on Amazon before deciding.
