If you want one pair of headphones that keeps your ears open to traffic and lasts through a long run, choose MZYQCY Bone Conduction Headphones; if you need to block out light and drift off to audio in bed, choose Yeguwithu Sleep Mask. These two products solve completely different problems, and the wrong pick will frustrate you fast.
• MZYQCY Bone Conduction Headphones — biggest strength: an open-ear bone conduction design that leaves your ear canals free so you can hear traffic, other runners and emergency signals while you train.
• MZYQCY Bone Conduction Headphones — biggest trade-off: open-ear audio means you are not getting isolation, so loud environments will compete with your music, and the fit depends on the headband sitting correctly on your cheekbones.
• Yeguwithu Sleep Mask — biggest strength: a 3D contoured blackout mask with built-in repositionable speakers, so you can listen to white noise, podcasts or meditation tracks while blocking light.
• Yeguwithu Sleep Mask — biggest trade-off: it is a sleep and rest product, not workout gear — you would not run or cycle in it, and the electronics have to be removed before washing.
• Who each pick is for: MZYQCY is for runners, cyclists and outdoor athletes who want awareness plus a long battery; Yeguwithu is for sleepers, travelers, side sleepers and night-shift workers who want audio and darkness at the same time.
The MZYQCY set is built around one idea: keep your ears open. Instead of pushing sound into your ear canal, it rests on your cheekbones and transmits audio that way, which is why the ear placement is listed as open ear. For anyone who runs on roads, shares a path with cyclists, or just does not like the sealed-in feeling of earbuds, that is the whole point. You hear the world around you while your music keeps playing.
The spec sheet backs up the outdoor angle. You get 15 hours of playback on a single charge, with a charge time of about 1.5 hours and a magnetic charging cable in the box. Bluetooth 5.4 handles the connection, and the stated range is roughly 49 feet, so you can leave your phone on a bench or in a bag and keep moving. At 29 grams it is genuinely light, and the titanium frame is described as staying put during sprints or yoga. An IPX6 rating covers sweat and heavy rain, which matters if you train outside year-round. There are also stereo mics with noise reduction for calls, plus push-button controls for play, pause, skipping and answering.
Who should buy it: runners, cyclists, hikers, gym-goers and commuters who want situational awareness, a long battery and a sweat-resistant build. In my opinion it is also a good fit for anyone who finds regular earbuds uncomfortable over long sessions. Who should skip it: if you want deep isolation on a noisy plane or in a loud office, bone conduction is the wrong tool — you will hear everything around you. And if you are shopping specifically for sleep, this is not a sleep product; it is a sports headphone.
The Yeguwithu mask takes the opposite approach. It is a 3D contoured sleep mask first, with a Bluetooth audio system built in. The contoured structure creates extra space around your eyes rather than pressing flat against them, and the job is to block unwanted light. Inside, there are wireless speakers you can reposition so they line up with your ears — that adjustability is the detail that makes it workable for side sleepers, who otherwise end up with a speaker digging into their head.
The comfort story is thought through. The fabric is soft polyester with memory foam cushioning, and the headband is adjustable for head circumferences from 21 to 29 inches. The hook-and-loop closure is designed to reduce hair pulling when you tighten or loosen it, which is a small thing that matters a lot if you wear your hair long. Battery life is listed at 10 to 12 hours of continuous playback, enough to cover a full night without a mid-sleep charge. Bluetooth 5.4 gives you quick pairing and a range of roughly 10 to 15 meters to a phone or tablet.
One practical detail stands out: the Bluetooth module and speakers are removable, so you can wash the mask and refresh it regularly. That is the difference between a product you keep using and one that gets gross in a month. Who should buy it: side sleepers, frequent flyers, meditators, yoga practitioners, night-shift workers and anyone who falls asleep to podcasts or white noise. Who should skip it: if you need headphones for running or cycling, this is not that — it is not rated for sweat or water, and wearing a mask while moving outdoors is a bad idea.
Side-by-Side: Which Should You Choose?
• Best for workouts and outdoor training → MZYQCY Bone Conduction Headphones. Open-ear design, IPX6 sweat and rain resistance, and a 29g frame built for movement.
• Best for sleep and blocking light → Yeguwithu Sleep Mask. The 3D contoured blackout structure is the entire reason it exists.
• Best for side sleepers → Yeguwithu Sleep Mask. Repositionable speakers and memory foam cushioning are designed around lying on your side.
• Best for long battery sessions → MZYQCY Bone Conduction Headphones. 15 hours versus the 10–12 hours listed for the mask.
• Best for listening in bed without disturbing a partner → Yeguwithu Sleep Mask. Speakers sit against your ears inside the mask, and there is no open-ear leakage into the room.
• Best for hygiene over time → Yeguwithu Sleep Mask. The electronics come out and the mask can be washed.
• Best for calls on the go → MZYQCY Bone Conduction Headphones. Built-in mics with noise reduction and push-button call controls.
• Best for travel where you want darkness → Yeguwithu Sleep Mask. It covers flights and naps, not just bedtime at home.
In my opinion, these two are not really competitors — they are answers to two different questions, and the right buy depends on which question you are asking. If I were shopping for training, commuting or any kind of outdoor movement, I would buy the MZYQCY Bone Conduction Headphones: the open-ear design, IPX6 rating, 15-hour battery and 29g weight line up exactly with what an active user needs. If my goal were falling asleep to audio, the Yeguwithu Sleep Mask would win without hesitation, because a sports headphone cannot block light and a sleep mask cannot survive a sweaty run. Buy for the job you actually have.
No — they are designed for sports and outdoor use, not sleep. They do not block light, they are not built for lying on a pillow, and their open-ear design is meant for awareness during activity rather than overnight rest.
It is not designed for that. There is no water or sweat resistance listed, and a blackout mask over your eyes is a poor fit for outdoor movement. Its listed uses are travel, meditation, naps, night shifts and resting at home.
MZYQCY is listed at 15 hours of playback with roughly a 1.5-hour charge time. Yeguwithu is listed at 10 to 12 hours of continuous playback. For a full night of sleep audio, the mask's range is plenty; for long training blocks, the headphones go further.
That depends on what you need it to do, not on the spec sheet alone. A sleep mask is the better value if you want darkness plus audio in bed, and the headphones are the better value if you want open-ear sound for exercise. Check the current price on Amazon for each before deciding, since that is the part I cannot judge for you.
