• APOYOU 2 biggest strength: A true 2-in-1 design — a 1.43" AMOLED smartwatch with a 300mAh battery plus a pair of 2.6g earbuds. It tracks heart rate, sleep, steps, calories, distance and blood oxygen, and covers 100+ sport modes.
• APOYOU 2 biggest trade-off: It's a watch first. The earbuds live in/with the watch body, so you're committing to a 49mm, 14mm-thick wearable on your wrist, and it's rated simply "water resistant" with no GPS.
• Emzwin Glasses biggest strength: Audio where your ears actually want it — open-ear speakers, a microphone, polarized UV-protection lenses, Bluetooth 5.3 and up to 10 hours of continuous listening per charge at just 35g.
• Emzwin Glasses biggest trade-off: No screen, no fitness tracking, and the spec sheet lists it as "not water resistant" (with a separate IPX4 sweat/splash note) — it's an audio-and-vision accessory, not a health device.
• Who each pick is for: APOYOU 2 for the workout-and-health-tracking crowd; Emzwin Glasses for commuters, drivers and anyone who wants music and calls without blocking their ears.
The APOYOU 2 is a fitness wearable that happens to have a clever party trick: the earbuds. The watch side gives you a 1.43-inch AMOLED full-touch display at 466 pixels of resolution, which in plain terms means a small screen that still shows vivid, saturated color rather than a washed-out LCD panel. On the health side it's genuinely busy — 24-hour continuous heart rate monitoring, sleep duration and sleep-depth data, blood oxygen, step counting, calories burned and distance, plus sedentary reminders and a smart alarm. If you like the idea of glancing at your wrist and knowing how your day and your night went, this is the whole point of the watch.
Then there's the training side. APOYOU lists 100+ sport modes — walking, climbing, running, swimming, basketball, badminton, pingpong and more — and the watch is described as water resistant, so pool and shower splashes are part of the intended use. The 300mAh battery with a low-power design supports long standby, and a full charge takes about three hours. The earbuds themselves weigh just 2.6g each, which is light enough that they're meant to disappear in your ear, and they use AI noise reduction to clean up calls and music. The watch case is 49mm across and 14mm thick on a 22mm strap, so it wears like a proper sports watch rather than a dainty one.
Who should buy it: anyone who wants one device for steps, sleep, heart rate and music, and doesn't want to carry a separate earbud case. Runners, gym-goers, walkers and people who take calls while driving or working are squarely in the target zone, and it works with Android 8.0 and iOS 12.0 or above. Who should skip it: if you want a big-screen experience, GPS route tracking, or you dislike wearing something substantial on your wrist, this isn't the shape you're after — GPS geotagging is explicitly not included, and the pink metal-band styling won't suit everyone.
The Emzwin Glasses flip the whole idea. Instead of putting a screen and a sensor suite on you, they put two tiny open-ear speakers and a microphone into a flexible plastic frame and let you keep your eyes and ears on the world. The lens is polarized and offers UV protection, so it's doing real sunglasses duty while it plays audio. Because the speakers sit outside your ear canal rather than in it, you stay aware of traffic, conversations and your surroundings — which is exactly why this category appeals to cyclists, drivers and people working in open offices or warehouses.
The control story is simple. There's a multifunction button: hold it about 1.5 seconds to wake your phone's voice assistant and then just talk — Siri, Google Now or Cortana, depending on your phone. Once paired, you can take calls, listen to music, adjust volume and skip tracks from the frame itself. Pairing is a two-step routine: with the glasses off, hold the power button about three seconds until the red and green lights alternate, then pick "Vision 6A" from your phone's Bluetooth list and confirm. Emzwin also gives you a volume tip worth remembering — after pairing, raise your phone's volume first, then use the glasses' volume+ button, otherwise you'll wonder why it sounds quiet.
Battery is the standout number here: up to 10 hours of continuous listening per full charge from a 180mAh cell, with a Bluetooth range of about 30 feet on Bluetooth 5.3. The whole thing weighs 35 grams including the lens, which is light for glasses you'd wear for hours. Charging is over USB-C. The frame is flexible plastic, the shape rectangular, and the intended audience is unisex adults and youth 12 and up.
Who should buy it: commuters, drivers, runners who want music without sealed ears, and anyone who already wears sunglasses and wants fewer gadgets. Who should skip it: if you want step counts, heart rate or sleep data, this device simply doesn't do that — there's no screen and no fitness tracking. And note the discrepancy in the specs: the water resistance field says "not water resistant" while the feature copy mentions IPX4 sweat and splash resistance, so treat heavy rain and swimming as off-limits and don't push your luck.
• Best for health and fitness tracking → APOYOU 2. Heart rate, sleep, blood oxygen, steps, calories and 100+ sport modes.
• Best for all-day audio comfort → Emzwin Glasses. 35g total, open-ear design, up to 10 hours per charge.
• Best for wearing in bright sun → Emzwin Glasses. Polarized lenses with UV protection; APOYOU 2 is a watch, not eyewear.
• Best for screen quality on your wrist → APOYOU 2. A 1.43" AMOLED touch display at 466 resolution versus no display at all.
• Best for situational awareness while listening → Emzwin Glasses. Nothing blocks your ear canal.
• Best for one-device convenience → APOYOU 2. Watch and earbuds together, with call reminders, notifications from Facebook, WhatsApp, Instagram and SMS, find-my-phone, remote camera and customizable dials.
• Best for voice-assistant control → Emzwin Glasses. One long press wakes your assistant for calls, weather and traffic.
• Best for water exposure → APOYOU 2. Listed as water resistant and designed around swimming among its sport modes; the glasses are the more delicate of the two.
If I had to pick one, I'd buy the APOYOU 2. In my opinion it's the more useful object day to day: it tracks the things most people actually want tracked, gives you a bright AMOLED screen at a glance, and bundles the earbuds so there's one less case in your bag. The Emzwin Glasses are the smarter buy only if audio and sunglasses are your priority and health data means nothing to you — they're lighter, they last longer per charge, and the open-ear design is genuinely better for commuting and driving. But as a single do-everything wearable, the APOYOU 2 covers more ground.
FAQ
It's both in one package — a 1.43" AMOLED smartwatch with a 300mAh battery plus 2.6g earbuds, so you get fitness tracking and audio from a single device.
No. The listed applications are music, phone calls, voice assistant and sports audio only. If you want step counts, sleep data or heart rate, you need a tracker like the APOYOU 2.
Emzwin states up to 10 hours of continuous listening, which is a straightforward audio runtime. APOYOU 2 emphasizes long standby from its larger 300mAh battery but doesn't publish an equivalent music-hours figure, so a direct number-for-number comparison isn't possible.
APOYOU 2 is listed as water resistant and includes swimming among its sport modes, so it's the more forgiving option. The Emzwin specs say "not water resistant" while also mentioning IPX4 sweat and splash resistance — so keep them out of heavy rain and water.
