How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a rugged, open-ear headphone that keeps you aware of traffic on every run, choose SUNGDOGIN 2025; if you need all-day battery in a featherweight clip-on that doubles as jewelry, choose miyonsin 2026.
• SUNGDOGIN 2025 — biggest strength: bone conduction sound through the cheekbones with a titanium frame that bends without deforming, IP55 waterproofing, and up to 12 hours of playback.
• SUNGDOGIN 2025 — biggest trade-off: it's a hook-style open-ear headphone at 29 grams, so it's built for movement rather than for looking like an accessory, and it charges over Type-C rather than in a case.
• miyonsin 2026 — biggest strength: up to 48 hours of total playback with the charging case, a 4.0g-per-earbud clip-on fit, IP56 protection, and detachable sparkle butterfly earrings that make them wearable as jewelry.
• miyonsin 2026 — biggest trade-off: no noise control at all, a 10mm dynamic driver tuned for clear vocals rather than thump, and touch controls instead of physical buttons.
• Who each pick is for: SUNGDOGIN 2025 for runners, cyclists and hikers who want a durable open-ear headset with a mic; miyonsin 2026 for anyone who wants long battery, tiny clip-on comfort and a fashion-forward look.
The SUNGDOGIN 2025 is a bone conduction headphone, which means it sends sound through your cheekbones instead of firing it into your ear canal. The brand claims a fully enclosed cavity design that cuts sound leakage by up to 50%. What that buys you in the real world is simple: your ears stay completely open, so you hear the car behind you, the cyclist calling out, the dog about to cut across the path.
The build is the part I like most on paper. A titanium frame at just 29 grams, and the spec sheet says it can be stretched and bent without deforming. That matters for a headphone that's going to live in a gym bag or a jersey pocket. IP55 waterproofing covers sweat, rain and splashes, and the stated uses are running, hiking and cycling. Add Bluetooth 5.4, a built-in mic with noise cancellation for calls, and up to 12 hours of playback with Type-C charging, and you've got a headset that handles a commute, a long ride, and a work call without a pit stop.
Who should buy it: runners, cyclists, hikers and commuters who want one open-ear headphone for both training and calls, and who'd rather have a bendy titanium band than a charging case. Who should skip it: if you mainly want something discreet that looks like jewelry, or you need the multi-day battery a case provides, this isn't that product. It's a piece of sports gear, not an accessory. Earplugs are included in the box, which is a nice touch if you want to block ambient noise while still wearing an open-ear design.
The miyonsin 2026 goes after a completely different buyer. These are clip-on open-ear earbuds that rest on your ear without sealing the canal, and each one weighs just 4.0 grams. The brand calls out small ears, long hair and glasses specifically — the three situations where clip-on designs usually slip or pinch. A round ball-shaped earpiece and a 10mm dynamic driver sit inside a rose gold ABS shell, and the whole thing is styled as jewelry with detachable crystal butterfly earrings.
Battery is the headline number: up to 48 hours of total playback with the included charging case, and a 1.5-hour charge time. That's a different way of living with a headphone. You drop them back in the case and you're not thinking about a charger for days. IP56 means sweat and rain resistance, so light workouts and outdoor walks are fine. Bluetooth 6.0 is listed for fast pairing (note the spec sheet also lists 5.3 under style, so treat the 6.0 claim as the brand's headline), with a stated range of 33 feet, low latency at 60 milliseconds, and touch controls on the earbud itself.
Sound-wise, this is tuned for clear vocals and smooth balance rather than bass slam — podcast, call and playlist territory. There is no noise control of any kind, which is consistent with an open-ear design that deliberately doesn't block the world out.
Who should buy it: anyone who finds in-ear buds fatiguing, people with smaller ears or glasses who've had clip-ons slip before, and shoppers who want a headphone that reads as jewelry. It's also positioned as a gift. Who should skip it: bass chasers, and anyone who needs physical buttons or a sturdier sports frame. The ABS build and 4.0g weight trade ruggedness for lightness.
• Best for running and cycling → SUNGDOGIN 2025. Bone conduction, IP55, 29g titanium frame rated to bend without deforming.
• Best for battery life → miyonsin 2026. Up to 48 hours total with the charging case versus 12 hours on the SUNGDOGIN.
• Best for all-day wear comfort → miyonsin 2026. 4.0g per earbud, no ear-canal pressure, and the brand highlights small ears, long hair and glasses.
• Best for calls and meetings → SUNGDOGIN 2025. It's the one with a built-in mic and noise-cancelling for hands-free calls.
• Best for a fashion or gift angle → miyonsin 2026. Detachable sparkle butterfly earrings and a rose gold finish aren't features you'll find on the SUNGDOGIN.
• Best for bass and punch → neither, honestly. The miyonsin uses a 10mm dynamic driver tuned for vocals; the SUNGDOGIN is a bone conduction driver with a 20Hz–20,000Hz range. Both prioritize openness over thump.
• Best for durability in bad weather → SUNGDOGIN 2025. IP55 with a titanium frame beats an IP56 ABS clip-on when you're talking about being knocked around.
• Best for control feel → SUNGDOGIN 2025. Push buttons are easier to find mid-stride than touch panels, especially with sweaty hands.
In my opinion, the SUNGDOGIN 2025 is the more useful headphone for most people who search for "air conduction headphones" because they want one pair for sport, commuting and calls — the mic, the push buttons, the bendable titanium frame and IP55 all point that direction. The miyonsin 2026 wins a different argument: if battery life is your pain point and you want something you'll forget you're wearing, 48 hours in a case at 4.0 grams is genuinely appealing, and the jewelry angle is a real differentiator rather than a gimmick. I'd buy the SUNGDOGIN for training and the miyonsin as a second pair for everyday wear.

FAQ
Pair them over Bluetooth first — the SUNGDOGIN 2025 uses Bluetooth 5.4 and the miyonsin 2026 uses Bluetooth 6.0 — then control playback with the on-board controls: push buttons on the SUNGDOGIN, touch controls on the miyonsin. Charge the SUNGDOGIN over Type-C; the miyonsin charges its earbuds inside the included case.
Hook the band over the tops of your ears and let the transducers rest on your cheekbones for the SUNGDOGIN 2025. For clip-on designs like the miyonsin 2026, you clip each 4.0g earbud onto the outer ear so it rests gently without blocking the canal. Both styles should feel pressure-free.
I can't give you steps for Goodmans — this comparison covers the SUNGDOGIN 2025 and miyonsin 2026 only, and their pairing specs are listed above. For any open-ear headphone, the general routine is the same: turn it on, put it in pairing mode, then select it from your phone's Bluetooth list.
