If you want an open-ear earbud with a proper charging case, big bass drivers and a long battery reserve, choose DUVOSS Open Ear Earbuds; if you need true bone conduction with a featherlight titanium frame and dual-device pairing, choose AYI True Bone Conduction.
Both sit in the same "keep your ears open" category, but they solve the problem in two different ways. The DUVOSS pair is an air-conduction design with ear hooks and a case that carries extra charge. The AYI headset transmits sound through your cheekbones with a band-style frame that weighs next to nothing. Which one is right for you comes down to how you wear them and what you want to hear.
• DUVOSS biggest strength: a 16.2mm hybrid driver with Liso2.0 bass enhancement, plus up to 10 hours per charge and a 500mAh case that adds a huge standby reserve — in my opinion the better pick if you want fuller sound and a case you can toss in a bag.
• DUVOSS biggest trade-off: it's a bulkier setup. The buds sit on ear hooks, and the case itself measures roughly 4.3 x 1.77 x 3.66 inches and weighs 3.52 ounces, so it's not something you forget you're carrying.
• AYI biggest strength: genuine bone conduction through the cheekbones in a titanium frame that weighs under 25 grams — the more "barely there" option, with 11 hours of playtime and dual pairing across two devices.
• AYI biggest trade-off: no charging case and no carry weight to hide behind. You get one battery, and bone conduction sound is thinner by nature than a large air-conduction driver.
• Who DUVOSS is for: gym-goers, commuters and shoppers who want music with real low-end and don't mind a case.
• Who AYI is for: runners, cyclists and drivers who want maximum awareness and minimum weight on their head.
The DUVOSS Open Ear Earbuds are built around comfort and sound output. The structure is open-ear with flexible silicone cushions and soft adjustable ear hooks, which is the design that keeps pressure off the ear canal during long wear. If you've ever pulled regular buds out after an hour because your ears ached, this is the shape that fixes that. The trade is that the hooks are visible and the fit is more "worn" than "forgotten".
Battery is where DUVOSS pulls clearly ahead on paper. Up to 10 hours of continuous playback per charge from the 100mAh buds, plus a 500mAh carrying case with 50 hours of standby. Charging is over USB-C, and the case takes about 6 hours to top up. The IPX4 rating, double-layer steel-gauze mesh and sealed construction cover sweat and light rain — fine for the gym or a drizzly run, not for swimming.
Buy it if you want the fuller-sounding, longer-reserve option and you're happy to carry a small case. Skip it if every gram matters to you, or if you specifically want bone conduction rather than air conduction. It ships in white with a USB-to-USB-C cable and a manual.
AYI True Bone Conduction: Who It's For
The AYI True Bone Conduction headset does the opposite trick: it removes the earbud entirely. Sound travels through your cheekbones, so nothing enters or covers your ear canal at all. The frame is titanium and flexible, and the whole thing weighs under 25 grams. That combination — no ear intrusion plus almost no weight — is the reason people reach for bone conduction in the first place. It stays put without bouncing or slipping, which is exactly what you want while running, cycling or skiing.
Battery is a straightforward 11 hours of continuous playtime on a single charge, with no case in the picture. That's longer than the DUVOSS buds alone manage per charge, but DUVOSS claws all of that back and then some with its case. The AYI's Bluetooth 5.3 chip supports dual pairing, so you can stay connected to your phone and your laptop and switch between them without re-pairing — genuinely useful if you take calls at a desk and then head out.
Durability is stated as IPX7 waterproof and sweatproof in the feature list, which would make it the more weather-tolerant of the two against heavy sweat and rain. One thing worth flagging honestly: the spec sheet lists IPX4 in the same section, so if maximum water resistance is your deciding factor, treat the rating as something to verify rather than assume. On sound, AYI claims upgraded bone conduction drivers with rich stereo and noise-canceling microphones for calls. Bone conduction is inherently lighter on bass than a 16.2mm air driver — that's physics, not a defect.
Buy it if you prioritize total awareness, minimal weight and dual-device switching. Skip it if you want deep low-end, or you like the idea of a case that keeps charging your buds between sessions.
• Best for bass and fuller sound → DUVOSS Open Ear Earbuds. A 16.2mm hybrid driver with dedicated bass enhancement beats what a bone conduction driver can move.
• Best for all-day battery reserve → DUVOSS Open Ear Earbuds. 10 hours per charge plus a 500mAh case and 50 hours of standby is the bigger total picture.
• Best for maximum situational awareness → AYI True Bone Conduction. Nothing sits in or over your ear canal, so traffic and surroundings come through unobstructed.
• Best for lightest possible wear → AYI True Bone Conduction. Under 25 grams in a flexible titanium frame versus a hook-and-case system you have to carry.
• Best for two-device workflows → AYI True Bone Conduction. Dual pairing lets you hop between phone and laptop without reconnecting.
• Best for gym and light rain → DUVOSS Open Ear Earbuds. IPX4 with sealed mesh handles sweat and drizzle; just don't expect swim-proofing.
• Best for cycling, running and skiing → AYI True Bone Conduction. The no-bounce, no-slip frame and open-ear safety design fit high-motion sports.
• Best for a case you can lose in a bag → DUVOSS Open Ear Earbuds. The carrying case is the whole charging story, and it's compact enough to live in a pocket or pack.
My Verdict
Neither is universally better. DUVOSS wins on driver size, battery reserve and case convenience; AYI wins on weight, open-ear awareness and dual-device pairing. Match it to how you'll wear them.
No. The spec sheet lists only an 11-hour battery with no carrying case, while DUVOSS ships a 500mAh case for extra standby charge. If a case matters to you, that's a real difference.
Both are designed for it. DUVOSS uses IPX4 sealing against sweat and light rain; AYI uses a sub-25g titanium frame that resists bouncing. For heavy weather, verify the AYI's water rating, since the sheet lists both IPX4 and IPX7.
Yes — both list noise-canceling microphones. DUVOSS adds DT3.0 directional sound transmission and dual-mic noise cancellation; AYI relies on its built-in noise-canceling mic for clear voice pickup outdoors.
