If you want a do-everything headset with a boom mic and active noise cancellation for the gym, the office and long calls, choose AYI Open Ear Air; if you need a waterproof, memory-packed pair you can actually swim with and leave your phone behind, choose DOOGEEEco Bone Air Swim. Both are bone conduction headphones, but they solve very different problems — one is a headset you wear all day, the other is a pool companion. If you're deciding for switch-style workout use where you move between machines, calls and the outdoors, that single question decides it fast.
• AYI Open Ear Air — biggest strength: a rotatable boom mic with a dual-microphone system plus active noise cancellation, which makes it the more capable pick when voice clarity matters.
• AYI Open Ear Air — biggest trade-off: IPX5 only, so sweat and light rain are fine but it is not built for immersion, and there is no built-in music storage.
• DOOGEEEco Bone Air Swim — biggest strength: IP68 swimming-grade sealing and 64GB of onboard memory, so it can play music without any wireless connection at all.
• DOOGEEEco Bone Air Swim — biggest trade-off: no noise cancellation and no microphone boom, so it is a listening tool first and a calling tool second.
• Pick AYI Open Ear Air if you want one headset for calls, meetings, gym sessions and general outdoor use.
• Pick DOOGEEEco Bone Air Swim if you want music in the pool, in the rain and on long rides without carrying a phone.
The AYI Open Ear Air is built around communication as much as listening. It uses open-ear air conduction so your ear canals stay unblocked, which means you keep your situational awareness while you train or work. On top of that it adds a rotatable boom mic and a dual-microphone system, so the microphone can be swung into position near your mouth instead of sitting somewhere vague on the frame. In my opinion that is the single most useful design decision on this model — it is the difference between a headset you tolerate on calls and one you reach for.
The second thing that stands out is active noise cancellation, controlled by push buttons. ANC in an open-ear design is unusual, and it tells you the target buyer is someone who takes calls in noisy places — a shared gym floor, a busy street, a home office with background chatter. Bluetooth 5.4 handles pairing and connection stability, and the rated battery life is 10 hours, which covers a long work day or several workouts between charges. It is also rated IPX5, so sweat and light rain are not a problem.
Who should buy it: anyone who wants one headset that flips between music and voice. If you spend part of your day on calls and part of it running or lifting, the boom mic and ANC are the features you will actually feel. The 20 Hz – 20,000 Hz frequency range and 140-ohm impedance describe a standard full-range driver, and the over-ear open-ear fit is designed for long sessions without pressure in the ear canal.
Who should skip it: swimmers. IPX5 does not cover immersion, and there is no local storage, so you always need a connected device nearby. If your main sport is in the water, this is not the model for you.
The DOOGEEEco Bone Air Swim is designed around one hard constraint: water blocks wireless signals. The answer here is dual-mode operation. In wireless mode it is a normal Bluetooth 5.4 open-ear headphone with a 10-metre range. In MP3 mode it plays from 64GB of built-in memory — enough for a claimed 16,000 tracks — with no connection needed at all. That is the feature that makes it a genuine swimming headphone rather than a waterproof one you're afraid to get wet.
The sealing backs this up. IP68 is rated for 2 metres of immersion for up to 2 hours, which covers pool training and casual diving, and it also handles rain running and heavy sweat. Battery is a 140mAh cell with up to 8 hours of playback in wireless mode at 75% volume and about 5 hours in MP3 mode at full volume, plus a 10-minute quick charge that gives roughly 2 hours of music. The frame is a lightweight 26.5g combination of silicone ear hooks and a titanium memory steel wire, with an adjustable strap that fits smaller heads, including women and kids.
Audio is where this model takes its own path. It uses dual bone and air conduction drivers — bone conduction for the highs and mids, air conduction for bass. That is a different approach from a pure bone conduction driver, and it is the reason the brand positions it as an open-ear headphone with real low end. It also ships as a complete kit: magnetic charging cable, silicone and sponge swimming earplugs, anti-slip elastic strap, hard carry case, manual and service card.
Who should buy it: swimmers first, but also cyclists, runners and gym-goers who want music without a phone and want the reassurance of a hard case. Who should skip it: anyone who needs to take calls. There is no noise control and no microphone boom listed, so treat it as a music device.
• Best for calls and meetings → AYI Open Ear Air. The rotatable boom mic and dual-mic system are the deciding features.
• Best for hearing your surroundings with less ambient noise → AYI Open Ear Air. It is the only one of the two with active noise cancellation.
• Best for swimming → DOOGEEEco Bone Air Swim. IP68 with 2m/2h immersion and MP3 mode is a different category of waterproofing.
• Best for leaving your phone behind → DOOGEEEco Bone Air Swim. 64GB of onboard storage does the job.
• Best for battery life on paper → AYI Open Ear Air. 10 hours rated versus up to 8 hours wireless on the DOOGEEEco.
• Best for a quick top-up charge → DOOGEEEco Bone Air Swim. A 10-minute charge returns about 2 hours of playback.
• Best for a lighter, more adjustable fit → DOOGEEEco Bone Air Swim. A 26.5g frame with silicone hooks, titanium memory wire and an adjustable strap.
• Best for a full accessory kit out of the box → DOOGEEEco Bone Air Swim. Earplugs, strap, case and cable are included.
• Best all-rounder for mixed work and training → AYI Open Ear Air. It covers voice and music in one device.
If I had to buy one, I would buy the AYI Open Ear Air, because most people's week is dominated by calls, commutes and mixed workouts rather than pool sessions, and the boom mic plus ANC is the harder combination to replace. The for switch-style use case — moving between a desk, a gym floor and the outdoors — is exactly where that headset design pays off. If you swim, though, my recommendation flips without hesitation: buy the DOOGEEEco Bone Air Swim, because IP68 and 64GB of local music solve a problem the AYI simply cannot.
