How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want an everyday open-ear pair with huge battery life, adjustable hooks, app EQ and built-in AI translation, choose 1Mii E35; if you need a bone conduction headset you can actually swim with, with 32GB of onboard storage and IPX8 waterproofing, choose SONR Bone Conduction Waterproof.
• 1Mii E35 biggest strength: open-ear awareness plus up to 45 hours of total playtime (18 hours per charge), a 16.2mm dynamic driver, 4-mic calls, and app-level EQ and control customization.
• 1Mii E35 biggest trade-off: it is a land-and-commute design — the sheets describe it as sweat-proof, not swim-proof, and there is no onboard music storage, so it always needs a paired device.
• SONR Bone Conduction Waterproof biggest strength: bone conduction sound through the cheekbones, IPX8 waterproofing for swimming and triathlon, and 32GB of storage (29GB usable) so you can listen with no phone at all.
• SONR Bone Conduction Waterproof biggest trade-off: shorter battery at up to 8 hours per charge, button-only controls, and no app EQ — it is built for training, not for all-day desk work.
• Who each is for: pick the 1Mii E35 for workdays, commutes, calls and long listening sessions; pick the SONR for pool sessions, open-water swims and multisport training where a phone can't come along.
The 1Mii E35 is an open-ear earbud built around the idea that you should never have to choose between your audio and your surroundings. The hook-style earpieces sit outside the ear canal, so ambient sound — traffic, a coworker, a coach's whistle — stays audible. That is the core of aware-mode listening, and it is baked into the physical design rather than being a software toggle you have to remember to switch on.
Where it pulls ahead of most open-ear rivals is endurance and flexibility. The sheets list up to 18 hours of listening on a single charge and up to 45 hours total with the case, plus a 1.5-hour charge time. For someone who wears earbuds through a full workday and then straight into an evening run, that means charging roughly once a week rather than every night. The adjustable ear hooks rotate up to 60° across multiple angles, which matters more than it sounds: open-ear fit is fussy, and being able to angle the hook is the difference between "secure" and "annoying."
Sound comes from a 16.2mm dynamic driver with a 20Hz–20kHz range, and 1Mii says the acoustic tuning is aimed at reducing the sound leakage that open designs normally suffer from. Four microphones with environmental noise cancellation handle calls, which is the practical reason to care: open-ear buds are usually the worst option for phone calls, and this is 1Mii's answer to that. Controls are unusually generous — touch, physical buttons, and app support for EQ and function remapping. There's also an AI layer for voice chat, English practice, contextual learning and real-time translation across 103 languages, which is a genuinely unusual feature at this tier and points at students and frequent travelers.
Buy it if you want one pair for commutes, the office, calls and workouts, you value long battery life, and you like tuning your own sound. Skip it if you swim — this is a sweat-proof open-ear design, not a waterproof one, and there's no built-in storage, so a phone or watch has to come with you.
The SONR Bone Conduction Waterproof is a different animal entirely. It uses bone conduction drivers that transmit sound through your cheekbones, leaving your ear canals completely open. In practice that means two things: you keep full situational awareness of traffic, other swimmers or a training partner, and your ears stay dry and unpressurized, which is a real comfort win over in-ear buds during long sessions.
The headline feature is the combination of IPX8 waterproofing and 32GB of onboard storage, 29GB of which is usable. That is the whole point. In Bluetooth mode you stream from your phone on dry land; in MP3 mode you load tracks over USB and swim with no phone, no signal, and no waterproof pouch. If you've ever tried to take music into a pool, you know how rare that combination is. The built-in microphone handles calls during dry-land workouts, though the sheets are specific that this is for dry land — not underwater.
Battery is rated at up to 8 hours of continuous playtime per charge. For a swim set or a triathlon block, that's plenty; for a full workday of back-to-back meetings, it isn't. The wrap-around frame is described as lightweight and ergonomic, designed to stay put through heavy swim sets and fast runs, and the controls are button-only — no touch surface, no companion app, no EQ customization. The model carries a 1-year warranty.
Buy it if you swim, you're training for a triathlon, or you want music in the water without carrying a phone. Skip it if you need all-day battery, app-based tuning, or you want to wear the same pair from morning meetings through evening without recharging.
Side-by-Side: Which Should You Choose?
• Best for battery life → 1Mii E35. Up to 18 hours per charge and up to 45 hours with the case, versus up to 8 hours on the SONR.
• Best for phone calls → 1Mii E35. Four microphones with environmental noise cancellation versus a single built-in mic rated for dry-land use.
• Best for sound customization → 1Mii E35. App support for EQ and control remapping; the SONR is button-only with no app.
• Best for phone-free listening → SONR Bone Conduction Waterproof. MP3 mode means you can leave the phone behind entirely; the 1Mii E35 always needs a paired device.
• Best for all-day comfort and fit tuning → 1Mii E35. Ear hooks with up to 60° of multi-angle adjustment for different ear shapes.
• Best for unusual extras → 1Mii E35. Real-time translation across 103 languages and AI voice chat are not features you'll find on most open-ear buds.
• Best for a single-purpose training tool → SONR Bone Conduction Waterproof. It does one job — sport, especially in water — and does it without compromise.
In my opinion, most people asking this question should buy the 1Mii E35. It covers more of real life: long battery, four-mic calls, adjustable hooks, app EQ, and an awareness-first open-ear design that works in traffic, at a desk, and on a run. I'd only point you to the SONR Bone Conduction Waterproof if swimming or triathlon is the actual reason you're shopping — because if it is, nothing about the 1Mii E35 solves your problem, and the SONR's IPX8 rating and 32GB of storage solve it completely. Buy for the water, or buy for the day. Not both.
Ambient aware mode is a feature that pipes outside sound into your ears so you can hear your surroundings while audio plays. On the 1Mii E35 this is achieved physically through its open-ear hook design, which leaves the ear canal unobstructed rather than relying on a software transparency setting.
On Bose models, aware mode is toggled through the Bose app or by cycling the noise-control button on the earcup. Note that neither product on this page works that way — the 1Mii E35 is open-ear by design and the SONR uses bone conduction, so both keep your ears open without any mode to switch on.
JLab's ambient aware is usually controlled via the JLab app or a button press sequence on the earbud. Again, that's a software feature on sealed earbuds; the 1Mii E35 and SONR Bone Conduction Waterproof don't have a sealed mode to toggle out of, because awareness is inherent to their open-ear builds.
On Bose, you'd cycle back to quiet mode using the noise-control button or the app. If what you actually want is the ability to block the world out, neither of these two is the right pick — both are designed to keep you aware, and the SONR's IPX8 waterproofing and 32GB storage are aimed at swimmers, not at noise cancellation.
