How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want to swim laps with music and leave your phone in the locker, choose QMHL Swimming Headphones; if you need all-day wireless earbuds that stay hooked on through sweaty runs and rain, choose Back Bay Audio Runner. These two look like competing "sports headphones," but they're built for genuinely different jobs — one is a waterproof, phone-free bone-conduction headset, the other is a wrap-around true-wireless earbud set tuned for workouts on dry land.
• QMHL's biggest strength: IP68 waterproofing rated for submersion up to 2 meters, plus a built-in 32GB MP3 player — so you can swim with music and no phone at all.
• QMHL's biggest trade-off: Bone conduction sits outside your ear canal, so it trades deep, isolating bass for open-ear safety and water resistance. It also has no charging case.
• Back Bay Audio Runner's biggest strength: A wrap-around ear-hook fit with a charged case totaling 30 hours of playtime, a bass boost mode, and touch controls.
• Back Bay Audio Runner's biggest trade-off: IPX7 protects against sweat and rain, but it is explicitly not for swimming.
• Who QMHL is for: Swimmers, surfers, and anyone who wants open-ear audio without carrying a phone.
• Who Back Bay Audio Runner is for: Runners, gym-goers, and commuters who want secure earbuds with a case and long battery life.
The QMHL Swimming Headphones solve one specific problem better than almost anything else in this comparison: how to hear music while you're actually in the water. The IP68 rating means they can be fully submerged down to 2 meters, which covers swimming, surfing, and most water sports. That's a genuinely rare capability — most "waterproof" sports earbuds are only rated for sweat and rain, not submersion.
The second standout is the built-in 32GB of memory. You load up to roughly 8,000 songs and leave your phone behind entirely. For swimmers this matters, because Bluetooth simply doesn't transmit reliably through water, and you can't exactly hold a phone at the pool. The MP3 mode is the whole point here. When you're on dry land, Bluetooth 6.0 kicks in for wireless streaming with a stated range up to 33 feet, and the battery is rated for about 9–10 hours of playtime, with a quick-charge feature that gives you roughly 2 hours from a 15-minute top-up.
The design is open-ear bone conduction with a lightweight titanium frame. Because the drivers sit against your cheekbone rather than inside your ear canal, your ears stay open to traffic, other people, and ambient sound — a real safety plus for cycling or running near roads. The package even includes noise-cancelling earplugs for times you want to block the world out instead.
Who should buy it: Swimmers, triathletes, surfers, and outdoor athletes who want phone-free audio and open-ear awareness. Who should skip it: If you want thumping bass, passive noise isolation, or a pocketable charging case, this isn't the tool for you. Anyone expecting in-ear sound quality will be disappointed by the physics of bone conduction.
The Back Bay Audio Runner is a true-wireless earbud built around staying put. The defining feature is the wrap-around ear hook — an over-the-ear design developed with input from the Boston running community specifically so the buds don't fall out mid-stride. If you've ever had a standard bud pop loose on a treadmill or a rainy 10K, that hook is the whole appeal.
The audio side leans into workout energy. A 10mm dynamic driver and a dedicated bass boost mode are tuned for punchy, motivating sound, with a stated latency of 90 milliseconds for reasonably tight audio sync. These are in-ear buds, so they deliver the passive isolation and low-end thump that bone conduction can't — which is exactly what a lot of gym and running listeners want.
Battery life is where the Runner pulls ahead on paper. Each bud plays about 6 hours, and the charging case adds another 24, for a combined 30 hours. Charge the case once and you're set for weeks of workouts. A quick 15-minute charge gives roughly 90 extra minutes of music, and the case itself recharges over USB-C in about 2 hours.
Durability is rated IPX7 — sweatproof and fine in the rain. But read the fine print: Back Bay explicitly states these are not swimming earbuds, and the fit isn't designed for it. Touch controls handle play/pause, track skipping, volume, and calls, and the earbuds work with Android and iPhone alike.
Who should buy it: Runners, gym rats, cyclists, and commuters who want secure, bass-forward earbuds with a case and long battery. Who should skip it: Swimmers — full stop. And if you specifically need open-ear awareness of your surroundings, the in-ear seal of the Runner works against you.
• Best for swimming → QMHL Swimming Headphones. Submersible to 2 meters; the Runner is explicitly not for swimming.
• Best for phone-free listening → QMHL Swimming Headphones. The 32GB built-in MP3 player holds up to ~8,000 songs with no phone needed.
• Best for battery life → Back Bay Audio Runner. A combined 30 hours (6 per bud + 24 from the case) versus roughly 9–10 hours on the QMHL.
• Best for bass and immersive sound → Back Bay Audio Runner. A 10mm dynamic driver plus a bass boost mode beats open-ear bone conduction on low-end impact.
• Best for open-ear safety → QMHL Swimming Headphones. Bone conduction keeps your ears open to traffic and surroundings.
• Best fit security on dry land → Back Bay Audio Runner. The wrap-around ear hook is purpose-built to stay in during runs.
• Best for rainy or sweaty workouts → either one. Both handle wet conditions — but only the QMHL survives being submerged.
• Best for carrying a case and recharging on the go → Back Bay Audio Runner. The QMHL has no charging case in the box.
In my opinion, the right pick comes down entirely to whether water is part of your workout. If you swim, surf, or just want music without a phone, I'd buy the QMHL Swimming Headphones — the IP68 submersion rating and 32GB player are things the Runner simply cannot do. If your sports happen on dry land, I'd buy the Back Bay Audio Runner instead: the secure ear-hook fit, bass boost, and 30-hour case battery make it the more enjoyable everyday workout earbud. Neither is "better" overall — they're built for different athletes.
Yes — the IP68 rating covers full submersion up to 2 meters, so swimming and surfing are within spec. The Back Bay Audio Runner is only IPX7 and is not intended for swimming.
No. Back Bay states clearly that these are not swimming earbuds and the fit isn't designed for it. They're fine in rain and sweat, but leave them out of the pool.
Not necessarily. They have 32GB of built-in memory for storing up to ~8,000 songs, so you can swim or run phone-free. Bluetooth 6.0 is there when you do want to stream wirelessly.
The Back Bay Audio Runner lasts longer overall, with about 6 hours per bud plus 24 hours from the charging case — around 30 hours total. The QMHL is rated for roughly 9–10 hours of continuous play.
