• Langsdom Running Headphones AirWave — biggest strength: Open-ear design plus a built-in 32GB memory mode, so you can load songs onto the headphones themselves and leave your phone at home.
• Langsdom Running Headphones AirWave — biggest trade-off: No charging case and no noise isolation, so you hear everything around you and you'll need to remember that magnetic charging cable.
• Back Bay Audio Runner — biggest strength: A 30-hour total battery setup (6 hours per bud plus a 24-hour charging case), USB-C charging, and a bass boost mode for people who want their music to hit.
• Back Bay Audio Runner — biggest trade-off: They're in-ear with sound isolation, so you're closed off from traffic and your surroundings, and the case adds bulk to your pocket.
• Who each pick is for: Langsdom Running Headphones AirWave for the outdoor runner, cyclist or commuter who wants awareness and phone-free playback; Back Bay Audio Runner for the gym-goer or treadmill runner who wants immersive, bass-heavy sound and a case that keeps the buds charged for weeks.
The AirWave Pro is built around one idea: keep your ears open. It's an open-ear model with a memory titanium alloy frame wrapped in skin-friendly silicone, and it weighs just 26 grams — light enough that the wrap-around design is meant to feel like almost nothing is there. The rounded-tip earpieces sit outside the canal rather than inside it, which is exactly why you can still hear a car coming up behind you on a road run. For anyone who has ever felt genuinely nervous running with sealed earbuds in, that's the whole point.
The feature that separates it from almost everything else in this category is the built-in 32GB of memory. You can drag MP3 files straight onto the headphones using the magnetic charging cable as a data cable, or use the included USB-C OTG adapter to pull music from a device. No phone required on the run. You also get physical push buttons rather than touch controls, which I'd argue is the right call when your hands are sweaty.
Who should skip it? If you want your music to block out the gym, this isn't it. There's no noise control at all, and the open design means ambient sound is a feature, not a bug. If you want a charging case to top the buds up, you won't find one here.
Back Bay Audio Runner: Who It's For
The Back Bay Audio Runner 40 takes the traditional route and does it well. These are in-ear buds with an ear hook that wraps over the top of your ear — Back Bay says the shape was developed with input from the Boston running community, and the goal is simple: buds that don't pop out mid-stride. Each bud weighs very little on its own, the total listed weight of 45 grams covers the set, and the hook-over design is aimed at people who've had standard earbuds work loose on them.
Sound is where this pair leans hard. There's a dedicated bass boost mode, 10mm dynamic drivers, a 20Hz–20,000Hz frequency range and 100dB sensitivity. The tuning is deliberately punchy — Back Bay calls it immersive, and the bass mode is meant to be flipped on for hard workouts. They also use sound isolation, so once they're seated you're getting the full wall of sound rather than a blend of music and the room around you. Latency is listed at 90 milliseconds, which matters if you're watching video on a treadmill or doing interval work to a guided app.
Battery is the headline number: 6 hours per bud plus a 24-hour charging case for 30 hours total, with USB-C charging and a quick-charge claim of 15 minutes for 90 more minutes of music. The case is compact — roughly 2.3 by 3.4 by 1.2 inches — and comes with a one-year warranty. Controls are touch-based: tap to skip, change volume, or take a call. Bluetooth 5.3 with a 30-foot range covers you across a normal gym floor.
The trade-offs are worth being honest about. They're rated IPX7, which handles rain and sweat, but Back Bay explicitly states they are not swimming earbuds — the fit isn't designed for it. And because they're in-ear with isolation, you lose awareness of your surroundings, which is the exact opposite of the AirWave Pro's pitch. If you run on open roads, that's a real consideration.
Side-by-Side: Which Should You Choose?
• Best for total battery life → Back Bay Audio Runner. 6 hours per bud plus a 24-hour case adds up to 30 hours; the AirWave Pro runs 17.5 hours on one charge with no case.
• Best for running without a phone → Langsdom Running Headphones AirWave. The 32GB built-in memory and OTG adapter let you load music directly onto the headphones.
• Best for bass and immersive sound → Back Bay Audio Runner. A dedicated bass boost mode, 10mm drivers and sound isolation are built for people who want the music to take over.
• Best for all-day comfort on long sessions → Langsdom Running Headphones AirWave. At 26 grams with a titanium alloy and silicone frame, the open-ear build is designed to reduce pressure over extended wear.
• Best for gym and treadmill use → Back Bay Audio Runner. Sealed in-ear fit plus touch controls and a charging case suit indoor sessions where you don't need to hear the room.
• Best for the toughest conditions → Langsdom Running Headphones AirWave. IP67 dust and water resistance covers dust as well as rain and sweat, where the Runner's IPX7 rating addresses water only.
• Best for easy charging habits → Back Bay Audio Runner. USB-C with a compact 650mAh case means you charge once and forget it; the AirWave Pro needs its magnetic cable when the 17.5 hours run out.
In my opinion, the choice comes down to one question: do you want to hear the world while you run, or shut it out? If it's the first, I'd buy the Langsdom Running Headphones AirWave — the open-ear fit, IP67 rating, dual-device pairing and 32GB phone-free playback mode make it the more versatile outdoor companion for me. If it's the second, and you want bass that hits plus a case that keeps everything topped up for weeks, the Back Bay Audio Runner is the better fit. I'd lean AirWave Pro for road running and Runner for the gym.
Back Bay Audio Runner has the higher total figure. Each bud plays for about 6 hours and the charging case holds another 24, for 30 hours overall. The Langsdom AirWave Pro is rated at up to 17.5 hours of continuous playback on a single charge, with no case involved.
Yes, based on their IP67 rating. That covers both dust and water, so sweat and rain are within spec. The Back Bay Runner is rated IPX7 for water resistance, but Back Bay notes it is not designed for swimming.
The design intent says yes. They use an ear-hook that wraps over the top of your ear, and Back Bay states the shape was developed with runners specifically to keep the buds secure. The sealed in-ear fit plus the hook is aimed at preventing them working loose.
No. It has 32GB of built-in memory, so you can load MP3 files onto it via the magnetic cable or the included OTG adapter and play music without a phone. The Back Bay Audio Runner has no built-in storage and needs a Bluetooth source.
