How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want maximum waterproof protection for swimming and the sweatiest sports, choose H2O Audio Surge SX10; if you need an open-ear wireless earbud for all-day comfort with Bluetooth 5.4 and AI noise cancellation, choose ROEL-PLAY in-Ear Open Fit.
• H2O Audio Surge SX10 — biggest strength: IPX8 waterproofing with full submersion to 12 ft / 3.6 m, plus a short 1 ft / 30 cm cord and over-the-ear wire built specifically for swimming and hard workouts.
• H2O Audio Surge SX10 — biggest trade-off: It's a wired design with a 3.5 mm jack, so you'll need a head-mounted player or a device with a headphone jack — no true wireless freedom.
• ROEL-PLAY in-Ear Open Fit — biggest strength: Open-ear hook design that stays outside your ear canal, Bluetooth 5.4 wireless, dual-driver Hi-Fi sound and AI noise cancellation with a 15 m range.
• ROEL-PLAY in-Ear Open Fit — biggest trade-off: Only 4 hours of battery average life, and its open-ear build means it's built for everyday listening and calls — not for underwater use or heavy submersion.
• Who each pick is for: Pick the Surge SX10 if you swim or need sweat-proof, secure wired audio; pick the ROEL-PLAY if you want comfortable wireless earbuds for daily wear, commuting, calls and light workouts.
The Surge SX10 is a specialist, and it doesn't pretend otherwise. Its headline feature is IPX8 — the highest waterproof rating — which means it handles heavy perspiration and complete submersion up to 12 ft / 3.6 m. That's a rare thing in the earbud world. It uses dynamic drivers custom-developed for water-sport use, with a frequency range of 20 Hz to 20,000 Hz and bass-forward tuning that H2O Audio designed to cut through water and movement noise.
The fit story is just as deliberate. An over-the-ear wire conforms to your ear, and the cord is only about 1 ft / 30 cm long, which keeps it from tangling or dragging while you run, swim or lift. H2O Audio also throws in a serious eartip assortment — memory foam tips in three sizes, silicone ear tips in five sizes, and "tree" tips in three sizes — so you can dial in a seal that stays put through flip turns. The T-jack and flat speaker profile are designed to reduce drag and wire noise.
So who should buy it? Swimmers first, and swimmers above all. Also anyone doing high-sweat sports — running in summer heat, cycling, weights — who wants wired reliability and a jack that plugs into a head-mounted MP3 player. Who should skip it? If you want true wireless freedom or you mainly take calls on the go, this isn't the tool. It's a wired, 3.5 mm, sport-first design, and its strengths live in the water and in the gym, not on a commute.
The ROEL-PLAY in-Ear Open Fit plays a completely different game. Instead of plugging into your ear canal, it uses an open-ear hook structure that sits outside the ear hole — the brand's whole pitch is no swelling, stuffiness or pain even after all-day wear. The frame is lightweight and ergonomic, with a curved hook that grips the contour of your ear so it stays stable during workouts while still letting you hear the world around you.
Wireless is where it shines. Bluetooth 5.4 is the newest version in this comparison, with a 15 m range and improved transmission that the brand says resists dropouts and stuttering. You get dual-driver Hi-Fi sound with a dynamic driver setup, directional sound transmission plus reverse sound-wave cancellation for reduced sound leakage and ambient noise suppression, and dual AI noise reduction for clearer calls. There's also an AI real-time translation function that sets it apart from almost anything else in the sport category.
Battery is the honest weak point: 4 hours average life, softened by rapid flash charging and a real-time battery level display. That's fine for a workout, a commute or a work session, but not for a marathon day. Who should buy it? Commuters, call-heavy workers, gamers who want low-latency audio-video sync, and anyone who wants open-ear awareness during cycling or light exercise. Who should skip it? Swimmers, and anyone who needs all-day battery — 4 hours won't cover it.
• Best for swimming → H2O Audio Surge SX10. IPX8 and 12 ft / 3.6 m submersion is unmatched here.
• Best for all-day comfort → ROEL-PLAY in-Ear Open Fit. Open-ear hooks avoid ear-canal pressure entirely.
• Best for wireless freedom → ROEL-PLAY in-Ear Open Fit. Bluetooth 5.4 with a 15 m range versus a wired 3.5 mm jack.
• Best for sweat-heavy gym and running → H2O Audio Surge SX10. IPX8 sweatproofing plus an over-ear wire that resists drag.
• Best for clear calls in noisy places → ROEL-PLAY in-Ear Open Fit. Dual AI noise reduction targets voice and cuts ambient noise.
• Best for plugging into an MP3 player → H2O Audio Surge SX10. The short cord and T-jack were built for head-mounted players.
• Best for battery endurance → H2O Audio Surge SX10. No battery to run down; the wired connection just works.
• Best for gaming and travel versatility → ROEL-PLAY in-Ear Open Fit. Low-latency sync, translation and multi-device compatibility.
In my opinion, the right pick comes down to one question: will these get wet? If you swim, or you want the toughest sweat protection and don't mind a wire, I'd buy the H2O Audio Surge SX10 — its IPX8 rating and sport-specific fit are exactly what punishing sessions demand. If your life is wireless — commuting, calls, gaming, light workouts — I'd buy the ROEL-PLAY in-Ear Open Fit for its open-ear comfort and Bluetooth 5.4. Just accept the 4-hour battery as the price of admission. Match the tool to your sport, and you'll be happy either way.
How to use sports headphones
Match the fit to the activity first: the Surge SX10 gives you memory foam, silicone and tree tips in multiple sizes to lock in a seal, while the ROEL-PLAY uses an open-ear hook that rests outside the canal. For water use, keep the SX10's 3.5 mm jack plugged into a head-mounted player. For wireless, pair the ROEL-PLAY over Bluetooth 5.4 and keep your phone within 15 m.
How to wear running headphones
The Surge SX10 is designed to be worn with the over-the-ear wire conforming to your ear and the short 1 ft / 30 cm cord kept close to your head so it doesn't tangle. The ROEL-PLAY is worn by hooking the curved arm over your auricle so it stays stable during strenuous workouts while leaving your ear canal open.
How to pair jlab sport headphones
I can't walk you through JLab models — this comparison covers the H2O Audio Surge SX10 and the ROEL-PLAY in-Ear Open Fit. For the ROEL-PLAY, power it on, open your device's Bluetooth settings and select the M127. The Surge SX10 is a wired 3.5 mm headphone, so it needs no pairing at all.
How to charge impact sport headphones
The ROEL-PLAY in-Ear Open Fit charges via rapid flash charging and shows a real-time battery level display so you can track the 4-hour average life. The H2O Audio Surge SX10 has no battery — it's a wired 3.5 mm design, so there's nothing to charge.
