• MONODEAL's biggest strength: a genuinely IP68-rated, bone-conduction open-ear design that works underwater in MP3 mode, with 32GB of built-in memory so you don't need your phone at the pool.
• MONODEAL's biggest trade-off: Bluetooth simply doesn't transmit underwater, so you're locked to MP3 mode while swimming, and there's no active noise cancellation.
• BUGANI's biggest strength: up to 50 hours of total playtime with the charging case and a light, hook-style open-ear fit that's comfortable for hours of running.
• BUGANI's biggest trade-off: IPX5 means sweat and splashes are fine, but it's not built for swimming or heavy rain, and it relies on your phone via Bluetooth at all times.
• Pick MONODEAL if swimming, showering, or wet-weather training is part of your routine.
• Pick BUGANI if running, gym work, and long listening sessions matter more than water resistance.
The MONODEAL S820 is the more specialized tool of the two. Its headline feature is a professional IP68 waterproof rating, and the specs back it up: immersion up to 2 meters for 2 hours. That's a real swimming headphone, not a "sweat-resistant" one. It uses bone conduction drivers with a frequency range of 20 Hz to 20,000 Hz, sitting over your ears rather than inside them, so your ear canals stay open and you keep hearing what's going on around you.
The catch is one you need to understand before buying: Bluetooth doesn't travel through water. MONODEAL solves this with 32GB of built-in MP3 memory, so while you're in the pool you switch to MP3 mode and play music stored on the headphones themselves. In the description, that's spelled out clearly — use MP3 mode when swimming. Out of the water, you get Bluetooth 5.4 for normal wireless listening and calls, with a built-in microphone. Battery life is rated at 8 hours per charge, with a 2-hour charge time, and the whole thing weighs just 24 grams with silicone construction.
BUGANI Open Ear Earbuds: Who It's For
The BUGANI OWSB15S plays a different game entirely, and it plays it well. Its defining number is 50 hours of total playtime with the portable charging case, charged in about 1.5 hours. For a runner, that's the difference between charging every couple of days and charging once a week or less. The earbuds themselves are open-ear with soft, adjustable ear hooks, and BUGANI specifically notes the fit works even when you're wearing glasses — a detail a lot of open-ear designs get wrong.
Audio comes from a 13mm dynamic driver with 360° surround stereo tuning, directional audio to reduce sound leakage, 32 ohm impedance, 98 dB sensitivity, and a 20 Hz frequency response with roughly 1 millisecond of latency. In practice, that combination points to a lively, bass-forward sound that stays reasonably private at moderate volumes, and latency low enough that video and calls shouldn't feel badly out of sync. Bluetooth 5.4 handles pairing, with a stated range of 33 feet, and controls are touch-based on the earpiece — tap for volume, track skipping, and calls, plus voice assistant support.
The trade-off is water protection. Despite the listing title mentioning IPX5, the feature text describes an IP54-rated design that protects against sweat and splashes. Either way, this is not a swimming headphone and I wouldn't treat it as one. There's also passive noise cancellation only, which for an open-ear design is really just a way of saying "you hear your surroundings" — fine for running safety, less ideal if you want to block out a noisy gym.
Buy the BUGANI if you're a runner, gym-goer, or commuter who wants long battery life, a comfortable hook fit, and the freedom of touch controls. Skip it if you swim, shower in your headphones, or train in heavy rain.
Side-by-Side: Which Should You Choose?
• Best for battery life → BUGANI Open Ear Earbuds. Up to 50 hours total with the charging case versus 8 hours per charge on the MONODEAL.
• Best for running in the rain or heavy sweat → MONODEAL Swimming Headphones-IP68. IP68 leaves far more margin than IPX5/IP54.
• Best for glasses wearers and long wear sessions → BUGANI Open Ear Earbuds. Adjustable ear hooks are explicitly designed to work over glasses.
• Best for phone-free workouts → MONODEAL Swimming Headphones-IP68. The 32GB of built-in memory means no phone required at all.
• Best for touch controls and voice assistant → BUGANI Open Ear Earbuds. Tap controls plus built-in voice assistant support; the MONODEAL uses remote-style media, call, and volume controls.
• Best for the lightest possible fit → MONODEAL Swimming Headphones-IP68. At 24 grams, it's exceptionally light for an over-ear open design.
• Best warranty coverage → BUGANI Open Ear Earbuds. A 2-year manufacturer warranty versus 1 year on the MONODEAL.
In my opinion, the right pick comes down to one question: does water ever touch your headphones? If yes, buy the MONODEAL Swimming Headphones-IP68 — nothing about the BUGANI's IPX5/IP54 rating suggests it belongs in a pool, and the 32GB MP3 mode is a genuinely clever answer to Bluetooth's underwater problem. If water never touches your headphones and you're a runner who hates charging, buy the BUGANI Open Ear Earbuds for the 50-hour playtime and the glasses-friendly fit. Two different jobs, two different answers — I'd choose based on my wettest workout, not my driest one.
FAQ
how to run with earbuds
how to run with wired earbuds
Neither of these is wired — both are wireless Bluetooth models, and the MONODEAL also has no headphone jack at all. If you specifically want a wired setup, you'd need a different product entirely. For running, wireless open-ear is generally the more practical choice since there's no cable to snag.
how to connect jbl running earbuds
That's a different brand, so the exact steps won't match these two. The general Bluetooth 5.4 process is the same, though: put the earbuds in pairing mode and select them from your phone's Bluetooth menu. The BUGANI and MONODEAL both use Bluetooth 5.4 for fast pairing.
how to pair jaybird run earbuds
Again, different product line — but pairing logic carries over. Power the earbuds on, enable Bluetooth on your device, and pick the headphones from the list. Both models here support Bluetooth 5.4, which is the current standard for quick, stable connections in crowded areas.
