• swimaudios Swimming Ear Buds — biggest strength: a genuine IPX8 waterproof, fully sealed bone-conduction design with 32GB of built-in MP3 storage, so you get audio underwater without needing a Bluetooth signal.
• swimaudios Swimming Ear Buds — biggest trade-off: it's a specialist tool. No multipoint, no noise cancellation, button/touch controls, and Bluetooth only works out of the water.
• Baseus Bass BC1 — biggest strength: multipoint connection, a 38-hour battery rating, 4-mic AI call clarity and a 5.3g clip-on fit that stays put during workouts.
• Baseus Bass BC1 — biggest trade-off: IP55 only. That resists sweat, dust and splashes — it is not built to be submerged, so swimming is off the table.
• Pick swimaudios if swimming or triathlon training is the whole point, and you want one device that handles both underwater laps and land workouts.
• Pick Baseus Bass BC1 if you want open-ear comfort for work calls, commuting, running and the gym, and you regularly switch between a laptop and a phone.
This is a bone-conduction headset built around one job: keeping audio going when Bluetooth can't. The IPX8 rating means it's fully sealed and designed for pool training, open-water swimming and triathlon, with sound carried through the bone rather than the ear canal. As a spec, that's the whole reason it exists — Bluetooth signals die the moment your head goes under, which is why the 32GB of built-in MP3 storage matters far more here than any wireless feature.
On land it flips into a normal open-ear sport headset over Bluetooth 5.4, with a 10-meter range and hands-free calling. Battery is rated 15 hours, with a 1.5-hour charge time via the magnetic cable, and the wrap-around titanium frame keeps the weight at 1.4 ounces so it stays put through freestyle, flip turns and sprints. The package includes the headset, a magnetic charging cable, earbud sets, an adjustable strap and a manual, and it carries a 1-year warranty.
Who should buy it: swimmers, triathletes, and anyone who trains in water and wants music without a phone nearby. Loading tracks is drag-and-drop over the magnetic USB cable, so you curate a playlist once and you're set. Who should skip it: if you never get in the water, you're paying for waterproofing and MP3 storage you won't use. There's no noise cancellation, no multipoint pairing, and only one device connection at a time — so if your day is laptop-to-phone-to-tablet hopping, this isn't the tool for that.
The Bass BC1 is the opposite philosophy: it never goes underwater, but it's built to be worn all day, everywhere else. The open-ring clip design sits outside your ear canal, which means you keep awareness of traffic, coworkers and surroundings while music plays. Baseus specifically calls out glasses wearers and earring lovers here, and that's a real design decision — nothing presses into the ear, so there's no pressure point to fight with your frames.
The fit is handled by a tri-curve ergonomic clip and a flexible TPU C-ring that grips gently across different ear shapes, at 5.3g per bud. Sound comes from 12mm dynamic drivers with bio-cellulose diaphragms and AI bass boost, plus directional delivery to limit leakage. Four microphones with AI noise reduction handle calls, and Bluetooth 6.0 gives a 10-meter range. Battery is rated 38 hours, and IP55 covers dust, sweat and splashes. Warranty is 2 years.
The feature that separates it from the swimaudios set is multipoint pairing. That means the Bass BC1 can hold a connection to two devices at once — say your laptop and your phone — and switch between them without repairing. If you take a call on your phone mid-meeting and then go straight back to laptop audio, that's the scenario multipoint exists for. It's the single most practical difference between these two products for anyone who works across devices.
Who should buy it: commuters, remote workers, gym-goers, runners, and anyone who wants open-ear comfort plus reliable call quality. Who should skip it: swimmers, and anyone who needs deep passive isolation or active noise cancellation — this is an open design with no noise control, so it's the wrong tool for blocking out a plane cabin.
• Best for swimming → swimaudios Swimming Ear Buds. IPX8 and sealed for underwater use up to 3 meters; the Bass BC1 is IP55 and not submersible.
• Best for multipoint pairing → Baseus Bass BC1. It holds two device connections at once, so you can move between phone and laptop without repairing.
• Best for battery life → Baseus Bass BC1. Rated 38 hours versus 15 hours on the swimaudios set.
• Best for underwater audio without a phone → swimaudios Swimming Ear Buds. 32GB of MP3 storage plays directly from the headset when Bluetooth drops out.
• Best for call clarity → Baseus Bass BC1. Four microphones with AI noise reduction is a call-focused design; the swimaudios set lists no noise control at all.
• Best for glasses and earrings → Baseus Bass BC1. The open-ring clip avoids ear-canal pressure by design.
• Best for triathlon and open-water training → swimaudios Swimming Ear Buds. The titanium wrap-around frame and 1.4-ounce weight are built to survive flip turns and sprints.
• Best for all-day wear and commuting → Baseus Bass BC1. 5.3g per bud, IP55, and a 2-year warranty suit daily grind use far better.
If I had to pick one, I'd buy the Baseus Bass BC1 — because multipoint pairing, 38 hours of rated battery and 4-mic call clarity cover the way most people actually use headphones every single day. In my opinion, it's the more versatile product for work, commuting and training. But I'd only say that if you don't swim. If lap swimming or open-water training is your main reason for buying, the swimaudios Swimming Ear Buds are the right call — nothing about the Bass BC1's IP55 rating can substitute for IPX8 and onboard MP3 playback. Check the current price on Amazon before you commit, since that's the one variable that can flip this decision.
how to pair multiple headphones
Pairing multiple headphones usually means pairing each one to the same source separately, then selecting the active one from your device's Bluetooth menu — most phones and computers only output to one audio device at a time. If you want two earbuds connected simultaneously without switching menus, you need a model with multipoint pairing, like the Baseus Bass BC1. The swimaudios Swimming Ear Buds connect over Bluetooth 5.4 but do not list multipoint support.
how to pair multiple headphones iphone
On iPhone, open Settings, go to Bluetooth, and pair each headset one at a time; iOS will keep them in the device list, and you tap the one you want to use. There's no built-in way to stream to two sets of earbuds at once from an iPhone. For switching between an iPhone and a second device like a laptop without repairing each time, multipoint on the Bass BC1 is the feature to look for.
how to pair multiple headphones on ipad
The iPad works the same way as the iPhone: Settings, Bluetooth, pair each device individually, then select the active one. If you're moving between an iPad and a phone during the day, a multipoint headset such as the Baseus Bass BC1 can hold both connections and hand audio back and forth. The swimaudios Swimming Ear Buds are better suited to swimming and single-device Bluetooth use than to multi-device juggling.
how to pair multiple bluetooth headphones
You generally can't run two Bluetooth headsets on one phone at the same time for the same audio stream — you pair them individually and switch. What you can do is use a headset that supports multipoint, which keeps two sources connected so the audio follows you. That's the practical distinction: multipoint is about switching between devices, not doubling up on one.
