How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want an affordable everyday pair of true wireless earbuds for the gym, a run in the rain, or taking calls on the go, choose Jectse Earbuds; if you need headphones that survive full underwater swimming and can play music without a phone at all, choose INDIVISO Bone Conduction Headphones.
• Jectse Earbuds — biggest strength: A traditional in-ear true wireless design with an IPX7 rating on the buds themselves, plus a 1200mAh charging case that Jectse says stretches total listening to around 24 hours.
• Jectse Earbuds — biggest trade-off: The charging case is not waterproof, talk time runs about 4 hours per charge, and there is no active noise cancellation — you get passive in-ear sealing only.
• INDIVISO Bone Conduction Headphones — biggest strength: IPX8 waterproofing rated for immersion up to 3 meters, a 32GB MP3 mode that plays roughly 9,000 songs with no phone, and Bluetooth 5.4 with dual-device pairing.
• INDIVISO Bone Conduction Headphones — biggest trade-off: Open-ear bone conduction means you hear everything around you and get no isolation; Bluetooth does not work underwater, so swimming forces you into MP3 mode.
• Who each pick is for: Jectse for the budget-conscious everyday listener who wants sealed, private sound; INDIVISO for the swimmer, cyclist or open-ear runner who wants music untethered from a phone.
The Jectse Earbuds are a classic true wireless setup: two small in-ear buds that live in a charging compartment. The headline spec is water resistance. The buds are rated IPX7, which means sweat and rain are not a concern — that rating is exactly why Jectse pitches them for fitness, trips and outdoor use. One caveat straight from the data sheet: the charging case itself is not waterproof, so you should not dunk the whole kit or leave it out in a downpour.
Battery is where the design gets interesting. Each bud carries a 50mAh battery and delivers roughly 4 hours of talk time, and the case holds a 1200mAh cell that Jectse says supports up to 24 hours of use on a single charge. In practice that means you can leave the wall charger at home for a day or two of commutes and workouts, dropping the buds back in the case between sessions. Charging takes about 1.5 hours.
Connection-wise, these run Bluetooth 5.1 with support for HSP, HFP, A2DP and AVRCP — the standard profiles that cover stereo music and hands-free calling. The transmission range is about 10 meters, and the buds pair with phones, tablets and laptops, including voice-assistant wake-up. Fast Pair means you pop them out of the case and they connect; the first time, Jectse notes you need to seat them in the case to wake them up before pairing.
Who should buy it: Anyone who wants simple, sealed in-ear listening for running, gym sessions, calls and general phone use, and who likes the idea of a case that doubles as a power bank for the buds.
Who should skip it: Swimmers and anyone who needs to hear traffic or training partners. There is no noise control listed, so there is no active cancellation, and the in-ear seal cuts you off from your surroundings. If you need music in the water, this is not the product.
The INDIVISO X7 is a different animal entirely. Instead of plugging your ears, it sits on your cheekbones and vibrates sound through bone, leaving your ear canal open. That open-ear design is the whole point: you stay aware of cars, other runners and poolside instructions while music plays. The build is plastic and silicone with an open-ear hook shape, and it weighs 4.8 ounces.
The standout feature is the 32GB of built-in storage. That turns these into a standalone MP3 player — INDIVISO says it holds up to 9,000 songs, so you can run or swim with no phone, no armband and no Bluetooth dropout. This matters because the data sheet is explicit that Bluetooth signals cannot travel underwater; when you swim, you must switch to MP3 mode. The IPX8 rating backs that up, with protection rated for immersion up to 3 meters for extended periods, covering pool laps, surfing and rain.
When you are out of the water, Bluetooth 5.4 handles the connection with a range of about 33 feet, and it supports simultaneous pairing to two devices so you can hop between a phone and a laptop without re-pairing. Battery is a 200mAh cell good for 8 hours of music or talk time and 72 hours of standby, recharged in about 2 hours through a magnetic waterproof charging port. Controls are touch-based, and INDIVISO includes a 1-year limited warranty.
Who should buy it: Swimmers first and foremost, then cyclists, runners and gym-goers who want open ears, phone-free playback, and one headset that works both wet and dry.
Who should skip it: Anyone who wants deep, isolated sound in a noisy office or on a plane. Bone conduction leaks sound and lets noise in by design. If you want to block out the world, this is the wrong tool.
• Best for swimming → INDIVISO. IPX8 rated for 3-meter immersion plus MP3 mode for underwater playback. Jectse's buds are IPX7, but the case is not waterproof and Bluetooth will not survive a lap.
• Best for all-day battery convenience → Jectse. The 1200mAh case supports up to 24 hours of use, so the buds recharge every time you put them away. INDIVISO runs 8 hours per charge and needs the magnetic cable.
• Best for situational awareness → INDIVISO. Open-ear bone conduction keeps your ear canal clear, which matters on roads and in shared training spaces.
• Best for private, sealed listening → Jectse. In-ear buds physically block outside noise; bone conduction cannot.
• Best for phone-free workouts → INDIVISO. 32GB of storage means roughly 9,000 songs with no device attached.
• Best for multi-device switching → INDIVISO. Bluetooth 5.4 with simultaneous two-device pairing beats Bluetooth 5.1 single-device connection.
• Best for quick everyday pairing → Jectse. Fast Pair and auto-connect from the case make short commutes and calls frictionless.
• Best for the widest range of casual use → Jectse. Calls, music, laptops, tablets, voice assistants — it covers the basics with less to think about.
If I had to pick one, I would buy the INDIVISO Bone Conduction Headphones. In my opinion, the combination of IPX8 waterproofing, a real 32GB MP3 mode and Bluetooth 5.4 dual-device pairing covers far more ground — pool, road, gym and desk — than a standard pair of true wireless buds can. The Jectse Earbuds are the smarter call only if you want sealed in-ear sound and a recharging case for ordinary phone-and-music duty and have no intention of going underwater. Everyone else should pay the swim tax and take the INDIVISO.
FAQ
No. The buds are IPX7, which covers sweat and rain, but the charging case is not waterproof and the design is not intended for immersion. For swimming, you want the INDIVISO's IPX8 rating.
Yes. The built-in 32GB MP3 mode plays stored music directly, with no phone or Bluetooth connection needed. That is also how you listen while swimming, since Bluetooth does not transmit underwater.
It depends on how you count. Jectse lists about 4 hours of talk time per bud charge, with the 1200mAh case supporting up to 24 hours overall. INDIVISO lists 8 hours of continuous music or talk time plus 72 hours of standby.
Yes. Jectse supports the standard hands-free profiles for stereo calls, and INDIVISO lists 8 hours of talk time over Bluetooth 5.4 with two-device pairing. Note that calls only work over Bluetooth — not in the water.
For indoor or dry outdoor training, the Jectse Earbuds give you a sealed fit and a charging case. If you run on roads or want your ears open to traffic, the INDIVISO's open-ear design is the better fit.
