If you want one headset that keeps your voice clear on calls all day, choose LEVN Headset; if you need headphones that survive the pool and store your music on board, choose kelankeke Bone Conduction Headphones. These two are built for completely different jobs, and once you see what each one actually does, the choice stops being close.
• LEVN Headset — biggest strength: A binaural over-ear design with an active noise cancelling mic, up to 65 hours of battery life, and a USB dongle that gives Bluetooth-free computers a stable connection.
• LEVN Headset — biggest trade-off: It's a work headset, not a sport headset. No water rating, and its 49-foot wireless range is fine for an office but limits it outdoors.
• kelankeke Bone Conduction Headphones — biggest strength: IPX8 waterproofing plus 32GB of built-in memory, so you can swim with music playing from the headphones themselves, no phone required.
• kelankeke Bone Conduction Headphones — biggest trade-off: Only 10 hours of playback, 10 meters of Bluetooth range, and no active noise cancellation — by design, since open-ear headphones are meant to let sound in.
• Who each pick is for: LEVN is for call-center agents, remote workers, and anyone who lives in Zoom and Teams. kelankeke is for swimmers, runners, and cyclists who want music without blocking out traffic or the pool.
The LEVN Headset is a communication tool first and a music device second. Its core claim is the noise cancelling microphone, which the manufacturer says eliminates 99.9% of background noise so the person on the other end hears your voice and not the dog, the kids, or the coffee shop. There's also a mute button for when you need to cough, sneeze, or say something that isn't for the meeting. In my opinion, that mute button matters more than most buyers realize — it's the difference between a headset you tolerate and one you actually trust on client calls.
The numbers here are aimed squarely at work. Up to 65 hours of battery life means you can run roughly eight hours of talk time a day for a full work week without reaching for a charger. The included POGO charging base is plug-and-play and has a dedicated slot for the USB dongle, which is a small design decision that solves a very real problem: losing the dongle. On connectivity, you get two paths — Bluetooth 5.2 for phones and laptops, or the USB adapter for desktops with no Bluetooth at all. Only one device connects at a time, and the wireless range is about 49 feet, which is plenty for pacing around a home office or grabbing coffee mid-meeting.
Who should skip it? Anyone who wants to swim, sweat heavily, or run in the rain. There's no IP rating on this headset, and it's an over-ear design that weighs 6.24 ounces — comfortable for a desk, less so for a treadmill. If your priority is movement and water, this isn't your product.
kelankeke Bone Conduction Headphones: Who It's For
The kelankeke E9 Pro is a different animal entirely. It's an open-ear bone conduction headphone, which means the drivers sit outside your ear canal and send sound through your cheekbones. That design keeps your ears open to the world around you — the brand positions this as a safety feature for running, cycling, and exercising, and that's a fair read. You hear the music and the car behind you at the same time.
The headline feature is the IPX8 waterproof rating. That's the top end of the water-resistance scale, and the manufacturer explicitly supports swimming, snorkeling, fishing, and boating, with a note that you can wear them with a swim cap, goggles, and earplugs. There's one critical catch you need to understand before buying: Bluetooth doesn't work underwater. You have to switch to MP3 mode by double-clicking the power button on land, before you get in the water. That's not a flaw so much as physics, but it trips people up.
Which is exactly why the 32GB of built-in storage exists. That's room for roughly 8,000 songs, supporting MP3, WMA, FLAC, APE, and WAV files. You copy music over by connecting the magnetic charging cable to your computer — the headphones show up as USB storage. So the workflow is: load your playlist, switch to MP3 mode, swim. No phone, no signal, no problem. The multi-function button handles play, pause, track skip, and call answer/hang up, and it also toggles between Bluetooth and MP3 modes.
Battery life is 10 hours of continuous playback with a 2-hour full charge via magnetic cable. Bluetooth is version 6.0 with a range of up to 10 meters (about 33 feet). The whole thing weighs just 27.8 grams — under an ounce — which is why it stays put during activity. Noise control is passive only, which is the point of an open-ear design.
Who should skip it? Anyone who needs to sound professional on calls. Bone conduction mics pick up a lot of your environment, there's no active noise cancellation, and the 10-hour battery is a fraction of what the LEVN offers. This is a fitness and swimming product, not an office product.
Side-by-Side: Which Should You Choose?
• Best for battery life → LEVN Headset. Up to 65 hours against 10 hours. Not a close contest.
• Best for swimming and water → kelankeke Bone Conduction Headphones. IPX8 waterproofing versus no water rating at all. This is the single biggest differentiator.
• Best for music without a phone → kelankeke Bone Conduction Headphones. 32GB of onboard storage lets you leave your phone in the locker.
• Best for all-day desk comfort and long shifts → LEVN Headset. Protein leather earcups, adjustable headband, and a charging base that keeps it topped up between meetings.
• Best for running, cycling, and situational awareness → kelankeke Bone Conduction Headphones. Open-ear design means you hear traffic and surroundings.
• Best for desktop computers without Bluetooth → LEVN Headset. The included USB dongle solves that problem directly. The kelankeke connects over Bluetooth only.
• Best for portability → kelankeke Bone Conduction Headphones. Under an ounce, versus 6.24 ounces for the LEVN.
If I were buying for myself and my job involved calls — client meetings, support queues, standing team standups — I'd buy the LEVN Headset. The noise cancelling mic, the mute button, the 65-hour battery, and the USB dongle all solve problems I'd actually have every single day. If I were buying for swimming laps or long outdoor runs, I'd buy the kelankeke Bone Conduction Headphones without hesitation, because IPX8 waterproofing and 32GB of built-in storage are things the LEVN simply can't do. In my opinion, most people shopping this comparison work from a desk, and that tips it to LEVN. Check the current price on Amazon before you commit — the button on this page will take you there.
FAQ
No. Bluetooth doesn't transmit underwater, so you must switch to MP3 mode — double-click the power button — before entering the water. Your music then plays from the built-in 32GB of storage.
They work differently. The LEVN uses active noise cancellation focused on its microphone, so callers hear less background noise. The kelankeke uses passive noise cancellation only, and its open-ear design intentionally lets outside sound in for safety.
Yes. That's what the included USB dongle is for — it gives you a stable, low-delay connection on computers without Bluetooth. Note that only one device can be connected at a time.
