How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a do-everything headset for calls, desk work and long listening sessions with a neckband you can fold away, choose BEARTWO Headset; if you need open-ear awareness, a featherweight fit and sweat resistance for running and outdoor workouts, choose Rhyfell Bone Conduction Headphones. That's the whole decision in one line. The rest of this page is the reasoning behind it, spec by spec.
• BEARTWO Headset — biggest strength: a retractable, foldable neckband design with a built-in microphone and passive noise cancellation, plus a quoted battery life that leaves the Rhyfell far behind.
• BEARTWO Headset — biggest trade-off: it's an in-ear, around-the-neck headset. It seals your ears, weighs 67 g, and it isn't water-resistant, so it's a poor fit for heavy sweat or cycling where you need to hear traffic.
• Rhyfell Bone Conduction Headphones — biggest strength: an open-ear, 28 g frame that sits off your ear canal, so you stay aware of your surroundings while you run, ride or lift.
• Rhyfell Bone Conduction Headphones — biggest trade-off: open-ear sound leaks in outside noise by design, there's no noise control at all, and it's a workout tool rather than a call-and-office headset.
• Who each pick is for: BEARTWO Headset for people who live on calls, listen for hours and want cable management and a carry case; Rhyfell Bone Conduction Headphones for runners, cyclists and gym-goers who value awareness and a barely-there fit.
The BEARTWO Headset is built around a neckband that curves around the back of your neck, with earbuds on retractable cords you pull out when you want them and let snap back when you don't. That one design choice tells you most of what you need to know. The cables can't tangle because they retract, and the whole thing folds down small enough to go in a pocket or the included carry case. If you've ever fished a knotted earbud cable out of a bag, you already understand why that matters.
On the audio side, BEARTWO uses a dynamic driver with a 20 Hz to 20,000 Hz frequency range and a high-sensitivity microphone with noise-cancelling technology — passive, not active, so it reduces some background noise but won't silence a busy street. Bluetooth 4.1 with CVC 6.0 handles the connection, and the stated range is 10 meters. The battery figures are the headline: up to 16 hours of continuous music and 300 hours of standby on a single charge, with around 3.5 hours to charge and an average life quoted at 18 hours. That's a full workday plus a commute, twice over, without hunting for a cable.
Who should buy it: commuters, remote workers, drivers and anyone who takes a lot of calls. It's also a sensible pick if you share a desk or office and want your audio contained rather than broadcast. Who should skip it: runners and cyclists who need to hear their surroundings, swimmers, and anyone who dislikes the feeling of earbuds sealing their ear canal. The ABS+PC build is light and soft, but at 67 g around the neck it's a presence you notice, and there's no water-resistance rating here.
Rhyfell Bone Conduction Headphones: Who It's For
The Rhyfell Bone Conduction Headphones take the opposite approach. Instead of pushing sound into a sealed ear canal, they sit against the bone in front of your ear and send vibrations straight to your inner ear. Your ear canal stays completely open. For a runner crossing a road, or a cyclist sharing a lane with traffic, that open-ear design is the entire point — you hear your music and the world at the same time.
The frame weighs 28 g, which is light enough that the spec sheet's "ultra-light" framing is fair rather than marketing noise. It uses upgraded skin-friendly materials, and the open-ear shape means nothing is jammed into your ear for an hour-long session. Bluetooth 6.0 is the newer wireless standard here, with a 10-meter range, and controls are physical buttons rather than touch — easier to find by feel with sweaty hands or gloves on.
Battery is quoted at up to 13 hours of playback at 80% volume, with a full recharge in about 2 hours over USB-C. That's a different philosophy from the BEARTWO: less total runtime, but a faster top-up and a modern connector. IPX5 water resistance means sweat and light moisture are fine — running, cycling, hiking and gym sessions are covered. It won't survive swimming or heavy rain.
Who should buy it: runners, cyclists, gym-goers and hikers who want awareness as a safety feature, and anyone who finds in-ear buds uncomfortable or prone to falling out. Who should skip it: people who want noise isolation on a plane or train, anyone who needs a microphone-first headset for back-to-back calls, and buyers who want bass that seals in. Bone conduction is not a bass-heavy technology, and with no noise control at all, a noisy commute will compete with your music.
• Best for battery life → BEARTWO Headset. Up to 16 hours of music and 300 hours of standby versus up to 13 hours of playback quoted for the Rhyfell.
• Best for running and cycling → Rhyfell Bone Conduction Headphones. The open-ear design and IPX5 sweat resistance are made for movement; the BEARTWO has no water rating.
• Best for calls and meetings → BEARTWO Headset. A built-in high-sensitivity microphone, CVC 6.0 and dual-phone pairing are all call-oriented features the Rhyfell doesn't list.
• Best for all-day comfort on a light frame → Rhyfell Bone Conduction Headphones. 28 g open-ear beats a 67 g neckband if weight is what bothers you.
• Best for cable management and portability → BEARTWO Headset. Retractable earbuds and a foldable body with a carry case versus a single fixed open-ear frame.
• Best for staying aware of traffic → Rhyfell Bone Conduction Headphones. Open ear, by design. The BEARTWO's passive noise cancellation works against you here.
• Best for charging convenience → Rhyfell Bone Conduction Headphones. USB-C and roughly a 2-hour charge, against roughly 3.5 hours for the BEARTWO.
• Best for quiet, focused listening → BEARTWO Headset. Sealed in-ear fit plus passive noise cancellation; the Rhyfell has no noise control.
If I had to pick one, I'd buy the BEARTWO Headset for general daily use and the Rhyfell only if my primary activity is running or outdoor training. The BEARTWO simply covers more of a normal day — calls, music, desk work, commuting — and its battery quote is far more forgiving. In my opinion, the Rhyfell is the better product for its narrow job: it's lighter, it's sweat-resistant, and the open-ear design is a genuine safety feature if you train near traffic. But if you're buying one headset to do everything, the neckband wins on versatility. Check the current price on Amazon before you decide, since that's the one variable I can't compare here.
No, and I wouldn't use it that way. The BEARTWO is in-ear with passive noise cancellation and no water-resistance rating, so sweat and blocked ambient sound both work against a runner. The Rhyfell's open-ear frame and IPX5 rating are purpose-built for it.
BEARTWO quotes up to 16 hours of continuous music and 300 hours of standby on one charge, with around 18 hours average life. Rhyfell quotes up to 13 hours of playback at 80% volume. Real numbers will vary with volume and use.
No. The spec sheet lists noise control as none — that's inherent to open-ear bone conduction, since your ear canal stays open. If you want isolation, the BEARTWO's passive noise cancellation is the closer match, though it's not active cancellation either.
The BEARTWO is clearly the call-first option, with a high-sensitivity microphone, CVC 6.0 and dual-phone pairing. Rhyfell is positioned around music and workouts, with button controls and no call features listed.
