If you want to keep your ears open to traffic, trail and training partners, choose Rhyfell Bone Conduction Headphones; if you need deep bass, call clarity and a charging case that keeps going for days, choose PEFUPEW Earbuds.
Both are built for sweat. They just solve the problem in opposite ways. One sits on your cheekbones and leaves your ear canal empty. The other plugs in, hooks over your ear and brings a case along for the ride. Which one belongs in your gym bag depends entirely on how you train.
• Rhyfell's biggest strength: an open-ear, 28g frame that lets outside sound in — genuinely useful on roads, trails and in busy gyms.
• Rhyfell's biggest trade-off: no noise cancellation at all (the spec sheet lists it as "None"), so loud environments will fight your music.
• PEFUPEW's biggest strength: a 48-hour total battery figure with a charging case, plus four ENC mics for calls.
• PEFUPEW's biggest trade-off: it's a sealed in-ear design with ear hooks — more parts to manage, and you lose that ambient awareness.
• Pick Rhyfell if safety and situational awareness matter more than bass.
• Pick PEFUPEW if you want loud, full sound and long battery life for indoor or treadmill sessions.
The Rhyfell set is a single-piece open-ear headphone. There's no case, no silicone tips, no pairing dance with a lid. You put it on, you press a button, you go. The frame weighs 28g and uses ABS plastic, and the whole thing is designed around staying put while you move — running, cycling, gym work, hiking.
The two numbers that matter most here are the 13 hours of playback at 80% volume and the IPX5 rating. Thirteen hours covers a lot of long rides and multi-session days, and a full recharge takes about two hours over USB-C. IPX5 means sweat and light moisture are fine — it's built for workouts, not for swimming or for leaving in the rain. Bluetooth 6.0 with a 10-meter range is the connection spec.
The real feature, though, is the open-ear design. Nothing enters your ear canal, so traffic, approaching cyclists, gym announcements and your own breathing all come through. For anyone who runs on roads or rides near cars, that's not a gimmick — it's the reason to buy this instead of earbuds. Button controls are also worth noting: physical buttons are far easier to find by feel with sweaty hands or gloves than touch panels.
Who should skip it: if you train mostly in a loud gym and want your music to block out the room, or if you care about deep, thumping bass. Bone conduction sends vibration through your cheekbones, and the spec sheet explicitly lists noise control as "None." There's no isolation here, by design.
PEFUPEW Earbuds: Who It's For
PEFUPEW takes the conventional route and then loads it up. These are over-ear hook buds — a 14.2mm dynamic driver in each ear, ear hooks to hold them in place, and silicone earplugs in three sizes (S/M/L) included. The hooks plus the tips are the stability story: the tip seals the canal for sound, the hook stops it from moving during hard effort.
The spec sheet is aggressive on paper. Bluetooth 5.4 with a claimed 40-millisecond audio delay and a 15-meter range. Four ENC microphones that the listing says cut 80% of background noise for calls. A 43% bass boost claim tied to a three-layer composite diaphragm. Passive noise cancellation and sound isolation from the sealed fit. Touch controls with a claimed 22.5% accuracy improvement.
Battery is the headline. Each bud runs up to 8 hours at 50% volume, the case adds 4–5 more charges, and the total playback figure is 48 hours. Charging is USB-C and takes about 1.5 hours, with dual LED displays on the case so you can see the level. The whole kit — case and buds — weighs 58g, and the case itself measures roughly 5.5cm by 3cm by 8cm.
IP7 waterproofing is the other big one. That's a higher water-resistance rating than the Rhyfell set's IPX5, and it's the spec that matters if you sweat heavily or get caught in the rain. The ear hook design is also pitched specifically at reducing ear canal pressure for long wear.
Who should buy it: gym-goers, treadmill runners, indoor cyclists, commuters and anyone who wants a sealed, bass-forward listen with a case that lasts most of a week. Also the better pick if you take calls mid-workout — four mics and ENC processing are aimed squarely at that.
Side-by-Side: Which Should You Choose?
• Best for outdoor safety and awareness → Rhyfell Bone Conduction Headphones. Open-ear means traffic and surroundings stay audible.
• Best for battery life → PEFUPEW Earbuds. 48 hours total with the case beats 13 hours of single-charge playback.
• Best for water and sweat resistance → PEFUPEW Earbuds. IP7 outranks IPX5.
• Best for long single sessions without a case → Rhyfell Bone Conduction Headphones. One charge, up to 13 hours at 80% volume, no case to carry.
• Best for calls during workouts → PEFUPEW Earbuds. Four ENC microphones versus no microphone noise handling specified on the Rhyfell.
• Best for sound quality and bass → PEFUPEW Earbuds. A 14.2mm driver, three-layer diaphragm and a sealed fit will deliver far more low end than bone conduction.
• Best for simplicity and controls → Rhyfell Bone Conduction Headphones. Physical buttons, one piece, nothing to lose.
• Best for gym and indoor training → PEFUPEW Earbuds. Isolation plus ear hooks plus a long-lasting case fit that environment better.
If I were buying for myself, I'd take the Rhyfell Bone Conduction Headphones. The reason is simple: most of my training happens outdoors, and the open-ear design means I can hear cars, other people and my surroundings without pulling a bud out every few minutes. The 28g frame and 13-hour single-charge battery cover long sessions, and physical buttons just work with sweaty hands. If your training is indoors — gym, treadmill, spin bike — and you want bass and a case that lasts days, the PEFUPEW Earbuds are the smarter buy. In my opinion, the deciding question isn't sound quality. It's whether you want your ears open or closed.
how to use sports headphones
Charge them first — the Rhyfell set takes about 2 hours over USB-C, the PEFUPEW case about 1.5 hours. Then power on, put them in pairing mode, and connect from your phone's Bluetooth menu. Both pair wirelessly: Rhyfell over Bluetooth 6.0, PEFUPEW over Bluetooth 5.4.
how to wear running headphones
With the Rhyfell set, the frame rests on your cheekbones with your ear canal left open. With the PEFUPEW earbuds, push the tip into your ear and loop the hook over the top of your ear — three tip sizes (S/M/L) are included so you can seal the fit properly. A correct fit is what stops either one from shifting mid-run.

This page compares Rhyfell and PEFUPEW, so I can't walk you through JLab's pairing steps. The general routine is the same across brands: put the headphones in pairing mode, open Bluetooth settings on your device, and select them from the list. For JLab-specific steps, check that brand's own manual.
