If you want a neckband-style running headphone with retractable earbuds, marathon-grade talk time and a vibration alert for incoming calls, choose BEARTWO Headphones; if you need a true wireless sport earbud with a secure ear-hook fit and full waterproofing, choose JBL Endurance Peak II.
• BEARTWO Headphones biggest strength: a neckband that sits on your shoulders with retractable earbuds, so the cable never dangles loose, plus 18 hours of talking time and 16 hours of music time per charge.
• BEARTWO Headphones biggest trade-off: it's an older Bluetooth 4.1 design (with 5.0 also listed), it is sweatproof rather than fully waterproof, and it is a neckband — you always have a collar of plastic and silicone on you.
• JBL Endurance Peak II biggest strength: true wireless freedom with an adjustable Powerhook ear hook, IPX7 sweatproof and waterproof protection, and 30 hours of combined playback (6 in the buds, 24 in the case).
• JBL Endurance Peak II biggest trade-off: the buds alone only hold 6 hours, there is no active noise cancellation, and you have to keep track of a charging case and two separate earpieces.
• Pick BEARTWO Headphones if you take lots of calls mid-run, want your earbuds tethered and retractable, and hate stopping to charge.
• Pick JBL Endurance Peak II if you want nothing on your neck, sweat hard or run in the rain, and want each bud to work independently.
The BEARTWO is a neckband headphone first and a running accessory second, and that order matters. The silicone band rests around your neck, and the earbuds pull out on retractable wires you can extend up to roughly 28 cm and snap back when you're done. For running, that solves the single most annoying thing about cheap wireless earbuds: nothing dangles, nothing snags on a jacket zip, and nothing disappears into a gym bag. The function keys sit on the outer surface of the neckband, so you can adjust volume or skip a track without hunting for a tiny button on a bud.
Battery is where this thing earns its place in a running rotation. BEARTWO lists 18 hours of talking time and 16 hours of music time, and a 3.5-hour charge. That's enough for a week of short daily runs on a single charge, and it's enough for a long run plus the commute home. The call vibration feature is genuinely useful if you run with your phone and take work calls: the headset buzzes when a call comes in, so you feel it against your neck even in a noisy street or with music up. The built-in mic uses CVC noise cancellation for calls, which is the kind of spec that helps most when you're talking into wind.
The rest of the spec sheet is honest about what this is. It's an in-ear dynamic driver with a 20 Hz to 20,000 Hz range, Bluetooth listed at both 4.1 and 5.0, a 10-meter range, touch-style button controls, and active noise cancellation listed among the noise-control features. It can pair with two Bluetooth devices at once, which is handy if you run with a phone and a watch. It ships with a hard carry case, three sizes of gel ear tips, a Micro USB charging cable and a user guide, and it's sweatproof with soft silicone materials — fine for sweat, but I would not treat it as rain-proof.
JBL Endurance Peak II: Who It's For
The Endurance Peak II is built around one idea: stay in your ears no matter what you do. The Powerhook design is an ear hook you adjust to your own size and comfort level, which is exactly the kind of fit a runner needs when they're moving their head, sweating, and bouncing down a hill. JBL pairs that with three sizes of ear tips and an enhancer, and the brand's own note is worth repeating: if the tips don't match your ear canals or the buds aren't seated properly, you won't get the intended sound or call quality. Fit is the whole game here.
The waterproofing is the headline. IPX7 means the buds survive sweat and rain, and JBL's own framing is that you can get as wet as you want. For anyone who runs in summer heat, does intervals, or lives somewhere it rains without warning, that's a real difference from a sweatproof-only neckband. Audio is a 16-ohm dynamic driver with a 20 Hz–20,000 Hz range and JBL Pure Bass tuning, so the low end is pushed forward — good for motivation on a hard effort, less neutral for anyone who wants a flat sound.
Battery is a two-part story. You get 6 hours in the buds and 24 hours in the charging case, for 30 hours of combined playback, with a 6-hour charge time. Six hours per bud session covers virtually any run, but on a long ultra or a full day out, the case has to come with you. Dual Connect is the other standout: either bud can take calls, adjust volume, or trigger your voice assistant, and it doesn't matter which one you pull out of the case first. There's no active noise cancellation and no headphone jack — it's wireless only, with touch/media controls on the buds.
Buy it if you want a true wireless sport bud with an adjustable lock-in fit and genuine water protection. Skip it if you want active noise cancellation, if you'd rather have one battery number that covers your whole day without a case, or if you know you'll lose small earbuds.
Side-by-Side: Which Should You Choose?
• Best for battery per charge → BEARTWO Headphones. 18 hours of talk time and 16 hours of music time in one wearable, no case required.
• Best for heavy sweat and rain → JBL Endurance Peak II. IPX7 waterproofing versus BEARTWO's sweatproof silicone build.
• Best for taking calls while running → BEARTWO Headphones. Vibration alert on incoming calls, CVC noise cancellation on the mic, and 18 hours of talk time.
• Best for a secure sport fit → JBL Endurance Peak II. The adjustable Powerhook ear hook is designed to lock the bud to your ear.
• Best for cable management → BEARTWO Headphones. Retractable earbuds with roughly 28 cm of pull-out wire and a hard carry case.
• Best for people who hate things on their neck → JBL Endurance Peak II. True wireless, no band, no wires.
• Best for two-device switching → BEARTWO Headphones. It can connect to two Bluetooth devices at the same time.
In my opinion, the JBL Endurance Peak II is the better running headphone for most people, because the two things that decide whether a running headphone survives your training are fit and water resistance, and it wins both: an adjustable ear hook and IPX7. I'd pick BEARTWO Headphones instead if my runs double as call time or if I want one charge to last a whole week of sessions — the vibration alert and 18 hours of talk time are genuinely hard to argue with, and the retractable buds are a smart, tidy design. Choose based on whether you want a neckband you live in or buds that disappear into your ears.
how to wear running headphones
Seat the earpieces so they're snug and sealed — on the JBL Endurance Peak II, adjust the Powerhook to your ear and try the ear tip sizes until the bud doesn't shift. On the BEARTWO, rest the neckband on your shoulders and pull the retractable earbuds out to a comfortable length. A loose fit hurts both sound and call quality.
how to run with headphones
Keep the fit secure before you start, route any cable so it can't catch on clothing, and set your volume low enough to hear traffic. The BEARTWO's retractable design keeps the wire controlled around your neck, while the Endurance Peak II's true wireless build removes cables entirely.
how to run without headphones
You don't need either product for this — run by feel, breathing and footfall, and use a watch or phone for pace cues. If you still want audio, keep one earbud out or the volume low; the JBL Endurance Peak II's Dual Connect lets you run with just one bud and still take calls.
how to connect shokz running headphones
That's a different brand, so I can't cover it here. For these two: power the headphones on and put them in pairing mode, then select them from your phone's Bluetooth list — the BEARTWO can pair with two Bluetooth devices at once, and the Endurance Peak II pairs as a true wireless set.
