How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a lightweight neckband headset you can wear for hours and forget about, choose BEARTWO Headset; if you need true active noise cancellation and a secure ear-hook fit for hard workouts, choose GNMN Active Noise Cancelling.
• BEARTWO Headset — biggest strength: a foldable, retractable neckband design with up to 16 hours of continuous music time and 300 hours of standby, plus a carry case that weighs just 30 g.
• BEARTWO Headset — biggest trade-off: its noise cancellation is passive only. There is no active noise cancellation and no transparency mode, so loud gyms or busy streets will bleed through.
• GNMN Active Noise Cancelling — biggest strength: upgraded active noise cancellation with a depth of up to 45dB, a transparency mode, and up to 96 hours of total playback with the charging case.
• GNMN Active Noise Cancelling — biggest trade-off: it is a true-wireless earbud, so it depends entirely on its charging case and needs to be stored and recharged rather than folded into a pocket.
• Who BEARTWO is for: commuters, office users and casual exercisers who want one pair of headphones they can leave around their neck all day.
• Who GNMN is for: runners, lifters and sweaty-activity athletes who want ear hooks, water resistance and the ability to silence a noisy environment.
The BEARTWO Headset is built around a neckband. The frame sits around the back of your neck, the earbuds retract into it, and the whole thing folds down into the included carry case. In my opinion that single design decision is what makes it worth a look for sports and exercise: there is nothing loose to drop, nothing to lose in a gym bag, and no cable to untangle because the retractable earbuds pull out and reel back in on demand.
The specs back up the all-day angle. You get up to 16 hours of continuous music time and 300 hours of standby from a single charge, with a full charge taking about 3.5 hours. The average battery life figure listed is 18 hours. Bluetooth 4.1 with CVC 6.0 handles the connection and call clarity, and the 20 Hz – 20,000 Hz dynamic driver range covers the full audible spectrum. Pairing is straightforward and, notably, the headset can be paired with two phones at once — useful if you carry a work phone and a personal one. The 67 g body is made from ABS and ABS+PC, and it is designed to contour to the neck for long wear. Controls are touch-based, and the built-in microphone uses noise-canceling technology for calls. To be clear about what that means: it is noise cancellation for the mic, not active noise cancellation for your ears. The product sheet lists passive noise cancellation.
Who should buy it: someone who wants a grab-and-go headset for the gym, a walk, or a noisy open office, and who values battery headroom and cable management over total silence. If you take calls while moving and hate fiddling with tiny buds, this design is genuinely easier to live with.
Who should skip it: anyone who needs to actually block out a loud environment. Without ANC or transparency mode you get whatever the earbud seal provides. And if you dislike anything touching your neck while you run, the neckband will bother you.
The GNMN Active Noise Cancelling earbuds are the opposite philosophy: two independent buds, a charging case, and a spec sheet aimed squarely at athletes. The headline is the active noise cancellation, rated at a depth of up to 45dB, with three modes — ANC, Transparency and Normal — switched by tapping the left or right function button four times. Transparency mode lets you hear your surroundings without pulling the buds out, which is the feature I would actually use most on a run near traffic.
The fit is the other half of the story. The earpieces are hook-shaped, and GNMN ships S, M and L ear tips so you can size them to your ears. Combined with the ear hooks, the goal is a secure fit that survives intense, sweaty activity without falling out. The set carries an IPX7 waterproof rating, which is the strongest protection level in this comparison and directly relevant to workout use.
Audio comes from a 16mm speaker driver in an in-ear structure, with a large chamber acoustic design that balances internal and external air pressure to reduce sound loss. Battery is 8 hours on a single charge and up to 96 hours of continuous playback with the case, and the case has a dual LED display showing the real-time battery level of both the case and the buds. Charging is over USB-C. Pairing is automatic on removal from the case, and you can run both buds in stereo or pop one in and leave the other ear free.
Who should buy it: runners, cyclists, gym-goers, and anyone whose priority is cancelling noise on a flight or in a loud gym. The ear-hook design, IPX7 rating and transparency mode are all pointed at movement.
Who should skip it: anyone who resents charging a case, or who prefers a single piece of hardware they can drape around their neck. If you lose small objects easily, true-wireless buds are a worse bet.
• Best for battery life per charge → BEARTWO Headset (up to 16 hours continuous on one charge versus 8 hours for the GNMN buds alone).
• Best for total battery with the case → GNMN Active Noise Cancelling (up to 96 hours of continuous playback with the charging case).
• Best for blocking out noise → GNMN Active Noise Cancelling (active noise cancellation up to 45dB, plus a transparency mode).
• Best for call clarity in wind and noise → BEARTWO Headset (CVC 6.0 and a high-sensitivity microphone).
• Best for sweaty workouts → GNMN Active Noise Cancelling (IPX7 waterproof and ear-hook retention).
• Best for all-day wear and commuting → BEARTWO Headset (67 g neckband, body-contoured fit, retractable earbuds).
• Best for pairing multiple devices → BEARTWO Headset (explicit two-phone pairing procedure).
• Best for runners who need to hear traffic → GNMN Active Noise Cancelling (one-tap transparency mode).
If I had to pick one for sports headphones specifically, I would buy the GNMN Active Noise Cancelling. The ear-hook fit, IPX7 waterproofing and 45dB active noise cancellation are exactly the three things that matter when you are moving and sweating, and the transparency mode makes outdoor training safer. The 96-hour total playback with the case removes any battery anxiety.
I would choose the BEARTWO Headset instead if my "sport" is closer to commuting, walking and light gym work, and I want one durable object I can fold away, leave around my neck and charge every few days. It is the more convenient everyday object; the GNMN is the more capable athletic tool. Whichever direction you lean, check the current price on Amazon before deciding, since that is the one variable that can flip this call.
how to use sports headphones
Match the fit to the activity first — for the GNMN buds that means picking the right ear tip size (S, M or L) and seating the ear hooks, then switching to ANC for indoor work or Transparency for outdoor work by tapping the function button four times. For the BEARTWO neckband, pull the retractable earbuds out, seat them, and use the touch controls for volume and track skipping.
how to wear running headphones
Running headphones should sit secure enough that they do not shift when you sweat. The GNMN earbuds use hook-shaped earpieces plus swappable tips for a snug, contoured fit, and their IPX7 rating means sweat and rain are not a concern. The BEARTWO neckband instead keeps the weight on your neck, so the earbuds only need to seal, not grip.
how to pair jlab sport headphones
I can only speak to the two products here, not JLab. For the BEARTWO Headset, pair the first phone, then switch the headset off, turn off that phone's Bluetooth, pair the second phone, and finally re-enable Bluetooth on the first phone to finish the two-device setup. The GNMN earbuds pair automatically when you take them out of the charging case.
how to charge impact sport headphones
Again I cannot advise on Impact-brand gear. The GNMN earbuds recharge inside their case over USB-C, and the case's dual LED display shows the battery level of both the case and the buds. The BEARTWO Headset charges over its USB connection and takes roughly 3.5 hours for a full charge.
