How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a wired, sweat-proof sport earbud that simply plugs in and never needs charging, choose JVC Black; if you need wireless freedom, long battery life and a secure ear-hook fit for hard workouts, choose Matast Earbuds.
• JVC Black — biggest strength: A true wired 3.5 mm connection with a sweat- and splash-proof build and "Nozzle Fit" earpieces plus extra nozzle sizes for a locked-in, customizable fit.
• JVC Black — biggest trade-off: No battery, no Bluetooth, no noise cancelling and no microphone array beyond the inline 1-button remote — it only works with devices that still have a headphone jack.
• Matast Earbuds — biggest strength: Bluetooth 5.4 wireless with up to 75 hours of total playtime from the charging case, IP7 waterproofing and flexible ear hooks that hold during running and gym work.
• Matast Earbuds — biggest trade-off: It's a rechargeable, case-dependent system — you have to manage charging and pairing, and there's no wired fallback if the battery runs dry.
• Who JVC Black is for: Runners, gym-goers and commuters who want zero fuss, zero charging and a rock-solid wired connection.
• Who Matast Earbuds is for: Anyone who wants untethered movement, long listening sessions and hands-free calling during sweaty training.
The JVC Black is the no-nonsense option. It's a wired in-ear sport earbud with a 3.5 mm stereo jack, a 3.3-foot color-matched cord, and a "Nozzle Fit" earpiece design that JVC built specifically to stay put while you move. The sweat- and splash-proof construction is aimed at exactly the kind of abuse a workout throws at cheap earbuds — moisture, heat and constant jostling. And because two sizes of nozzles are included, you can actually dial in the seal and comfort instead of accepting whatever tip ships in the box.
It also keeps things refreshingly simple. There's a 1-button inline remote and mic, so you can take a call or pause a track without digging out your phone. The dynamic driver covers a 20 Hz – 20,000 Hz range, which is the standard full-range window you'd expect for everyday music and podcasts. It's a plastic-bodied, adult-sized, in-ear set — light at 4.8 grams, backed by a one-year parts and labor warranty.
Matast Earbuds: Who It's For
The Matast Earbuds are the modern, feature-packed counterpoint. These are true wireless sport earbuds with Bluetooth 5.4, and Matast claims that versus Bluetooth 5.3 the data transmission is twice as fast with 30% lower power consumption, plus a connection range up to 15 meters. In practical terms, that means you can leave your phone on a bench or in a bag and keep moving without the music cutting out. They pair with iOS, Android, tablets and laptops, and they support the standard HFP, HSP, A2DP and AVRCP profiles.
The fit story is the standout for sports. These are over-ear, hook-style buds — the earpiece shape is a hook, and the flexible ear hooks are designed to keep the buds snug through vigorous exercise. Three sizes of ear caps are included, so you can tune the seal. The IP7 nano-coating handles sweat, splashes and rain, which is exactly what you want for running and gym sessions.
Audio and battery are where it pulls ahead on paper. A 13 mm dynamic driver is a large speaker for earbuds, and Matast says it delivers powerful bass, a mellow midrange and clear treble. There are four ENC noise-cancelling mics that Matast claims passively cancel 80% of background noise, so your voice comes through on calls even in a noisy gym. Noise control here is sound isolation rather than active cancellation. Battery life is up to 10 hours on a single charge, extending to 75 hours with the charging case, and a full charge takes about 1.5 hours over Type-C. A dual LED display shows the case's remaining power and the buds' charging progress. Controls are touch-based — play, pause, answer, reject, skip tracks and wake Siri — and after the first connection the buds auto-connect when you open the case.
Buy Matast Earbuds if you want wireless freedom, long battery life, hands-free calling and a hook fit built for hard training. Skip them if you'd rather not deal with charging a case, or you specifically want a wired connection that never runs out. My take: this is the pair for the runner who wants their earbuds to keep up with a full week of sessions without a recharge.
• Best for battery life → Matast Earbuds. Up to 10 hours per charge and 75 hours total with the case dwarfs a wired set that has no battery at all.
• Best for zero-maintenance simplicity → JVC Black. No charging, no pairing, no case — plug in and go.
• Best for secure fit during hard workouts → Matast Earbuds. Flexible ear hooks plus three ear-cap sizes are purpose-built to stop slippage.
• Best for sweat and rain resistance → Matast Earbuds. IP7 waterproofing is a stronger, more explicit rating than JVC's sweat- and splash-proof claim.
• Best for calls and hands-free control → Matast Earbuds. Four ENC mics and touch controls beat a single inline button.
• Best for older phones, laptops and audio players → JVC Black. The 3.5 mm jack works with anything that has a headphone port — no Bluetooth required.
• Best for wired reliability and no signal dropouts → JVC Black. A physical cable can't lose its connection mid-run.
• Best for a customizable in-ear seal → tie. Both include extra nozzle or ear-cap sizes so you can dial in fit.
If I'm choosing for a typical 2026 buyer who runs, lifts or trains regularly, I'd buy the Matast Earbuds. The combination of Bluetooth 5.4 wireless freedom, IP7 waterproofing, ear-hook security, 75 hours of total playtime and four-mic call clarity is simply a better match for how most people train today — no cable snagging on equipment, no phone in your pocket. That said, the JVC Black is the smarter call if you want a wired, charge-free backup you can leave in a gym bag and never think about. In my opinion, pick Matast for the main pair and JVC if simplicity and a headphone jack matter more to you than wireless convenience. Check the current price on Amazon before you commit.
how to wear sports earbuds
For the Matast Earbuds, loop the flexible ear hook over the top of your ear and seat the bud in your ear canal, then try the three included ear-cap sizes until the seal feels snug but not painful. For the JVC Black, push the Nozzle Fit earpiece into place and swap to the alternate nozzle size if the fit feels loose. A correct seal is what keeps either pair from slipping during a run.
how to pair bose sports earbuds
That question is about Bose, not these two models, so here's how pairing works on the Matast Earbuds instead: open the charging case and they auto-connect to your device after the first setup. The JVC Black doesn't pair at all — it's wired, so you just plug the 3.5 mm jack into your device.
how to reset bose sports earbuds
These aren't Bose earbuds, so a Bose reset won't apply. For the Matast Earbuds, the practical fix for connection trouble is to remove the buds from your phone's Bluetooth list and re-pair them from the case. The JVC Black has no firmware or pairing to reset — if there's no sound, check that the jack is fully seated.
how to connect bose sports earbuds
Again, that's a Bose-specific query. For Matast, connection is automatic once paired: open the case and the buds link to your device, with a Bluetooth range up to 15 meters. The JVC Black "connects" by plugging its 3.5 mm stereo jack into any compatible headphone port.
