If you want true wireless earbuds built for gym sweat, long battery life and a secure in-ear fit, choose VIFIGEN Samsung; if you need over-ear, foldable headphones with a headband, a wired backup option and a carrying case, choose Generic B39.
• VIFIGEN Samsung — biggest strength: a genuinely sport-focused design. IPX7 sealing, an in-ear fit that resists slipping, Bluetooth 5.3, active noise cancellation and a charging case that pushes total playback past 60 hours.
• VIFIGEN Samsung — biggest trade-off: it is a true wireless earbud, so there is no headband, no 3.5 mm wired fallback, and all controls live on the buds and case. If you lose one earbud, you are down to mono.
• Generic B39 — biggest strength: an over-ear, foldable headset with 40 mm drivers, a soft cushioned headband, a carrying case and even a 3.5 mm jack for wired listening when the battery runs out.
• Generic B39 — biggest trade-off: three hours of playback per charge is short for long trips, Bluetooth is one generation older, and the noise reduction is passive rather than active.
• Pick VIFIGEN Samsung if you run, lift, commute light, or want earbuds you can forget about for days between charges.
• Pick Generic B39 if you want a traditional headphone shape you fold up and toss in a bag, and you value a wired option.
The VIFIGEN Samsung set is a true wireless earbud built around movement. The headline spec is the IPX7 rating: a sealed housing plus an internal nano-coating that the manufacturer says protects the internals from perspiration and light rain. That is the kind of detail that matters if your earbuds live in a gym bag. The fit is in-ear with silicone tips, and the design brief is clearly about staying put during running and lifting rather than about lounging on a couch.
On the audio side you get 13 mm triple-layer dynamic drivers, which is a large diaphragm for an earbud and usually translates to fuller low end. Bluetooth 5.3 handles the connection, with support for A2DP, HSP, AVRCP and HFP, and the manufacturer claims lower power draw and reduced latency compared with older chips. Range is listed at up to 15 meters in open space. There is active noise cancellation, and controls are a mix of push buttons and touch — notably, volume and track changes sit on physical buttons, which is easier to operate mid-run than a single touch pad that hides every function.
Battery is where this one separates itself. Working time is quoted at over 8 hours per charge, and the 300 mAh case can refill the buds two to three times, for a standby figure over 60 hours. An LED display on the case shows the percentage for each earbud. Charging takes under two hours. There is a magnetic Hall-effect switch, so opening the case auto-pairs to a previously connected phone.
Generic B39: Who It's For
The Generic B39 is the classic over-ear headphone formula, executed as a lightweight foldable. It weighs 7.76 ounces, which is light for an over-ear headset, and the ear cups use soft viscoelastic protein padding that the manufacturer describes as breathable. The headband is adjustable, so fit is not fixed the way an earbud tip is. It folds at multiple points into a small footprint and ships with a carrying case measuring 6.8 x 4.7 x 3.1 inches.
Audio comes from 40 mm dynamic drivers with 105 dB sensitivity, 32 ohm impedance and a 20 Hz frequency response. Those numbers describe an easy-to-drive headphone with a bass-forward tuning — the kind of signature that works well for music, gaming and video calls. Latency is listed at 40 milliseconds, which is fine for casual video but not pitched at competitive gaming. Connectivity is Bluetooth 5.0 with a stated range up to 33 feet, and crucially there is also a 3.5 mm jack, so you can plug in and keep listening once the battery is done. A microphone is built in for hands-free calls, and there is a multi-colour LED light with its own on/off switch.
The weak point is endurance. The spec sheet lists a 3-hour average battery life with a 2-hour charge time, and describes a quick-charge feature that gives you those three hours. For a commute or a work session that is workable; for a long-haul flight it is not. Noise control is passive, meaning the cups physically block some ambient sound rather than cancelling it electronically. The included warranty is three months, which is short.
Who should buy it: commuters who want cups over their ears, students, desk workers on video calls, and anyone who wants a wired option as a safety net. Who should skip it: frequent flyers, marathon listeners, and anyone who needs active noise cancellation or all-day battery.
• Best for workouts and sweat → VIFIGEN Samsung. IPX7 sealing and an in-ear fit designed not to slip.
• Best for battery life → VIFIGEN Samsung. Over 8 hours per charge plus a case that refills the buds 2–3 times, versus 3 hours per charge.
• Best for long trips and flights → VIFIGEN Samsung on endurance alone; Generic B39 only if you accept the short runtime and use the wired jack.
• Best for a traditional over-ear feel → Generic B39. Adjustable headband, cushioned cups, no tips jammed in your ears.
• Best for calls at a desk → Generic B39. The boom-style inline remote and over-ear shape suit sitting at a laptop; the VIFIGEN set is better for calls on the move.
• Best for packing in a bag → Generic B39. It folds into a small footprint and comes with its own case.
• Best for noise reduction → VIFIGEN Samsung. Active noise cancellation beats passive cup sealing on paper.
• Best for connectivity flexibility → Generic B39. Bluetooth plus a 3.5 mm wired jack; the VIFIGEN set is wireless only.
• Best for the latest Bluetooth → VIFIGEN Samsung. Bluetooth 5.3 versus 5.0, with lower claimed latency.
If I were buying one of these for myself, I would take the VIFIGEN Samsung (ASIN B0FFZ454NS). In my opinion, the combination of IPX7 protection, active noise cancellation, Bluetooth 5.3 and a 60-hour-class battery system simply covers more of daily life than a 3-hour over-ear. The Generic B39 is the better pick only if you specifically want over-ear cups, a foldable travel shape and a wired fallback — that is a real preference, not a flaw. Everyone else should start with the VIFIGEN. Check the current price on Amazon before you commit, since that is the one variable that can flip this decision.
Yes, in my view. The VIFIGEN set is IPX7 rated with a nano-coating for sweat and rain, and the in-ear fit is designed to stay put. The B39 is an over-ear headphone with no water-resistance rating listed, so heavy sweat is a risk.
The B39 lists 3 hours of playback per 2-hour charge. The VIFIGEN earbuds list over 8 hours per charge, plus a case that can recharge them 2–3 more times. That is a large gap if you listen all day.
Both connect over Bluetooth to phones, tablets, PCs and laptops. The B39 adds a 3.5 mm jack for wired use; the VIFIGEN set is wireless only, though it lists wide compatibility across iOS 9.0+ and Android 5.0+.
The VIFIGEN Samsung, on paper, because it offers active noise cancellation. The B39 relies on passive noise cancellation, which means the ear cups only physically block some sound. Neither is marketed as a premium travel headphone, so manage expectations.
