How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want the longer total battery life, a tougher waterproof rating and a wider Bluetooth range, choose PWTEK Earbuds; if you need more playtime from a single charge and a newer Bluetooth generation, choose Keenso 5.4.
• PWTEK Earbuds — biggest strength: IPX7 waterproofing plus a 48-hour total battery figure and 12 m Bluetooth range, backed by a 1-year warranty. Biggest trade-off: only 6 hours per earbud, and it runs the older Bluetooth 5.3.
• Keenso 5.4 — biggest strength: 7 hours of playtime per charge and Bluetooth 5.4, the newer wireless generation of the two. Biggest trade-off: a shorter 10 m range, a 90-day warranty, and no water-resistance rating published in the specs.
• Pick PWTEK Earbuds if you sweat heavily, run outdoors in the rain, or want the longer combined battery and the longer warranty.
• Pick Keenso 5.4 if your priority is squeezing more time out of a single charge and you want the newer Bluetooth version.
• Rough tie-breaker: both are in-ear, both have an LED battery display on the case, both use touch controls, and both top out at 42–48 hours with the case. The decision comes down to water resistance and range versus per-charge runtime and Bluetooth generation.
The PWTEK Earbuds are built around one clear idea: survive real movement. The IPX7 rating is the headline spec here — that's the level of protection that covers sweat, rain and even accidental immersion, which is exactly the scenario a runner or gym-goer runs into. If you've ever killed a cheap pair of buds with a sweaty T-shirt or a sudden downpour, that single number is the reason to look at this model.
The rest of the spec sheet supports the same story. Each earbud weighs 3.6 g, so they're light enough to forget about during a long session, and PWTEK includes three silicone tip sizes (S/M/L) so you can actually dial in a fit that stays put. The 13 mm dynamic drivers are the largest figure in this comparison, and the frequency range is listed at 20 Hz–20,000 Hz — a full-range claim that points to a bass-forward tuning rather than a thin, tinny one. Bluetooth 5.3 gives you a 12 m working range, which is the more generous of the two here, and the case adds an LED display so you can see charge levels instead of guessing.
Buy it if you want water resistance, a longer combined battery, a wider Bluetooth range, and a full-year warranty. Skip it if you rarely get wet, want the newest Bluetooth generation, or care most about how long the buds run before they need the case.
Keenso 5.4: Who It's For
The Keenso 5.4 plays a different hand. Its strongest card is the 7 hours of playtime on a single charge — the highest per-bud figure in this comparison — extended to 42 hours with the charging case. If your routine is long and you hate docking the buds mid-session, that extra hour per charge matters more than it sounds, especially on back-to-back days where you forget to top up the case.
It also runs Bluetooth 5.4, the newer generation of the two, which the listing pairs with a 10 m range and low-latency wireless audio. In practice that's a clean, cable-free connection for running, lifting or taking calls, with the same touch controls as the PWTEK for playback, volume and calls. The case carries an LED display showing remaining battery and charging status, and the ergonomic in-ear shape is designed around comfort during activity.
Where the Keenso gives ground is durability documentation. The listed specs describe the earbuds as in-ear and black, with a comfortable fit for long listening, but there's no IP rating published — so I can't tell you it shrugs off sweat or rain the way the PWTEK's IPX7 does. Its warranty is 90 days versus PWTEK's 1 year, and the connectivity field in the product data oddly reads "ethernet," which I'd disregard entirely; the actual product is a Bluetooth in-ear set, as the description makes clear. One more spec quirk: the Keenso listing doesn't publish a driver size, so there's no way to compare driver hardware fairly — the sound claim rests on "powerful bass and clear stereo sound" rather than a number.
Buy it if you want the most playtime per charge, the newer Bluetooth version, and a light in-ear set for running and workouts. Skip it if you train hard enough to soak your gear, want a documented water-resistance rating, or prefer the longer warranty.
• Best for water resistance and rain → PWTEK Earbuds. IPX7 against no published rating is not close.
• Best for battery life per charge → Keenso 5.4. 7 hours versus 6.
• Best for total battery with the case → PWTEK Earbuds. 48 hours versus 42.
• Best for connection range → PWTEK Earbuds. 12 m versus 10 m.
• Best for the newest Bluetooth generation → Keenso 5.4. 5.4 versus 5.3.
• Best for warranty coverage → PWTEK Earbuds. 1 year versus 90 days.
• Best for bigger drivers on paper → PWTEK Earbuds. 13 mm dynamic drivers; Keenso doesn't publish a figure.
• Best for heavy sweating, swimming-adjacent or outdoor training → PWTEK Earbuds.
• Best for long sessions where you charge infrequently → Keenso 5.4.
I'd buy the PWTEK Earbuds. In my opinion, the IPX7 rating, the 48-hour total figure, the 12 m range and the 1-year warranty add up to the more forgiving package for everyday abuse — and water damage is the most common way cheap earbuds die. The Keenso 5.4 is a legitimate pick if the newer Bluetooth generation and that extra hour per charge are what you care about, and it's the one I'd hand to someone who mostly trains indoors. But if you want one pair to cover sweat, rain and long weeks without babysitting the case, PWTEK is the safer call. Check the current price on Amazon before you decide, since that's the one thing that can flip this either way.
PWTEK. It carries an IPX7 water-resistance rating, which covers sweat and rain. Keenso's specs don't publish any IP rating, so there's no documented protection to rely on.
It depends on how you count. Keenso gives 7 hours per charge versus PWTEK's 6. Over a full case cycle, PWTEK wins at 48 hours total against Keenso's 42.
Keenso uses Bluetooth 5.4, one generation newer than PWTEK's 5.3. PWTEK counters with a longer 12 m range versus Keenso's 10 m, so the newer version doesn't automatically mean better range.
Neither listing publishes a price here, so check the current price on Amazon for both. On specs alone, PWTEK gives you water resistance, more total battery and a 1-year warranty; Keenso gives you longer per-charge runtime and Bluetooth 5.4.
