How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a gaming-first pair of in-ear buds with a dedicated low-latency mode, choose Black Shark Gaming Earbuds; if you need marathon battery life and a hook design that stays put through hard workouts, choose PEFUPEW Earbuds. That's the short version. The longer version comes down to what you actually do with earbuds all day — sit at a screen chasing audio sync, or sweat through runs and gym sessions while your case quietly keeps recharging.
• Black Shark Gaming Earbuds — biggest strength: A dedicated Gaming Mode with a 35ms ultra-low latency figure for competitive play, plus 10mm dynamic drivers and four microphones tuned for clear team chat.
• Black Shark Gaming Earbuds — biggest trade-off: Battery is the weak point. About 5 hours per charge and roughly 20 hours total with the case, so heavy users will recharge most days.
• PEFUPEW Earbuds — biggest strength: Endurance and fit. Up to 48 hours of total playback, up to 8 hours per charge, IP7 waterproofing, and flexible ear hooks that resist falling out.
• PEFUPEW Earbuds — biggest trade-off: The over-ear hook shape is bulkier and more conspicuous than a slim in-ear bud, and it's built around sport rather than gaming sync.
• Who Black Shark is for: Gamers and call-heavy users who want touch controls, a compact charging case, and a low-latency mode.
• Who PEFUPEW is for: Runners, gym-goers, and anyone who hates charging — especially people who wear earbuds for hours at a time.
The Black Shark Gaming Earbuds (model T2, sometimes sold under the Lucifer T2 name) are built around one clear idea: make Bluetooth audio feel less laggy when you're playing. There's a Gaming Mode that the brand ties to a 35ms ultra-low latency figure, and a Music Mode that leans on 10mm high-sensitivity dynamic drivers with a 20Hz–20,000Hz frequency range. In practice that means you get two personalities from one pair — a tighter, more reactive mode for games, and a fuller mode for music and video. Whether the difference is night-and-day depends on your ears and your games, but the intent behind the design is obvious.
Battery is where you need to be honest with yourself. You get up to 5 hours on a single charge, and the charging case adds up to 15 more hours, for roughly 20 hours total. The case and buds each take about 1.5 hours to charge. For a desk gamer who plays a few hours a night and drops them on a charger, that's fine. For someone who wants to leave the case at home and forget about charging for a week, it isn't.
Buy Black Shark if you game on a phone or tablet, take a lot of calls, and want a compact in-ear bud with a gaming mode and swappable ear tips for a secure fit. Skip it if you need all-day or multi-day battery, or if you want active noise cancellation rather than isolation.
PEFUPEW Earbuds: Who It's For
The PEFUPEW Earbuds (model C6) take the opposite approach. Instead of chasing the lowest latency number, they chase staying power and staying on your head. The headline is battery: up to 48 hours total playback, with up to 8 hours per charge at 50% volume, and a case that provides 4–5 additional charges. Charging is USB-C and takes about 1.5 hours, and the case has a dual LED display so you can see where things stand without guessing.
The fit is the other half of the story. These are over-ear buds with flexible ear hooks, and the brand frames that design as reducing ear canal pressure for long wear while keeping the buds locked in during intense exercise. Water resistance is rated IP7 — a step above the Black Shark's IPX5 — so sweat, rain, and heavy gym sessions are squarely in scope. The driver is a large 14.2mm dynamic driver with a three-layer composite diaphragm, paired with four ENC microphones the brand says cut around 80% of background noise for calls. Impedance is 32 ohm.
On the tech side you get Bluetooth 5.4 with a 15-meter range and a stated audio delay of 40 milliseconds, plus touch controls. Noise control is passive noise cancellation and sound isolation — no active ANC here either. The enclosure is ABS, the color is J-Blue, and the set ships with the case, silicone earplugs in S/M/L, a USB-C cable, and a manual. Item weight is listed at 58g, which is mostly the case and hooks — these are not featherweight, hidden buds.
Side-by-Side: Which Should You Choose?
• Best for competitive gaming → Black Shark Gaming Earbuds. The dedicated Gaming Mode and 35ms latency figure are the whole point of this pair.
• Best for battery life → PEFUPEW Earbuds. Up to 48 hours total and up to 8 hours per charge versus roughly 20 hours total on the Black Shark.
• Best for workouts and running → PEFUPEW Earbuds. IP7 waterproofing plus flexible ear hooks designed to stay put during intense exercise.
• Best for discreet, everyday in-ear wear → Black Shark Gaming Earbuds. Rounded-tip in-ear design with multiple ear tip sizes and no hooks.
• Best for calls in noisy places → PEFUPEW Earbuds. Four ENC microphones with a stated 80% background-noise reduction.
• Best for low-latency feel across games and video → Black Shark Gaming Earbuds. The 35ms gaming figure edges the PEFUPEW's 40ms on paper, though both are in the same ballpark.
• Best for newer Bluetooth and longer range → PEFUPEW Earbuds. Bluetooth 5.4 and a 15-meter range beat Bluetooth 5.2 at 10 meters.
• Best for a compact, pocketable case → Black Shark Gaming Earbuds. A standard charging case versus PEFUPEW's larger hook-and-case setup.
If I had to pick one for myself, I'd take the PEFUPEW Earbuds. In my opinion, the 48-hour battery, IP7 rating, and hook-based fit solve the problems most people actually run into day to day — forgetting to charge and buds working loose. The Black Shark pair is the smarter buy only if gaming sync and a slim in-ear shape are your priorities, and even then the 20-hour total battery means you'll be reaching for the charger often. Both are Bluetooth-only, both use passive isolation rather than ANC, and both are built for adults. Check the current price on Amazon before you commit, since that's the one thing specs alone can't tell you.
Not really. You get up to 5 hours per charge and about 20 hours total with the case, so most people will charge daily. It's fine for evenings and commutes, tight for all-day wear.
Yes — that's their design focus. IP7 waterproofing, flexible ear hooks, and up to 8 hours per charge at 50% volume make them well suited to running, gym sessions, and long training blocks.
The PEFUPEW Earbuds list four ENC microphones with a stated 80% background-noise reduction, which is the more call-focused setup on paper. The Black Shark pair counters with two mics per bud for voice pickup. Neither offers active noise cancellation.
The brand rates its Gaming Mode at 35ms ultra-low latency, and the PEFUPEW sits at 40ms. Both are designed to feel responsive; the Black Shark's dedicated gaming mode makes it the more purpose-built option for competitive play.
