How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a pair of sport earbuds built around long battery life, a secure over-ear hook fit and serious sweat resistance, choose PEFUPEW Earbuds; if you need active noise cancellation, a control case with a touchscreen and on-the-fly EQ switching, choose jaddsa Earbuds.
• PEFUPEW Earbuds biggest strength: Up to 48 hours of total playback (8 hours per charge from the buds themselves), IP7 water resistance and a flexible ear-hook design that stays put during hard training.
• PEFUPEW Earbuds biggest trade-off: Noise control is passive only — it relies on sound isolation rather than active cancellation, so loud gym music or traffic noise gets through.
• jaddsa Earbuds biggest strength: Active Noise Cancellation plus a multifunction touchscreen charging case that lets you change tracks, volume, EQ modes and locate the buds without touching your phone.
• jaddsa Earbuds biggest trade-off: The data sheet doesn't list an IP rating or total battery figure, so endurance and sweat resistance are less clearly spelled out than on the PEFUPEW.
• Pick PEFUPEW Earbuds if you want a marathon-session pair for running, workouts and rainy outdoor training.
• Pick jaddsa Earbuds if you want quieter focus, more control from the case itself, and the freedom to tune the sound to whatever you're playing.
The PEFUPEW Earbuds are built around one clear idea: keep the music going, whatever you're doing. The headline number is 48 hours of total playback, with each bud rated at up to 8 hours on a single charge at 50% volume, and the charging case said to provide 4–5 extra top-ups. That's the kind of figure that matters if you're the person who forgets to charge things — a couple of long runs and a week of commutes won't wipe them out. Charging is over USB-C and takes about 1.5 hours, and the case has a dual LED display so you can see where the battery stands.
Under the hood there's a 14.2mm dynamic driver with a three-layer composite diaphragm, and PEFUPEW claims the bass is boosted by 43% with a frequency range of 20 Hz–20,000 Hz. Take those numbers as manufacturer claims rather than independent measurements, but the driver size and impedance (32 ohm) tell you this is a listenable, bass-forward tuning aimed at pop, hip-hop and workout playlists rather than critical listening. Calls get four ENC microphones, which PEFUPEW says cut around 80% of background noise — useful on a noisy street or in a busy office. Connectivity is Bluetooth 5.4 with a claimed 15-metre range and a low-latency design, and the touch controls are described as 22.5% more accurate than the previous generation, which is the sort of spec that usually translates to fewer accidental skip-tracks mid-run.
jaddsa Earbuds: Who It's For
The jaddsa Earbuds take a completely different approach: instead of maximising endurance, they put the controls in your hand — or rather, in the case. The standout feature is the multifunction touchscreen charging case. From that little screen you can switch songs, adjust volume, jump between 5 EQ modes, locate a missing earbud, or take a call. That's genuinely unusual in the sport-earbud category, and it solves a real annoyance: digging your phone out of an armband or a zipped pocket mid-workout. If you've ever fumbled with your phone in the middle of a set, the appeal here is obvious.
Sound-wise, jaddsa uses 12mm dynamic drivers and quotes bass response down to 40 Hz, with Rock, Hip-hop and Pop presets you can switch instantly. The pitch is that you match the EQ to the intensity of what you're doing — a heavier preset for lifting, something brighter for a steady run. That's a fun, tactile way to interact with your music, though it's worth being realistic: EQ presets change the flavour of the sound, not the fundamental character of the drivers. A 12mm driver is a touch smaller than the PEFUPEW's 14.2mm unit, which in general terms means slightly less physical punch — but tuning matters more than size on its own, so I wouldn't read too much into it.
The other defining feature is Active Noise Cancellation. Unlike passive isolation, ANC actively reduces steady background noise — the drone of a treadmill, a fan, traffic rumble — which makes it the better pick for focus, commuting or a crowded gym. On top of that you get Bluetooth 5.4 and touch controls on the buds themselves, so you're not dependent on the case for everything.
Side-by-Side: Which Should You Choose?
• Best for battery life → PEFUPEW Earbuds. Up to 48 hours total, 8 hours per charge, plus 4–5 case top-ups.
• Best for noise reduction → jaddsa Earbuds. Active Noise Cancellation beats passive isolation for steady background noise.
• Best for sweat and rain → PEFUPEW Earbuds. A stated IP7 rating makes it the safer bet for outdoor sessions.
• Best for hands-on control → jaddsa Earbuds. The touchscreen case handles volume, tracks, EQ and earbud locating without your phone.
• Best for sound tweaking → jaddsa Earbuds. 5 EQ presets let you reshape the tuning on the fly.
• Best for a secure, locked-in fit → PEFUPEW Earbuds. Flexible ear hooks are designed not to shift during intense exercise.
• Best for call clarity in noise → PEFUPEW Earbuds. Four ENC microphones are specified for cutting background noise on calls.
• Best for commuting and focus → jaddsa Earbuds. ANC is the feature that matters most when you're trying to tune the world out.
If I were buying one pair for myself and my priority was training hard without babysitting a charger, I'd buy the PEFUPEW Earbuds. The combination of a documented 48-hour total runtime, IP7 water resistance and ear hooks designed to stay put is exactly what a runner or gym-goer needs, and the 14.2mm driver gives it the bigger low-end hardware on paper. That said, if you commute, work in a noisy space, or simply love the idea of controlling everything from a touchscreen case, the jaddsa Earbuds are the more interesting product — ANC and the smart case are features the PEFUPEW simply doesn't offer. Match the pick to your environment, not to a spec sheet. And since neither manufacturer's pricing is listed here, check the current price on Amazon before you commit.
FAQ
jaddsa. Its data sheet lists Active Noise Cancellation, which actively reduces steady background sound. PEFUPEW relies on passive noise cancellation and sound isolation, which only blocks noise by sealing your ear.
Rain and sweat, yes — IP7 water resistance covers sports, workouts and wet weather. Swimming, no. The manufacturer states they aren't suitable for use in water and are intended for sports activities rather than underwater use.
The jaddsa data sheet doesn't list a total playback time, a per-charge figure or a charging time, so there's no direct comparison available. PEFUPEW specifies 48 hours total, 8 hours per charge and 1.5 hours to charge.
In my opinion, PEFUPEW edges it for pure training: the ear hooks are designed for intense exercise and the IP7 rating handles sweat. jaddsa is the better gym pick if the room is loud and you want ANC, or if you'd rather change tracks from the case than your phone.
