How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want one pair of earmuffs that silences a lawnmower while still playing your favorite AM/FM station, choose BJKing 5.4; if you need tiny in-ear buds for the gym, commuting and calls that stay put while you sweat, choose PEFUPEW Earbuds. These two share a Bluetooth version number and almost nothing else — one is hearing protection, the other is an everyday listening tool. Below I break down exactly which one fits your life.
• BJKing 5.4 — biggest strength: It's a proper safety earmuff with an SNR 30dB noise reduction rating, plus a built-in AM/FM radio and Bluetooth 5.4, so you get protection and entertainment in one unit.
• BJKing 5.4 — biggest trade-off: It's bulky over-ear gear at 0.45 kg. You will not toss it in a pocket, and it's overkill if you just want music on the train.
• PEFUPEW Earbuds — biggest strength: A 40-hour total playtime figure, a 400mAh charging case and IP7 waterproofing make it a genuinely practical, lightweight daily driver at just 3 grams per bud.
• PEFUPEW Earbuds — biggest trade-off: ENC noise reduction here is about cleaning up your voice on calls — it filters background noise around your microphone. It does not protect your hearing from loud machinery.
• Who each pick is for: Choose BJKing 5.4 if your day involves mowing, snowblowing, woodworking or a loud workshop. Choose PEFUPEW Earbuds if your day involves running, the gym, commuting and phone calls.
The BJKing 5.4 is, first and foremost, ear protection. That's the whole point of it. The SNR 30dB rating is the headline number, and it's certified to ANSI S3.19 and CE EN352-1 — the standards that actually matter for this category. Everything else is built around that job.
What makes it unusual is the radio. You get a digital AM/FM tuner with an LCD screen showing frequency, Bluetooth status and battery, plus memory for up to 20 AM and 20 FM stations. There's manual tuning and auto-scanning, so you can find and save stations without fiddling. An AUX input jack and included cable let you plug in other audio devices too. For anyone who spends hours on a riding mower or behind a snowblower, that's a real quality-of-life feature — the task stops being silent boredom.
Comfort is handled with a flexible adjustable headband and gel ear pads in yellow, sized large, with soft foam cups that mold around your ears. It fits adult head sizes, and the padded headband is described as wider and thicker than typical. It ships with a cable and a user manual, is imported, and carries a 2-year manufacturer warranty.
PEFUPEW Earbuds: Who It's For
The PEFUPEW Earbuds are the opposite philosophy: disappear into your ears and stay out of the way. Each bud weighs about 3 grams, uses an in-ear design meant to reduce ear canal pressure, and comes with soft silicone tips that resist slipping. In black, with a modern in-ear shape and touch controls.
The audio hardware is a 14.2mm dynamic driver with 32-ohm impedance — a large driver for earbuds, which usually translates to stronger bass and fuller vocal presence. Bluetooth 5.4 handles the connection with a stated 15-meter range, and magnetic Hall-effect tech means the buds auto-connect the moment you lift them out of the case after the first pairing.
Battery is where these shine. You get roughly 8 hours per charge, a 1.5-hour charge time, and a 400mAh charging case that pushes total playtime to around 40 hours. A dual LED display shows battery percentage from 0 to 100, so you're never guessing. IP7 waterproofing with nano-coating handles sweat and rain, which is what makes them credible for cycling, hiking and training.
Call quality comes from ENC noise reduction, which filters a large share of background noise around your voice so you're clearer in coffee shops, on commutes or at work. Touch controls manage music, calls and voice assistants, and they pair with iOS, Android, laptops and tablets.
Who should buy it: runners, gym-goers, commuters, cyclists, travelers and anyone who takes a lot of calls. Who should skip it: anyone who needs genuine hearing protection around loud equipment. ENC is a microphone feature, not a safety rating — don't confuse the two.
• Best for hearing protection → BJKing 5.4. SNR 30dB, certified to ANSI S3.19 and CE EN352-1. The PEFUPEW Earbuds have no noise reduction rating for your ears at all.
• Best for listening during loud chores → BJKing 5.4. Built-in AM/FM radio with 20 AM and 20 FM presets, LCD display and AUX-in. The PEFUPEW Earbuds have no radio.
• Best for battery life → PEFUPEW Earbuds. Around 40 hours total with the case versus a single-charge earmuff design.
• Best for workouts and sweat → PEFUPEW Earbuds. IP7 waterproof nano-coating and 3-gram buds. The BJKing is over-ear workshop gear.
• Best for calls → PEFUPEW Earbuds. ENC noise reduction aimed at your voice, with touch controls for answering.
• Best for bass and music depth → PEFUPEW Earbuds. A 14.2mm dynamic driver at 32 ohms is built for punchy low end.
• Best for all-day comfort on a job site → BJKing 5.4. Adjustable padded headband and gel ear pads designed for long wear under a hat or alone.
• Best for portability → PEFUPEW Earbuds. A pocketable case versus 0.45 kg of earmuff.
If your priority is protecting your ears, the BJKing is the only one of the two that does that job. If your priority is music, calls and movement, the PEFUPEW wins outright.
In my opinion, these aren't really competitors — they solve different problems, and the "better" one depends entirely on the noise you're standing in. If I had to buy one for a life that includes a lawn, a workshop or a snowblower, I'd take the BJKing 5.4: the SNR 30dB rating, the AM/FM tuner and the 2-year warranty make it a purpose-built tool, and nothing about the PEFUPEW replaces it. If I wanted earbuds for running, commuting and calls, I'd take the PEFUPEW Earbuds without hesitating — 40 hours of playtime, IP7 sweat resistance and a 14.2mm driver is a strong daily package. Buy for the job you actually have.
The BJKing 5.4, clearly. It's an earmuff with an SNR 30dB noise reduction rating certified to ANSI S3.19 and CE EN352-1, and it has a built-in AM/FM radio so you're not mowing in silence. The PEFUPEW Earbuds reduce background noise around your microphone for calls — they don't protect your hearing.
The spec sheet says about 8 hours of playback per charge, with the 400mAh case extending total playtime to roughly 40 hours. Charging takes about 1.5 hours, and the dual LED display shows battery percentage so you can track it.
Yes. It uses Bluetooth 5.4 for calls and music, with an LCD screen showing connection and battery status, plus an AUX input for wired audio. It's just not a hands-free, in-ear calling device the way the PEFUPEW buds are.
If you're in loud environments, the BJKing 5.4 is the one that does both — protection plus radio and Bluetooth audio. If your environments are quiet and you mainly want music and calls, the PEFUPEW Earbuds are the more comfortable, portable choice.
