How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want marathon battery life in an over-ear pair you can wear all day at a desk or on a plane, choose Picun B8; if you need secure ear-hook earbuds built for running, sweat and rain, choose hadbleng Ear Buds.
• Picun B8 — biggest strength: A massive 120-hour battery rating plus dual 40mm dynamic drivers with three EQ modes (Pop, Bass boost, Rock) for a big, adjustable over-ear sound.
• Picun B8 — biggest trade-off: It's a full over-ear headphone with no water-resistance rating and no active noise cancellation, so it's not the pick for heavy sweating or blocking out a noisy commute.
• hadbleng Ear Buds — biggest strength: Ear-hook earbuds with IPX7 waterproofing, 6g per bud, hybrid ENC call noise cancellation and a 2600mAh charging case that can top up your phone in a pinch.
• hadbleng Ear Buds — biggest trade-off: Earbuds deliver a smaller soundstage than over-ear cups, and the touch controls are Siri-based rather than a full button layout.
• Who each is for: Picun B8 suits commuters, students and home-office users who want long-wear comfort and huge playtime; hadbleng Ear Buds suit runners, gym-goers and anyone who needs buds that stay put through sweat and rain.
The Picun B8 is an over-ear Bluetooth headphone built around one headline number: a 1000mAh battery rated at more than 120 hours of playback per charge. That's the kind of figure that changes how you use a headphone. If you listen roughly four hours a day, you're looking at charging it about once a month rather than once a week. For travel, long study sessions or a full workday of calls and music, that's a genuinely useful design choice rather than a spec-sheet flex.
Sound and comfort are where the over-ear format earns its keep. It uses dual 40mm dynamic drivers with a 20Hz–20,000Hz frequency range, 32 ohm impedance and 42dB sensitivity — easy to drive from a phone or laptop. Three EQ modes let you shift the tuning without opening an app: Pop, Bass boost and Rock, cycled by pressing the EQ button. The earcups are PU leather over elastic sponge, the headband is adjustable, and the earmuffs rotate 60 degrees so they fold flat for packing.
Who should buy it: Anyone who wants one headphone for the whole day — remote workers, students, frequent flyers, movie and game players — and who values not hunting for a charging cable.
Who should skip it: If you run, lift or sweat heavily, this isn't the tool. There's no IP rating, and over-ear cups get hot during hard exercise. It also has no active noise cancellation, so if you need to silence a plane cabin or a busy train, look at an ANC model instead.
hadbleng Ear Buds: Who It's For
The hadbleng Ear Buds (model Q22) are true wireless earbuds with flexible over-ear hooks, and they're clearly designed around movement. Each bud weighs about 6 grams, the hooks hold them in place through running and outdoor work, and IPX7 waterproofing means splashes and rain aren't a problem. Three sizes of silicone ear tips (S/M/L) are included, which matters more than most people admit — a correct seal is what makes an earbud sound good and stay comfortable past the hour mark.
Battery is the other pillar. The buds themselves are rated at 8 hours per charge, and the 2600mAh charging case pushes total playback to around 120–128 hours. A dual LED digital display on the case shows the remaining case power and each bud's charging status, which removes the guesswork of "do I need to plug in tonight?" Type-C charging refills the case in about 2 hours.
Audio and calls lean on a 13mm dual-layer graphene diaphragm driver with bass-enhancement tuning and Hi-Fi processing, plus hybrid ENC noise cancellation on the microphone that claims to cut roughly 90% of background noise on calls. Passive noise cancellation comes from the in-ear seal itself. Bluetooth 5.3 handles the connection with a 15-meter range and one-step auto-pairing once you've paired the first time.
Two details stand out as practical extras. First, the case doubles as an emergency power bank — when fully charged it can push more than 30% into a phone, which is genuinely handy on a long day out. Second, controls are touch-based and Siri-driven, covering track skipping, volume, calls and the voice assistant without reaching for your phone.
Who should skip it: If you want a wide, spacious over-ear soundstage for movies or critical listening, or you prefer physical buttons over touch and voice control, the Q22's earbud format will feel like a compromise.
Side-by-Side: Which Should You Choose?
• Best for all-day battery without recharging → Picun B8. A 120-hour rating on a 1000mAh battery means roughly a month of four-hour days.
• Best for running, gym and rain → hadbleng Ear Buds. IPX7 waterproofing and flexible ear hooks are built for sweat and weather.
• Best for long-wear comfort at a desk → Picun B8. Adjustable headband, 60-degree rotating PU leather cups and a foldable frame.
• Best for phone calls in noisy places → hadbleng Ear Buds. Hybrid ENC mic noise cancellation targets roughly 90% of background sound.
• Best for wired, zero-latency listening → Picun B8. It includes a 3.5mm cable and a low-latency mode for games and video.
• Best for travel and packing → Picun B8. It folds flat and connects to two devices at once via multipoint.
• Best for charging your phone on the go → hadbleng Ear Buds. The 2600mAh case can add more than 30% to a phone in an emergency.
• Best for a compact everyday carry → hadbleng Ear Buds. Buds plus case slip into a pocket; the Picun B8 does not.
In my opinion, the Picun B8 is the better buy for most people. The 120-hour battery, dual 40mm drivers, three EQ modes, multipoint and included 3.5mm cable make it a do-everything headphone for work, study, travel and movies — and the foldable over-ear design is comfortable for long sessions. I'd only steer you to the hadbleng Ear Buds if your priority is movement: running, gym work, outdoor training and rain. There, IPX7 waterproofing, 6g ear-hook buds and an ENC call mic win outright. Pick by how you'll actually wear them, then check the current price on Amazon before you commit.
FAQ
Both are rated around 120 hours of total playback, so it's closer than it looks. The Picun B8 delivers its 120 hours in a single charge; the hadbleng buds give about 8 hours per charge, topped up repeatedly by the 2600mAh case.
Yes. They carry an IPX7 waterproof rating, which covers splashes and rain, and the flexible ear hooks are designed for running and outdoor activity. The Picun B8 has no water-resistance rating, so keep it dry.
No. The Picun B8 lists no noise control, and the hadbleng Ear Buds use passive noise cancellation from the in-ear seal plus ENC on the microphone for calls. Neither actively cancels ambient sound the way an ANC headphone does.
The Picun B8 is the simpler fit here — Bluetooth with a 33-foot range, multipoint for two devices at once, and a 3.5mm cable as a wired fallback. The hadbleng buds connect over Bluetooth 5.3 with a 15-meter range and pair automatically after the first setup.
