If you’re hunting for an ultra-long battery wireless headset that won’t shred your budget, this Picun B8 Bluetooth Headphones review is for you. We stress-tested the B8’s claimed 120-hour playtime, cycled through its 3 EQ modes, and made daily calls to judge its low-latency performance across phones, laptops, and tablets. The headline: it’s shockingly capable for travel, WFH, and study sessions.
Below you’ll find deep dives on battery endurance, comfort, sound tuning, and how the B8 stacks up to other trending budget favorites. If you’re deciding today, here’s the fast track:
Product Overview
The Picun B8 Bluetooth Headphones target the sweet spot for commuters, students, and remote workers: big battery, comfy pads, simple controls, and useful EQ presets for quick tuning.

If your priority is all-day (and multi-day) listening with minimal charging, this is the lane.

Pros & Cons
What We Liked
- unbelievable endurance: truly multi-day playback on a single charge.
- Instant EQ toggles for genre-hopping without digging into an app.
- Low-latency mode that makes video sessions feel natural.
- Comfortable fit for study, work, and travel.
- Great value if ANC isn’t your priority.
Room for Improvement
- No active noise cancelling (relies on passive isolation).
- Plastic build is durable but not premium metal.
- Call mics are fine indoors; windy outdoor calls still challenge most budget sets.
Performance Tests & Real-Life Use
We wore the Picun B8 across a full workweek, including commuting, Zoom calls, and after-hours streaming. Here’s how it behaved in the places you’ll actually use it:
- Office / WFH: Solid passive isolation softens HVAC and chatter, while Vocal EQ keeps voices crisp for podcasts and meetings.
- Commute: Engines and train noise are reduced by the physical seal; for loud rumbles, modest volume boosts do the trick.
- Streaming: Low-latency profile noticeably improves lip-sync on Netflix/YouTube compared to default Bluetooth.
- Gaming (casual): The low-latency mode helps, but competitive FPS players should still prefer wired options; for casual sessions, it’s perfectly enjoyable.
Our biggest takeaway? The battery changes behavior. You stop rationing listening time or hunting chargers, and that freedom is addicting.
Sound Quality & EQ Modes
The B8 leans slightly lively and consumer-friendly. Out of the box, you’ll hear a gentle bass lift with smooth highs; flipping EQ modes reshapes the signature fast:
- Bass Mode: Adds sub-bass weight for EDM/hip-hop. Great fun, but switch to Balanced if mids feel recessed.
- Balanced Mode: Our default for playlists — keeps low-end punch without smearing vocals.
- Vocal/Podcast Mode: Lifts the mids/upper-mids so voices cut through background noise.
Compared with wired classics like Panasonic RP-HT161 (see our review), the B8 trades ultimate raw detail for freedom: Bluetooth convenience, EQ agility, and that monster battery.
Battery & Charging
120 hours is the flagship claim, and while real-world numbers always depend on volume and mode, we blasted through workdays without touching a cable. Even after movie nights and calls, the percentage barely moved. Quick top-ups via USB-C erase “battery anxiety,” which is the B8’s superpower.
- Realistic Expectation: 90–120 hours at moderate volumes in Balanced/Vocal modes; Bass mode shaves a bit off.
- Charging TLC: For long-term health, keep the cell between roughly 20–90% when possible.
Call Quality & Low Latency
Indoors, voices are clear and intelligible. In busy streets, the mics still focus your speech but (like most budget headsets) can’t fully erase wind gusts. For streaming, the low-latency profile cuts the delay enough that dialog and on-screen motion feel natural to non-gamers.

Comfort, Fit & Build Quality
The B8 is lightweight with ample padding. Clamp force is moderate — snug enough for walking and desk nods, relaxed enough for three-hour study blocks. The plastics are sturdy for the price, and the fold-flat hinges haven’t shown creaks in our sample.
- Glasses-friendly: Pads are forgiving; small hinge rotations help relieve temple pressure.
- Heat: Like all closed-back over-ears, expect warm ears in summer. Take a few air breaks on long sessions.
- Finish: Khaki White looks clean and modern; darker finishes hide scuffs better.
Connectivity & Pairing
Pairing is quick on Android, iOS, and laptops. The B8 keeps a stable link in typical apartments and offices. It remembers multiple devices so you can swap from phone to laptop with a couple of taps — exactly what we want for WFH workflows.
- Range: Around 10 m / 33 ft line-of-sight; walls reduce range as usual.
- Multipoint-style use: While not formal multipoint on every unit, the B8 flips devices fast enough that it feels seamless in practice.
- Controls: Reliable tactile buttons (play/pause, volume, calls, EQ).

Who Should (and Shouldn’t) Buy the Picun B8
Perfect For
- Students who want week-long charge and quick EQ for classes vs. music.
- WFH pros who bounce between calls and playlists without babysitting battery.
- Travelers who prefer light, foldable, reliable over-ears.
Maybe Skip If You Need
- Top-tier ANC for airplanes (consider Soundcore Q20i/Q30 or premium Bose/Sony).
- Premium metal build (you’ll pay more and lose some battery life).
Setup, App & Pro Tips
- Pairing: Hold power to enter pairing, then pick “Picun B8” in Bluetooth settings.
- EQ Toggle: Tap the EQ button to cycle Bass → Balanced → Vocal. Use Vocal for meetings.
- Low-Latency Mode: Switch it on before Netflix/YouTube for better lipsync; turn off for music to save battery.
- Seal Matters: Reposition cups to improve bass and isolation (especially with glasses).
- Battery Health: Avoid running 0→100% constantly. Top up during coffee breaks.
Troubleshooting & Care
- Dropouts: Forget & re-pair the headset; keep phone away from metal cabinets and crowded 2.4 GHz routers.
- Mic Too Quiet: Speak slightly closer; shield from wind when outside.
- Weak Bass: Improve the seal and check you’re in Bass or Balanced EQ.
- Pad Care: Wipe with a slightly damp microfiber after workouts; air dry.
People Also Ask
Is the Picun B8 good for calls?
Yes — it’s clear indoors and fine in moderate street noise. For windy days, cup a hand near the mic or step inside for best results.
Does Picun B8 have ANC?
No. It relies on passive isolation. If you want active noise cancelling, consider Soundcore Q20i in the same price neighborhood.
How long does the battery actually last?
Our mixed-use testing suggests 90–120 hours depending on volume, EQ mode, and low-latency usage. It’s genuinely multi-day.
Is the Picun B8 comfortable with glasses?
Yes. The pads are soft and the clamp is moderate; minor earcup rotation helps avoid temple pressure.
What’s the difference between Bass, Balanced, and Vocal EQ?
Bass lifts sub-bass for EDM/hip-hop, Balanced keeps genres versatile, and Vocal elevates mids for podcasts, YouTube, and calls.
Buying Guide (2025): How to Choose Budget Wireless Over-Ears
- Battery First: If you hate charging, prioritize 60h+ models. The B8’s 120h is category-leading.
- EQ Access: On-device presets matter more than fancy apps if you need quick switches.
- Isolation vs. ANC: Passive isolation works well for office/commute; ANC costs more and reduces battery life.
- Comfort: Under 300 g with plush pads is ideal for long sessions.
- Latency: A low-latency profile improves streaming; gamers still prefer wired for eSports.
- Build: Plastics are fine for weight/battery; look for clean hinge action and minimal creaks.
Final Verdict
This Picun B8 Bluetooth Headphones review lands on a simple conclusion: if you want a battery monster with comfortable pads, quick EQ, and low-latency for videos — without paying ANC premiums — the B8 is a fantastic buy. It isn’t a metal-clad flagship and it won’t silence jet engines, but for everyday listening and marathon study/work weeks, it’s the set we’d recommend first.
