Reasons to consider it
- Picun advertises up to 120 hours of battery life
- Bluetooth and 3.5 mm modes provide connection flexibility
- Three selectable EQ modes
- Foldable over-ear design targets travel and daily use
Reasons to skip it
- No active noise cancellation

Short answer: The Picun B8 is a budget over-ear headphone built around an unusually high 120-hour battery claim, selectable EQ, and a 3.5 mm wired fallback. It may suit low-cost everyday listening, but it is not an ANC headphone and its performance claims need to be treated cautiously.
The B8 competes less on ecosystem features and more on specification quantity. Picun advertises Bluetooth 5.3, 40 mm drivers, three EQ modes, a 1000 mAh battery, wired and wireless playback, and up to 120 hours of use.
Those claims sound strong for the price category. They do not, however, prove sound quality, comfort, call clarity, or actual runtime. This article separates the documented feature list from conclusions that require a production sample.
Picun B8 key specifications
| Specification | Published claim |
|---|---|
| Wearing style | Foldable over-ear |
| Drivers | 40 mm |
| Bluetooth | Version 5.3 |
| Battery | 1000 mAh |
| Runtime claim | Up to 120 hours |
| EQ modes | Pop, Bass Boost, and Rock |
| Wired input | 3.5 mm |
| Active noise cancellation | No |
| Low-latency mode | Listed; performance not independently measured |
| Call microphone | Built in for Bluetooth calls |
The 120-hour claim is the obvious headline, but the more durable buying distinction is wireless plus wired operation without ANC.
Battery life is the main attraction
If the published maximum is approached in real use, the B8 would require charging far less often than typical earbuds and many mainstream over-ear headphones. That can help students, travelers, and occasional users who dislike battery maintenance.
Runtime depends on volume, EQ, connection conditions, calls, battery age, and how Picun defines its test. We have not reproduced the result, so it should be treated as an upper limit.
A large runtime claim also should not distract from charging behavior. Check the live listing and manual for charging time, included cable, indicator behavior, and whether Bluetooth playback is available while charging.
Wired mode is a useful fallback
The 3.5 mm input can connect to computers, controllers, airplane systems, and other analog sources. It can also keep audio available when the battery is empty.
Microphone and button behavior often change in analog mode. Do not assume that the built-in Bluetooth microphone, EQ modes, or all controls remain active through a basic 3.5 mm cable. Verify the current manual and the exact cable supplied.
For competitive games, a wired connection may reduce Bluetooth delay, but the headphone’s acoustic positioning and microphone quality still require testing.
Three EQ modes do not establish sound quality
Picun lists Pop, Bass Boost, and Rock presets. These provide quick tonal changes without an app, which can be convenient for listeners who use several devices.
Preset names do not reveal frequency response, distortion, imaging, or consistency between units. Bass Boost may add impact but can also mask vocals depending on the tuning. We do not describe the B8 as balanced, detailed, or powerful without measurements.
Buyers who care about neutral monitoring should seek independent frequency-response data or a headphone intended for production work.
Comfort and build remain open questions
An over-ear shape can distribute pressure around the ear rather than directly on it, but comfort depends on pad opening, depth, clamp, heat, glasses, and head size.
The folding hinges improve portability while creating additional moving parts. Handle them by the reinforced sections, avoid twisting the cups beyond their intended range, and use a case if the headphone will travel in a packed bag.
Our headset comfort guide explains how weight, pad geometry, clamp, and microphone needs interact during long sessions.
No active noise cancellation
The B8 should not be confused with an ANC headphone. Its pads may passively reduce some environmental sound when they seal well, but passive isolation is not electronic cancellation.
That distinction matters on aircraft, trains, and in shared offices. If reducing steady low-frequency noise is a priority, compare verified ANC performance rather than relying on terms such as “noise isolating.”
Calls and low-latency mode
Picun lists a built-in microphone for wireless calls. This confirms the function, not speech quality in wind, traffic, or a reverberant room. There is no boom microphone close to the mouth.
The product also advertises a low-latency mode. Latency depends on the headphone, source device, codec, app, and content path. Without measurements, it should not be treated as a guarantee for rhythm games, competitive play, or live audio monitoring.
Who should buy the Picun B8?
The B8 may suit:
- Budget buyers who prioritize infrequent charging.
- Casual music, video, and study use.
- People who want Bluetooth plus a 3.5 mm fallback.
- Users who prefer quick hardware EQ modes.
- Occasional travelers who do not require ANC.
Consider another model if:
- Effective ANC is essential.
- You need measured sound accuracy.
- Professional microphone quality matters.
- You need verified low latency.
- You want a compact premium travel case and established support network.
Frequently asked questions
Does the Picun B8 have ANC?
No. The B8 may provide passive isolation from its over-ear pads, but Picun does not list active noise cancellation.
Can the B8 be used with a wire?
Yes. Published materials list a 3.5 mm wired mode. Check which controls and microphone features remain available in that mode.
Is the 120-hour battery figure guaranteed?
No. It is a manufacturer claim under unspecified or manufacturer-defined conditions. Actual runtime varies, and PickScoreLab has not measured it.
Is the B8 good for gaming?
It can play game audio and offers wired and advertised low-latency options, but competitive suitability requires direct latency, imaging, and microphone testing.
Final verdict
The Picun B8 is easy to shortlist when battery maintenance and price matter more than ANC or premium materials. Its wired fallback and EQ presets add useful flexibility.
The safest decision is to treat 120 hours and low latency as claims to verify, not conclusions. Confirm the live ASIN, warranty, return policy, and current manual before ordering.
