If you want marathon battery life and an over-ear fit that never asks you to think about charging, choose Picun B8; if you need a compact, sweat-resistant earbud with a quick top-up charge, choose Sony WF-C510. Both support Bluetooth multipoint, so both can stay paired to two devices at once — the real split is over-ear endurance versus in-ear portability.
• Picun B8 — biggest strength: A 1000mAh battery rated for up to 120 hours of playback, plus an over-ear design with 40mm dynamic drivers, 3 EQ modes, and a foldable, rotating earcup build.
• Picun B8 — biggest trade-off: It's a full-size over-ear headphone with a plastic enclosure, no water-resistance rating in the specs, and a 2-hour charge time, so it's bulkier and slower to top up.
• Sony WF-C510 — biggest strength: Truly wireless in-ear buds with an IPX4 water-resistance rating, Ambient Sound Mode, DSEE upscaling, and quick charging (5 minutes for up to 1 hour of playback).
• Sony WF-C510 — biggest trade-off: Shorter battery (up to 11 hours per charge, up to 22 hours with the case) and no active noise cancellation — the specs list noise control as "None."
• Who Picun B8 is for: Travelers, students, and desk workers who want one headphone that lasts for days between charges and can also run wired via the included 3.5mm cable.
• Who Sony WF-C510 is for: Commuters, gym-goers, and anyone who wants buds that disappear into a pocket and survive sweat and splashes.
The Picun B8 is built around one idea: don't make me charge this thing. The 1000mAh battery is rated for more than 120 hours of playback, which at roughly 4 hours of listening a day works out to about a month between charges. That's the headline spec, and for a lot of people it's the whole story. Pair it with Bluetooth 5.3, a 33-foot range, and automatic reconnection if you wander back within range within 5 minutes, and you get a headphone you can leave in a bag and forget about.
The design leans practical rather than precious. It's an over-ear model with 40mm dynamic drivers, 32-ohm impedance, and a 20Hz–20kHz frequency range. There are three EQ modes — Pop, Bass Boost, and Rock — cycled with a double-press of the EQ button, plus a low-latency mode you toggle by pressing power three times, which matters if you're gaming or watching video and don't want lip-sync drift. The earcups rotate 60 degrees and the headband adjusts, so it should sit comfortably across a range of head shapes, and the PU leather and sponge padding is aimed at long sessions. Controls are a mix of touch and buttons: touch to answer calls, touch-and-hold three seconds to reject, and a built-in mic for hands-free calls.
Who should skip it: if you want earbuds that vanish into a pocket, this isn't that. The over-ear form factor is inherently bulkier, there's no water-resistance rating in the specs, and a full charge takes about 2 hours. It's a stay-put headphone, not a gym companion.
Sony WF-C510: Who It's For
The WF-C510 goes the opposite direction: minimum mass, maximum convenience. These are truly wireless in-ear buds with 6mm dynamic drivers and a compact cylindrical charging case designed to slip into a pocket or bag. The spec sheet lists a 31g total weight, which tells you how little is going on your head. The fit is the point — light, compact, and tuned for all-day wear rather than long listening marathons.
Battery is rated up to 11 hours in the buds and up to 22 hours total with the case. That's far less than the Picun, but Sony counters with quick charging: 5 minutes in the case buys you up to 1 hour of playback. That's the kind of number that saves you on the way out the door. Multipoint lets the buds hold two devices at once and automatically route an incoming call to whichever device is ringing, and there's a built-in microphone with a wind noise reduction structure for hands-free calls.
Two features stand out for real-world use. Ambient Sound Mode pipes in your surroundings so you can hear traffic, announcements, or a colleague walking up — and Voice Focus specifically pulls human voices forward while suppressing other noise, which is a genuinely useful trick in an open office or on a platform. DSEE upscales compressed audio files, and Sony's Headphones Connect app adds EQ adjustment if the stock tuning isn't your taste. The IPX4 rating means splashes and sweat are fine, so these work for running, cycling, and humid commutes.
Who should buy it: commuters, gym-goers, runners, and anyone who wants earbuds they can pocket and forget. Who should skip it: if you want noise cancellation, the specs list noise control as "None" — Ambient Sound Mode is the opposite of isolation. And if you hate charging things frequently, 11 hours per charge plus a case is a much shorter leash than the Picun's 120.
• Best for battery life → Picun B8. Up to 120 hours per charge versus up to 11 hours per bud (22 with case).
• Best for portability → Sony WF-C510. Truly wireless buds in a small case, 31g total, versus a foldable over-ear headphone.
• Best for workouts and weather → Sony WF-C510. IPX4 water resistance; the Picun's specs list no water-resistance rating.
• Best for long desk or couch sessions → Picun B8. Over-ear padding, 60-degree rotating earcups, and adjustable headband for hours of wear.
• Best for situational awareness → Sony WF-C510. Ambient Sound Mode and Voice Focus keep you tuned into your surroundings.
• Best for wired fallback → Picun B8. Includes a 3.5mm audio cable for zero-latency, zero-battery listening.
• Best for quick top-ups → Sony WF-C510. Five minutes of charging yields up to an hour of playback; the Picun needs about 2 hours for a full charge.
• Best for gaming and video → Picun B8. A 50ms low-latency mode you can switch on, plus 40mm drivers for a bigger sound stage.
• Best for audio tweaking → Both, differently. Picun gives you three on-board EQ presets; Sony gives you app-based EQ plus DSEE upscaling.
In my opinion, most people should buy the Sony WF-C510. It's the more flexible everyday object: it goes to the gym, survives rain, tells you when a car is coming, and tops up in five minutes when you've forgotten to charge it. The multipoint implementation — automatically answering whichever paired device is ringing — is exactly what you want from a commuter bud.
I'd only steer you to the Picun B8 if battery anxiety is your main enemy or you specifically want an over-ear headphone that can also run wired. The 120-hour rating and the 3.5mm cable make it the better pick for flights, dorm rooms, and all-day desk work. Decide which of those two people you are, and the choice is easy.
FAQ
what is multipoint bluetooth headphones
Multipoint is a Bluetooth feature that lets one headphone stay connected to two devices at the same time — say a laptop and a phone. When a call comes in, the headphone switches to the ringing device automatically instead of making you disconnect and re-pair. Both the Picun B8 and Sony WF-C510 support it.
Yes, if they support multipoint. The Picun B8 connects over Bluetooth 5.3 with a range up to 33 feet, and the Sony WF-C510 pairs with two Bluetooth devices at once, routing calls to the correct one. Without multipoint, a headphone can usually only hold one active connection at a time.
which headphones have bluetooth multipoint
Both headphones compared here have it. The Picun B8 lists multipoint connection alongside Bluetooth 5.3, and the Sony WF-C510 explicitly supports pairing with two devices simultaneously. If multipoint is a must-have, both qualify — the decision comes down to over-ear versus in-ear.
do these headphones have noise cancelling
No. The Sony WF-C510's specs list noise control as "None" — it uses Ambient Sound Mode to let sound in, not block it out. The Picun B8 lists sound isolation, which is passive blocking from the over-ear cushions, not active noise cancellation. Neither cancels noise electronically.
