• Picun B8 — biggest strength: A 1000mAh battery rated at up to 120 hours of playtime, plus a 3.5mm jack so you can keep listening wired when the battery runs out.
• Picun B8 — biggest trade-off: It's an over-ear plastic build with sound-isolation-only noise control and a bulkier foldable frame, so it's less pocketable than an on-ear design.
• JBL Tune 510BT — biggest strength: JBL's signature Pure Bass tuning from 32mm dynamic drivers, in a lightweight on-ear frame that folds flat and ships with a travel case.
• JBL Tune 510BT — biggest trade-off: 40 hours per charge, Bluetooth 5.0, and no headphone jack at all — once the battery is empty, you're done until you recharge.
• Pick Picun B8 if you want maximum listening time per charge, over-ear coverage, and the option to plug in a cable.
• Pick JBL Tune 510BT if you want a lighter, more portable on-ear pair with bass-forward sound and quick 5-minute top-ups.
The Picun B8 is built around one number: 120 hours. Its 1000mAh battery is rated for more than 120 hours of playback per full charge, and a full charge takes about 2 hours. Do the math on a normal week and it's a genuinely different ownership experience — four hours of listening a day works out to roughly a month between charges. For anyone who has ever dug through a bag looking for a charging cable before a flight, that's the whole pitch.
The rest of the spec sheet backs up the travel-and-desk angle. The earcups rotate up to 60° and the headband adjusts, and the frame folds down, so it packs into a bag without much fuss. Padding is skin-friendly PU leather over elastic sponge, which is the right call for long sessions. On the audio side you get dual 40mm dynamic drivers, a 20Hz–20kHz frequency range, 32-ohm impedance, and three EQ modes — Pop, Bass Boost and Rock — cycled with a double-press of the EQ button. There's also a low-latency mode (triple-press the power button) rated at 50ms, which matters if you're gaming or watching video and don't want lip-sync drift.
Who should buy it: commuters, students, remote workers and frequent travelers who hate charging, want over-ear coverage, and like having a wired fallback. Who should skip it: anyone who wants the smallest possible pair for a pocket, or who insists on active noise cancellation — the B8 relies on passive sound isolation, not ANC.
JBL Tune 510BT: Who It's For
The JBL Tune 510BT plays a different game. It's an on-ear design — the earcups sit on your ears rather than around them — with 32mm dynamic drivers, 32-ohm impedance and a 20Hz–20kHz range. The sound signature is the point here: JBL Pure Bass, the deep, bass-forward tuning the brand is known for. If your library leans hip-hop, EDM, pop or action-heavy games, that low-end emphasis is exactly what you're paying for.
Battery is rated at up to 40 hours, with a Speed Charge feature that gives you about 2 hours of playback from a 5-minute charge. That's a shorter runtime than the Picun on paper, but the top-up behavior is arguably more useful day to day — a few minutes on a cable before you walk out the door covers a commute. Bluetooth 5.0 handles the wireless side with a 10-meter (roughly 33-foot) range, and multipoint connectivity lets you jump from a video on a tablet to a call on your phone without re-pairing.
Physically, this is the more portable of the two. It's lightweight with cushioned ear cups, and the foldable design plus the included travel carrying case make it easy to toss in a backpack. Controls run through buttons and a remote, with Google Assistant and Siri support for voice commands. The color is blue and the enclosure is plastic, same as the Picun.
Now the honest trade-offs. There's no headphone jack on the JBL Tune 510BT — it's wireless only. There's also no noise control at all, not even the passive isolation framing the Picun uses. And on-ear fit is a personal thing: some people love the lighter feel, others find on-ear pressure less comfortable over a long session than over-ear cups.
Side-by-Side: Which Should You Choose?
• Best for battery life → Picun B8. 120 hours rated versus 40 hours on the JBL.
• Best for bass-forward sound → JBL Tune 510BT. Pure Bass tuning and a bass-first signature are the core of this model.
• Best for wired listening → Picun B8. It includes a 3.5mm cable; the JBL Tune 510BT has no jack.
• Best for portability → JBL Tune 510BT. On-ear, lightweight, folds flat, and comes with a carrying case.
• Best for fit comfort over long sessions → Picun B8. Over-ear cups with PU leather and elastic sponge spread pressure around the ear rather than on it.
• Best for quick top-ups → JBL Tune 510BT. A 5-minute charge is rated for about 2 extra hours.
• Best for gaming and video → Picun B8. A 50ms low-latency mode plus wired mode when you need zero delay.
• Best for voice assistants → JBL Tune 510BT. Built-in Google Assistant and Siri support on the remote.
• Best for newer Bluetooth → Picun B8. Bluetooth 5.3 versus Bluetooth 5.0.
In my opinion, the Picun B8 is the smarter buy for most people. The 120-hour battery, over-ear comfort, Bluetooth 5.3, low-latency mode and the 3.5mm wired fallback cover more real-world situations — a dead battery never ends your listening session. I'd only steer you to the JBL Tune 510BT if bass-forward tuning and maximum portability matter more to you than runtime, and you're fine going wireless-only. Check the current price on Amazon before you commit, since that's the one variable that can flip this call.
FAQ
No. The JBL Tune 510BT is wireless-only over Bluetooth 5.0. If you want the option to plug in a 3.5mm cable, the Picun B8 includes one in the box.
The Picun B8 is rated for more than 120 hours of playback from its 1000mAh battery, with a 2-hour charge time. The JBL Tune 510BT is rated for up to 40 hours, and a 5-minute Speed Charge adds about 2 hours.
Neither has active noise cancellation. The Picun B8 uses passive sound isolation from its over-ear cups, while the JBL Tune 510BT lists no noise control at all — its on-ear design blocks some ambient sound by contact alone.
