If you want marathon battery life and a wired fallback for the money, choose Picun B8; if you need app-based sound tuning and a quicker recharge, choose JBL Tune 720BT.
• Picun B8 — biggest strength: A claimed 120 hours of playback from a 1000mAh battery, plus a 3.5mm cable so it still works when the battery is flat.
• Picun B8 — biggest trade-off: No app, no active noise cancellation, and a 3-hour charge that asks for a low-power 5V/1A or 5V/2A adapter.
• JBL Tune 720BT — biggest strength: JBL Pure Bass tuning you can reshape in the free JBL Headphones App, with a 2-hour charge and a 5-minute top-up that adds roughly 3 hours.
• JBL Tune 720BT — biggest trade-off: 76 hours instead of 120, no 3.5mm jack at all, and no wired mode to fall back on.
• Buy the Picun B8 if you want the longest possible time between charges and a cord for planes, trains or dead-battery days.
• Buy the JBL Tune 720BT if you want a lighter, app-tunable headphone with faster charging and voice-aware calls.
The Picun B8 is built around one idea: go as long as possible without a charger. The spec sheet lists a 1000mAh battery and a claimed 120 hours of playback, which the brand frames as roughly 30 days of listening at 4 hours a day. Whether or not you hit that exact number, the design intent is clear — this is a headphone for people who hate hunting for cables. A full charge takes about 3 hours.
Sound comes from dual 40mm dynamic drivers with a 20Hz–20kHz range, 32-ohm impedance and 42dB sensitivity. There are three EQ modes — Pop, Bass Boost and Rock — cycled with a double-press of the EQ button, so you can nudge the tuning without an app. There's also a low-latency mode (press power three times) rated at 50ms, which matters if you're watching video or gaming and don't want the audio trailing the picture.
Comfort and practicality are clearly thought through: PU leather and elastic sponge padding, an adjustable headband, 60° rotating earcups and a foldable frame. Bluetooth 5.3 gives you a stated 33-foot range with auto-reconnect if you wander back within 5 minutes. Multipoint connection, a built-in mic and touch controls handle calls, and there's a 3.5mm jack plus a cable in the box. You also get a two-year warranty and a one-year refund guarantee per the brand.
Who should buy it: long-haul travelers, commuters, students and anyone who wants a wired option as a backup. Who should skip it: if you need active noise cancellation, app-based EQ or a lighter headphone, look elsewhere — the B8 lists no noise control and weighs 12.3 ounces, which is on the heavy side. Also note the charging caveat: it's designed for 5V/1A or 5V/2A adapters only, so a high-power fast charger isn't recommended.
The JBL Tune 720BT leans on the JBL Pure Bass sound signature and, more importantly, on the free JBL Headphones App. That app is the real differentiator: you get EQ customization, voice prompts in your chosen language, and a level of control the Picun simply doesn't offer. If you like fiddling with how your music sounds, this is the more flexible headphone.
Battery life is listed at up to 76 hours, with a 2-hour full charge over USB-C and a genuinely useful trick — a 5-minute quick charge that adds about 3 hours of playback. That's the spec that matters most for people who forget to charge: five minutes on the cable before you walk out the door and you're covered. The 720BT also uses 40mm dynamic drivers with a 20Hz–20kHz range and 32-ohm impedance, but a much higher 101dB sensitivity, which is part of why it plays loud from a phone with ease. Latency is listed at 60ms.
Call handling is a highlight. The earcup buttons manage playback and calls, and Voice Aware lets you hear your own voice while you talk so you don't shout. On the control side, the sheet lists Siri plus Amazon Alexa and Google Assistant support, though the control method is described as touch.
Who should buy it: app-tinkerers, Android and iOS users who want voice assistant access, and commuters who value a fast top-up. Who should skip it: if you want a wired fallback, this isn't it. There's no 3.5mm jack, so once the battery dies you're done until you charge. It also lists sound isolation rather than active noise cancellation, so don't expect ANC. It's considerably lighter at 220g, which most people will notice over a long day.
• Best for battery life → Picun B8. 120 hours versus 76 is a big gap, and it's the headline reason to pick the Picun.
• Best for charging speed → JBL Tune 720BT. A 2-hour full charge and a 5-minute/3-hour top-up beat the Picun's 3-hour charge.
• Best for sound customization → JBL Tune 720BT. The JBL Headphones App gives you EQ control; the Picun gives you three preset modes and nothing more.
• Best for wired listening → Picun B8. It has a 3.5mm jack and ships with an audio cable; the JBL has no jack at all.
• Best for lower latency → Picun B8. 50ms versus 60ms, with a dedicated low-latency mode for video and gaming.
• Best for call clarity features → JBL Tune 720BT. Voice Aware and voice prompts are genuinely useful on calls.
• Best for lighter wear → JBL Tune 720BT. 220g versus 12.3 ounces makes a real difference over hours.
• Best for noise blocking → Neither, strictly speaking. The Picun lists no noise control; the JBL lists sound isolation, not active cancellation. Don't buy either expecting ANC.
If I had to pick one, I'd buy the Picun B8 — and the reason is simple. In my opinion, the combination of a claimed 120-hour battery, a 3.5mm wired fallback, multipoint, three EQ presets and a two-year warranty covers the widest range of everyday situations, from a dead-battery flight to a week away from a charger. The JBL is the better pick if app tuning and fast charging matter more to you than raw endurance, and I'd happily recommend it to anyone who lives in the JBL app. But as an all-rounder that never leaves you stranded, the Picun gets my vote.
Yes. The Picun B8 lists a claimed 120 hours of playback; the JBL Tune 720BT lists up to 76 hours. If long time between charges is your priority, the Picun wins on paper.
No. The JBL Tune 720BT has no 3.5mm jack, so it's wireless-only. The Picun B8 includes a 3.5mm audio cable and a jack, so it keeps working when the battery runs out.
The JBL Tune 720BT, thanks to the free JBL Headphones App with EQ control and voice prompts. The Picun B8 offers three preset EQ modes — Pop, Bass Boost and Rock — but no app.
Neither lists active noise cancellation. The Picun B8 lists no noise control at all, and the JBL Tune 720BT lists sound isolation. If you need true ANC, both of these are the wrong category — check the current price and specs on Amazon for each before deciding, since the page provides a button for that.
