• LORELEI X8 biggest strength: Pure plug-and-play 3.5mm wired audio with a 40mm dynamic driver, a built-in microphone, and a tangle-free nylon cable — nothing to charge, nothing to pair.
• LORELEI X8 biggest trade-off: Wired only, with no Bluetooth, no EQ modes, and no active noise control, so you're tethered to your device and limited to whatever sound the driver delivers out of the box.
• Picun B8 biggest strength: Wireless Bluetooth freedom with an enormous 120-hour battery rating, 3 EQ modes, multipoint connection, and a 3.5mm cable included as a wired backup.
• Picun B8 biggest trade-off: Heavier build at 12.3 ounces, touch controls that take practice, no noise cancellation, and a charging warning that means you must stick to 5V/1A or 5V/2A adapters rather than fast chargers.
• Who LORELEI X8 is for: Anyone who wants a lightweight, foldable, corded headphone for a phone, tablet, computer, or MP3 player without ever thinking about charging.
• Who Picun B8 is for: Anyone who wants over-ear wireless listening for travel, commuting, movies, or gaming and hates recharging — plus a wired fallback when the battery eventually runs out.
The LORELEI X8 is an unapologetically simple headphone. It connects through a 3.5mm jack, uses a 40mm dynamic driver, and covers a 20 Hz to 20,000 Hz frequency range at 32 ohms impedance. That impedance figure matters more than it looks: 32 ohms is easy to drive, so a phone, tablet, laptop, or basic MP3 player can push it without a separate amplifier. You plug in, you press play, and you're done.
What it does best is remove friction. The 1.45-meter cable is nylon-wrapped and described as tangle-free, which is a small thing until you've spent two minutes untangling a cheap rubber cord before every commute. It folds, it weighs 210 grams, and the dark purple finish with circular on-ear cushions gives it a bit of personality without shouting. There's a built-in microphone and voice control, so calls and voice assistants work through the cable rather than a battery. The theme is listed as video game, and honestly that fits — a wired connection with no latency is exactly what you want for gaming or video where lip-sync matters.
Who should buy it: students, desk workers, commuters on short trips, and anyone who has ever picked up a wireless headphone only to find it dead. If your devices still have a headphone jack — or you keep a dongle around — this is the low-maintenance option.
Picun B8: Who It's For
The Picun B8 is built around one headline number: 120 hours of playtime from a 1000mAh battery, with a 3-hour charge time. Picun frames that as roughly 30 days of use at 4 hours a day, which is a reasonable way to think about it — this is a headphone you charge occasionally rather than nightly. If you've ever owned a wireless headphone that died mid-flight, that figure is the entire pitch.
Under the hood it's Bluetooth 5.3 with a stable range up to 33 feet, plus multipoint connection so it can hold onto more than one device at a time. There are dual 40mm dynamic drivers and three EQ modes — Pop, Bass boost, and Rock — cycled by pressing the EQ button twice. Latency is rated at 50 milliseconds, and there's a low-latency mode you toggle by pressing the power button three times, which is the setting you'd want for gaming or watching video. A built-in microphone handles hands-free calls, and the touch controls cover answering, rejecting, and waking a voice assistant.
Comfort is where Picun clearly put thought into the design. The earcups are over-ear with oval cushions made from PU leather and elastic sponge, and the earcups rotate 60 degrees while the headband adjusts. That's a genuinely useful combination for long sessions — the rotation helps the cups sit flat against different head shapes rather than pressing at an angle. The trade-off is weight: 12.3 ounces is noticeably more than the LORELEI X8's 210 grams, and you'll feel that difference on a long walk.
Two practical notes worth flagging. First, the B8 includes a 3.5mm audio cable, so if the battery does run out you can still listen wired. Second, the charging warning is specific and real: use a 5V/1A or 5V/2A adapter only, and avoid fast chargers or high-power adapters, which the manufacturer says can cause abnormal heating or damage. That's a genuine ownership habit to build, not a throwaway line.
Who should buy it: travelers, commuters, remote workers, and anyone who wants one headphone for music, calls, movies, and gaming without a cord. Who should skip it: if you want the lightest possible thing on your head, refuse to manage a battery, or can't be bothered learning touch gestures, the simpler wired X8 is the better fit.
Side-by-Side: Which Should You Choose?
• Best for zero maintenance → LORELEI X8. No battery, no pairing, no charging habits — plug into a 3.5mm jack and it works.
• Best for wireless freedom → Picun B8. Bluetooth 5.3 with a 33-foot range and multipoint connection lets you move around and switch devices.
• Best for lighter weight → LORELEI X8. At 210 grams it's a fraction of the B8's 12.3 ounces, which matters over long listening sessions.
• Best for sound tweaking → Picun B8. Three EQ modes (Pop, Bass boost, Rock) let you shift the tuning; the X8 gives you one fixed sound signature.
• Best for low-latency gaming and video → Tie, with a caveat. The B8's 50ms latency plus low-latency mode is good for wireless, but the X8's wired connection has no wireless delay at all.
• Best for calls on the go → Picun B8. A built-in mic plus touch controls for answering and rejecting calls beats a corded mic you have to stay near.
• Best for device compatibility → Picun B8. It works wirelessly with anything Bluetooth and still includes a 3.5mm cable for everything else.
In my opinion, the Picun B8 is the better buy for most people, and it's the one I'd choose. The 120-hour battery, multipoint Bluetooth, three EQ modes, and 60-degree rotating earcups solve more real problems — travel, commuting, calls, movie nights — than a wired headphone can. The LORELEI X8 is genuinely good at what it does, and if you want a light, foldable, corded headphone you never charge, it's a smart pick. But for the average shopper juggling a phone, a laptop, and a commute, the B8 covers more ground. Check the current price on Amazon before deciding, since that's the one variable I can't weigh for you.
how to headphones work
Headphones turn an electrical audio signal into sound using drivers — in both of these, a 40mm dynamic driver. The LORELEI X8 receives that signal through a 3.5mm wired connection, while the Picun B8 receives it over Bluetooth 5.3 or through its included 3.5mm cable. Wired delivery has no wireless delay; Bluetooth adds a small amount, which the B8 rates at 50 milliseconds.
how to headphones on iphone
For the LORELEI X8, connect the 3.5mm plug using an appropriate adapter if your iPhone lacks a headphone jack. For the Picun B8, open Bluetooth settings, pair the headphone, and it connects wirelessly — Picun notes that on iOS devices the headphone battery level appears in the corner of the screen, and the on-ear volume buttons sync with the phone's volume.
how to headphone mode off
If you mean switching the Picun B8 from wireless to wired, just plug in the included 3.5mm audio cable — it doubles as a corded mode when you'd rather not use Bluetooth. There's no separate "headphone mode" toggle on the LORELEI X8, since it's wired-only by design. On the B8, pressing the power button three times also toggles the low-latency mode on and off.
how to headphones
If you're asking how to use these headphones day to day: the LORELEI X8 is plug-and-play — connect the 3.5mm jack to a phone, tablet, computer, or MP3 player and use the inline voice controls. The Picun B8 needs a one-time Bluetooth pairing, then touch controls handle playback, calls, and voice assistant access, with a 3-hour charge giving up to 120 hours of playback. Charge the B8 only with a 5V/1A or 5V/2A adapter.
