If you want a washable, ultra-thin headband you can wear lying down on a long flight or at your desk, choose Fulext Sleep Headphones; if you need marathon battery life, real over-ear drivers and multipoint pairing for travel and the office, choose Picun B8.
• Fulext Sleep Headphones — biggest strength: a headband-and-headphones 2-in-1 design with 0.25-inch flat speakers, so nothing presses into your ears when you sleep or lean back in a plane seat.
• Fulext Sleep Headphones — biggest trade-off: up to 10 hours per charge and sound isolation only (no active noise cancellation), so it is a personal-listening device, not a noise-blocking travel rig.
• Picun B8 — biggest strength: a 1000mAh battery rated for more than 120 hours of playtime, dual 40mm drivers, 3 EQ modes, Bluetooth 5.3 and multipoint connection.
• Picun B8 — biggest trade-off: it is a full over-ear headphone (0.35 kg) with PU leather cushions, so it is bulky for side sleeping and adds weight on your head.
• Who each pick is for: Fulext for sleepers, side sleepers and anyone who wants headphones hidden inside a soft headband; Picun B8 for fliers, commuters and office workers who want long battery life and proper stereo sound.
The Fulext Sleep Headphones are built around one idea: get the sound off your ears. The speakers are only 0.25 inch thick and sit inside a stretchy headband made from 80% nylon, 12% polyester and 8% spandex, with a breathable mesh lining. The control module sits between the speakers rather than on top of them, which is exactly why side sleepers can lie down without a hard pod digging into their head. If you have ever pulled earbuds out at 2 a.m. because they hurt, that design detail is the whole pitch.
For travel and office use, the appeal is different. The headband doubles as an eye cover, it is foldable and lightweight at 75 g, and it pairs over Bluetooth 5.2 with a range of about 13.7 meters — enough to leave your phone on the desk or in the seat pocket and still stay connected. A 2-hour charge gives up to 10 hours of talk or audio time, and there is a built-in microphone plus on-band volume and track controls, so you can take a call without reaching for your phone. It is also machine washable once you remove the control pod, which matters if you wear it to the gym, on a run or through a sweaty commute.
Who should skip it? Anyone who wants serious bass, active noise cancellation or a headphone that survives a full week of heavy listening between charges. The Fulext relies on sound isolation, not noise cancellation, and 10 hours is a single long-haul flight, not a multi-day trip. If your priority is blocking engine roar with a sealed over-ear cup, this is not that product.
The Picun B8 is the opposite philosophy: put as much headphone as possible around your ears and keep it running for weeks. Dual 40mm dynamic drivers with three EQ modes (Pop, Bass boost, Rock) give you a proper over-ear listening experience, and the 1000mAh battery is rated at more than 120 hours of playtime — the brand frames that as roughly 30 days at 4 hours a day. For a frequent flier or someone who works at a desk all day and forgets to charge things, that is the headline feature.
Comfort and travel practicality are clearly the second pillar. The earcups use skin-friendly PU leather over highly elastic sponge, the headband adjusts, and the earcups rotate up to 60°, so the B8 folds down and packs reasonably flat. Bluetooth 5.3 with multipoint connection means you can stay linked to a laptop and a phone at the same time, which is genuinely useful in an office where calls and music come from two different devices. It also ships with a 3.5mm audio cable, so you can go wired when a Bluetooth connection is not an option — a nice fallback on older in-flight entertainment systems.
The trade-offs are real too. At 0.35 kg it is roughly four and a half times the weight of the Fulext, and there is no noise cancellation listed — just the passive seal of the earcups. Touch controls are convenient but less predictable than physical buttons when you are half asleep or wearing gloves. And it is an over-ear headphone, so side sleeping is out.
• Best for sleeping and side sleeping → Fulext Sleep Headphones. Ultra-thin 0.25-inch speakers, a mid-mounted control pod and a soft, washable headband.
• Best for battery life → Picun B8. More than 120 hours per charge versus up to 10 hours on the Fulext.
• Best for the office → Picun B8. Multipoint connection, a built-in microphone, EQ modes and a wired option make it the better desk companion.
• Best for workouts, running and yoga → Fulext Sleep Headphones. Breathable, quick-dry fabric, sweat stays out of your eyes and the whole thing is machine washable.
• Best sound quality → Picun B8. Dual 40mm dynamic drivers and three EQ modes versus the Fulext's thin flat speakers.
• Best for the lightest feel on your head → Fulext Sleep Headphones. 75 g and foldable, versus 0.35 kg for the B8.
• Best for sharing one pair across devices → Picun B8. Bluetooth 5.3 with multipoint beats single-device pairing for that job.
My Verdict
For most people reading this, I would buy the Picun B8. It covers the widest range of everyday situations — flights, the office, commuting, movies — with a 120-hour battery, 40mm drivers, multipoint Bluetooth 5.3, a wired fallback and a foldable frame. That combination is hard to argue with for travel and office use. I would only switch to the Fulext Sleep Headphones if sleeping or side-sleeping in a headband is your actual priority, or if you want a washable, sweat-friendly headband for workouts and want nothing pressing on your ears. If you are weighing the cost, check the current price on Amazon for both before deciding.
are bluetooth headphones allowed on flights
Yes. Bluetooth headphones are permitted on commercial flights, and airplane mode on your phone still allows Bluetooth to stay on. Note that many seatback entertainment systems do not transmit Bluetooth audio themselves, which is why a wired 3.5mm option like the one included with the Picun B8 is useful as a backup.
do bluetooth headphones work on flights
They work for anything stored on or streamed through your own device, such as music, downloads and podcasts. The Fulext Sleep Headphones pair over Bluetooth 5.2 with roughly 13.7 meters of range and up to 10 hours of playtime, while the Picun B8 uses Bluetooth 5.3 with about 33 feet of range and more than 120 hours per charge.
are bluetooth headphones ok on flights
Yes, they are fine for in-flight use as long as you follow crew instructions during taxi, takeoff and landing. Neither of these models has active noise cancellation — the Fulext uses sound isolation and the Picun B8 relies on the passive seal of its PU leather earcups — so expect reduced, not eliminated, cabin noise.
do delta flights have bluetooth for headphones
That is an airline and aircraft-specific question rather than a headphone question, and it varies by fleet and cabin. The safer plan is to bring a headphone that also works wired: the Picun B8 includes a 3.5mm audio cable, while the Fulext Sleep Headphones are wireless-only.
