If you want one pair of headphones that does everything — travel, work calls, gaming, all-day listening — choose Picun B8; if you need something you can actually fall asleep in without your ears aching, choose Perytong Sleep Headphones. These two are barely the same category of product, and that's exactly why the choice is easy once you know how you'll use them.
• Picun B8 — biggest strength: A conventional over-ear design with a 120-hour battery, 40mm dynamic drivers, three EQ modes, Bluetooth 5.3 multipoint and a built-in mic. It's built for long sessions and hands-free calls.
• Picun B8 — biggest trade-off: It's a 12.3-ounce over-ear headphone with an oval earcup and a rigid headband. Great for sitting, commuting and working; genuinely unsuitable for lying on your side in bed.
• Perytong Sleep Headphones — biggest strength: A soft spandex headband with ultra-thin flat earpieces designed specifically for side sleepers. Passive noise cancellation, hands-free calling, and an auto-off that won't beep you awake.
• Perytong Sleep Headphones — biggest trade-off: Only about 10 hours of playback per 2-hour charge, and the audio hardware is tuned for sleep content — white noise, ASMR, audiobooks — not for critical music listening or gaming.
• Pick Picun B8 if you want one headphone for commuting, home office, phone and PC, and you don't plan to sleep in it.
• Pick Perytong if your main problem is falling asleep (or staying asleep) with audio on, especially if you sleep on your side and hate earbuds.
The B8 is a mainstream over-ear Bluetooth headphone, and its spec sheet reads like one. Dual 40mm dynamic drivers, a 20 Hz–20,000 Hz frequency range, 32 ohm impedance and 42 dB sensitivity — that's a normal, easy-to-drive headphone profile. What separates it from most budget over-ears is the battery: a 1000mAh cell rated at more than 120 hours of playback after a 3-hour charge. If you listen four hours a day, that's roughly a month between charges. In my opinion that single figure is the B8's whole personality. You stop thinking about charging, which is exactly what you want from a travel or desk headphone.
The feature set is practical rather than flashy. Three EQ modes (Pop, Bass boost, Rock) cycle with a double-press of the EQ button, and a low-latency mode toggles on with three presses of the power button — a 50 ms latency figure matters if you game or watch video. Bluetooth 5.3 gives you a 33-foot range and multipoint, so you can be connected to a laptop and a phone at once. There's a built-in mic for hands-free calls, touch controls for volume and playback, and a 3.5mm jack with an included audio cable if you ever want to go wired. The earcups rotate 60 degrees and the headband adjusts, and the whole thing folds.
Who should buy it: commuters, students, home-office workers, and anyone who wants one pair of headphones for music, movies, calls and games without babysitting a charger. Who should skip it: side sleepers and anyone who wants to wear headphones in bed. It weighs 12.3 ounces, the earcups are rigid ovals, and the design is not meant to be pressed against a pillow. Also skip it if you need active noise cancellation — noise control is listed as none, so isolation comes from the earcup seal alone. One practical note from the spec sheet: charge it with a 5V/1A or 5V/2A adapter only. Fast chargers can cause overheating, so keep that rule in mind.
The Perytong is a different animal entirely. It's a Bluetooth 5.4 headband made of stretchable spandex, with flat, thin earpieces that sit inside the fabric rather than around or inside your ear. That's the design that matters: side sleepers can lie directly on the earpiece without the pressure that makes earbuds and over-ears painful. The brand also builds in a cut-out so you can slide the speakers out and wash the headband, and the mesh lining is breathable — you can wear it as a sports headband too.
Battery is the honest trade-off. A 2-hour charge gives roughly 10 hours of playback (the product copy mentions 12–14 hours; the spec sheet lists a 10-hour average, so plan around the lower number). For a full night's sleep that's usually enough, and there's a thoughtful detail: when the battery dies, the headband shuts off silently instead of beeping — no bright lights, no warning tone waking you at 3 a.m. Audio is handled by a dynamic driver covering 20 Hz–20,000 Hz, with passive noise cancellation from the fabric itself, and a built-in mic lets you take calls without taking the headband off.
Who should buy it: side sleepers, light sleepers who use white noise or ASMR, people sharing a bed with a snorer, night-shift workers, and anyone with tinnitus who wants low-level audio overnight. Who should skip it: anyone buying their primary music or gaming headphone. There's no 3.5mm jack, no multipoint mentioned, no EQ modes, and the flat in-band speakers simply can't deliver the same stereo image and bass as a 40mm over-ear driver. If you want one headphone for everything, this isn't it.
Side-by-Side: Which Should You Choose?
• Best for sleeping → Perytong. The flat, thin earpieces and spandex band are the entire point of the product.
• Best for calls → Picun B8. Multipoint keeps it connected to two devices, and the mic plus touch controls make it a better desk headphone.
• Best for side sleepers → Perytong. Nothing about a 12.3-ounce over-ear is designed to sit against a pillow.
• Best for music and gaming → Picun B8. 40mm dynamic drivers, three EQ modes and a 50 ms low-latency mode are made for this.
• Best for travel and commuting → Picun B8. It folds, it goes wired via the 3.5mm jack, and the range is 33 feet.
• Best for washing → Perytong. The removable speaker cut-out lets you clean the headband, which matters for something you wear against your face nightly.
• Best for a gift → Depends on the person. A student or commuter gets more from the B8; a light sleeper or shift worker gets more from the Perytong.
If I had to pick one, I'd buy the Picun B8 — it covers more of my day, and the 120-hour battery means I'd rarely think about it. But that's only because I don't sleep in headphones. If your goal is falling asleep to white noise or ASMR without ear pain, the Perytong is the better product for you, full stop, and the B8 would be a mistake. In my opinion these aren't competitors so much as two tools for two different jobs. Buy the one that matches the job you actually have.
FAQ
how to headphones work
how to headphones on iphone
Turn the headphones on, open Settings > Bluetooth on the iPhone, and select the device from the list. Note that the Picun B8 shows its battery level in the corner of an iOS screen and lets you adjust phone volume with its own + and − buttons, a feature the spec sheet says is iOS-only.
how to headphone mode off
On the Picun B8, low-latency mode toggles by pressing the power button three times, so the same action turns it back off. On the Perytong there's no separate mode to disable — power the headband down and it disconnects; it also shuts off automatically when the battery runs out, without a warning beep.
how to headphones
If you mean pairing, both units use Bluetooth 5.3 or 5.4 and pair from your device's Bluetooth menu; the B8 also supports multipoint for two devices at once. If you mean charging, the B8 needs a 3-hour charge on a 5V/1A or 5V/2A adapter, while the Perytong needs about 2 hours for a night of playback. Check the current price on Amazon before you commit, since these two sit in very different budget brackets.
