How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a wired USB-C earbud that plugs straight into a modern phone or tablet with no charging, no pairing and no battery to babysit, choose BENEWY USB C Headphones; if you need long wireless listening sessions, over-ear comfort and a battery that keeps going for days, choose Picun B8.
• BENEWY USB C Headphones — biggest strength: A pure wired USB-C connection with an inline remote, so there is nothing to charge and nothing to pair. In my opinion that simplicity is the whole point of this product.
• BENEWY USB C Headphones — biggest trade-off: It is an in-ear bud with a fixed cable. There is no Bluetooth, no active noise cancellation, and no over-ear cushioning — just sound isolation from the fit.
• Picun B8 — biggest strength: A 1000mAh battery rated for up to 120 hours of playtime, dual 40mm drivers, three EQ modes and Bluetooth with multipoint connection.
• Picun B8 — biggest trade-off: It is a wireless over-ear headphone that weighs considerably more than a pair of buds and depends on charging — plus it has no active noise cancellation either.
• Who each pick is for: BENEWY for anyone who wants plug-and-play audio on a USB-C phone, tablet or laptop; Picun B8 for travellers, students and home listeners who want long battery life and over-ear comfort.
The BENEWY USB C Headphones are, at their core, a simplicity play. The cable ends in a USB-C plug, so there is no pairing step, no Bluetooth menu, no "forget this device" troubleshooting and no battery percentage to watch. Plug it in and the audio routes through. The inline remote sits on the cable and handles the basics: one press of the middle button plays or pauses, one press answers a call, pressing again ends it, a two-second hold rejects a call, a double click jumps to the previous track, a triple click skips forward, and the separate [+] and [-] buttons handle volume. That is a complete control set without ever touching the phone.
The hardware underneath is modest but sensible. The drivers are 14.2mm dynamic units with a 32 ohm impedance, a 20 KHz frequency response and 110 dB sensitivity — the kind of spec sheet that says "easy to drive from a phone" rather than "needs a headphone amp." The buds are in-ear with a bud shape, and the package includes a pair of eartips plus a fabric carrying case, so the fit can be adjusted and the whole thing stows away without tangling loose in a bag. The earpieces themselves are light — around 4.81 g — which matters if you wear buds for long stretches.
Who should buy it? Anyone whose phone, tablet or laptop has already moved to USB-C and who wants a spare pair that always works. It is also a good fit for gaming sessions on a tablet or a laptop, and for calls, since the microphone is built into the remote. The compatibility list is genuinely broad — recent iPhone 15 through 17 families, iPad Pro and iPad Air models, a long list of Samsung Galaxy S and A series phones, Google Pixel, OnePlus and HTC devices. That breadth is the selling point: one pair of buds that covers most of the modern USB-C world.
Who should skip it? If you hate cables, if you want to walk around the room while listening, or if you need over-ear cups that sit around your ears rather than inside them, this is not your product. There is no Bluetooth here at all — it is wired only. And the isolation you get is passive sound isolation from the eartip seal, not active noise cancellation. In my opinion the BENEWY is best understood as a dependable, no-fuss wired tool rather than a feature showcase.
The Picun B8 is the opposite philosophy: it wants to be the only headphone you carry. The headline number is battery life — a 1000mAh cell rated for more than 120 hours of playback after a full charge, with a charge time of around 3 hours. Picun frames that as roughly 30 days of listening at 4 hours a day. Even if you take that as a best-case figure, the practical takeaway is real: this is a headphone you charge occasionally, not nightly. For a commuter, a student or someone who works from home and wears headphones all day, that removes a genuine annoyance.
The audio side uses dual 40mm dynamic drivers, a 32 ohm impedance, a 20 Hz – 20,000 Hz frequency range and three EQ modes you cycle with a double press of the EQ button — Pop, Bass boost and Rock. There is also a low-latency mode you toggle by pressing the power button three times, and the spec sheet lists audio latency at 50 milliseconds, which is the sort of detail that matters if you are watching video or gaming and hate lip-sync drift. Connectivity is Bluetooth with multipoint, and the box includes a 3.5mm audio cable, so you can fall back to a wired connection when you want to. A built-in microphone and touch controls handle calls: a short touch answers, three short touches wake or dismiss the voice assistant, and a three-second touch rejects a call.
Comfort is clearly a design priority. The earcups are over-ear with an oval shape, made from PU leather over elastic sponge, and the headband is adjustable with a 60° rotating earmuff design. That combination is what makes long sessions tolerable — the cups swivel to sit flat against your head instead of pressing at an angle. The headphone also folds, which is a small thing that matters a lot in a backpack. Note that it has no active noise cancellation — noise control is listed as none — so isolation comes from the over-ear seal alone.
Who should buy it? Travellers, students, home-office workers and anyone who wants one headphone for music, movies, games and calls without thinking about charging. Who should skip it? If you want something that disappears into a pocket, an over-ear headphone that weighs 12.3 ounces is not that. If you refuse to manage a battery at all, the wired BENEWY is the cleaner answer. And if you need active noise cancellation for a noisy commute or a flight, neither of these two provides it.
• Best for zero-maintenance listening → BENEWY USB C Headphones. No battery, no pairing, no charging cable to lose.
• Best for battery life → Picun B8. A 1000mAh battery rated up to 120 hours, with roughly a 3-hour charge time.
• Best for travel and long sessions → Picun B8. Over-ear PU leather cups, elastic sponge padding, an adjustable headband and a 60° rotating earmuff design.
• Best for portability → BENEWY USB C Headphones. Light buds (about 4.81 g per earpiece) with a fabric carrying case and a pair of spare eartips.
• Best for calls on the go → a tie, with a caveat. Both have a built-in microphone; the BENEWY uses an inline button remote, the Picun B8 uses touch controls.
• Best for wired reliability across devices → BENEWY USB C Headphones. The compatibility list spans recent iPhone, iPad, Samsung Galaxy, Pixel, OnePlus and HTC USB-C hardware.
• Best for sound tuning flexibility → Picun B8. Three EQ modes (Pop, Bass boost, Rock), dual 40mm drivers and a 50 ms low-latency mode for video and gaming.
• Best if you want to move around while listening → Picun B8. Bluetooth with multipoint and a rated range of up to 33 feet; the BENEWY is tethered by its cable.
• Best if you hate charging rules → BENEWY USB C Headphones. Worth noting the Picun B8 asks for a 5V/1A or 5V/2A adapter and warns against fast chargers, which is one more thing to remember.
If I were buying for myself, I would pick the Picun B8. The reason is straightforward: for the way most people actually listen — moving around the house, commuting, watching video, taking calls — the combination of up to 120 hours of battery, over-ear comfort, three EQ modes and a low-latency mode covers more ground than a wired bud can. I would accept the weight and the charging habit in exchange for that flexibility. That said, I would recommend the BENEWY USB C Headphones without hesitation to anyone who wants a permanently plugged-in pair for a USB-C phone, tablet or laptop and never wants to think about a battery again. These are two different tools, not two versions of the same one.
how to headphones work
A headphone converts an electrical audio signal into sound using drivers — dynamic drivers in both of these products. The BENEWY uses 14.2mm dynamic drivers fed through a wired USB-C connection, while the Picun B8 uses dual 40mm dynamic drivers fed by Bluetooth or, with the included 3.5mm cable, a wired connection.
how to headphones on iphone
It depends on the iPhone's port, which is why the BENEWY lists iPhone 15 through 17 models and recent iPads among its compatible devices — those use USB-C, so you plug the earbuds straight in. The Picun B8 connects over Bluetooth instead, so it pairs wirelessly rather than plugging into a Lightning or USB-C port.
how to headphone mode off
"Headphone mode" usually just means audio is routed to the connected device. Unplug the BENEWY's USB-C connector and the phone returns to its speaker. On the Picun B8, disconnect or power off the Bluetooth connection, or switch the phone's output back to the speaker in its audio settings.

Getting started is simple with either. The BENEWY is plug-and-play over USB-C with an inline volume and call remote. The Picun B8 needs a one-time Bluetooth pairing, then you use its touch controls and EQ button; it also supports multipoint, so it can stay connected to more than one device.
