If you want a wood-housed USB-C earbud that plugs straight into a modern iPhone or Android phone with no adapter, choose Symphonized Wooden USB-C; if you need a long-cord 3.5mm pair that works with laptops, Chromebooks, tablets and older gear, choose ASKUBSKU 3.5mm.
• Symphonized Wooden USB-C — biggest strength: a USB-C plug that matches iPhone 15 through 17 and most current Android phones, plus a wood housing and an in-line remote with mic. No dongle required.
• Symphonized Wooden USB-C — biggest trade-off: it simply will not work in a 3.5mm hole, and its passive noise cancellation only blocks sound physically, not electronically.
• ASKUBSKU 3.5mm — biggest strength: a 5.9 ft cord that reaches across a couch or a desk, and a 3.5mm plug that fits laptops, Chromebooks, PCs, tablets, consoles and older phones.
• ASKUBSKU 3.5mm — biggest trade-off: plastic housing and a standard headphone jack mean no USB-C device will accept it — you need an adapter on a modern iPhone.
• Who each is for: Symphonized for phone-first listeners who want a tidy corded setup; ASKUBSKU for desk, laptop and couch listeners who want reach and wide compatibility.
Symphonized builds this model around a USB-C connector and a wooden enclosure. The driver is an 8 mm dynamic driver with 32 ohm impedance and a stated frequency range of 18Hz–22kHz, so it covers the audible spectrum with a little extra reach at the low end on paper. The earpiece shape is a rounded tip, and the housing is designed to sit at the entrance of the ear canal — visible when worn, which the brand treats as an intentional design choice rather than a flaw.
The fit system is where this pair earns its keep. You get foam and silicone ear tips in three sizes, so you can hunt down the seal that actually holds. A good seal is what makes passive noise cancellation work on a corded earbud; there's no battery, no active circuitry, just a physical block against the outside world. If you commute, work in an open office, or study in a noisy room, that seal is the whole game.
The in-line remote handles calls, playback and volume, and there's a built-in HD mic for hands-free talking. The control method is listed as touch on the remote, and the audio path is wired — the Bluetooth field in the sheet refers to the broader product family, not this specific corded connection.
Buy it if you carry a USB-C phone, want one cable from pocket to ear, and value a distinctive wood look. Skip it if your main listening device is a laptop with a round 3.5mm jack, or if you want a long cord to stretch across a room — the cable here is a standard earbud length.
ASKUBSKU goes the other direction entirely. The headline feature is a 5.9 ft cable — noticeably longer than the short cord on most earbuds. That extra length is genuinely useful: you can leave a laptop on a desk and still move around, plug into a TV across the room, or work out without yanking the connector. A longer cord also spreads stress away from the plug, which the brand frames as a durability benefit.
The fit follows a semi in-ear, 45-degree angle design with soft silicone tips in three sizes (L/M/S). The pitch is comfort over long sessions — no pressure feeling, no sore ears after hours — and the angled insertion is meant to keep the buds from sliding out during movement. Noise control is described as sound isolation, which is again passive: the tip seals, the outside noise drops.
Sound specs are a 32 ohm dynamic driver with a 20Hz–20,000Hz range, which is the standard full-range window. The enclosure is plastic, the earpiece shape is a bud, and the controls are physical buttons rather than touch — pause/play, volume, answer/hang up, voice assistant and a camera shutter. That shutter button is a small thing, but if you take a lot of selfies or group shots on a tripod, it's handy.
Compatibility is the real story. The 3.5mm jack works with a long list of Android phones, older iPhones (SE 1st gen, 6, 6S, 5, 5S), iPads, Switch, PS4, PS5, MP3 players, laptops, Chromebooks and Windows machines. A carrying case and eartips come in the box.
Buy it if you bounce between a laptop, a tablet and older hardware, or you want reach and physical buttons. Skip it if your only device is a USB-C phone with no headphone jack — you'd need an adapter, which defeats the point.
• Best for a USB-C phone (iPhone 15–17, most Android) → Symphonized Wooden USB-C. Direct plug, no adapter.
• Best for laptops, Chromebooks, PCs and consoles → ASKUBSKU 3.5mm. The 3.5mm jack is the universal one.
• Best cable reach → ASKUBSKU 3.5mm. 5.9 ft versus a standard earbud cord.
• Best physical control feel → ASKUBSKU 3.5mm. Button controls beat touch for pause, volume and calls when you're moving.
• Best distinct build and materials → Symphonized Wooden USB-C. Wood enclosure, rounded tip, visible housing.
• Best for extended wear comfort → ASKUBSKU 3.5mm. Semi in-ear, 45-degree angled tips designed to avoid ear pressure.
• Best for a tidy, single-cable commute setup → Symphonized Wooden USB-C. In-line remote and mic, nothing extra to carry.
• Best for mixed-device households → ASKUBSKU 3.5mm. It covers more of the gear you probably already own.
In my opinion, this comes down to the port in your pocket, not to specs. If your daily driver is a USB-C phone, I'd buy the Symphonized Wooden USB-C — plugging straight in with no adapter is a real daily convenience, and the wood housing plus three-size tip kit make it feel considered. If your listening happens at a desk, on a couch or across a mix of laptops and older devices, I'd buy the ASKUBSKU 3.5mm — the 5.9 ft cord and universal jack solve problems the Symphonized pair can't. Check the current price on Amazon for whichever one matches your hardware before you commit.
how to wired headphones work
A wired headphone sends an analog electrical signal from your device's audio output, through the cable, to a driver inside the earpiece. That driver converts the signal into sound. Both pairs here use a dynamic driver at 32 ohm impedance — Symphonized over an 18Hz–22kHz range and ASKUBSKU over 20Hz–20,000Hz — and each has a mic plus in-line controls on the cord. No battery, no pairing, no charging.
how to use wired headphones with iphone
It depends on the iPhone's port. Symphonized Wooden USB-C is built for USB-C iPhones (15 through 17), so it plugs in directly. ASKUBSKU 3.5mm fits older iPhones with a round headphone jack — SE 1st gen, 6, 6S, 5 and 5S are listed — but on a newer USB-C iPhone you'd need an adapter. Match the plug to your phone and you're done.
how to fix wired headphones no sound
Start with the simple checks: make sure the plug is fully seated, try the other ear tip size to rule out a seal problem, and test the headphones on a second device to isolate whether the fault is the earbud or the source. Check that the in-line remote isn't paused or at zero volume. On USB-C, confirm your phone actually outputs audio over USB-C. If both devices stay silent, the cable or driver has likely failed.
what is the difference between noise isolating and noise cancelling headphones
Noise isolation is passive — the ear tip physically blocks outside sound, which is what both of these pairs do (Symphonized lists passive noise cancellation, ASKUBSKU lists sound isolation). Noise cancelling is active: microphones sample ambient noise and electronics cancel it out, which needs power. Neither of these is active noise cancelling, so a good tip seal is what determines how quiet your listening gets.
