• ASKUBSKU 3.5mm — biggest strength: a 3.5mm wired plug plus a semi in-ear, 45-degree fit that is designed to avoid ear-pressure pain on long wears, with an in-line remote for play/pause, volume and calls.
• ASKUBSKU 3.5mm — biggest trade-off: it is a passive design with sound isolation only, so it does not actively cancel noise, and it will not plug into a USB-C-only phone without an adapter.
• Keyronanc Active Noise Cancelling — biggest strength: true active noise cancellation you toggle with a double-tap on the control module, plus a USB-C jack built for iPhone 15/16/17 and other USB-C devices.
• Keyronanc Active Noise Cancelling — biggest trade-off: no 3.5mm option, so older phones, MP3 players, Kindles and handhelds with round jacks are simply out of reach.
• Who each pick is for: ASKUBSKU for the multi-device, old-jack crowd who want comfort and simplicity; Keyronanc for the modern USB-C owner who wants the hum of a bus or a plane pushed down.
This is a classic wired earbud, and I mean that as a compliment. The ASKUBSKU 3.5mm uses a 3.5mm jack, a dynamic driver rated from 20 Hz to 20 kHz, and a semi in-ear shape that sits at roughly a 45-degree angle into the ear rather than jamming deep into the canal. In practice that geometry is the selling point: the shell rests at the opening of the ear, so the "plugged up" pressure feeling many people get from full in-ear tips is largely avoided, and it is less likely to work loose when you move. A magnet on the back of each bud lets the two halves snap together, so you can hang them around your neck between calls instead of stuffing them in a bag.
The control story is straightforward and genuinely useful. There is an in-line module for play/pause, volume up and down, answering and hanging up calls, and even firing the camera shutter without touching the phone. The microphone is described as high-sensitivity and multi-directional with voice enhancement, which is the kind of spec that matters most for calls taken in a car, a stairwell or a windy street. Noise control is listed as sound isolation, not active cancelling — the semi in-ear fit physically blocks some ambient sound, but do not expect electronics to do the work.
Who should buy it? Anyone with a mixed drawer of devices: Samsung Galaxy A25, A15, A03s, S10, Note 9, older iPhones like the SE 1st gen, 6 and 6S, iPads, Switch, Kindle, MP3 players, Motorola and Pixel handsets with a headphone jack. Students, commuters and people who take a lot of voice calls will get the most out of it. Who should skip it? If your phone is a USB-C-only iPhone 15/16/17 or a jackless Android, or if you specifically want electronic noise cancelling for flights and open offices, this is the wrong tool.
The Keyronanc ANC-K20 is the opposite philosophy: it assumes your device speaks USB-C and that you want the world turned down. The headline feature is active noise cancellation, which you enable or disable with a double-tap on the control module — a nice touch, because ANC is not always desirable. On a quiet walk you can switch it off and save the processing; on a plane or a train you switch it on and let the electronics fight the drone.
The in-line remote handles play/pause, track skipping, call answering and the ANC toggle, and the microphone is described as noise-reducing for clearer voice pickup. Sound is pitched as Hi-Res with enhanced bass, crisp highs and balanced mids, and the impedance is listed at 32 ohm — a fairly standard, easy-to-drive figure for a wired bud. The enclosure is metal rather than plastic, which is a small but real durability signal, and the box includes eartips in S, M and L so you can actually get a seal. That seal matters twice over here: it improves bass and it gives the ANC a better starting point.
Compatibility is the crux. It is built for iPhone 15/16/17 series, Android phones with USB-C, and laptops and other USB-C devices. The age range covers kids through adults, and the brand offers a two-year warranty with contact-based support. Who should buy it? USB-C loyalists who commute on noisy transport, work in open-plan offices, or study in cafés and want the background muted without going wireless. Who should skip it? Anyone whose primary player has a round 3.5mm jack and no USB-C port — that includes a lot of older phones, Kindles and handheld consoles — plus anyone who dislikes in-ear tips and prefers the looser semi in-ear feel.
Side-by-Side: Which Should You Choose?
• Best for older phones, Kindles, Switch and MP3 players → ASKUBSKU 3.5mm. The 3.5mm jack covers the long list of legacy devices the Keyronanc simply cannot reach.
• Best for USB-C phones and laptops → Keyronanc Active Noise Cancelling. Built for iPhone 15/16/17 and USB-C Android, laptops and more.
• Best for long-wear comfort → ASKUBSKU 3.5mm. The semi in-ear 45-degree design is explicitly aimed at avoiding ear pressure and pain over long sessions.
• Best for call handling on either platform → a tie. Both have in-line remotes with a microphone; ASKUBSKU adds a camera shutter button, Keyronanc adds a noise-reducing mic and track skipping.
• Best for build feel → Keyronanc Active Noise Cancelling. Metal enclosure versus plastic, plus S/M/L eartips and a two-year warranty.
• Best for people who hate deep in-ear fit → ASKUBSKU 3.5mm. If tips bother you, the semi in-ear shape is the gentler option.
• Best for air travel and open offices → Keyronanc Active Noise Cancelling. Passive isolation can only do so much against engine drone.
If I had to pick one for myself, I would take the Keyronanc Active Noise Cancelling — my reasoning is simple: I work in noisy places, my daily phone and laptop are USB-C, and active noise cancelling is a capability the ASKUBSKU cannot replicate at any setting. The metal housing, three sizes of eartips and two-year warranty tip the balance further. That said, this is my opinion for my situation, not a universal answer. If your devices have round headphone jacks, if you wear buds for hours and hate the sealed-in feeling, or if you want the simplest possible wired bud for school and calls, the ASKUBSKU 3.5mm is the smarter buy and I would recommend it without hesitation. Check the current price on Amazon for whichever one matches your ports before you commit.
how to wired headphones work
A wired headphone sends the analog audio signal straight from your device's output jack into the drivers, so there is no battery, pairing or codec involved. On the ASKUBSKU 3.5mm the signal travels from the 3.5mm jack through a dynamic driver rated 20 Hz–20 kHz; on the Keyronanc it comes in over USB-C, which is why that model can also power active noise cancelling. The in-line remote on both sits between the cable and the buds and intercepts button presses for volume, calls and playback.
how to use wired headphones with iphone
It depends entirely on which iPhone you own. Older models with a round headphone jack — ASKUBSKU lists the SE 1st gen, 6 and 6S — plug the 3.5mm version straight in. If you have an iPhone 15, 16 or 17, those are USB-C, so the Keyronanc Active Noise Cancelling is the one that connects natively, with no adapter in the chain. Match the plug on the earbud to the port on the phone and you are done.
how to fix wired headphones no sound
Start at the jack. ASKUBSKU's own guidance notes that static electricity at a 3.5mm port attracts dust and debris, and if that is not cleaned the headset can fail to work — so check and clean the port, then reconnect. After that, confirm the plug is fully seated, test the earbuds on a second device to isolate whether the fault is the phone or the buds, and make sure the in-line control module has not been left in a paused or muted state.
how to wired headphones — no, seriously, how do you actually live with them?
Wired means no charging and no pairing, but it does mean cable management. Both of these have an in-line remote, so you control playback and calls from the cable rather than the screen. When you are not listening, ASKUBSKU's magnetic backs let the two buds clip together for wearing around your neck, which is the neatest trick either pair offers for daily carry.
