• ASKUBSKU 3.5mm — biggest strength: A 5.9 ft cord plus a universal 3.5 mm jack, so it works with laptops, Chromebooks, PCs, tablets, the Switch, PS4/PS5 and a long list of Android phones.
• ASKUBSKU 3.5mm — biggest trade-off: It's a 3.5 mm plug, so phones and tablets that dropped the headphone jack need an adapter.
• Sidpro Earbuds — biggest strength: A USB-C connection with a built-in DAC, which is exactly what a newer iPhone or USB-C device needs to pass audio cleanly.
• Sidpro Earbuds — biggest trade-off: USB-C only — it won't plug into a standard 3.5 mm headphone port or older gear.
• Pick ASKUBSKU 3.5mm if you want one pair for the widest range of devices.
• Pick Sidpro Earbuds if your device is USB-C and you want a native fit without dongles.
The ASKUBSKU 3.5mm is a corded headphone built around flexibility. The headline feature is the 5.9 ft cable, which is noticeably longer than the short cords most earbuds ship with. In practice that means you can leave your laptop on a desk and still move around, plug into a TV or console across the room, or work out without yanking the connector. A longer cord also puts less strain on the plug itself, which is one of the first things to fail on wired buds.
The hardware is straightforward and honest: 32 ohm impedance, a dynamic driver, and a 20 Hz – 20,000 Hz frequency range — the standard full-range span for everyday listening. You get three sizes of silicone eartips (L/M/S), a semi in-ear shape that sits at roughly a 45-degree angle, and a carrying case in the box. The in-line control handles play/pause, volume up/down, call answer/hang-up, voice assistant, and even a camera shutter, so you're not reaching for your phone mid-task.
Sidpro Earbuds: Who It's For
The Sidpro Earbuds are purpose-built for USB-C audio, and the spec sheet makes that clear. The jack is USB-C, and there's a built-in DAC chip — that's the piece that converts digital audio to analog inside the plug, which is what lets a USB-C headphone talk to a phone that has no analog output at all. If you've ever plugged a passive USB-C dongle into a newer iPhone and gotten nothing, the DAC is the reason the Sidpro works and the cheap dongle doesn't.
The design is a half-in-ear shape with a thermoplastic elastomer (TPE) housing in white, using a balanced armature driver and a 20 Hz – 20,000 Hz range. Noise control is passive, which means it relies on the physical fit to block surrounding sound rather than any active circuitry — normal for this category, and something you feel most on a bus or in a shared office. The remote is a proper 3-in-1: single press to play/pause or answer, double press for the previous track, triple press for the next track, a two-second hold to reject a call, plus dedicated [+] and [-] volume buttons. A built-in mic handles hands-free calls without unplugging anything.
Who should buy it: anyone on a USB-C device — the newer iPhone lineup, USB-C iPads, and USB-C Android phones or laptops. The Sidpro lists a one-year warranty description, which is worth noting for a corded product. Who should skip it: if your gear has a 3.5 mm jack and no USB-C port, this simply won't connect, and you'd be paying for a connector you can't use.
Side-by-Side: Which Should You Choose?
• Best for device compatibility → ASKUBSKU 3.5mm. The 3.5 mm jack covers laptops, Chromebooks, PCs, consoles, Switch and Android phones with a standard port.
• Best for newer iPhone and USB-C gear → Sidpro Earbuds. USB-C with a built-in DAC is the native match.
• Best for track and call control depth → Sidpro Earbuds. Its remote adds skip-track and reject-call gestures on top of volume and play/pause.
• Best for fit options → ASKUBSKU 3.5mm. Three eartip sizes (L/M/S) let you tune the seal and comfort.
• Best for a lighter, half-in-ear feel → Sidpro Earbuds. The half-in-ear design sits shallower in the ear.
• Best if you hate adapters → it depends on your port. 3.5 mm device, go ASKUBSKU; USB-C device, go Sidpro.
• Best for a travel case in the box → ASKUBSKU 3.5mm. It ships with a carrying case.
In my opinion, the ASKUBSKU 3.5mm is the safer buy for most people, because a 3.5 mm plug still works with the largest number of devices — laptops, desktops, consoles, and older phones — and the 5.9 ft cord is a genuinely useful advantage you feel every day. I'd pick the Sidpro Earbuds only if your main device is USB-C, especially a newer iPhone, where the built-in DAC removes the adapter headache entirely. Both are simple, wired, no-battery products. Check the current price on Amazon before deciding, and let your port — not the marketing — make the call.
how to wired headphones work
A wired headphone sends an analog audio signal from your device down the cable to the driver inside each earbud, which turns it into sound. The ASKUBSKU 3.5mm uses a standard 3.5 mm analog jack with a 32 ohm dynamic driver. The Sidpro Earbuds are USB-C, so a built-in DAC converts the digital signal first, then feeds its balanced armature driver.
how to use wired headphones with iphone
On older iPhones with a Lightning port, the ASKUBSKU 3.5mm works through a Lightning-to-3.5 mm adapter. On newer USB-C iPhones, the Sidpro Earbuds plug straight in — its USB-C jack and DAC are designed for that. Either way, the in-line remote handles play/pause, volume and calls once connected.
how to fix wired headphones no sound
Start with the simple checks: confirm the plug is fully seated, try the other eartip channel, and test the headphones on a second device to isolate the fault. If the ASKUBSKU 3.5mm is silent, try a different 3.5 mm port or adapter; if the Sidpro Earbuds are silent on USB-C, try another USB-C port. A cable or connector fault is the usual culprit on corded models.
how to wired headphones
Using wired headphones is plug-and-play: connect the jack, then control playback with the in-line buttons. The ASKUBSKU 3.5mm gives you play/pause, volume, call answer/hang-up, voice assistant and a camera shutter on its button control. The Sidpro Earbuds add double-press previous track, triple-press next track, and a two-second hold to reject a call.
