• AILIHEN C8 biggest strength: 3.5mm wired simplicity with inline mic, remote and volume control, a foldable adjustable headband, and a 59-inch braided cord that resists kinking and twisting.
• AILIHEN C8 biggest trade-off: The volume buttons won't work on a PC, and using the mic on a computer requires an extra adapter. It also has no built-in volume limit for young ears.
• Acer OHW328 biggest strength: Two jacks in one cable (3.5mm and USB-C), over-ear cups with multi-directional movement, and a 85/94dB safe-listening switch aimed at school-age kids.
• Acer OHW328 biggest trade-off: It's a kids-first design (3–16 years), so adults who want a neutral everyday headphone may find the styling and volume ceiling limiting.
• Pick the AILIHEN C8 if you want a flexible, foldable all-rounder for yourself or an older teen.
• Pick the Acer OHW328 if you're buying for a child and want adapter-free device switching plus hearing protection.
The C8 is a straightforward corded headphone. A single 3.5mm plug, a 59-inch braided cable, and an inline remote with a microphone and volume buttons. That combination is what most people actually need: plug into a phone, laptop, Chromebook, MP3 player or tablet and listen. No pairing, no charging, no app.
The build leans toward portability and comfort. The headband is adjustable and the ear cups fold up, so it collapses small enough to drop in a bag. The on-ear cups use a rounded, faux-leather covered design with cushioned padding, and the full-sized on-ear construction gives you some passive isolation from surrounding noise — enough that bass and mid detail don't get buried on a bus or in a shared room. The dynamic drivers cover the standard 20Hz–20kHz range.
Who should buy it? In my opinion, this is the right pick for a teen or adult who wants one wired headphone that does calls, music, classes and video meetings. The mic-and-remote setup makes it genuinely useful for online learning and casual calls, and the folding frame suits travel.
Acer OHW328: Who It's For
The OHW328 is built around one problem parents know well: the device jack changes. School Chromebooks, iPads, gaming consoles, laptops and tablets don't all use the same port. Acer solves it by putting both a 3.5mm AUX plug and a USB-C plug on the same headphone, so you don't hunt for an adapter before class or a car ride.
The second half of the design is hearing safety. There's a dual safe sound mode that caps output at 85dB for school and home, with a 94dB setting for travel where there's more background noise. For a parent, that's the feature that decides the purchase — it puts a ceiling on volume regardless of what the child does with the source device.
Comfort is handled with an over-ear layout rather than on-ear. The cups have 54x40mm openings and move in multiple directions (about ±10°), which reduces pressure points on growing heads. The headband is soft and adjustable and the whole thing weighs 5.29 oz. Acer rates it for ages 3 to 16, and the adjustability means it can stretch from a toddler to a teen, with adults able to wear it too. Materials are BPA-free and the headphone carries a one-year warranty.
Who should buy it? Parents buying for school, homework, road trips and shared family devices — especially households juggling both USB-C tablets and 3.5mm laptops. Who should skip it? Adults who want a neutral, full-volume everyday headphone for music and calls. The safe-listening ceiling and kid-oriented tuning aren't aimed at that buyer, and there's no inline mic/remote feature listed. If you want to make calls from your laptop, the C8's mic and controls are the more practical route.
Side-by-Side: Which Should You Choose?
• Best for younger kids (3+) → Acer OHW328. Adjustable headband, over-ear cups sized for growing ears, and a stated 3–16 age range.
• Best for hearing protection → Acer OHW328. The 85/94dB dual safe sound mode is the single biggest differentiator between these two.
• Best for calls and inline controls → AILIHEN C8. Built-in mic, remote and volume control make it the better choice for online meetings and phone calls.
• Best for older teens and adults → AILIHEN C8. No volume cap, on-ear fit, and a foldable frame that travels well.
• Best for portability → AILIHEN C8. The cups fold into the palm of your hand, and the braided cord is designed not to kink or twist.
• Best for long-wear comfort with big ears → Acer OHW328. The 54x40mm openings and ±10° cup movement are purpose-built to avoid pressure points.
• Best all-rounder for one person → AILIHEN C8. If you're buying for yourself, not a child, the C8 covers more of what you'll actually do day to day.
In my opinion, most people reading this who are buying for themselves or an older teen should get the AILIHEN C8. It's the more versatile everyday wired headphone: mic, inline volume and call controls, a foldable frame, and a braided 3.5mm cord that holds up to being stuffed in a backpack. The main caveats are the PC volume-button limitation and the mic adapter requirement on computers — worth knowing before you buy.
If you're buying for a child, though, I'd pick the Acer OHW328 without hesitating. The 85/94dB safe sound mode, the over-ear cups that fit growing heads, and the dual 3.5mm/USB-C jacks solve the two problems parents actually complain about. Different jobs, different winners — and that's the honest answer here.
how to wired headphones work
A wired headphone takes an analog audio signal from your device through the 3.5mm (or USB-C) plug and drives the drivers inside the ear cups — here, dynamic drivers covering 20Hz to 20kHz. No battery or pairing is involved, which is why both of these work the moment you plug them in.

Plug the 3.5mm plug into a Lightning-to-3.5mm or USB-C-to-3.5mm adapter, then play audio as normal. The AILIHEN C8's inline mic and volume controls work over that connection; the Acer OHW328 has a native USB-C plug that fits USB-C iPads and iPhones directly, with the 3.5mm plug for older devices.
how to fix wired headphones no sound
Check the obvious first: the plug seated fully, the correct jack selected, volume turned up, and the cable free of sharp bends. Because the C8 uses a braided cord and both models rely on the plug connection, a damaged plug or a wrong output setting on the device is the usual cause. Test the headphone on a second device to isolate whether the fault is the headphone or the source.
how to wired headphones
Wired headphones are used simply by plugging in and pressing play — there's no setup step. On the C8, the inline remote handles track changes and calls; on the OHW328, the safe-listening switch sets the volume ceiling at 85dB or 94dB before your child starts listening.
