• Maeline's biggest strength: Ten individually packaged earbuds in ten different colors, all with a 3.5mm right-angle plug — built for handing out, not for one person.
• Maeline's biggest trade-off: No microphone, no remote, no volume control. It's an audio-only earbud, so calls and track skipping aren't part of the deal.
• Sidpro's biggest strength: A USB-C connection with a built-in microphone, a three-in-one control button and separate volume buttons — everything you need for calls and playback.
• Sidpro's biggest trade-off: It's a single pair with a USB-C jack, so it won't fit older 3.5mm headphone ports at all.
• Who Maeline is for: Teachers, librarians, coaches, event organizers — anyone who needs a stack of spare earbuds.
• Who Sidpro is for: One person with a USB-C phone or tablet who wants a mic and controls on a wired set.
The Maeline Bulk Earbuds 10 is, first and foremost, a quantity product. You get ten earbuds, each in its own package, in pink, orange, yellow, red, white, grey, purple, black, blue and green. That color spread matters more than it sounds: when thirty students or a whole classroom of library visitors are using earbuds at once, distinct colors make it obvious whose is whose. It's a small design choice that solves a real, everyday logistics problem.
The build leans lightweight and ergonomic, with soft silicone tips and a rounded in-ear shape intended for extended wear. The plug is the interesting part — a right-angle 3.5mm jack, which sits flush against the device and resists accidental pull-out. If you've ever watched a kid yank a straight plug out of a Chromebook by walking away with the cable, you understand why that L-shape is the right call here. The 20 Hz–20,000 Hz dynamic driver covers the full audible range, which is plenty for spoken-word content, video, and casual music.
What it deliberately leaves out is just as important. There's no microphone, no remote and no volume control. That's a minimalist choice, and it keeps the earbud simple — nothing to configure, nothing to break off in a pocket. In my opinion, that's exactly right for a classroom or lending-desk scenario, where the priority is that the thing works every time someone plugs it in.
Sidpro Earbuds: Who It's For
The Sidpro Earbuds is the opposite kind of product: one pair, built around a single modern phone. The connection is USB-C, not 3.5mm, and it's aimed squarely at the iPhone 17/16/15 families and other USB-C devices. If your phone dropped the headphone jack, this is the category that actually fits it without an adapter.
The feature list is where it separates itself. There's a built-in microphone for hands-free calls, plus a three-in-one control button that handles a lot: one click plays or pauses, two clicks go back a track, three clicks skip forward, one click answers a call, the same button hangs up, and a two-second hold rejects a call. Separate [+] and [-] buttons handle volume directly on the cable. For anyone who's tired of pulling a phone out of a pocket mid-walk, that's a genuinely useful setup.
Sidpro also lists a smart DAC chip, which is the piece that lets a USB-C headset convert digital audio properly — relevant because USB-C earbuds without one can behave inconsistently across devices. The driver here is a balanced armature type rather than the dynamic driver in the Maeline pair, with the same 20 Hz–20,000 Hz range. The half-in-ear shape is described as ergonomic and aimed at minimizing surrounding noise; the noise control is passive, meaning it relies on the fit rather than active electronics. The housing uses a thermoplastic elastomer and the color is white.
Who should buy it: someone with a USB-C phone or tablet who wants one reliable wired headset for calls, music, video, and gaming, and who wants cable controls. Who should skip it: anyone with a 3.5mm-only device, and anyone who needs multiple pairs — this is a one-pack.
Side-by-Side: Which Should You Choose?
• Best for phone calls → Sidpro Earbuds. The built-in microphone and answer/reject controls are the deciding factor.
• Best for cable control → Sidpro Earbuds. Volume buttons plus a multi-function button versus no controls at all on the Maeline.
• Best for older and mixed devices → Maeline Bulk Earbuds 10. The 3.5mm plug fits iPhones, iPads, Chromebooks, laptops, PCs, Android tablets, MP3 and CD players, and fitness equipment.
• Best for modern USB-C phones → Sidpro Earbuds. A USB-C jack and a smart DAC chip are built for that port.
• Best for a secure, snag-resistant connection → Maeline Bulk Earbuds 10. The right-angle L-shaped plug resists accidental pull-out, which matters in busy rooms.
• Best for one person who wants everything in one pair → Sidpro Earbuds. Mic, remote, volume, and noise isolation in a single white headset.
• Best for color-coded organization → Maeline Bulk Earbuds 10. Ten distinct colors make ownership obvious at a glance.
One thing worth flagging for both: the data sheets don't list prices, and prices on listings change often. Check the current price on Amazon using the button on this page before you commit, especially if you're ordering the ten-pack in volume.
If I were buying for myself — one person, one phone, taking calls and controlling playback from the cable — I'd pick the Sidpro Earbuds. The microphone, the three-in-one button and the separate volume keys are things I'd actually use daily, and the USB-C connection matches how most current phones are built.
If I were outfitting a room, a class, or an event, I'd buy the Maeline Bulk Earbuds 10 without hesitating. Ten packaged earbuds, ten colors, and a plug that won't yank out is exactly what that job needs. In my opinion, these two aren't really competitors — they solve different problems, and you should buy the one that matches yours.
FAQ
how to use wired headphones with iphone
how to wired headphones work
A wired headphone sends the audio signal from your device down the cable to the drivers inside the earbud, which convert it into sound. The Maeline pair uses a dynamic driver; the Sidpro pair uses a balanced armature driver, and adds a smart DAC chip because USB-C carries a digital signal that has to be converted. Both list a 20 Hz–20,000 Hz frequency range.
how to fix wired headphones no sound
Start at the connection, since that's the usual culprit. Check that the plug is fully seated — the Maeline's right-angle 3.5mm plug is designed to resist pull-out, but it still needs to be pushed in all the way — and try another device to isolate whether the problem is the earbud or the port. On the Sidpro, confirm you're in a USB-C port, since it won't work in a 3.5mm jack.
how to wired headphones
Using wired headphones is straightforward: plug in, then control playback from your device. The Maeline Bulk Earbuds 10 has no remote or volume control, so all playback and volume adjustments happen on the phone, tablet or computer. The Sidpro Earbuds puts those controls on the cable — one click to play or pause and answer calls, two clicks for the previous track, three for the next, and dedicated [+] and [-] buttons for volume.
