• Koss CL/3i — biggest strength: A transparent "Sound of Koss" retro shell with a OneTouch inline mic and remote, plus a limited lifetime warranty and a wide 60–20,000 Hz rated range.
• Koss CL/3i — biggest trade-off: It's a plain in-line remote with no noise control and no stated cable length — you're paying for the design and the brand, not for extra features.
• yobola Headphones Earbuds 3.5mm — biggest strength: A 4.2 ft cable, explicit volume control on the remote, and sound isolation, at a spec sheet that reads like a do-everything travel pair.
• yobola Headphones Earbuds 3.5mm — biggest trade-off: A narrower 20–20,000 Hz rating, a 1-year warranty, and an ABS/PC plastic build that won't feel as special as the Koss clear shell.
• Choose Koss CL/3i if: you want the retro clear look, the lighter 0.01 kg build, and a brand name you recognize with a lifetime warranty.
• Choose yobola Headphones Earbuds 3.5mm if: you want volume buttons on the cord, a longer cable, and sound isolation for noisy classrooms, buses, or commutes.
The CL/3i is the Koss answer to "what if a pair of earbuds looked like it walked out of 1994?" The earpiece is a rounded-tip in-ear design with a transparent plastic enclosure, so you can literally see the dynamic driver inside. Koss calls it a retro theme, and it delivers on that — from the clear cord to the clear carrying case, this is a pair you notice. It's also light: 0.01 kg, which is the kind of weight you stop feeling after a couple of hours.
Audio is rated 60–20,000 Hz. That's a narrow low-end floor compared to the yobola, meaning the Koss is tuned for a punchy, mid-forward character rather than sub-bass rumble. Koss describes it as deep bass, crisp highs, and a full midrange, which lines up with a 60 Hz bottom — fine for pop, podcasts, and games, less ideal if you want to feel a bass drop.
Who should buy it: retro-style hunters, people who want a recognized brand and a limited lifetime warranty, and anyone who mostly listens in quieter places where a clear shell and a light fit matter more than sealing out the world. Who should skip it: anyone who needs volume buttons on the cord, a specified cable length, or sound isolation on a loud train.
yobola Headphones Earbuds 3.5mm: Who It's For
The yobola set is the practical one. The headline feature is the inline remote: answer and end calls, play and pause, skip tracks, and — crucially — adjust volume, all from the cord. That's one more control than the Koss gives you, and if you've ever fumbled for your phone on a crowded bus, you know how much that matters. yobola also claims the built-in mic delivers crystal-clear calls with effective noise reduction, and the spec sheet lists sound isolation as the noise control method.
The cable is 4.2 ft. That's a real number, and it's the kind of length that works when your phone is in a backpack pocket or plugged into a desktop tower rather than sitting on your lap. The 32 ohm impedance is a standard, easy-to-drive figure, so phones, laptops, MP3 players, and school tablets won't struggle to power it.
The trade-offs are honest ones. The frequency range is 20–20,000 Hz — wider on paper than the Koss, but with no stated driver tuning behind it, so don't read that as a promise of better bass. The enclosure is ABS and polycarbonate plastic in a white finish, and the warranty runs 1 year versus Koss's limited lifetime coverage. It's also an in-ear design with no stated weight, so you're trusting the fit rather than a number.
Who should buy it: students, commuters, travelers, and anyone plugging into a school Chromebook or an older MP3 player who wants volume control on the wire and some isolation from the outside world. Who should skip it: anyone who wants a distinctive look, a longer warranty, or a branded audio heritage — this is a workhorse, not a statement.
• Best for inline call and music control → tie. Both have an inline mic and remote for answering calls and controlling playback.
• Best for volume control on the cord → yobola Headphones Earbuds 3.5mm. Its remote explicitly adjusts volume; the Koss OneTouch remote covers media and call control but not volume.
• Best for retro style and transparency → Koss CL/3i. Clear enclosure, clear cord, clear case — it's a design piece.
• Best for blocking out a noisy room → yobola Headphones Earbuds 3.5mm. Sound isolation is listed; the Koss lists no noise control at all.
• Best for a longer reach to your device → yobola Headphones Earbuds 3.5mm. A 4.2 ft cable is specified; Koss doesn't publish a length.
• Best for warranty peace of mind → Koss CL/3i. Limited lifetime warranty versus 1 year.
• Best for lightweight wear during workouts and travel → Koss CL/3i. 0.01 kg and a durable in-ear build aimed at listeners on the go.
• Best for easy-to-drive sound on basic devices → yobola Headphones Earbuds 3.5mm. 32 ohm impedance plays nicely with phones, MP3/4 players, and computers.
• Best for a wider rated frequency range → yobola Headphones Earbuds 3.5mm. 20–20,000 Hz versus the Koss's 60–20,000 Hz floor.
In my opinion, the yobola Headphones Earbuds 3.5mm is the smarter buy for most people, because the inline remote does more: volume plus track and call control, a specified 4.2 ft cable, and sound isolation for the noisy places where wired earbuds actually get used. I'd pick the Koss CL/3i only if the clear retro look is the reason you're buying — and if a limited lifetime warranty and a lighter build outweigh losing volume buttons on the cord. If price is the deciding factor, check the current price on Amazon before you commit, since that's the one thing a spec sheet can't tell you.
It's a small microphone built into the cord rather than the earcup, usually paired with a button or two so you can take calls and control playback without touching your phone. Both the Koss CL/3i and the yobola set use this design — the Koss calls it OneTouch mic plus remote, and yobola adds volume adjustment to the same module.
Plug the 3.5mm jack into your computer's headphone or headset port, then select the earbuds as your output and input device in your sound settings. Both pairs use a standard 3.5mm jack, so laptops and desktops with a combo or separate mic/headphone port will work — if your PC has separate green and pink ports, you may need a splitter.
Both handle calls through their inline mic and remote, so on paper they're comparable. yobola explicitly claims noise reduction for clearer calls and lists sound isolation, while the Koss focuses on the OneTouch answer/end control — so if call clarity in a loud place matters most, I'd lean yobola.
Both list a standard 3.5mm jack and wired connectivity, and yobola names iPhone, iPad, Samsung, computers, and MP3/4 players in its listing. That said, newer phones without a headphone jack will need an adapter — the 3.5mm plug is the deciding factor, not the brand.
