If you want a cable-free, sweat-proof set for music and workouts, choose EarFun Free 2S; if you need a plug-and-play wired headset with an inline mic for PC calls, classes and meetings, choose ASKUBSKU USB Earbuds. That's the short version — and for anyone shopping specifically for wired in ear earbuds for PC, the choice usually comes down to whether you value freedom of movement or a rock-solid, zero-latency USB connection.
• EarFun Free 2S — biggest strength: True wireless freedom with a 7mm dynamic driver, 4 microphones, an EQ app, IPX7 waterproofing and both USB-C and wireless charging.
• EarFun Free 2S — biggest trade-off: It's Bluetooth only with no headphone jack, so it needs charging and pairing, and its 7-hour average battery life is per-charge rather than endless.
• ASKUBSKU USB Earbuds — biggest strength: A 7.5 ft tangle-free USB-A cable with an inline mic and mute button — plug it in and it just works, no battery, no pairing, no charging.
• ASKUBSKU USB Earbuds — biggest trade-off: Wired-only, USB-A only, and no app, EQ or waterproof rating — it's a communication tool more than a music-first headphone.
• Who each pick is for: EarFun Free 2S for commuters, gym-goers and casual listeners who want wireless convenience; ASKUBSKU for students, office workers and anyone on Zoom or Teams calls at a desktop or laptop.
The EarFun Free 2S is built around sound and freedom. Its 7mm composite dynamic driver is tuned for powerful bass with detailed mids and treble, and the 20Hz–20kHz frequency range at 32 ohm impedance covers everything from podcasts to playlists. Four built-in microphones handle calls by isolating your voice and cutting down background noise, which matters if you take calls outdoors or in noisy rooms. And the EarFun App adds multi-EQ adjustment, custom touch controls, a battery display and a low-latency game mode — real flexibility you don't often get at this tier.
Buy it if you want wireless earbuds for music, calls, the gym and travel, and you like the idea of tuning the sound yourself. Skip it if you need a guaranteed wired connection for a desktop PC, hate managing battery levels, or want a physical mute button for long meeting days. As the name suggests, there's no jack here — it's Bluetooth or nothing.
ASKUBSKU USB Earbuds: Who It's For
The ASKUBSKU USB Earbuds are the opposite philosophy: simple, wired and dependable. They connect via USB Type A, so there's no pairing, no charging and no latency — you plug the 7.5 ft tangle-free TPE cable into your computer and you're live. A DAC digital decoder chip converts the digital signal for clean, high-fidelity audio, and the in-line controls handle volume, play/pause, recording and a mic mute (hold the multifunction button). For back-to-back Zoom calls, webinars and online classes, that mute button alone is worth a lot.
Comfort is clearly the design priority. The 45° in-ear ergonomic shape with a bud-style tip is meant to avoid the "squeezed" feeling cheaper computer earbuds cause after an hour, and the kit includes two pairs of replacement eartips, a cable clip and a mini storage bag. The 2.3 m cord lets you lean back or pace during a call, and the noise-isolating fit trims background chatter so your voice comes through clearly on the other end.
Buy it if you work or study at a PC or laptop all day, want a wired headset for meetings, classes or gaming chat, and value a physical mute button and cable length over wireless freedom. Skip it if you need Bluetooth, want an app or EQ, plan to sweat in them, or use a phone with no USB-A port. There's no waterproof rating here, so keep them desk-side.

If you're specifically hunting ear clip headphones for PC or waterproof open ear earbuds for PC, note that neither of these is an open-ear or ear-clip design — EarFun is a true-wireless in-ear and ASKUBSKU is a wired in-ear. If open-ear is a hard requirement, keep looking; if you just want the best ear clip headphones for PC style of convenience, the wired ASKUBSKU gets closest for desk work.
In my opinion, the EarFun Free 2S is the better buy for most people, because it does more jobs well — music, calls, workouts and travel — with app tuning, IPX7 protection and wireless convenience. But if your world is a desktop or laptop and your priority is a reliable wired in ear headset for PC with a working mute button, I'd pick the ASKUBSKU USB Earbuds without hesitation; they're the simpler, lower-fuss tool for that job. Buy the EarFun for flexibility, the ASKUBSKU for desk-side dependability. Either way, check the current price on Amazon before deciding.
Fit is everything. The ASKUBSKU set uses a 45° in-ear ergonomic shape and ships with two pairs of replacement eartips — try each size and pick the one that seals without pressure. A proper seal both holds the bud in place and improves noise isolation.
Sit the bud at the opening of your ear canal and gently rotate it inward until it feels seated, not jammed. The ASKUBSKU's angled 45° design is intended to follow the natural line of the ear canal, and the included cable clip keeps the cord from tugging the bud loose.
Use the right tip size, route the cable over your ear or clip it to your shirt, and avoid yanking the cord. Wired buds like the ASKUBSKU stay put better when the 7.5 ft cable is secured with the included clip; wireless sets depend more on tip fit alone.
Neither uses active noise cancellation. Both rely on sound isolation from the in-ear seal — the EarFun Free 2S also uses its four microphones to reduce background noise on calls, while the ASKUBSKU focuses on isolating noise so your voice is clearer in meetings.
