If you want a wired USB-C earphone built for long, focused listening sessions in a library — with a braided anti-tangle cable, a storage case, a cable clip, and three eartip sizes for a locked-in fit — choose ACAGET USB C Earbuds; if you need a 90° right-angle plug that clears the edge of an iPad or a phone in a thick case, choose ASKUBSKU 90°.
• ACAGET — biggest strength: the most complete "sit down and listen" package here: 13 mm dynamic drivers, a braided nylon cable that resists aging, three eartip sizes (S/M/L), a cable clip, a storage case, and magnets to keep the buds together.
• ACAGET — biggest trade-off: it's a straight-plug, sound-isolation design, so it's built for one person in a quiet seat rather than for plugging into a tablet propped up sideways.
• ASKUBSKU 90° — biggest strength: that 90° right-angle USB-C connector, plus the broadest compatibility list of the two, reaching across Samsung Galaxy S and Z lines, iPhone 15 through 17, iPad, iPad Pro, iPad Air, iPad Mini, and MacBook.
• ASKUBSKU 90° — biggest trade-off: a leaner accessory bundle — ear cushions and a protective case — with no cable clip, no braided-cable claim, and no multiple eartip sizes mentioned.
• For library use → ACAGET USB C Earbuds, if quiet, tangle-free, all-day comfort is the goal.
• For sideways devices and mixed gadgets → ASKUBSKU 90°.
• Who each is for: ACAGET suits students, readers and commuters who want a sealed, organized listening kit; ASKUBSKU suits tablet and laptop users who hate a straight plug digging into their hand.
The ACAGET USB C Earbuds are the more "kit-like" of the two. The brand ships them with three eartip sizes, a cable clip and a storage case, and the description notes the S/M/L silicone buds are meant to give a solid fit even in small ears. For a library, that matters more than it sounds: a good seal is what lets sound isolation actually do its job, so you hear your own audio instead of the page-turner two tables over — and you keep your volume lower in the process.
On the audio side, ACAGET lists a 13 mm dynamic driver, a 20 Hz–20,000 Hz frequency range, 32 ohm impedance and 105 dB sensitivity. In plain terms, that's a reasonably sensitive, easy-to-drive in-ear, which is exactly what you want from a wired USB-C set plugged straight into a phone or laptop — no amp, no fuss. ACAGET describes the tuning as high-fidelity with deep bass and clear vocals, aimed at music lovers and gamers. I'd read that as a warm, consumer-friendly sound rather than a flat studio monitor, and the 13 mm driver size is consistent with that.
The physical design is clearly aimed at daily carry. The cable is braided nylon, which ACAGET says prevents aging for a longer lifespan, and the buds are magnetic so they snap together instead of swinging around. The shell is ABS with metal-plated accents in a black-red gradient — a look, not a spec, but it does signal that ACAGET expects these to be seen. In-line volume controls and a built-in HD mic handle calls and voice assistants, and ACAGET adds sweat and water resistance.
Buy ACAGET if you want a wired USB-C earphone for headphones-for-library duty: long reading or study blocks, minimal tangling, a case to throw in a bag, and a fit you can tune with three tip sizes. Skip it if you mainly plug into a tablet held in landscape or a phone in a chunky case, where a straight plug tends to get in the way — that's the ASKUBSKU's territory.
The ASKUBSKU 90° leads with an ergonomic idea rather than an accessory bundle. Its headline feature is the right-angle USB-C plug, which turns the cable 90 degrees at the connector so it runs flat along the edge of your device instead of sticking straight out. If you've ever tried to hold an iPad or a phone in landscape with a straight-plug earphone, you already know why that matters — the plug presses into your palm, and the cable bends at the worst possible angle.
The compatibility list is the other half of the pitch, and it's genuinely long. ASKUBSKU names Samsung Galaxy S20 through S25 families, the S23 FE, Note 10 and Note 20 lines, Tab S8/S9/S10 tablets, Z Flip and Z Fold 3 through 7, iPhone 15 through 17 (including Pro Max and the 16e), iPad 10th and 11th gen, iPad Pro, iPad Air, iPad Mini 6 and 7, and MacBook, MacBook Pro and MacBook Air. That's a set you can move between a phone, a tablet and a laptop without thinking about which cable goes with which device.
Audio-wise, ASKUBSKU lists a dynamic driver and a 20 Hz–20,000 Hz frequency range — the same standard full-range window as the ACAGET — and describes the tuning as HiFi stereo. The earbuds are semi-in-ear with a white plastic shell, they use sound isolation for noise control, and the buds are magnetic. Controls are button-based and in-line: a built-in mic for calls, plus volume adjustment and track skipping, which ASKUBSKU says keeps call interference down. In the box you get ear cushions and a protective case.
Buy ASKUBSKU if you want a wireless-headphones-for-library replacement that plugs into a tablet or laptop without fouling your grip, and you value one cable covering a drawer full of USB-C gadgets. Skip it if you want a tuned ear-tip fit and a braided cable with a clip — ASKUBSKU doesn't list multiple eartip sizes or a braided cable, so the ACAGET has the edge on fit and cable longevity.
Side-by-Side: Which Should You Choose?
• Best for tablet and laptop use → ASKUBSKU 90°. The right-angle plug keeps the cable clear of your hand on a landscape iPad or MacBook.
• Best for cable durability → ACAGET USB C Earbuds. Braided nylon is explicitly claimed to resist aging; ASKUBSKU doesn't make a braided-cable claim.
• Best for tangle-free storage → ACAGET USB C Earbuds. Magnetic buds, a cable clip and a storage case are all listed; ASKUBSKU lists a protective case and ear cushions only.
• Best for device coverage → ASKUBSKU 90°. Its compatibility list spans Galaxy S/Z/Tab, iPhone 15–17, iPad, iPad Pro, iPad Air, iPad Mini and MacBook.
• Best fit flexibility → ACAGET USB C Earbuds, thanks to the S/M/L eartip sizes — useful if standard tips never quite seal for you.
• Best for calls and quick controls → a near tie. Both have an in-line mic and button controls; ACAGET lists a dedicated volume control and remote, ASKUBSKU lists volume plus track skipping.
• Best for active, sweaty use → ACAGET USB C Earbuds, which are listed as sweat and water resistant. ASKUBSKU doesn't make that claim.
• Best gaming headset for library sessions → ACAGET USB C Earbuds, on the strength of its 13 mm dynamic driver and the deep-bass, immersive tuning ACAGET describes.
For library use, I'd buy the ACAGET USB C Earbuds. The three eartip sizes, sound isolation, braided cable, magnetic buds, cable clip and storage case all point at the same job: focused, quiet, organized listening you can do for hours without fiddling. The 13 mm dynamic driver and 32 ohm impedance make it an easy, full-sounding match for a phone or laptop headphone jack. The ASKUBSKU 90° is the smarter pick if your device lives in landscape or you're juggling several USB-C gadgets — that right-angle plug and its compatibility list are real advantages. But if the library is the main venue, ACAGET is the one I'd hand you.
what hifi wireless earbuds — Both of these are actually wired USB-C earphones, not wireless, so neither pairs over Bluetooth. "HiFi" here refers to the sound claim: ACAGET describes high-fidelity audio with deep bass and clear vocals, and ASKUBSKU describes HiFi stereo, with both using a dynamic driver and a 20 Hz–20,000 Hz range. If you specifically need wireless, neither is the right product.
what are the best hifi wireless earbuds — I can't rank wireless earbuds from these data sheets, since both products here are wired. If your "wireless" requirement is really about convenience, the practical answer is which wired pair suits your device: the ASKUBSKU 90° for tablets, laptops and a wide spread of USB-C gadgets, the ACAGET for a sealed, tangle-free, case-and-clip kit. Check the current price on Amazon before deciding.
Are these two earbuds compatible with the same phones?
— Largely, yes. ASKUBSKU publishes the longer list, naming Galaxy S20–S25, Note 10/20, Z Flip and Z Fold, iPhone 15–17, iPad, iPad Pro, iPad Air, iPad Mini and MacBook. ACAGET targets Galaxy S21–S26 and iPhone 16/17 Pro Max families plus Android USB-C devices. Both need a USB-C port — neither works with a 3.5 mm jack.
— In my opinion, the ACAGET USB C Earbuds, because the three eartip sizes and sound isolation let you get a proper seal, and the magnetic buds, cable clip and storage case keep everything quiet and untangled in a bag. The ASKUBSKU 90° is the better call if you mostly listen on a tablet or laptop held sideways.
