• ASKUBSKU's biggest strength: a built-in mic plus remote volume control, a 45° ergonomic in-ear shape, and a lightweight, portable build that comes with a carry bag.
• ASKUBSKU's biggest trade-off: the connector and cable hardware are described in simpler terms than FIYUM's, with no aluminum alloy connector or twist-resistant cable called out in the specs.
• FIYUM's biggest strength: it's positioned around iPhone 15/16/17 compatibility and uses a DAC chip for HiFi stereo sound, with a TPE twist-resistant cable and aluminum alloy USB-C connector.
• FIYUM's biggest trade-off: there's no carry pouch in the box, and the emphasis is squarely on iPhone and USB-C device compatibility rather than a broader multi-brand accessory story.
• Who ASKUBSKU is for: shoppers who want a simple, lightweight wired USB-C earphone with mic and inline controls for commuting, shopping, running and similar daily use.
• Who FIYUM is for: iPhone 15/16/17 owners and USB-C device users who care most about sound processing, a durable cable and connector, and a warranty-backed purchase.
ASKUBSKU's pitch is straightforward: a wired USB-C in-ear earphone with a built-in microphone and a remote that handles volume, call pickup/hang-up and track skipping. If you've ever fumbled for your phone mid-commute just to nudge the volume, that remote is the practical reason to look here. The listed design leans on a 45° in-ear ergonomic angle meant to reduce pain and fatigue over long wear, and the whole thing is described as lightweight and portable — the kind of earphone you leave in a bag and forget about until you need it.
The spec sheet keeps things simple and functional. You get a plastic enclosure in silver, a dynamic driver covering the standard 20 Hz – 20,000 Hz range, sound isolation as the noise-control approach, and a carry bag in the box (black or gray). The connector is USB-C and the connection is fully wired, so there's no pairing, no charging, no battery anxiety. It's aimed at adults and sold as a single item.
Who should buy it: someone who wants an uncomplicated wired USB-C earphone for shopping, bus rides, running, climbing or general "music anywhere" use, and who values having volume and call controls right on the cord. Who should skip it: if your priority is a DAC-driven sound stage, a metal connector, or a stated manufacturer warranty, ASKUBSKU doesn't advertise those things — FIYUM does. Also skip it if you specifically want a non-USB-C connection; this is USB-C only.
FIYUM frames its USB-C earphones around the newest iPhones, calling out iPhone 17, 16 and 15 Pro Max directly, and extending compatibility to Samsung Galaxy S24/S23, Google Pixel and iPad Pro. That's the headline: a wired USB-C earphone for people who've moved to a USB-C iPhone and don't want to think about adapters. It's also labeled as MFi Certified in the product title, which matters if you're specifically shopping for a wired set for an iPhone 15/16/17.
The audio story is the second pillar. FIYUM builds in a DAC chip and describes the result as HiFi stereo with lossless-leaning detail — deep bass to crisp highs. Whether you're a casual listener or someone who wants more out of a wired connection than a bare-bones dongle setup, that's the design intent. On the hardware side, the cable is TPE and twist-resistant to fight tangling, and the USB-C connectors are aluminum alloy for durability and corrosion resistance. The earpieces are in-ear with rounded tips, the enclosure is TPE, and the color is white. There's a built-in mic and remote control, sound isolation, and a one-year manufacturer warranty. Buyers include adults, teens and youth.
Who should buy it: iPhone 15/16/17 owners, USB-C Android and Pixel users, and anyone who switches between devices and wants one wired set that travels well and resists cable damage. Who should skip it: if you want a carry pouch included or you prefer a lightweight, minimal accessory set, ASKUBSKU covers that better. FIYUM is the more feature-dense, iPhone-forward pick.
Side-by-Side: Which Should You Choose?
• Best for sound processing → FIYUM Earphones USB C. The DAC chip and HiFi stereo claim are the core of its audio pitch; ASKUBSKU lists a dynamic driver and a 20 Hz–20,000 Hz range without a DAC.
• Best for cable and connector durability → FIYUM Earphones USB C. TPE twist-resistant cable plus aluminum alloy USB-C connectors are called out; ASKUBSKU doesn't advertise those materials.
• Best for inline controls → ASKUBSKU USB C Earbuds. Mic, remote volume, call pickup/hang-up and track skipping are all listed as built in.
• Best for long-wear comfort design → ASKUBSKU USB C Earbuds. The 45° in-ear ergonomic angle is specifically described as reducing pain and fatigue.
• Best for portability extras → ASKUBSKU USB C Earbuds. A carry bag is included; FIYUM doesn't list one.
• Best for warranty coverage → FIYUM Earphones USB C. A one-year manufacturer warranty is stated; ASKUBSKU lists none.
• Best for a simple, no-frills wired set → ASKUBSKU USB C Earbuds. One item, wired USB-C, lightweight, sound isolation, done.
In my opinion, if you own an iPhone 15, 16 or 17 — or you're buying wired headphones for an iPhone and want the safest spec match — the FIYUM Earphones USB C is the one I'd pick. The DAC chip, MFi-certified iPhone framing, aluminum alloy connectors, twist-resistant TPE cable and one-year warranty make it the more future-proof, better-protected purchase. I'd choose the ASKUBSKU USB C Earbuds instead if inline volume control, a 45° comfort-focused fit and an included carry bag matter more to you than DAC processing and metal hardware. Either way, check the current price on Amazon before you commit, since it moves around.
FAQ

how to use wired headphones for iphone 15
The iPhone 15 series moved to USB-C, so a USB-C wired earphone plugs directly into the bottom port with no adapter needed. FIYUM lists iPhone 15 Pro Max support and MFi certification, and ASKUBSKU lists iPhone 15 Pro Max Plus among its compatible devices. Plug in, then use the remote for volume and calls.
how to use wired headphones for iphone
On any USB-C iPhone, plug the earphone's USB-C connector into the charging port and audio routes automatically — no settings to change. Both picks here are wired USB-C with a built-in mic and remote, so calls and volume work from the cord. If you're on an older Lightning iPhone, neither of these will fit without an adapter.

The iPhone 16 uses the same USB-C port as the 15, so you connect the earphone the same way: straight into the bottom port. FIYUM names iPhone 16 in its compatibility list and includes a DAC chip for its HiFi stereo sound, while ASKUBSKU lists iPhone 16 among its supported devices. Once plugged in, the remote handles volume, call pickup/hang-up and track skipping.
