How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a pair of wired earbuds that plug straight into a modern USB-C phone and stay pocket-sized, choose ASKUBSKU USB C Headphones; if you need over-ear studio headphones for DJing, mixing, recording or playing an instrument, choose OneOdio A71D.
• ASKUBSKU USB C Headphones — biggest strength: a Type-C plug with a built-in DAC decoder chip, so it works with a huge list of USB-C phones, tablets and laptops without a dongle.
• ASKUBSKU USB C Headphones — biggest trade-off: it is a small semi in-ear earbud with a 3.9-foot cable and button controls only, so there is no 6.35 mm adapter for amps or mixers and no over-ear isolation.
• OneOdio A71D — biggest strength: 40 mm drivers, a 20 Hz–40 kHz frequency response, 90° swiveling ear cups for single-ear monitoring and a 2.2 m cable with a 3.5 mm-to-6.35 mm adapter.
• OneOdio A71D — biggest trade-off: it is a full over-ear headphone built around a 3.5 mm jack, so it is not the thing you tuck into a pocket or plug into a USB-C-only phone without an adapter.
• Who each pick is for: ASKUBSKU for phone-first listeners who want a cable and a mic; OneOdio A71D for musicians, DJs and home-studio users who need to plug into gear.
The ASKUBSKU USB C Headphones are built around one problem: modern phones dropped the headphone jack, and you still want a wire. The answer here is a Type-C connector with a Hi-Res and DAC digital decoder chip inside, which converts the digital signal on the way in rather than relying on the phone to do the work. In plain terms, that is the part that makes a USB-C earbud actually sound like something. The listed audio specs back it up on paper: 32 ohm impedance, 115 dB sensitivity, a dynamic driver and a 20 Hz–20 kHz frequency range. High sensitivity and low-ish impedance usually means easy to drive — you should not need a separate amp.
The compatibility list is the headline feature, and it is genuinely long: recent Samsung Galaxy S and Note models, Z Fold and Z Flip, Google Pixel, OnePlus, Huawei, Sony Xperia, plus iPhone 15 and later, iPad and MacBook. If your device has a USB-C port and no headphone jack, this is the shape of product that fits it.
Who should buy it: anyone whose phone, tablet or laptop is USB-C only and who wants a lightweight, wired, mic-equipped earbud for calls, commuting, running, gym work and general listening. The spec sheet explicitly frames it around running, jogging, weight lifting, walking and hiking, which matches the semi in-ear fit and light weight (1.44 ounces).
Who should skip it: if you need to plug into a mixer, amp, guitar, keyboard or audio interface, this is the wrong connector. There is no 6.35 mm plug and no adapter in the box. Skip it too if you want over-ear isolation or a long cable for moving around a room.
OneOdio A71D: Who It's For
The OneOdio A71D sits in a completely different category. This is a wired over-ear studio monitor headphone with 40 mm dynamic drivers, 32 ohm impedance, 110 dB sensitivity and a frequency response that reaches 40 kHz — the top end of that range is the "Hi-Res" claim in the product name, and it is a spec aimed at people who care about detail in the upper frequencies, not just bass.
The feature that tells you what this product is really for is the 90° swiveling ear cups. That is a single-sided monitoring design: you rotate one cup back so one ear is on the music and the other is on the room. DJs do this to cue a track while hearing the crowd; producers and engineers do it to check a mix against the room. If you have never needed that, you probably are not the target buyer — but if you have, you know exactly why it matters.
The rest of the package points the same direction. The cable is a fixed 2.2 m (7.2 ft) run, long enough to reach from your head to a mixer, amp, PC, laptop, guitar or keyboard without yanking. A 3.5 mm to 6.35 mm adapter is included, which is the standard way to move between consumer gear and pro audio equipment. Comfort is handled with soft padded ear muffs and an adjustable headband, and the whole thing folds for transport. Enclosure materials are a mix of soft padding and a durable outer shell, and it carries a one-year warranty.
Who should buy it: DJs, musicians, podcasters, producers, home-studio users, and anyone who wants over-ear isolation while working at a desk or playing an instrument. The 6.35 mm adapter and the long cable are the two details that make it practical for real gear.
Side-by-Side: Which Should You Choose?
• Best for USB-C phones with no headphone jack → ASKUBSKU USB C Headphones. The Type-C plug and DAC chip are the entire point.
• Best for DJing, mixing and single-ear monitoring → OneOdio A71D. The 90° swiveling cups are built for it.
• Best for plugging into an amp, mixer, guitar or keyboard → OneOdio A71D. The 3.5 mm jack plus the included 6.35 mm adapter covers pro gear.
• Best for calls and hands-free use → ASKUBSKU USB C Headphones. Built-in mic plus in-line answer/reject and volume buttons.
• Best for long cable reach across a desk or studio → OneOdio A71D. 2.2 m (7.2 ft) versus 3.9 ft.
• Best for portability and pocket carry → ASKUBSKU USB C Headphones. Semi in-ear, 1.44 ounces, magnetic earbuds, carry bag included.
• Best for over-ear comfort and isolation during long sessions → OneOdio A71D. Padded muffs, adjustable headband, 40 mm drivers.
• Best for extended high-frequency detail on paper → OneOdio A71D. 20 Hz–40 kHz versus 20 Hz–20 kHz.
In my opinion, these two are not really competitors — they solve different problems, and the right answer depends on what you are plugging into. If I had a USB-C phone and wanted one wired pair for calls, walks and workouts, I would buy the ASKUBSKU USB C Headphones, because the Type-C connector and DAC chip mean it just works without a dongle. If I were setting up at a desk, a mixer or a stage, I would buy the OneOdio A71D, because the swiveling cups, long cable and 6.35 mm adapter are the features that actually matter there. Buy for the socket you own, not the spec sheet you admire.
A wired headphone sends the audio signal from your device down a cable to the drivers in the earcups or earbuds, which convert the electrical signal into sound. The ASKUBSKU USB C Headphones take a digital signal over USB-C and convert it internally with a DAC chip, while the OneOdio A71D takes a standard analog signal through its 3.5 mm jack and 6.35 mm adapter.
You need a connector that matches your iPhone's port. The ASKUBSKU USB C Headphones list iPhone 15 and later models, which use USB-C, so they plug straight in. Older iPhones with Lightning need a Lightning-to-3.5 mm adapter for the OneOdio A71D, since that headphone ends in a 3.5 mm plug.
Start with the connection: unplug and reseat the cable, and confirm you are using the correct port or adapter — a 3.5 mm plug into a USB-C phone, for example, will not work without an adapter. Check that the in-line controls are not paused and that the correct output device is selected in your settings. If one side still fails, the cable or driver is likely damaged, and the OneOdio A71D's one-year warranty is worth checking.
It depends on what you already own. If your phone is USB-C only and you want a mic and controls, the ASKUBSKU USB C Headphones give you the connector you need with no extra parts. If you need to plug into an amp, mixer or instrument, the OneOdio A71D's 40 mm drivers, swiveling cups and included 6.35 mm adapter do more of the work. Check the current price on Amazon for both before deciding.
