How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a wired USB-C in-ear monitor with real acoustic engineering, app-based tuning and a replaceable cable, choose Moondrop CHU II DSP; if you need a bulk pack of on-ear USB-C headphones to hand out to a classroom, a testing room or a team, choose GDBOMA USB C Headphones.
• Moondrop CHU II DSP — biggest strength: genuine IEM design — a 10 mm dynamic driver with an aluminum-magnesium alloy dome diaphragm, a brass CNC acoustic nozzle, an alloy-cast cavity and three bass presets you switch in the Moondrop Link app.
• Moondrop CHU II DSP — biggest trade-off: it's a single set of in-ear monitors for one listener, it's wired-only (no Bluetooth), and it needs you to actually care about fit and tuning to get your money's worth.
• GDBOMA USB C Headphones — biggest strength: it's a 10-pack of wired USB-C on-ear headphones in mixed colors, which solves the "everyone needs a headset right now" problem in one go.
• GDBOMA USB C Headphones — biggest trade-off: 32 ohm on-ear units with fabric earpads and passive noise cancellation — built for clear speech and durability across many users, not for music listening.
• Who each is for: pick Moondrop if you're one person who wants better sound from a USB-C device; pick GDBOMA if you're equipping a group.
The CHU II DSP is the "audio first" pick of these two. The 10 mm dynamic driver uses an aluminum-magnesium alloy dome composite diaphragm — a material choice Moondrop reserves for higher-end models because it's stiff and light at the same time. In plain terms, that's a design intended to extend the treble bandwidth and pull out small details in a recording. The frequency range is quoted at 15 Hz to 38 kHz, impedance is 18 ohm and sensitivity is 119 dB, which tells you it's an easy load for a phone, tablet or laptop's USB-C port.
Two details stand out to me as a buyer. First, the brass CNC acoustic nozzle is a separate machined component rather than part of the shell, which is the kind of construction you normally associate with pricier IEMs. Second, the DSP part is real: the CHU II DSP has three bass presets built in, switchable through the Moondrop Link app, so you can nudge the low end toward your taste without touching an equalizer. The alloy-cast cavity is finished with a protective paint layer to resist corrosion, and it ships with a leather case, three sizes of ear tips, a wearing card, a certificate and a manual.
Who should buy it? Someone who listens on a USB-C phone, a laptop or a dongle-free setup and wants in-ear monitors rather than a headset. The 0.78 mm interchangeable cable is the sleeper feature — you can swap cables, or move to a Bluetooth neckband or TWS ear-hooks when you want wireless, which stretches one purchase across several use cases. Controls are touch-based on the earpieces, and there's no active noise cancellation.
Who should skip it? Anyone who needs multiple headphones, or who wants over-ear comfort for all-day calls. It's a single set of IEMs for one owner, and the in-ear, rounded-tip fit is a personal thing — if you dislike things sitting in your ear canal, this isn't the shape for you.
The GDBOMA set is a completely different product that happens to share the USB-C plug. It's a bulk 10-pack of wired on-ear headphones in mixed colors, model GDB381, with 32 ohm impedance and fabric earpads. The over-ear, on-ear design sits against the ear rather than inside it, and it uses passive noise cancellation — meaning the physical seal and padding reduce some surrounding noise, with no electronics or battery involved. There's no Bluetooth, no app, and no tuning presets. What you plug into a USB-C port is what you get.
That's not a weakness in the context this product was built for. Ten pairs in one box means a school, a classroom, a practice-test session, an online class, a web conference or a meeting room can equip everyone at once, in mixed colors that make it easy to tell whose pair is whose. The fabric enclosure is a sensible choice for shared, repeatedly handled gear, and the age range covers kids, teens and adults. There's a 1-year warranty and the package includes the cable.
Who should buy it? Anyone buying for a group: teachers, test coordinators, IT people kitting out a lab, parents splitting a pack between siblings. If your priority is "everyone has a working USB-C headset and nobody cries over whose is whose," this is the practical answer.
Who should skip it? Anyone buying for themselves for music. A 32 ohm on-ear with fabric pads and passive isolation is tuned for speech intelligibility and durability, not for detail retrieval or bass extension. If you want one good pair for listening, this isn't it.
• Best for sound quality → Moondrop CHU II DSP. Alloy-dome dynamic driver, brass CNC nozzle, alloy-cast cavity, 15 Hz–38 kHz range.
• Best for tuning flexibility → Moondrop CHU II DSP. Three bass presets switched in the Moondrop Link app.
• Best for equipping a group → GDBOMA USB C Headphones. Ten wired USB-C on-ear units in mixed colors, one box.
• Best for classroom, testing or meeting-room use → GDBOMA USB C Headphones. Mixed colors, fabric build, on-ear fit that doesn't require each user to seat an ear tip correctly.
• Best for cable longevity and future-proofing → Moondrop CHU II DSP. 0.78 mm interchangeable cable, plus optional Bluetooth neckband or TWS ear-hook use.
• Best for isolation without electronics → GDBOMA USB C Headphones. Passive noise cancellation from the on-ear padding.
• Best for travel and daily carry → Moondrop CHU II DSP. In-ear size, leather case included, and a cable you can replace if it fails.
• Best for an all-day call headset for one person → neither, honestly. Moondrop is in-ear with no active noise cancellation; GDBOMA is built for many users rather than long solo sessions.
In my opinion, most people reading a USB-C headphone comparison are buying for themselves, and for that buyer I'd take the Moondrop CHU II DSP. The driver material, the machined brass nozzle, the cast alloy shell, the app-switchable bass presets and the swappable 0.78 mm cable are all things I can point to in the spec sheet and explain — they're design decisions that show up as sound. The GDBOMA pack is the better tool for a specific job, and if that job is yours, buy it without hesitation. But as a personal pair of USB-C headphones in 2026, the Moondrop is the one I'd plug in. Check the current price on Amazon before you decide, since that's the one thing that can flip this either way.
how to use usb c headphones on mac
Plug the USB-C connector into a USB-C port on your Mac. macOS routes audio to it automatically, and you can confirm or switch the output in System Settings under Sound. Both the Moondrop CHU II DSP and the GDBOMA GDB381 are wired USB-C, so no adapter or pairing is needed.
how to use usb c headphones on android phone
Connect the USB-C plug to your phone's USB-C port. Android detects wired USB-C audio and sends sound to it, usually without any setup. If your phone has a case that blocks the port, remove the case first. The CHU II DSP adds one extra step: the Moondrop Link app, which is where you switch between its three bass presets.
how to use usb c headphones on android
Same idea on tablets and Android devices generally — plug in, and the device treats the headphones as the audio output. If sound keeps coming from the speaker, check your sound settings for a USB audio option. On the Moondrop CHU II DSP, the touch controls on the earpieces handle playback, and the GDBOMA set uses the inline cable.
how to use usb c headphones on ps5
The PS5 has a USB-C port, and wired USB-C headsets can be selected as the audio output in the console's sound settings. Set the output device to the USB headset, then set the microphone input the same way. The Moondrop CHU II DSP includes a microphone and touch controls; the GDBOMA GDB381 is a straightforward wired option for voice chat.
