I’ve tested the QCY Crossky C30 earbuds for a week, and I’ve got mixed feelings about these clip-on wireless headphones.
Don’t get me wrong—they’re packed with features that make them stand out, but there are a few quirks that might give you pause.
Most importantly, if you’re hunting for budget-friendly clip-on earbuds that deliver solid performance for the price, these could very well be your next buddy.
Before you hit that “order” button, read on for my full experience with the Crossky C30, from design to sound quality and everything in between.

Unboxing: Simple but Sweet
The box is just like a typical QCY box. Inside, you get:
- The earbuds and a compact charging case
- A USB-C to USB-A cable
- A quick-start guide in English and Chinese

The case is super light at about 42g, with a single LED on the front and a USB-C port on the back. It’s not a fancy unboxing, but it gets the job done.
Honestly, for thirty bucks, I wasn’t expecting a red-carpet experience, and QCY delivers just enough to keep it practical.
Design and Feel
Let’s talk about how these earbuds feel. The C30s have this C-shaped clip-on design that’s honestly kinda dope.
They’re made with a flexible nickel-titanium alloy wrapped in soft, skin-friendly silicone, and each earbud weighs around 5g (I checked on my scale—closer to 5-6g).
They’re so light I barely notice them, even after hours of wear. The design has two “water-drop” modules: one sits near your ear canal to pump out sound, and the other hangs behind with the touch panel. They’re marked “L” and “R,” so no mixing them up like some other earbuds I’ve tried.

I’ve got average-sized ears, and these fit like a glove. The flexible bridge molds to your ear shape, whether you’ve got Dumbo flaps or tiny hamster ears (no judgment).
I wore them for runs, bike rides, and even some skateboarding, and they didn’t budge. Stress tests? Passed with flying colors—the hooks stay springy and don’t lose shape.
My only gripe is the IPX4 rating. It’s fine for light sweat or a drizzle, but if you’re a sweat machine like me, be careful. Those microphone ports and charging pins could get finicky if they get too wet.
Pro tip: wipe them down after a workout to keep the case’s connectors happy. For comfort and style, I’m giving these a solid 5/5—they’re a joy to wear.
Sound Quality
Now, the big question: how do these sound?
The C30s pack a 10.8mm dual-magnet dynamic driver, which QCY says delivers clear vocals. And you know what? They’re not wrong. For podcasts, audiobooks, and YouTube videos, these earbuds are chef’s kiss. Voices come through crisp and clean, with no distortion even when I crank the volume. I binged a true-crime podcast and felt like the host was right in the room with me.
Music, though? That’s where things get tricky. The open-ear design means bass takes a hit—sub-bass is basically nonexistent, and the low-end lacks that punchy rumble I crave for hip-hop or EDM. The mids are clean but a bit recessed, so vocals and instruments feel a tad distant.

The treble, on the other hand, is bright and detailed, which is great for clarity but can get sharp on vocals at high volumes. If you’re into a V-shaped sound with booming bass, these might leave you wanting.
The QCY app is a lifesaver here, though. It’s got six EQ presets and a 10-band equalizer, so I played around to boost the bass a bit. It helped, but don’t expect miracles—this is just how open-ear earbuds roll.
There’s also a spatial audio mode that adds a cool surround effect for movies and a game mode with 80ms latency for tight audio-video sync. For spoken word, I’d rate these 5/5. For music, a 2/5, unless you’re all about clarity over bass. They make me appreciate my in-ears more, but for casual listening, they get the job done.
Connectivity
With Bluetooth 5.4, the C30s connect like a dream, with a 10m range and dual-device pairing. I switched between my phone and laptop without a hitch, which is awesome for multitasking.
The QCY app shows battery levels, lets you update firmware, and even has a “find my earbuds” feature (a godsend for scatterbrains like me). I did hit a couple of connection glitches where one earbud dropped out, but popping them back in the case fixed it.

The 80ms game mode keeps audio synced for gaming or Netflix binges, which I loved. I’d rate connectivity a 4/5—super solid, but those rare dropouts keep it from perfection.
Controls
The touch controls on the C30s are a mixed bag. You get single, double, and triple taps for play/pause, skipping tracks, or adjusting volume, and the QCY app lets you customize them.
There’s even a touch sensitivity slider and a sleepy mode to disable touches when you’re napping (a lifesaver for me). But here’s the thing: the touch panels are tricky to find, and single taps often don’t register.

There’s also a slight delay, especially for volume changes, which got annoying fast. I ended up using my phone’s controls half the time. For controls, I’m giving these a 2/5—they’re functional, but not intuitive.
Microphones and Call Quality
The C30s have four mics (two per earbud) with ENC noise cancellation, and they impressed me. In a quiet room, my voice sounded clear and full, with no weird compression.
I recorded a test: “Mic check, testing one, two, three,” and it was like I was speaking face-to-face. In a noisy coffee shop (simulated with background noise), the mics did a great job picking up my voice while taming the chatter around me.
Wind noise crept in during a breezy walk, but callers said I still sounded clear, not robotic. For $32 earbuds, this is awesome—4/5, with a small ding for wind sensitivity.
Battery Life
QCY claims 5.5 hours per charge, with 25 hours total including the 400mAh case.
I put these to the test, and I actually got 6 hours, 11 minutes, and 9 seconds on a single charge—pretty sweet! The case adds another 19-20 hours, but compared to beasts like the QCY Crossky C30S (40 hours) or SoundPEATS PearlClip Pro (24-30 hours), it’s just okay.
The fast charging is clutch, though—10 minutes in the case gives you 3 hours of juice. I fell asleep with these a few times (thanks, sleepy mode), and they held up fine, but I wish the total battery life was beefier. I’m giving it a 3/5—good for daily use, but not a chart-topper.
Wrapping It Up
The QCY Crossky C30 earbuds are a budget-friendly win for anyone who wants comfort, affordability, and the ability to stay aware of their surroundings. They’re perfect for runners, cyclists, or anyone who loves podcasts and audiobooks on the go.
The lightweight design, secure fit, and QCY app’s customization options make these a joy to use, and the call quality punches above its weight.
But if you’re a bass head or want flawless touch controls, you might need to spend a bit more. For me, these are a niche hit—great for casual use or workouts, but not my go-to for music.
At $32, they’re hard to beat, and I’d recommend them to anyone looking for value without sacrificing style or comfort. Alternatively, you can check out 5 Top Clip-Style Earbuds Under $50.
