If you want a low-key semi-transparent design with a snug in-ear seal and a budget-friendly everyday listening experience, choose STUPIDYIN Earbuds; if you need an open-ear earhook fit that keeps you aware of your surroundings and a newer Bluetooth version for stable video and gaming sync, choose CCYLEZ Earbuds.
• STUPIDYIN biggest strength: Bluetooth 5.3 with instant pairing, 8mm dynamic drivers for punchy bass, and 30 hours of total playback in a semi-transparent white case.
• STUPIDYIN biggest trade-off: The in-ear design relies on passive noise cancellation only, so it physically blocks your ears and may not suit you if you need to stay aware of traffic or surroundings.
• CCYLEZ biggest strength: Open-ear earhook design with 180-degree rotating axes, so you can switch ears freely and stay aware of what's happening around you.
• CCYLEZ biggest trade-off: The open-ear shape means less passive isolation and a different sound-leakage trade-off, plus a shorter 90-day manufacturer warranty compared to STUPIDYIN's 1-year coverage.
• Who STUPIDYIN is for: Anyone who wants a discreet, sealed in-ear fit for music, calls and gym sessions.
• Who CCYLEZ is for: Runners, cyclists and outdoor workers who want ears-free awareness plus low-latency audio for video and gaming.
The STUPIDYIN TP10 leans into a clean, modern look. The semi-transparent white charging case has a shallow, matte translucent finish that lets you glimpse the earbuds inside — a subtle high-tech touch without being flashy. If you like gear that looks considered rather than loud, this is a design detail you'll actually notice every time you open the case.
On the audio side, the TP10 uses 8mm dynamic drivers with a frequency range of 20Hz to 20,000Hz and 32-ohm impedance. In my opinion, that combination is a sensible spec sheet for everyday listening: you get a wide soundstage with punchy bass and clear trebles, and the ergonomic in-ear fit naturally blocks out background noise. There's no active noise cancellation here — the noise control is passive, which means the seal itself does the work. That's fine for the gym or a commute, but it also means you're cutting yourself off from your surroundings.
Battery life is the quiet hero. You get up to 6 hours on a single charge, and the case pushes total playtime to 30 hours. Charging is handled over USB-C, which is the standard you already carry for everything else. The earbuds weigh just 0.12oz, and the bean-style shape sits flush against your ear for a visually discreet fit. IP54 waterproofing covers sweat and everyday moisture, so jogging and lifting are fair game. The controls are touch-based, and the package includes the case, cable, eartips and a user manual.
Who should buy it: Anyone who wants a sealed, discreet in-ear bud for music and calls, values long total playback, and prefers a modern semi-transparent case. It's also a natural fit if you want a straightforward Bluetooth 5.3 connection that pairs the moment you take the buds out.
Who should skip it: If you need to hear traffic, coworkers or your kids while wearing earbuds, the passive isolation works against you. And if you specifically want active noise cancellation, this isn't that product.
The CCYLEZ model takes a completely different approach. Instead of sealing into your ear canal, it uses an earhook shape with 180-degree rotating axes. That rotating design is genuinely practical: you can flip the hook to fit either ear without hunting for a left or right bud. In my opinion, that's a small feature that matters more than it sounds, especially if you're grabbing them one-handed before a run.
The open-ear design is the whole point. Sound is delivered into your ear while your canal stays open, so you keep awareness of your surroundings — traffic, other runners, announcements at the gym. The DT40 directional sound technology is claimed to reduce sound leakage by up to 99%, which addresses the usual complaint about open-ear buds broadcasting your podcast to everyone nearby. If you've avoided open-ear designs because of leakage, this is the feature to look at.
For calls, CCYLEZ leans on microphone noise cancellation to keep conversations clear, whether you're mid-workout or on a video call. There's also a smart chip tuned for low latency, which syncs audio to video — useful for gaming and watching content on your phone without that annoying lip-sync delay. Bluetooth 5.5 is the newer version here, and the 200mAh built-in battery supports around 30 hours of listening. The transmission distance is listed at 10 meters, and the supported protocols cover HSP 1.2, AVRCP 1.6 and D11.3.
One thing to weigh carefully: the warranty is a 90-day manufacturer warranty, which is shorter than STUPIDYIN's 1-year coverage. The material is PC and ABS, so it's a plastic build like most earbuds in this category.
Who should buy it: Runners, cyclists, walkers and anyone who wants music or calls without blocking their ears. It's also a good pick if low-latency video and gaming matter to you, or if you want the newer Bluetooth 5.5 standard.
Who should skip it: If you want deep bass isolation and a sealed fit that shuts out the world, the open-ear design is the opposite of that. And if you need active noise cancellation for flights, this isn't the tool.
• Best for battery life (total playback) → Both list around 30 hours of total playtime, so this is a tie on paper. STUPIDYIN splits it as 6 hours per charge plus case top-ups; CCYLEZ lists roughly 30 hours of listening from a 200mAh battery.
• Best for a sealed, immersive listen → STUPIDYIN Earbuds. The in-ear fit and 8mm dynamic drivers with passive noise cancellation block ambient sound for music and calls.
• Best for staying aware of your surroundings → CCYLEZ Earbuds. The open-ear design keeps your canal unobstructed for safety and awareness.
• Best for running and outdoor workouts → CCYLEZ Earbuds. The earhook with 180-degree rotating axes grips differently than a sealed bud and won't cut you off from traffic.
• Best for gym and sweat-heavy sessions → STUPIDYIN Earbuds. IP54 waterproofing and the flush bean-style fit make it a natural pick for lifting and jogging.
• Best for video, gaming and low latency → CCYLEZ Earbuds. The smart chip is explicitly tuned for synchronized audio and visuals.
• Best for call clarity in noisy places → CCYLEZ Earbuds. Microphone noise cancellation is a stated feature; STUPIDYIN relies on built-in mics with passive isolation.
• Best for a discreet, low-profile look → STUPIDYIN Earbuds. The semi-transparent case and flush fit disappear on your ear.
• Best for longer warranty coverage → STUPIDYIN Earbuds. It carries a 1-year manufacturer warranty versus CCYLEZ's 90 days.
• Best for budget-conscious buyers → Check the current price on Amazon for both. They sit in a similar everyday-bud bracket, and the deciding factor should be fit and use case, not a number I can quote here.
If I had to pick one, I'd buy the STUPIDYIN Earbuds. In my opinion, the combination of Bluetooth 5.3 instant pairing, 8mm dynamic drivers, IP54 sweat resistance, a flush in-ear fit and 30 hours of total playback covers the widest range of everyday scenarios — commuting, gym, calls and casual listening. The 1-year warranty also gives me more confidence than a 90-day one.
That said, I'd recommend the CCYLEZ Earbuds without hesitation for a runner or anyone who needs to hear the world while wearing earbuds. The rotating earhook and open-ear design solve a problem STUPIDYIN simply doesn't address, and the low-latency chip is a real advantage for mobile gaming and video.
FAQ
Not in the traditional sense. The open-ear design leaves your canal unobstructed, so you'll still hear your surroundings. The microphone noise cancellation is for calls, not for blocking ambient sound around you. If you want isolation, STUPIDYIN's in-ear passive noise cancellation is the closer match.
On paper they're close — both list around 30 hours of total listening. STUPIDYIN specifies up to 6 hours per charge with the case extending total playtime to 30 hours. CCYLEZ lists roughly 30 hours from its 200mAh built-in battery.
CCYLEZ is the stronger call pick because microphone noise cancellation is a core feature, and the low-latency chip helps with video calls. STUPIDYIN has built-in mics and relies on the in-ear seal to reduce background noise, which works well in quieter settings. Before deciding, check the current price on Amazon for both.
