How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want an open-ear fit that keeps your ears unblocked and your surroundings audible, choose Samudgate Headphones; if you need sealed in-ear buds with a charging case and a long total playtime, choose STUPIDYIN Earbuds.
• Samudgate Headphones – biggest strength: A true open-ear, earhook design at just 12.8g, so nothing sits inside your ear canal and you stay aware of traffic, teammates or your surroundings while you run.
• Samudgate Headphones – biggest trade-off: Being an open design, it doesn't physically seal your ear, so it relies on its noise-reduction mic rather than a passive seal to keep your calls clear in loud places. Playback is rated at 16 hours, all from the buds themselves.
• STUPIDYIN Earbuds – biggest strength: A sealed in-ear fit with 8mm dynamic drivers and up to 36 hours of total playback from a 500mAh charging case with a real-time LED power display.
• STUPIDYIN Earbuds – biggest trade-off: Because the buds sit inside your ear canal, they isolate you from your surroundings — great for focus, less ideal when you need to hear what's around you. Each bud is only 4g, but the seal is the whole point.
• Who each is for: Samudgate suits runners, walkers and anyone who wants an open, breathable, situational-awareness-first fit. STUPIDYIN suits commuters, travellers and home listeners who want punchy sealed audio and a case that tops the buds up on the go.
The Samudgate set is built around one idea: keep your ear canal open. Instead of pushing a tip into your ear, it hooks gently over the top of your ear and rests there, held by an ultra-soft silicone cushion. That's the whole reason the thing weighs just 12.8g — there's no sealed housing jammed against your ear. For long sessions, that's the appeal: it's lighter and more breathable than in-ear headphones, and the brand's own framing is that an open design can be gentler on your hearing than a tip pressed into the canal.
So who should buy it? Runners, walkers, gym-goers and cyclists — anyone who wants music but refuses to be deaf to the world. If you run on roads, share a trail, or work out in a busy gym and want to stay aware, the open fit is the feature, not a compromise. Who should skip it? If you want deep, isolating bass and a sealed, private listening bubble on a plane or a noisy train, an open design simply won't deliver that — the sound is there, but it isn't walled off from the room.
STUPIDYIN Earbuds: Who It's For
The STUPIDYIN S12 goes the opposite direction. These are conventional in-ear buds, and the fit is the point: each one weighs only 4 grams and sits snugly in your ear canal, creating a physical seal. That seal is what gives you passive noise isolation — no electronics required, just a physical block between you and the outside. The payoff is bass. With 8mm high-fidelity dynamic drivers and a 20Hz–20,000Hz frequency range, the S12 is tuned to push low-end weight and crisp treble, which is exactly what a sealed fit rewards.
Battery is the headline number here: up to 5 hours on a single charge, extended to 36 hours with the case. That case packs a 500mAh battery and — this is a genuinely useful touch — a large LED digital screen that shows the remaining power from 0 to 100% plus charging status for each bud. No guessing, no "is it dead or is it charging?" moments. Connectivity is Bluetooth 5.3 with auto-pairing: take them out of the case and they reconnect to your device in seconds, with near-zero latency for video. The matte finish is a small but real design choice too — it resists fingerprints in a way glossy plastic doesn't. IPX4 covers sweat and light rain, and it all ships with a cable, spare eartips, a manual and the charging case.
Buy these if you commute, travel, watch TV or laptop video, or want an immersive, isolated listen at home or in the gym. Skip them if situational awareness matters more than bass — a sealed canal is the last thing you want when you need to hear a car behind you.
Side-by-Side: Which Should You Choose?
• Best for total battery life → STUPIDYIN Earbuds. 36 hours with the case versus 16 hours on the Samudgate buds.
• Best for bass and immersive sound → STUPIDYIN Earbuds. 8mm dynamic drivers plus a physical seal for passive isolation.
• Best for long, breathable wear sessions → Samudgate Headphones. 12.8g and an open, non-sealing fit that won't plug your canal.
• Best for quick top-ups → Samudgate Headphones. A 15-minute charge is rated for 300 minutes of playback — handy if you forgot to charge overnight.
• Best for knowing your battery level → STUPIDYIN Earbuds. The case's LED display shows 0–100% plus per-bud charging status.
• Best for the latest Bluetooth and low video latency → STUPIDYIN Earbuds. Bluetooth 5.3 with auto-pairing and near-zero latency, versus Bluetooth 5.2 on the Samudgate.
• Best for clear calls in a noisy room → Samudgate Headphones. Its noise-reduction mic is designed to pull your voice forward and cut surrounding noise.
If I had to pick one, I'd take the STUPIDYIN Earbuds — but only because of what I'd use them for. In my opinion, the combination of a sealed in-ear fit, 8mm drivers, 36 hours of total playback and a case that actually tells you its battery level makes the S12 the more versatile everyday pair for commuting, travel and video. That said, I'd recommend the Samudgate Headphones without hesitation to any runner, walker or cyclist who values hearing the world around them over bass. The right answer is really about your ears and your commute: sealed and immersive, or open and aware. Check the current price on Amazon for both before you commit.
For running, yes — in my opinion the Samudgate's open earhook fit is the better match. It weighs 12.8g, sits over the ear rather than inside it, and keeps you aware of traffic. The STUPIDYIN is IPX4 too, but its sealed in-ear design blocks your surroundings.
On the numbers, yes. The STUPIDYIN is rated at up to 5 hours per charge and 36 hours total with its 500mAh case, while the Samudgate is rated at 16 hours of playback. If you want the longest total runtime, the S12 wins.
The Samudgate Headphones have a dedicated noise-reduction microphone designed to reduce surrounding noise so your voice comes through clearly, even in a noisy place. The STUPIDYIN relies on its in-ear seal and passive isolation rather than a noise-reduction mic for calls.
Yes. The S12 ships with a wireless charging case that holds a 500mAh battery and features an LED display showing remaining power from 0–100% plus per-bud charging status. The Samudgate Headphones are charged via a cable and don't use a case.
