Innate Devices CY-1

The Innate Devices Guardian CY-1 is a budget earplug headphone hybrid that delivers OSHA-compliant hearing protection with decent audio for around $20 USD. It's comfortable enough for all-day wear and works great in moderate noise environments like workshops and motorcycle rides. Just don't expect great sound quality, a microphone, or long-term durability.

Let's be honest about what these are. The sound quality sits at the 53rd percentile in our database, which means it's fine but nothing to write home about. You're not getting deep, rumbling bass or sparkling highs. What you get is clear, intelligible audio that cuts through the noise around you. For a job site or a motorcycle helmet, that's exactly what you need. Podcasts sound great. Music sounds decent. Audiophile-grade? Not even close.

The noise reduction is where this product earns its keep. The ANC score lands at the 74th percentile, which is impressive for something that doesn't actually have active noise cancellation. It's all passive isolation from the earplug design. In moderate environments like a workshop or a busy warehouse, it does a solid job. But if you're running a jackhammer or standing next to a jet engine, users report it's not enough. The foam tips are the key. Swap to silicone and you lose a noticeable chunk of that protection.

One thing to note: there's no microphone and no volume control on the cable. That mic score of 11th percentile isn't a typo. If you need to take calls while wearing these, you're out of luck. This is a one-way audio device, and that's fine for the intended use case.

Stacked against the JLab JBuds Pods ANC, the Guardian wins on hearing protection but loses on basically everything else. The JBuds have real ANC, wireless connectivity, and a mic for calls. But they're not OSHA-compliant earplugs, and they cost more. If you're in a loud industrial setting, the Guardian is the safer choice. If you're commuting on a train, get the JBuds.

The Soundcore P31i and EarFun Air Pro TW230B are both true wireless earbuds with better sound and more features. But again, none of them are designed to protect your hearing in a factory. The Baseus Bass BP1 Pro is closer in spirit, a budget wired option, but it doesn't have the earplug design or the NRR rating. For motorcycle riders specifically, the Guardian's low-profile fit under a helmet is a huge advantage that none of these competitors can match. The wired connection also means no battery anxiety on long rides.

At $20 USD, the Guardian CY-1 is hard to beat if you need hearing protection with audio. Most dedicated earplug headphones from bigger brands cost two or three times as much. You're getting a complete kit with foam tips, silicone tips, a waterproof case, and a cable clip. The 90-day warranty is short, but at this price, you could buy a backup pair and still come out ahead. Compared to something like the JLab JBuds Pods ANC or the Anker Space A40, you're trading wireless convenience and better sound for serious cost savings and actual OSHA-rated protection. For a work environment, that's a trade worth making.

The Innate Devices Guardian CY-1, better known as the Plugfones Guardian, is a weird little hybrid that sits somewhere between a pair of foam earplugs and a set of wired earbuds. It's built for people who need hearing protection but still want to listen to music or podcasts while they work. At around $20 USD, it's one of the cheapest ways to get OSHA-compliant noise reduction with actual audio drivers baked in. The pitch is simple: block out the dangerous stuff, keep the good stuff. And for the most part, it works.

If you're searching for earplug headphones for construction, motorcycle riding, or warehouse work, this thing keeps popping up. It's wired, which feels almost retro in 2025, but that's kind of the point. No batteries to charge, no Bluetooth dropouts, no latency. Just plug it into your phone or radio and go. The 23g weight is light enough that you'll forget they're in after a while, which matters when you're wearing them for a full shift.

The Guardian comes with two sets of tips: foam and silicone. The foam tips are the stars here, giving you that 27-29dB NRR rating depending on which documentation you trust. The silicone tips are more comfortable for some people but don't block as much noise. Either way, you're getting real hearing protection, not just passive isolation from a rubber gasket.

Skip the Guardian CY-1 if you need earbuds for calls, music quality, or everyday commuting. The lack of a microphone is a dealbreaker for anyone who takes calls on the go, and the sound quality won't impress anyone used to even budget true wireless earbuds. If you work in extremely loud environments like airports or heavy demolition, the noise reduction won't be enough and you should look at dedicated earmuff-style protection with higher NRR ratings. And if you're rough on your gear, the documented durability issues with foam tips and the audio jack mean these might not survive your daily grind. For general listening, grab the Soundcore P31i or EarFun Air Pro TW230B instead. For serious hearing protection with audio, you'll need to spend more on something built tougher.

Should you buy the Innate Devices Guardian CY-1? If you work in a noisy environment and want to listen to audio without destroying your hearing, yes. It's cheap, comfortable, and does exactly what it claims. The noise reduction is real, the fit is secure, and the wired design means it just works when you plug it in.

But if you're looking for everyday earbuds for music or calls, look elsewhere. The sound quality is mediocre, there's no mic, and the durability issues are well documented. Foam tips breaking off in your ear is not a fun surprise. This is a purpose-built tool, not a general-purpose gadget. Buy it for the job site, the workshop, or the motorcycle. Leave it at home for everything else.
