High Attenuation Hearing Protection for Petrol Equipment
The STIHL FUNCTION PLX earplugs are built for situations where noise levels are consistently high. With a strong SNR value of 38 dB, they provide serious attenuation across high, medium and low frequencies. That makes them well suited to chainsaws, brushcutters, hedge trimmers and blowers where prolonged exposure can quickly become uncomfortable without proper protection.
Compared with lighter-duty foam plugs, the FUNCTION PLX offers noticeably higher noise reduction. If you’ve previously used basic earplugs and still found machinery harsh on the ears, this is the step up within STIHL’s own range.
Comfort for Extended Wear
Made from soft, conically shaped PU foam, the plugs compress easily for insertion and expand to conform to the ear canal. The material is designed to provide a secure seal without feeling rigid or intrusive. For longer working sessions, that balance between seal and comfort matters.
The nominal diameter range of 7–12mm helps accommodate most adult ear sizes when correctly fitted. As with any foam earplug, proper insertion is key to achieving the full protection rating.
Compact, Practical Storage
Each set comes in a practical multi-box containing two pairs (four earplugs). The case protects them from dirt and damage during transport and features an integrated clip, allowing it to be attached to a belt, pocket or tool bag.
That small detail makes a difference on site. Hearing protection is far more likely to be used if it’s immediately accessible rather than buried at the bottom of a van or kit box.
When to Choose Earplugs Over Ear Defenders
- When you want lighter, less bulky hearing protection
- When wearing additional headgear or helmets
- During strimming or hedge cutting where head movement is constant
- As a compact backup set in your tool kit
For users who prefer minimal headwear but still require high attenuation, the FUNCTION PLX earplugs offer a straightforward solution. They’re not complex or over-engineered — just high-noise protection in a simple, reliable format.
