Sennheiser SoundProtex Plus – Audiophile Adjustable Ear Plugs

Sennheiser SoundProtex Plus Earplugs

The SoundProtex Plus is a set of reusable hearing protection earplugs featuring patented two-stage acoustic filters that use a tuned membrane and sound dampening mesh to reduce high and low frequencies in equal measure, preserving balanced, high-fidelity sound at a safer volume level. Three interchangeable acoustic filter strengths (Low, Mid, High) and an additional full block filter provide the right level of protection for any situation. Medical-grade TPE ear tips are available in three sizes (S, M, L) and are free of plasticizers and other irritants.

• Reduce decibel intake while preserving speech clarity and sonic detail via 2 stage acoustic filter
• Four filter strengths: Low, Mid, High, Full for maximum isolation
• Medical-grade TPE ear tips in three sizes (S, M, L)
• Reusable — rinse under water or wipe clean

Highlights & Key Features

Two-Stage Acoustic Filters
Standard foam or rubber earplugs cut out higher frequencies while letting bass pass through, resulting in muffled, muddy sound. SoundProtex Plus two-stage acoustic filters each use a tuned membrane and a sound dampening mesh to reduce high and low frequencies in equal measure. This patented technology ensures crisp, balanced sound at a safer level. Everything you hear remains brilliant and clear, and speech is easy to understand because enough higher frequencies are passed through.

Three Filter Strengths & Full Block
The SoundProtex Plus includes three interchangeable acoustic filter strengths — Low, Mid, and High — allowing you to choose the level of volume reduction best suited to the environment. The Mid filter is suited for traveling, festivals, concerts, and other events. For situations where maximum sound isolation is desired, the included full block filters eliminate as much sound as possible and can also protect ears from water.

Comfort & Materials
The ear tips are made of soft, flexible, medical-grade TPE material that is free of plasticizers and other substances that could irritate the sensitive skin in the ear canal. Three ear tip sizes are included — Small (5–10 mm), Medium (6–11 mm), and Large (7–12 mm) — to ensure a comfortable, secure fit. The earplugs are small and discreet, barely noticeable when worn.

Reusable & Easy to Clean
SoundProtex Plus earplugs are reusable. After use, rinse under running water or wipe clean with a cloth. Alcohol cleaning is also safe. Store in the included storage pouch.
