Keep your ears healthy and have more fun
Some music is best when it’s heard live — but too much can affect your hearing.
Part of the pleasure of listening to music is the brilliance of the sound. Listen too long and too loud, though, and you can start to lose the ability to hear details. Concerts and festivals often expose fans to high volumes for long enough that it becomes a risk to their hearing.
Earplugs have always been a way to protect your hearing. But standard foam or rubber versions have a big disadvantage: they give you really awful sound. So we asked, why isn’t there a way to listen safely — and still give people the joy of brilliant live music?

Enjoy excellent sound anywhere
Don’t sacrifice good sound—or good looks—to protect your hearing.
Big, awkward-looking foam or rubber earplugs can draw attention. They also cut out much of the higher frequencies while letting lower frequencies pass through. The result? Muffled, bass-heavy sound. Not with SoundProtex. The patented technology in our elegant two-stage filters ensures brilliant, balanced sound.
To accomplish this, we used both a tuned membrane and a sound dampening mesh. When paired together, these components reduce high and low frequencies in equal measure. You get pure, balanced sound without losing any detail or clarity. Even better, these small, discreet earplugs are practically unnoticeable when you wear them.
Master of Sound
No matter where you are, discover a world of exceptional sound, with the highest quality audio sources
Experience music the way the artist intended, thanks to the outstanding fidelity of Sennheiser’s TrueResponse transducer system, which lets you hear every fine detail - and feel every emotion with up to 24bit/96kHz audio resolution. Best-in-class sound quality is ensured by support for lossless audio that brings flawless bit-for-bit transmission to wireless listening.
Balanced sound makes it easier to hear things around you
SoundProtex preserves the sonic details you need to be aware of your surroundings.
Although you need to protect your ears from excessive volumes, it’s still important to have an awareness of what’s happening around you. For instance, to understand what people are saying or hear an alarm. The balanced sound reduction from SoundProtex preserves the clarity of sounds and thus your awareness.
For instance, when we listen to people speaking, our ears rely on higher frequency details to make out the words. Standard earplugs can limit those higher frequencies too much. This can make understanding others difficult. Two-stage SoundProtex filters give you perfectly balanced sound that includes enough high-frequency details for easy conversations.
Freedom from noise and distractions
Enjoy the latest generation of adaptive ANC for superior noise attenuation
MOMENTUM True Wireless 4 automatically adjusts noise cancellation to your surroundings – so there’s nothing between you and your music. When you need to stay aware of your surroundings or hear others without removing your earbuds, the low-noise, natural-sounding Transparency Mode brings outside sounds back at a touch.
