Digital Earplugs MM4000
The 'sound' can be heard, but only the 'noise' is cut out.
Even in noise-canceling mode, you can still hear necessary sounds, so you can feel at ease! You can also listen to surrounding sounds while wearing earplugs in ambient sound mode. This is useful in work environments where noise is constantly present and conversations with nearby employees are necessary!
