The Minuendo Lossless Adjustable Earplugs protect your ears in loud environments, whilst still providing a natural frequency response. Whereas conventional earplugs can dull the sound when in use, the Minuendo Lossless Earplugs deliver high-end clarity - perfect for musicians, bar staff, audio engineers and anyone who works in high-volume spaces. The 'lossless' design refers to the fact that it delivers a flat response, normally reserved for high-end custom and moulded earplugs. Cutting-edge membrane technology eliminates frequency degradation, for the best possible listening experience. In comparison to foam earplugs, the Minuendo earplugs provide rich, full-bodied sound whilst still protecting your hearing and reducing overall volume. One of the most unique features of the earplugs is the stepless adjustments. The built-in lever located on top of the earplugs allows you to manually control the attenuation, so you can find the perfect sound for you. Not only do they sound great, they feel great too. Complete with the earplugs are eleven sets of eartips including foam, silicone and flange tips for the perfect fit. The snugly fitting eartips will not be dislodged when you sing or move your jaw, ensuring maximum comfort and fidelity on stage or at work.
