Noise Isolation

While noise cancelling headphones often require heavy battery-powered technology to actively invert environmental sounds, noise isolating headphones physically impede exterior noise from reaching the ear canal; resulting in an extremely portable listening experience. For both in ear and over ear headphone designs, noise isolation works by combining the insulating properties of clever design and a comfortable fit to block disruptive ambient noise. For over-ear headphone designs, effective noise-isolation relies upon the angle and pressure with which the earcups sit on the ear. Earcups that sit too tight to the ear are uncomfortable and discourage longer listening sessions; earcups that sit too loose on the ear produce muddled sound and allow extensive sound leakage. The ErgoFit system developed for the RHA CA200 headphones relies on a sliding ball and socket mechanism to enable the soft ‘around ear’ pads to pivot on multiple axes, a structure that allows the earcups to move with the user and guarantee a good fit. Adjusting to the user’s movements and perfectly accommodating their profile means that nothing can interfere with a crystal clear listening experience. In-ear headphones generate noise isolation by the forming of a barrier within the ear canal to block ambient noise. RHA’s MA350 earphones offer small, medium and large sizes of ear-tip, while the MA450i features a choice of seven types of ear-tip, ensuring that every individual can find a comfortable fit and achieve excellent noise isolation. For the MA450i, RHA developed dual density ear-tips for optimum noise isolation; a soft silicone exterior provides a comfortable secure fit and keeps external noise out, while the firmer silicone interior produces a tight seal to the aluminium body of the earphone itself to prevent leakage as sound is channelled into the ear. When done well, noise isolation allows you to enjoy a secluded listening experience that delivers accurate sound representation across the full audio spectrum.
