Clarity Aloft designed its Slim Replacement Foam Tips specifically for its headset users with smaller ear canals. These streamlined Comply Canal Tips deliver the same impressive Noise Reduction Rating (NRR) of 29.5 dB provided by the larger, standard earpieces. They've been specifically designed to slowly expand following placement in the outer ear canal, resulting in a snug, ultra-comfortable fit. In addition to blocking out harmful cockpit noise, they've also been optimized to deliver crystal clear communications from the headset's integral speakers to the user's ears. Each earpiece is good for 5 to 7 flights and can be machined washed in a shirt pocket to extend their lifespan. A low-cost, high-value component of Clarity Aloft's revolutionary aviation headset.
