All of our amplifiers shipped from March onwards will have the external noise reduction function ‘NR’ (an abbreviation for Noise Reduction) added. NR is a function that greatly reduces the contamination of radiation noise emitted from smartphones, as well as communication equipment in stations and on the street. This will make the listening environment more comfortable for users. Please note that the NR addition service for products that have already been sold is only available in Japan.
