Normally the sound pressure difference between the left and right channel is allow 3 DB, most HiFi brand require the difference as 0.3-0.6DB, While , the PAA-1 carries on the serious standard of 0.2 DB difference ( tested before assembled, there are some difference of the finished products) . It is the most serious standard with the low price earphones. This also firmly ensures the PAA-1 can be definitely the best earphones below USD 100.
