hey all care OS reviews so recently we just did a review on the kz zsn in-ear monitors which for 20 bucks are definitely a steal but we're actually a little bit late to the party in fact kc have actually come out with the zsn pro already so the pro you may think of as a slight upgrade to the original zsn but it also sells for about five dollars more so these go for 25 bucks compared to twenty dollars now the difference really is just in the driver technology it's so a dual driver setup you have one balanced armature but instead of using the hybrid dynamic it's been replaced by a magnetic dynamic driver which claims to offer a wider frequency range so now this can reproduce sounds from seven all the way up to 40,000 Hertz which is extremely wide compared to the zsn which had a frequency range of twenty to forty thousand hertz for the price these are definitely still very much affordable
