There is a noticeable difference between my phone's mic and this lapel mic. It's play-back sounds are clarity,crisper,and live.
This was tested on my iphone 5S because apparently apple forgot to packed the charger cable adapter with my iphone 7...lol!
Also been used with my desktop and laptop for video calling. Works excellent!
It's nice that it came with a pouch and extra wind muffs.
