Audio-Technica Japan is a well-known company in the world of headphones and earphones. They have a wide range of headphones and earphones and they have recently launched a new Sports series. In this review, I am talking about the Audio-Technica ATH-SPORT3. The Audio-Technica ATH-SPORT3 has a new IPX5-certified protection against water and sweat which is rather unique in the market. So as such the Audio Technica ATH-SPORT3 is designed primarily for those who workout. That said they can be used by anyone with a less sedentary lifestyle as well!
