The Ti IEM utilizes pure titanium foil for the diaphragm material. All components inside our IEMs were 100% designed and tooled in-house, resulting in a totally unique product. The sonic signature of the Ti IEM is very aggressive, with enhanced bass and treble response. It tends to be preferred by those who listen to electronica, dance, and bass-heavy music. Not our most objectively accurate IEM, it is a lot of fun to listen to. All our IEMs feature polycarbonate bodies for high strength and zero resonance, custom front-and-rear tuned volumes, MIM logo caps, butyl rubber strain reliefs, and N48H grade magnets.
