CT-400 Pro's Sound Design

The CT-400 was developed practically to fulfill the demand from professional touring bands (friends of CTM) who urged for an IEM that would finally deliver an advanced level of frequency separation along with a pristine quality of sound.
CT-400 Pro’s unique sound signature quickly became the number one preferred IEM. An updated 3-way crossover improved the frequency ranges optimization to deliver cleaner signals to the 4 balanced armature drivers, allowing you to create an unbelievable In-Ear Monitor mix.
Once panning is thrown into the equation, you can close your eyes and see the music coming from every direction.
