Understanding the Sound
The KTXPro1 headphones utilize 60 Ohm Titanium Coated drivers, delivering a wide frequency range from 15-25,000Hz for clear and deep audio. They are designed with an "open, hear-through sound" which means they allow some ambient sound to pass through, providing a more natural listening experience and maintaining awareness of your surroundings.
