Super Fidelity Monitoring Earphones
One single full range driver is as a dream come true for all audio professionals and audiophiles!
SF driver is game changer for in-ear monitoring
Development of unique target frequencies for professional musicians
direm PRO is a reference earphone for professional musicians and audiophiles.
• Improved low-frequency dynamic response
• Able to reproduce dynamic and dense bass frequency (20-100Hz)
• Making the vocal image harder and clearer (1,000-3,000Hz)
• High-frequency characteristics are flattened as much as possible to improve the three-dimensional effect and sense of space (5,000-10,000Hz)
• Reproduction of ultra-high frequencies without distortion enables delicate expression of musical instruments (10,000-16,000Hz)
Provide measurement data for each unit on the production line.
We provide left-right frequency and distortion characteristic measurement data in the audible frequency band by using German Klippel equipment, the world’s best acoustic measurement equipment.
