Product information "Audeze LCD-S20"
The new closed-back LCD-S20 headphones are Audeze 's first planar magnetic headphones to feature patent-pending SLAM technology for powerful bass reproduction and improved spatial imaging , as well as a new magnetic earpad attachment system .
SLAM , short for "Symmetric Linear Acoustic Modulator ," is a new patent-pending technology introduced in the flagship CRBN2
headphones in late 2024. The LCD-S20 is the most affordable model in the LCD series , opening up new possibilities for aspiring producers, musicians, and audiophiles who need acoustic isolation to access studio-quality sound.
Because they are closed-back headphones , they are ideal for recording in the recording studio. The superior impulse response of the planar magnetic drivers means you can clearly hear the timing of the click track or snare drum to keep in time. Excellent passive noise cancellation prevents microphone transfer and protects your hearing.
