The "se" "STEALTH" version takes the previously known planar magnetic HE1000SE sound to a new level. Extremely sophisticated high, natural mid and firmly precise bass can be expected. The 1-nanometer-thick membrane is capable of extremely fast and precise sound reproduction between 8Hz and 65000Hz. The interchangeable cabled, high-quality, yet physically flat headphones have an asymmetrical, ear-shaped design that guarantees comfort while offering a secure wear. The HE1000se is an audiophile headphone with a detailed sound that won't disappoint.
