Overwhelming Bass with Smooth & Detailed Vocals
The 10mm biocellulose dynamic driver provides deep sub-bass response, while the 8mm LCP dynamic driver enhances mid-bass punch and vocal richness. Precision-tuned balanced armatures ensure highlighted yet sibilant-free vocals with excellent extension, suitable for various music genres.
