Upon its release (Feb. 2024), IMMANIS quickly caught the attention of headphone aficionados everywhere. Superlatives began appearing as IMMANIS was making the rounds at the various audio shows. The praise and appreciation was further spread as bloggers began posting their impressions of this revolutionary development in headphone engineering.

It only takes a few minutes of listening to discover why this triple-ribbon design is so talked about. The soundstage is enormous.  It’s fast. It’s transparent. It’s lively and exciting.

Regardless of the size and calibre of your headphone collection, if it doesn’t include IMMANIS, you are missing a significant chapter in the book of TOTL headphones.  We encourage you to arrange for an audition of this rare creation.
