ĐTN is an audio technology brand developed by Duc Tuan Nam Audio Research and Development Co., Ltd.
Our three co-founders come from different fields – business, electronics manufacturing and full-ribbon loudspeaker building – yet share one deep passion: music.
That love of music gave birth to ĐTN, with a clear mission: to faithfully turn the emotions of performers and composers into the emotions of the listener, through sound and music.
ĐTN brings together three brands: ĐTN Lab – full-ribbon loudspeakers, microphones and companion equipment; ĐTN Records – recording and music publishing; LENN Audio Design – music servers, DACs and the LENN Earth software. Our team gathers outstanding specialists in full-ribbon loudspeakers, electronics, software and recording, each with many years of experience.
At ĐTN, we know that fully turning the emotions of performers and composers into the emotions of the listener has never been simple. But with the strength of our team and the proprietary technologies we hold, we are fully confident in fulfilling that mission.
