Sonorous III by Final Audio


I had the opportunity to listen to the Sonorous III by Final Audio, a Japanese audio electronics brand that very few people are familiar with stateside.

A little on the brand itself, Final Audio was established in 1974 and primarily sold cartridges for vinyl record players before expanding into amplifiers and speakers. If you’re wondering why you haven’t heard of Final Audio before, it’s because the name wasn’t adopted until 2009 when they began selling their own earphones and headphones.

The Sonorous III is one step up from Final Audio’s entry level Sonorous II (go figure), and is boasted to employ the same driver technology as their flagship Sonorous X.


The build of the Sonorous III is very sturdy, and their over the ear design is comfortable yet large on my head. The housing is made of hardened ABS plastic, with a titanium diaphragm driver unit integrated into the front plate for suppressed resonance.

How do they sound? My first impression of the Sonorous III was that they have forward mids, and are very analytical. Extended listening with a wide variety of genres and artists revealed that they are exceptional for vocals, and shine in the high mid-range. The lower frequencies were punchy and accurate, yet very subdued below 125Hz.

I would recommend the Sonorous III to intermediate audiophiles listening to dynamic tracks that benefit from their wide sound stage. Classical, Jazz, Classic Rock, and Heavy Metal all sound excellent through these cans. The pair I listened to were fresh, and I’m excited to give them another try once they’ve been burned in.
