Stellia is one of the best closed headphones period. It will hug your head and entice you with an engaging, punchy sound that doesn't let you go.
Stellia is a very nice package, in every sense. It comes in a luxurious box, inside of which is a premium case that protects the Stellia and a cable of your choice. When you put it on your head, the soft leather immediately seals you off of the outside world, so you can start listening uninterrupted.
It strikes a perfect balance of fun, punchiness and detail without being harsh or muddy and is very easy to drive. Reviewers agree:
Could I be happy with only one pair of headphones? It seems that I could.
If all closed-back headphones could sound near as good as the Stellia, I’d give up on my perhaps antiquated belief that I prefer the sound of open-backed headphones. Yes, to us mere mortals, the Stellia are near absurdly expensive for a pair of headphones. However, they deliver the goods. To be considered the very best, you can justify the price tag.
The Stellia can.
What we have here is probably the best or one of the best closed-back headphones money could buy. There are perhaps one or two that could perhaps compete with the Focal Stellia but be ready to dig even deeper into your bank account. The Focal Stellia has a stellar look and does so many things audibly well with such good sound quality that it is gonna be hard to beat them.
The Focal Stellia is in one word stellar. A closed back that does so many things right is hard to come by and I would say almost impossible but Focal pulled it off. For my last few words in this review, I would like to say and direct the words to the entire Focal staff, ‘félicitations pour la fabrication d’un super casque’. Well done.
Ask me for the best price!
Technical Specifications

The black line is something that could be called the „ideal“ curve of what a headphone should sound like. The Harman Research Group has a range of scientific studies around audio and the human perception of it - one of which was, how should a headphone sound like to be favored by a majority of people, no matter the age or other demographic variables? This result is called the Harman target.
From left to right we have the sub bass, bass, mids and then the curve finally tilts upward where the treble begins - this part of the frequency spectrum gets amplified naturally by the shape of the human ear.
This headphone gives you a little bit of bass for fun - but dips down at 150-200Hz, early enough to just sound punchy, not bloated. It comes back up and stays slightly under the Harman curve in the treble region, to give you just enough detail to hear everything, but not be fatiguing in long listening sessions. Very well done.
