Focal has stated that this headphone was aimed at a more general consumer audience, and that they will building more upscale models.
Here's the quote posted in a review on 6moons:
Focal's Pierre Maillard: "We are launching our first headphone set. It is a consumer-oriented model. It includes a remote for the iPhone. The retail will be €199. All of the design and tuning work took place at Saint-Etienne in France like all Focal speakers. The product itself is being manufactured in China. The Spirit One is the first of a whole new line of headphones. It's notjust another one-shot deal because all manufacturers do that now. Neither is it an off-the-shelf Chinese headphone with a Focal logo stuck on. We kick off our new line with the most affordable consumer model which will also be available in white. After that we will add audiophile and pro-audio models and move upmarket step by step (perhaps all the way to Utopia level - who knows?)."
I doubt that a manufacturer like Focal would put out a bad headphone. Maybe the Spirit One is actually "correct" and the others are "wrong"? Nobody ever mentions tonality or musicality, it's always bass and treble. Does it feel like music or just a bass/treble/midrange delivery system?
Myself, I've always found that headphones that sounded great right away usually were bad in the long run, and ones that sounded "odd" initially turned out to be wonderful.
