Summary: I was overall unimpressed with the Focal Spirit One cans. I'm hardly a connoisseur of headphones, but I was let down a bit by the sound and the manufacturer's advertising.
I compared these to my reference headphones, which are at the moment a pair of Sony MDR-V6.
Pros: Warm, good bass, feel sturdy, good aesthetics, detachable cable, nice included accessories and case
Cons: Not actually circumaural, cheap cables, overbearing clamping force, highs can be shrill
Summary: Very good headphones if you want something fun, lively and bassy. I was really impressed at first but with time I started to notice the short comings. Although relatively open sounding the sound is quite synthetic, almost forced.
Summary: The Focal Spirit One really took me by surprise.
A friend of mine praised them a lot so I asked him to lend them to me for a little test.
When I opened Focal Spirit Ones’ case, I found 2 detachable cables, one for smartphones with volume control, and one for normal usage, a 3.5 to 6.3 jack...
Pros: excellent, fast, punchy and well extended bass; lush and present mid-range ; meaty and natural sound ; good treble with no harshness or sibilance ; very fast and energetic sound (excellent PRAT); very good isolation; good overall build quality; excellent for portable use; detachable cables
Cons: the sound is a a little congested; voices could use more texture ; could be uncomfortable for many
Excerpt: I do not know if the Focal is a good choice, if only for the lack of comfort. Moreover, these headphones are suitable for a certain type of music in my opinion. A little pricey for what it is.
Summary: These are beautiful looking headphones in my humble opinion. I felt a little self conscious when I first wore them on the commute to work, but have had several comments of admiration from other regular commuters. They are a little on the big size, but no bigger than a lot of other brands out there.
Excerpt: Over 1 year now AKG / Sony / Sennheiser / Beyerdynamic What I love the most .... er .... perhaps we did change 3 times and it deserves to be still .... Oh yes, I also love myself realized that
Summary: Just got these headphones for my birthday and they are just fantastic. They may not be as good as the AKG's that are a similar price but those things are huge and completely impractical because of their size and also lack a mic for mobile phone use.
