Spirit One is Focal’s first venture into the mobile headphones market, and it is a headset that comes in a luxurious package and includes a beautiful zip-up pouch for storing and protecting the product. These are closed-back type headphones with an in-line remote controller and microphone that’s compatible with music and telephone services on iOS devices and smartphones. The anti-winding cable is completely detachable. Focal has used very high quality materials in the construction of these Spirit One headphones, and they are lightweight and comfortable to wear. The pads are very soft, and do a good job of insulating against external environmental noise. Sound quality is excellent, with a great emphasis on high frequencies but with plenty of bass when your music demands it.
