Custom Art was founded in 2012 in Poland by a fervent audiophile, Piotr Granicki. They specialize in making handcrafted iems, be it in universal or custom form. For custom iems, Custom Art is one of the few that offers the option of crafting them either in silicone or regular acrylic. They have a series of iems built with the FIBAE technology. FIBAE is also known as Flat Impedance Balanced Armature Earphone. I would like to Custom Art for the review unit of FIBAE 4. At the moment, you can purchase the FIBAE 4 from Custom Art.
- Driver Configuration: 4 Balanced Armature

Unboxing & Accessories
