The FIBAE 5 is a reference-oriented in-ear monitor designed to deliver tonal accuracy, coherence, and reliable performance across all audio sources. Developed by Custom Art, it applies their Flat Impedance Balanced Armature Engineering (FIBAE) technology in a refined five-driver configuration—balancing precision with musical engagement.
Featuring five balanced armature drivers, the FIBAE 5 is tuned for a neutral yet slightly expressive presentation. Bass is tight and controlled with natural body, mids are clear and articulate with accurate timbre, and treble is smooth and well-extended without excessive brightness. This makes it suitable for both professional monitoring and long, fatigue-free listening sessions.
Like all FIBAE designs, the FIBAE 5 maintains a flat impedance curve, ensuring consistent sound regardless of output impedance. Whether used with wireless stage systems, audio interfaces, or portable players, the intended tuning remains intact—allowing users to rely on a predictable reference sound at all times.
The FIBAE 5 emphasizes coherence and balance over sheer emphasis, offering a well-integrated soundstage and natural dynamics. It is an ideal choice for musicians, engineers, and audiophiles seeking a dependable reference monitor with a touch of musical warmth, without sacrificing accuracy.
