Frequently Asked Questions
The soundstage is defined and intimate, not as expansive as some open-back designs, but provides excellent localization for stage use.
The foam tips provide better isolation and a slightly warmer sound, but the silicone tips are perfectly acceptable for many users, especially in less noisy environments.
While usable with most devices, a dedicated headphone amp with sufficient power will truly unlock the FA 666 XB's potential, especially in live sound situations.
