Ferrum maintains a consistent design across its product line, and the WANDLA HP is no exception. This sleek, rectangular unit features a signature brown accent panel with a glowing Ferrum logo, adding a touch of elegance. The build is light yet sturdy, housing advanced technology without excessive weight.

During testing, I paired the WANDLA HP with various high-impedance headphones, including the Dan Clark E3, Sennheiser HD 650, Final Audio D8000 DC Pro, and Abyss JOAL. Initially, the volume required a high setting, but after adjusting the gain settings, I achieved optimal headroom and driving power, allowing each headphone to reach its full sonic potential.
