Sonic Signature & Pairing
NX8’s tribrid driver stack is built to cover the full spectrum: a dynamic driver for low-end foundation, balanced armatures for fast mid/treble articulation, and a piezoelectric element for top-end extension. For the best imaging and control, pair it with a clean, stable DAP and experiment with tips to dial in seal and tonal balance.
To unleash the full potential of this device, we recommend pairing it with gear from our Digital Audio Players Collection.
