History
The evolution of ETA Audio, year by year. Each photo links to its product page.
A year of collaborations.
The Bravo 6V6 tube amp (hand-wired by Straitwire), the Associate DIY amplifier PCB, and the APOS × ETA open-back (in development).
ULI — the only AlNiCo headphone in production.
Silver alloy voice coil, biocellulose diaphragm, and ultra-low impedance design — the result of years of driver experimentation, handcrafted in small batches.
Ada arrives — a 40mm biocellulose driver tuned for midrange sweetness and articulate treble.
The Ada — our open-back. 40mm biocellulose driver, N52 magnets, non-magnetic grill. Tuned for midrange sweetness and articulate treble.
O² launches — the on-ear graphene composite driver, refined bass on-ear headphones.
The O² — our on-ear evolving a cult-classic graphene driver. 50mm graphene composite, N52 magnets, vibration-dampening kinetic coupler.
The Mini line expands — Closed for isolation, Semi-Closed for hybrid acoustics.
The Mini series: Mini Closed for full front-seal isolation, Mini Semi-Closed for hybrid open clarity with closed impact.
Mini Open — the first folding, supra-aural ETA. Compact, vented, and minimalist.
The Mini Open — our supra-aural open-back. Graphene composite driver, flexing surrounds, N52 magnets. Folds for travel.
Genesis. The first ETA — a graphene-diaphragm, 3D-printed open-back headphone that defined what was possible at a boutique.
The Genesis OG — our open-back flagship. Graphene diaphragms, flexing surrounds, N52 magnets, 300-ohm voice coils.
