FiiO JT9 Open Back Planar Headphones
Now In (09.10.26)
Overview:
Next-generation proprietary planar driver:95×86mm large driver + sapphire coating, delivering deep bass extension and a natural and expansive soundstage.
1μm ultra-thin diaphragm:Lightweight design with lightning-fast transient response, precisely capturing the finest treble detail.
Dual-coating technology: Sapphire + aluminum dual coating balances excellent conductivity with high rigidity for finer resolution.
