MajorHiFi: highlighted the JT7’s foldable design, lightweight build and plush ear pads, calling it comfortable for long listening sessions. Mobile Audiophile: praised its open, airy and spacious technical presentation, with accurate imaging and strong layering for the price. ⚠️ Warning ⚠️ Warning: The FiiO JT7 may cause sudden disbelief that planar headphones can be this light, this foldable and this affordable — followed by an urgent need to test every DAC/AMP in the house “just to be sure.”
