In our review of the JadeAudio JT9, we’ll see if a smartphone can drive them without a dedicated amplifier. FiiO claims a sensitivity of 95 dB/mW and says they’re easy to drive. We’ll also investigate if the sapphire-aluminum diaphragm coating and 28-nm process technology, which FiiO says improve detail retrieval and voice coil durability, make a noticeable difference. Finally, we’ll assess the comfort of these 365-gram open-back headphones, as FiiO claims they don’t exert the typical pressure on your head associated with this style.
