FiiO FA9 Knowles 6 Balanced Armature Driver HiFi Earphone with Detachable MMCX Cable DLP 3D Priting

6 Knowles BA drivers with the carefully designed 4-way crossover & low-frequency ultra-long sound tube completely covers the entire audible frequency range with a sound that will take your breath away
The FA9 marks the first time FiiO has employed Knowles EJ balanced armature drivers, commonly used among high-end IEMs.
FA9 employs a specially-designed ultra-long sound tube 80.6mm in length which acts as a low-pass filter that filters out unneeded extra mids & highs to ensure a seamless frequency response.
The FA9’s use of electronic crossover technology allows you to tune the sound to exactly the way you want with 3 sound adjustment switches.
Detachable MMCX design including a 3.5mm-terminated cable made of 8-strand monocrystalline silver-plated copper gives better audio performance under the naturally-occurring yet adverse skin effect.
