FiiO FA9 Headphone Earphone Wired in-Ear High Resolution 6BA MMCX for Smartphones/PC/Laptop/Tablet (Black)

Users say:
The FiiO FA9's are a great choice for those looking for a high-end IEM with a variety of technologies found in multi-thousand dollar IEM's. They are solidly constructed and come with a nice cable that is comfortable around the ear. The IEMs of other brands are not as good, but the FA9's offer more clarity, detail, soundstage, and richness than all other IEMs. They are also a great value for the price, but the product that is delivered ought to be priced much higher given the sheer quality.

HIGH PERFORMANCE The 6 Knowles BA drivers per ear, together with the carefully-designed 4-way crossover and low-frequency ultra-long sound tube, completely covers the entire audible frequency range with a sound that will take your breath away. More lifelike sound The FA9 wired headphones marks the first time FiiO has employed Knowles EJ balanced armature drivers, commonly used among high-end IEMs. FiiO and Knowles collaborated to come up with the custom EJ-33877 driver for use in the FA9 for excellent mid-frequency performance with hauntingly realistic vocals. 80.6mm ultra-long sound tube The FA9 earphones employs a specially-designed, ultra-long sound tube 80.6mm in length. The sound tube acts as a low-pass filter that effectively filters out unneeded extra mids and highs from the drivers to ensure a seamless frequency response. The sound tube also ensures the mid-bass is smooth and clean while enhances bass texture in general. 3 sound adjustment switches, 8 possible sounds The earbuds FA9s use of electronic crossover technology allows you to tune the sound to exactly the way you want with 3 sound adjustment switches. The impedance, bass, mids and treble adjustment depends on what music you are listening or what your preferences are! REMOVABLE CABLE Detachable MMCX design including a 3.5mm-terminated cable made of 8-strand monocrystalline silver-plated copper cable gives better audio transmission performance under the naturally-occurring yet adverse skin effect. What this means for actual listening are improved bass and mids, as well as more coherency between all audio frequencies. Black
