Here Comes Treble

Let’s face it, not every IEM pairs well with every song in your music library, especially when the drivers lean towards the low end. If you’re looking for something to nicely complement your favorite treble tweaked tunes, try on the Fidue A83 Hybrid IEM, the perfect portable solution for treble heads. For more information on the Fidue A83s, Head-Fi has a thread on them here.

Three’s Company

Featuring two balanced armature drivers for the highs and mids and a 10 mm dynamic driver dedicated to the bass, the A83 IEM offers a unique sound signature. With a bright and neutral treble that rarely results in sibilance, beautifully transparent mids that shine under the right settings, and a smooth, even bass that supports the whole sound rather than overpowering it, you get fully detailed and balanced sound every time.

Function Junction

As artistic as it is functional, the A83 sports red and blue full-bodied driver units designed by Benny Tan, a renowned headphone designer. With a gold plated MMXC connector stiffened to prevent unintended disconnections, a metal wedge that fits into the driver socket for a more stable fit, and a silver-plated OFC cable with a top end encased in heat shrink, you can count on the A83 for both flexibility and durability. The cable also has a custom 1/8” branded jack with metal tubing attached at the Y-split for stress relief. To top it all off, the Fidue A83 Hybrid IEM unique over-the-ear design fits nicely around your ear for comfortable listening. For an even more secure fit and ideal isolation, try some triple flange tips and maximize your musical pleasure.
