KC Chief

After hearing the original Ostry KC06 Earphones, we figured that the ideal balance between portability and performance had finally been reached, but fortunately, we were mistaken. An improved edition of the KC06 that includes a warmer sound signature, a more musical presentation, and some slick red accents, the Ostry KC06A Inner-Ear Earphones will become your new go-to travel buddies.

Grade A Sound

Thanks to the 10 mm CCAW double cavity drivers and the EBT diaphragm, the KC06A puts out some serious power. Delivering an overall warmer and richer sound than its forebear, the bass has more weight and control, the mids stay shining while gaining a bit more balance, and the treble has been smoothed out to avoid any sibilant splashes. To complete the aural picture, the instrument separation brings new sections to life and the soundstage is wider than almost any inner earphone we’ve tried.

KC and the Sunshine Band

While these earphones will improve when plugged into a headphone amplifier, their low impedance and high sound quality make them easily operable out of your smart phone. To finish out the package, the drivers are surrounded by titanium housing and the attached cable is made of environmentally friendly and anti-bacterial TPU cable, making for a distinctly metallic overall structure. Unique earphones boasting unbelievable sound, the Ostry KC06A Inner-Ear Earphones are the buds you’ve been dreaming of since your first MP3 player.
