What Makes It Special

  • A classic IEM that delivers neutral sound and is one of the original "great value" IEMs

Our Thoughts

When the Ostry KC06A first came out, it quickly received high praise for being an exceptional IEM for its cost. Overtime, more products have come to the market and the KC06A has been somewhat overshadowed by new entrants. That said, it still has a loyal following and continues to be a well made IEM.

While the team here may gravitate to a few other IEMs at this pricepoint, the Ostry KC06A is by no means a bad choice.
