Hey bud, the KC06A are amazing. Don't lose heart. Play around with the tips. The stock filtered tips were no good for me. What actually worked for me was The stock, 'M size filtered tip, minus the filter' (i removed the filter from the tip). Sounded the best. The bass reaches super low and the mids are almost close to perfection to my liking.YMMV. Treble may get a little siblant at times but nothing in treble cannon category. Even today, they are one among the top few IEMS i reach out for.
