Introduction
IEM Description
The SA6 EST is a hybrid IEM with six balanced armatures and two electret-style tweeters. It offers a bright, mid-forward tuning with a lean bass response and smooth but unspectacular treble.

Overall, a well-built set with niche appeal but limited versatility.

Silky highs and effortless detail. The ESt drivers really add air and sparkle without harshness really good for long sessions.
