You’ve captured the essence of Trifecta beautifully in your review. Floating in a sphere of sound is exactly how I would describe it.

Letshuoer DZ4: The poor mans Trifectra. (3) 6mm titanium diaphragms and (1) 6mm R-Sonic passive filtering module. Has the unified sound of a single driver iem but more powerful and detailed. Excellent tight bass response and more extended highs than a lot of larger diaphragm drivers. Nice cable also. Very impressive sound for $89.

I read your review of the xenon 6 the other day. And if I read this one, I hope you can give us a comparison?
