64 Audio U4s (Four Driver, Hybrid IEM)

This is the place to discuss all things about the 64 Audio U4s.

The U4s is 64 Audio’s latest universal IEM that meshes a single-DD, 2BAs, and a single tia driver. At a price point of $1099 USD, it is the most accessible IEM in the brand’s exclusive lineup.

I’ve been evaluating it for the last couple months, and I have a lot of good things to say about it. You can read my review here for the full rundown: 64 Audio U4s Review - Carving Out a New Sweet Spot – Headphones.com
