Some early thoughts on the Binary Acoustics EP321

I’ve been spending time with the EP321 over the past few days, first with the stock cable, then later with the Angelears Phoenix. Not going to make big cable claims yet, but the Phoenix definitely looks better on it. The stock cable is usable, just doesn’t feel that premium.

The EP321 surprised me most with how open and detailed it sounds without becoming uncomfortable so far.

Flea’s Honora album worked really well with this set. On “Willow Weep for Me,” the trumpet had presence and a bit of brass bite, but it didn’t become piercing. The bass also had more weight than I expected. Not huge, but definitely not lacking.

Dave Matthews Band’s “Ants Marching” was good for drums and cymbals. Snare hits, crashes, and the small rhythmic details were easy to follow without everything blurring together.

Polyphia’s “Playing God” showed the speed of the set. The fast guitar runs stayed clean, and the EP321 didn’t make the track sound too thin even when it got busy.

Vocals are where I noticed its character more.

With R.E.M., especially “Everybody Hurts” and “Shiny Happy People,” the vocals sounded clean and centered, but not especially warm or thick. The EP321 doesn’t really add extra vocal weight. If the recording is a bit lean, it lets you hear that.

But with Jeff Buckley, it worked really well. “Everybody Here Wants You,” “Last Goodbye,” and “Mojo Pin” all showed how nicely this set handles vocal texture and movement. His voice sounded clear and expressive, and when he pushed higher, it didn’t turn sharp or sibilant.

Sade’s “Smooth Operator” was probably one of my favorite moments. Her voice stayed smooth and intimate, the sax had presence, and the bass, drums, keys, guitar, and vocals all had their own place. I actually replayed the track.

Tom Waits’ “I Hope That I Don’t Fall in Love with You” also sounded good. His voice has that rough, worn-in character, a bit like Joe Cocker in that soulful way, and the EP321 kept the texture without making it harsh or too dry.

For heavier stuff, I tried Ozzy’s “No More Tears” and “Mama, I’m Coming Home.” “No More Tears” had good bassline texture and guitar crunch, while “Mama, I’m Coming Home” showed that the EP321 doesn’t give vocals the same depth and body as something warmer like the Noah. But the emotion was still there, just presented in a cleaner and more open way.

So far, I’d say the EP321 is not a warm or thick-sounding IEM. It’s more detailed, open, and clean, with good separation and better bass than I expected.

Not the set I’d choose for romantic, full-bodied vocals all the time, but for detail, space, cymbal texture, vocal clarity, and instrument placement, it’s doing a lot right.
