The 64 Audio U4s Open Box has been tested and inspected by our team and is in like-new condition. 

64 Audio is entering the $1099 price bracket with a phenomenal offering in the 64 Audio U4s in-ear headphone, 64 Audio's most affordable universal IEM to date.

The 64 Audio U4s in-ear monitor (IEM) is a 4-driver, hybrid IEM with a powerful Dynamic low-frequency driver that results in powerful punch in the low-end. The U4s is the perfect IEM for anyone looking for a rich, enveloping listening experience. The U4s has bass and treble extension in spades. Notes have a generous sense of weight to their transients due to the strong bass boost and thicker midrange.

The U4s also comes with 4 different tuning modules so you can tune them to your liking. The 64 Audio U4s offer's 64 Audio's MX, the new M12 (no longer packaged with U4s), M15 and M20 modules that will all make varying differences in how you experience the bass and treble on the U4s with the MX being the least amount of bass to the M20 being the most. Flexibility at your fingertips!

The 64 Audio U4s is our pick for the top IEM at the $1099 price category. There really is no competition.

Joseph H. ★★★★★

I was a bit hesitant about open box, but the U4s arrived in pristine condition with all accessories. The clarity across the frequency range is exceptional, especially how the midrange handles complex tracks without any muddiness.

Edward ★★★★★

Was nervous buying open box but this thing arrived looking untouched, no scuffs on the shells at all. The bass hits deep without muddying the mids, and I've been wearing them for hours without any ear fatigue. For what I paid, this is easily the best value in my collection right now.

Richard ★★★★★

The open box unit I got honestly looked untouched, no scuffs on the shells at all. Bass hits clean without swallowing the mids, and the isolation is good enough that I forget I'm wearing them on the train. For this price it's a ridiculous value.
