64 Audio’s Aspire 4 is Out Now!

64 Audio has just released its all new “Aspire 4”, their latest next-generation universal IEM tailored for musicians and live music professionals. With a MSRP of £899.00, it is 64 Audio’s most affordable UIEM on the market.

64 Audio Aspire 4 – World Class Sound & A New Direction

At first glance the most obvious difference of the Aspire 4 to the rest of 64 Audios UIEM line up is its shape and overall look. Whether you’re just getting into monitoring with in-ears, not ready for customs, need a backup set, or simply prefer generic fitting products. 64 Audio guarantees the Aspire 4 offers best-in-class sound and ergonomic fit. In addition to this, unlike their other UIEMs (U4s, U12t, Fourté, etc) the Aspire 4 is built with an ABS molded shell and a stainless steel tip. Finally it’s also built with an IPX (or T2) socket as opposed to a 2-pin socket that is feautred with all their other UIEM’s.

How does it differ from other Four-Driver models like the U4s and Fourté?

Along with the redesigned form factor and shell materials, the Aspire 4 is 64 Audio’s only four-driver model that is crossed over 3-ways (lows, mids, highs). As opposed to the other models that are 4-way crossovers. While Aspire 4 doesn’t use 64 Audios tia™ driver for the highs, they have developed a revolutionary waveguide to bring its highs to their incredibly high standards. Furthermore, it is also the only UIEM specifically designed and tuned for musicians and live-audio professionals as opposed to audiophiles and high-end audio enthusiasts.

Aspire 4

“With live music at the forefront of our tuning criteria do we make a highly accurate unforgiving studio monitor or a contoured device that helps musicians hear themselves more effectively? As with many of our monitoring tools the answer is somewhere in the middle. Huge bass that can reproduce some of the toughest frequencies in the audible spectrum with quick ease. Forward mids that are precisely elevated for articulation in the most vital region of instruments and voices. Plenty of top end sparkle really separates Aspire 4 from any other UIEM in its class, making this powerful sound signature a perfect blend of accuracy and musicality.”
