The Sennheiser IE 400 PRO dynamic, in-ear headphones for wireless monitoring systems offer musicians, DJs, and sound engineers a rich listening experience with clear, studio-like accuracy, when performing in quiet to moderately loud stage environments. With a secure, comfortable fit rivaling custom-molded models for isolation, the IE 400 PRO shields the user from excessive stage volumes and poor room acoustics to deliver punchy sound with transparent midrange.

Made to exacting specifications at Sennheiser's German factory, the smoky black IE 400 PRO features elegant, low-profile housings that are built to survive the rigors of live gigging, while providing a secure, comfortable fit so you can wear them for hours without fatigue. With the IE 400 PRO monitors, you can forget you're even wearing in-ears and feel more connected with your music and the audience, allowing you to perform at your best.
