Sony is officially back in the professional in-ear monitor (IEM) space. The company has announced the IER-M500, a new pair of stage-focused earphones designed for everyone from aspiring musicians to seasoned performers. Rather than chasing features like active noise cancellation or spatial audio for casual listening, the IER-M500 is built with one goal in mind: helping artists hear themselves clearly during live performances.
Built for the stage, not the daily commute
At the heart of the IER-M500 is a newly developed dynamic driver paired with a large acoustic chamber and an optimized internal acoustic structure. Sony says this combination delivers deep, controlled bass alongside crisp high-frequency detail, helping performers accurately monitor vocals and instruments even in loud environments. The earphones are also Hi-Res Audio compatible, covering a wide frequency range for more detailed sound reproduction.
Rather than relying on active noise cancellation, Sony has focused on high passive noise isolation. A fully sealed design, thin polyurethane noise-isolating eartips, and the large acoustic chamber work together to block external stage noise, allowing musicians to hear more clearly without increasing monitoring volume.
Comfort has also been a key priority. Developed in collaboration with monitoring engineers, the IER-M500 features Sony’s proprietary ear-fitting supporters, flexible ear hooks, four sizes of eartips, and a 1.6-meter detachable cable built for repeated stage use. The moisture-resistant earphones will be available in Clear, Black, and Red & Blue transparent finishes, with clearly marked left and right earpieces for quicker setup before performances.
Expanding Sony’s professional audio lineup
With the IER-M500, Sony is filling a gap in its professional audio portfolio. The company says the new IEMs complement products like its MDR-M1 studio headphones, microphones, and 360 Reality Audio ecosystem, extending its creator-focused lineup from recording and mixing into live stage monitoring.
The Sony IER-M500 is available for pre-order now in the U.S. for $119.99, making it one of the more affordable professional in-ear monitors in Sony’s lineup. While they aren’t aimed at everyday listeners, musicians and performers looking for dependable, stage-ready monitoring now have another option from a brand that’s returning to a category it helped shape.
