Sony announced the IER-M500 in-ear monitors on July 8, 2026, marking a move by its pro-audio division into the IEM category for live sound. The company’s existing professional audio presence has centered on studio-oriented tools including the 360VME Virtual Mixing Environment, MDR-MV1 mixing headphones and C-800G studio tube condenser microphone.

The IER-M500 was developed with monitoring engineers and is intended to provide a secure, stable fit for stage use. Sony adds a thin polyurethane wall inside the earpiece to increase onstage isolation, while a dynamic driver and large acoustic chamber are shaped for deep, controlled bass. The internal structure is also described as optimized for high-frequency reproduction. The model is offered in red and blue, black, and clear versions, with four eartip options, flexible ear supporters for added stability when needed, and a 1.6 m detachable cable for connection to an RF pack.

Pre-sale pricing is $119.99, with deliveries expected in late August 2026. For live workflows, the source-supported value is practical rather than decorative: the IER-M500 combines stage-focused fit, added isolation and RF-pack connectivity in an entry-level product that Sony explicitly frames as a professional monitoring tool.
