Sony has introduced the IER-M500, a new professional in-ear monitor (IEM) aimed at performers and monitoring use. Multiple outlets describe the product as stage-focused, targeting musicians, vocalists, monitor engineers, and creators who need reliable in-ear monitoring during live performance. The IER-M500 uses a 5mm dynamic driver and is built around a sealed acoustic structure designed to deliver high passive noise isolation. Sony also includes a detachable cable, along with accessories intended to improve fit and comfort, including flexible ear hangers and multiple ear tips and fitting supports, plus a cable clip to help secure the cable during use.

Several sources emphasize that the IER-M500 is intended to take pro-audio features to a wider audience. One outlet notes support for High Resolution Audio. Pricing is reported as $119.99 in the US, and the IER-M500 is offered in multiple color options. Availability is described as pre-order at launch, with different variants indicated by color.
