Sony Launches New Pro Audio IEM, the IER-M500

Several weeks ago, I had a meeting with a Sony representative who informed me that Sony Pro Audio would be launching their first-ever Pro Audio IEM. While Sony Pro Audio has been a staple of the Pro Audio community for many years with their popular microphones and headphones, they felt it was time to enter the growing world of stage and studio IEMs with an entry-level offering, the Sony Pro Audio IER-M500. Ringing in at a mere $119.99 USD, the IER-M500 boasts a frequency response of 10Hz to 40kHz with a focus on noise isolation, durability, and a comfortable and stable fit for long, energetic stage performance.

Features include a fully sealed structure for better sound insulation. Special ear tips that employ a proprietary polyurethane foam material for suppression of external noise, especially in the high-frequency range, with a thinner wall thickness to better conform to the user’s ear shape, again for a better seal and extended comfort. The dynamic driver is surrounded by a large rear chamber with “balanced ventilation,” and a multi-layer structure is employed for high-frequency control. Special ear-support devices are provided in five different sizes to securely hold the IEMs in place. The detachable cables employ a proprietary water-resistant connector.

For accessories, the IER-M500 includes a Carry Pouch and a special retention clip for attachment to the user’s clothing, further securing the IEMs for active performance.

The Sony Pro Audio IER-M500 comes in three different color schemes, Red right/Blue left for easy channel determination in dark and chaotic environments, clear with red and blue accents for a minimal presentation, and black with red and blue rings.

Weighing in at a slight 6.9 grams, for maximum efficiency, the Sony Pro Audio IER-M500 has an impedance of 16Ω and a 103dB sensitivity.
