Sony IER-M9 IEM

A high-end IEM for music enjoyment and monitoring alike, the Sony IER-M9 is built with the company’s proprietary Penta five-driver system, which includes a magnesium-diaphragm super tweeter and optimized signal paths. The T-shaped balanced armature directly drives the diaphragm for a more linear motion and clean, faithful highs. Of course, the IEM has an upscale look to match, with a light, durable magnesium alloy housing and a carbon fiber plate. Designed to stay firmly in place with a snug fit for all ear sizes, it comes with a variety of ear tips, a carrying case, and other accessories. 

Head-Fi user Kygreying says, "The IER-M9 is an incredibly technically proficient IEM that does very little wrong, beating out many of the competition at this price point (including CIEMs). It is presented in a very professional packaging, and the sound is excellent. It handles almost all genres with ease, aided by solid performances across the board, with fast and quick response, stellar imaging, and plenty of details.”
