Sennheiser IE 600 In-Ear Monitoring Headphones - 508948

In-ears that hit the sweet spot

These traditional wired in-ear monitors (IEMs) are among my favorite headphones released this year. Sennheiser designed the IE 600 earbuds to split the difference between the punchy fun of their IE 300s and sharp technical prowess of the IE 900s. And to my ears, they nailed the sonic sweet spot. 

Like those other two models, the IE 600s feature a single dynamic driver inside each earbud. They also share a similar ergonomic earbud design — made of amorphous metal this time around, 3D-printed into shape and hand-finished. The result is a durable, comfortable set of IEMs, tuned for an engaging, musical sound profile with a delightfully prominent midrange.
