Koss KEB40 In-Ear Headphones

Despite their compact size, Koss' KEB40 in-ear headphones pump out the kind of bass you hear when a whale sighs. This depth starts with three sizes of silicone tips that let users find a form-fitting seal to isolate the most noise. Once the headphones are in place, their micro monitor and isolation rings heighten bass presentation, giving music deeper beats and rendering all audio books in the voice of James Earl Jones. Dynamic 9 mm drivers capture frequencies of up to 20kHz so the mid-range and treble show resilience against the bass. Beyond these sound-enhancing features, Koss adds a solid machined-aluminum body for durability and a cord slider for preventing tangles.
