40mm Neodymium Driver. With 58 ohm impedance, the SMH-500 headphones work great with both low-powered devices and amplified sources. They offer less than 5% distortion at 1 kHz with a sensitivity of 101 dB ±3 dB.

10-foot Coiled Cable. The attached coiled cable gives you plenty of room to work with. It has a standard 1/8" miniphone connection.

Refined EQ Curve. The headphones are designed with an EQ curve that’s been tailored for an enhanced low end that allows engineers to detect rumble and monitor bass frequencies effectively. The excellent high-frequency response has been enhanced to accurately and clearly reproduce spatial detail. There’s also a slight bump in the midrange to maintain focus on vocal and dialogue intelligibility.
