These Sennheisers are a solid choice for engineers and musicians needing reliable isolation and protection while tracking or mixing. The ActiveGard feature is a real lifesaver, and their relatively low impedance means you won't need a dedicated headphone amp. They're not going to blow you away with a warm, musical sound, but they’re accurate and dependable for critical listening.

Frequently Asked Questions
