The Sennheiser HD 490 Pro studio headphones serve up the optimal mix of sonic clarity, wearing comfort and reliability - everything you'd expect from a Sennheiser design. These headphones have been built to handle the complexities of contemporary music production, so you can expect the fully uncoloured response that supports honest yet dynamic audio reproduction, alongside fully retained definition, fullness and accuracy. Meanwhile, the open design adds a more spacious dimension to the sound and ensures improved comfort, even during longer listening sessions. Clarity, Reliability & Comfort Comfort and wearability are just as essential as sound quality and, as such, Sennheiser have given the Sennheiser HD 490 Pro headphones a flexible and lightweight design that effectively eliminates any pressure points, completing a more ergonomic fit. Two pairs of ear cushions (one set designed for mixing and one set designed for production work) have been included and can even be washed after more intense production sessions and, when they eventually wear out, can easily be replaced. Designed for Complex Music Production To ensure the best and most detailed, clear audio reproduction possible, these headphones feature Open-Frame Architecture, where distortion and resonance is no longer an issue, resulting in nothing but highly accurate sound. Neodymium magnets boost both the performance and efficiency while the extremely lightweight voice-coils don't only improve the wearing comfort but support a more authentic and dynamic level of audio reproduction. Finishing in pro-grade Sennheiser-style, the HD 490 Pros also feature a patented cable design that blocks any possible noise caused when the cable is moved.
