These Sennheiser HD 650 headphones offer the listener a warm high-definition sound that is elevated with mid-bass and is very easy on the ears. The Sennheiser HD 650 headphones feature an open and dynamic burst of sound. They are silver and black in color. They fit comfortably on the head and are made with an impedance of 300 Ohms and a frequency response range of 10 Hz to 39.5 kHz. Users will appreciate the warm highs that the Sennheiser HD 650 headphones provide, along with the detailed and accurate bass sound. The cable measures over nine feet in length for increased mobility. Additionally, the Sennheiser HD 650 over-the-head headphones are a reasonably-priced HD headphones solution for users who have a computer with a substandard sound card and do not want to spend a large amount of money on a new sound card or expensive speakers.
