The Sennheiser HD 420 is a pair of over-ear headphones that were introduced in the late 1970s, primarily aimed at providing a comfortable listening experience with a focus on sound quality. The design features a lightweight construction with plush ear cushions and an adjustable headband, making them suitable for long listening sessions. The headphones employ dynamic transducers to deliver clear and balanced sound across a wide frequency range. The open-back design contributes to a more natural soundstage, allowing for a spacious and immersive audio experience. The specifications for the HD 420 include an impedance of 600 ohms, a frequency response range from 10 Hz to 30 kHz, and a sensitivity rating around 100 dB, which means they can produce a strong output while requiring minimal power. The HD 420's build quality typically emphasizes durability and comfort, appealing to audiophiles and casual listeners alike.
