The Sennheiser HD 820 are closed-back stereo over-ear headphones offering detailed and accurate audio reproduction for audiophiles, mixing and mastering engineers, and music aficionados in studios, listening rooms, and on the go. Their closed-back design delivers up to 26 dB of passive noise cancellation and incorporates concave glass covers, which reduce resonance by reflecting sound to a dedicated absorber. Sennheiser's dynamic Ring Radiator transducers provide a maximum SPL of 103 dB and a wide frequency response of 12 Hz to 43.8 kHz. Handcrafted microfiber ear cushions and a sturdy metal headband with an internal damper offer comfort and stability during wearing. A 10' impedance-matching cable allows distance between you and your headphone amplifier, while balanced 4.4mm and unbalanced 1/4" plugs enable versatile connectivity. The HD 820 headphones ship with a microfiber cloth and a storage box for simplified transport.
Choose between open-back (spacious sound, leaks noise) and closed-back (isolating, punchy bass) designs based on your environment. For wireless headphones, prioritize comfort and Active Noise Cancellation (ANC) performance. Available from $2,199.95.
Wired headphones have no ongoing costs besides occasional earpad replacements. Wireless headphones function as consumables, as their batteries will eventually degrade after a few years of daily use.
