Sennheiser’s HD 599 sit in the brand’s home listening range, pitched as a step up from entry-level wired headphones and competing with other open-back HiFi staples from the likes of Audio-Technica and Philips. This listing is refurbished, which typically means the headphones have been returned or previously used, then inspected, fully tested and restored to proper working order, with any cosmetic marks usually minor compared with heavily used kit.

Who are the HD 599 best for?

Go for these if you listen at home and care more about a natural, spacious presentation than isolation. The open-back design lets sound breathe, which can make instruments and vocals feel less boxed-in, but it also leaks audio and lets outside noise in, so they are not suited to commuting or shared offices. The around-ear fit is aimed at longer sessions, and the wired connection keeps things simple for plugging into a HiFi setup, DAC or headphone amp.

  • Open-back tuning: wider soundstage for music and films in quieter rooms
  • Around-ear design: comfort-focused for extended listening
  • Wired HiFi use: best paired with home audio sources
