Full product profile Official image
Exact model & source notes

The HD 599 (article 506831) is an open-back, over-ear wired headphone that Sennheiser describes as topping its 500 series, in an ivory finish with brown headband stitching. It has a 38 mm transducer with Sennheiser's E.A.R. (Ergonomic Acoustic Refinement) design, which Sennheiser says channels the audio signal directly into the ears, a 50 Ω impedance and soft replaceable ear pads, and comes with two cables — 3 m with a 6.3 mm plug and 1.2 m with a 3.5 mm plug. Sennheiser gives its weight as 250 g and explicitly lists active noise cancellation as False.

THE DIFFERENCES, MADE VISIBLE

Visual facts

Differences first. Select a topic for its graphic, sources and conditions.

How to read this comparison
  • Manufacturer facts for the exact models shown. Not a quality rating or a test result.
  • “Different” means the known values differ, not that one is better.
  • Missing or conflicting evidence is marked and never counts as a difference. Source chips hold each fact’s sources and conditions.
FEATURES SIDE BY SIDE7 topics

Yes and No describe the listed feature. Missing evidence stays unverified.

SELECTED TOPIC
01 / 07

Impedance

Nominal electrical load, not sound quality or loudness. Output capability and headphone sensitivity matter together; impedance alone cannot decide whether an amplifier is needed.

Explore the full specifications

Start with your listening environment. Open and closed earcups suit different surroundings. A closed back is not the same as active noise cancellation. Check the exact cable and headphone output. We do not turn impedance, driver size or unpaired lab results into a sound-quality score.
