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.

Open-back design
Open-back earcups are not sealed. Start here if your listening space is quiet; this construction is not a sound-quality rating.
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.
The reviewed exact sources do not explicitly establish active noise cancellation absence. Preserve separately sourced acoustic design and passive attenuation; they cannot turn omitted ANC into a false capability. · Manufacturer specification
The reviewed exact sources do not explicitly establish microphone absence. Omission from a package or technical inventory, a stereo audio connector, and a without-remote statement do not establish microphone=false. · Manufacturer specification
Evidence is missing or conflicting on at least one side. This is not a verified difference.

Sennheiser HD 600
Sennheiser's manual and UK specification table list a 3.5 mm plug with a 6.35 mm adapter, while the UK page's connection text describes a 6.3 mm plug with a 3.5 mm adapter. Check the listing for the supplied plug. · Manufacturer specification · Needs a matching headphone output; the 4.4 mm balanced cable needs a balanced output.
Manufacturer claims do not establish independently measured performance, current retailer stock or price. Unlisted specifications remain explicitly unknown.
The open-back design leaks sound and lets outside noise in. Sennheiser's pages disagree on whether the cable ends in a 3.5 mm or 6.35 mm plug, so check the listing.
