Differences first. Select a topic for its graphic, sources and conditions.
Yes and No describe the listed feature. Missing evidence stays unverified.
Open-back earcups are not sealed. Start here if your listening space is quiet; this construction is not a sound-quality rating.
Closed-back. Manufacturer specification
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.
4 verified differences, most decision-relevant first. Missing information stays separate.
