What is Headcase?
Headcase is an evidence-backed headphone case compatibility index. Every fit shown on the site has a traceable source — a seller listing your headphone by name, an owner photo, or a dimension-verified match. Dimensional guesses and unverified claims are not published.
The index currently covers 278 headphone models across all major brands, 51 cases, and 7,300+ published fitments. Model pages show every compatible case with the evidence type that backs it. Case pages show every headphone confirmed to fit, ranked by evidence depth.
Read the fitment methodology to understand how evidence is collected, scored, and published.
