Sony 1000X The CollexionNo score yet
Marshall Milton A.N.C.

Gaming performance
Sony 1000X The Collexion
1.5

Sound leakage
Sony 1000X The CollexionNo score yet
Marshall Milton A.N.C.
2.8
Sound leakage becomes noticeable at higher volumes, and the on-ear fit allows outside sound in as well. This is a format tradeoff rather than a minor edge case.
Ownership and support

Sony 1000X The CollexionNo score yet
Marshall Milton A.N.C.
3.7
Configurable auto-off timers help prevent idle drain. One reviewer also observed brief adaptive-ANC dropouts, suggesting some power or mode behavior still needs refinement.
Comfort and build
Sustainability materials
Sony 1000X The CollexionNo score yet
Marshall Milton A.N.C.
4.9
A large share of recycled material gives the construction meaningful sustainability credentials rather than a token eco claim.
