The WH-1000XM4C is worth considering if its offer lowers the cost of this headphone class; the WH-1000XM6 fits buyers who need its documented connectivity options. We do not name a noise-cancellation winner without matched testing. XM4C is a distinct model: original XM4 specifications should not automatically be transferred to it.

Small differences and useful differences
Sony’s manuals put these models approximately one gram apart. That cannot tell you which is more comfortable. Published full charging times differ too, but depend on the adaptor and conditions. Wired impedance is a technical specification, not a sound-quality score. For daily use, try the fit and check which connections you need.

How to read the reviews
What Hi-Fi and Gizmodo publish XM4C reviews. Their assessments provide context for that model, but are not a joint measurement by AnalyticPicks. The XM6 manual confirms SBC, AAC, LDAC and LC3: check your source device before paying for a codec you may not be able to use.

Frequently asked questions
Does one gram less mean more comfort?
No. Fit, cushions and wearing time matter more to that decision than such a small difference.
