Today's Dealmaster is headlined by nice discount on Sony's WH-1000XM4, as the high-end wireless noise-cancelling headphones are currently down to $278 at various retailers. That's more than $70 off Sony's MSRP, about $50 off its typical street price online, and tied for the largest discount we've tracked to date, which we also saw on Black Friday.
