Enlarge (credit: Ars Technica) The Dealmaster has finished streaming Dune, so it's time for another round of the best tech deals from around the web. Today's rundown is headlined by the lowest price we've tracked for Sony's WH-1000XM4 headphones, which have fallen to $248 at various retailers this week. That matches the deal we highlighted during Amazon's Prime Day event and marks a roughly $80 drop from the noise-canceling pair's usual online going rate over the past few months. We've recommended the XM4s on several occasions in the past, and they remain an excellent blend of high comfort, useful features, and top-tier noise-canceling strength.
