These devices are powered by an upgraded QN3 processor and a 12-microphone array, which together deliver some of the best adaptive ANC (active noise canceling) out there. It's powerful enough to block out all the chitter-chatter at a farmer's market and local Starbucks, creating a near-silent listening environment that only the loudest of noise could hope to pierce.Also: The best Prime Day headphone deals: Apple, Bose, Sony, and more deals I'd buy myselfUnsurprisingly, sound quality is top-notch with these headphones boasting Sony's signature warm and smooth sound profile "characterized by minimal peaks and piercing in the higher frequencies," as pointed out by ZDNET Editor Jada Jones in her review. as pointed out by ZDNET Editor Jada Jones in her review.

Call quality is excellent as well, thanks to upgraded beamforming mics ensuring clear call audio.Also: Sony WH-1000XM6 vs. Sennheiser Momentum 5: I used both pairs for months, and here's my pickWhen compared to the previous generation, the design of the Sony WH-1000XM6 received a few tweaks. They're foldable, similar to the XM4 headphones. There is now a dedicated power button to avoid accidental button presses, as well as a more secure fit. Other notable features include a 30-hour battery life with ANC on, Head Gestures (which let you answer or decline incoming calls by moving your head in a certain way), and EQ customization via the SoundConnect app.How I rated this deal As per ZDNET's rating system, I give this deal a 2/5. Sony's WH-1000XM6 headphones take what was already a best-in-class model and refine it even further with minute but impactful changes in key areas. It is worth highlighting that $378 is the lowest these headphones have ever been. Now is the time to buy a pair before the price tag slingshots back. When is Amazon Prime Day?
