Top Wireless Headphones: Sony WH-1000XM6 vs Sennheiser HDB 630

Sennheiser's HDB 630 enters the roundup as a higher-resolution alternative with 60-hour battery life and lossless audio over USB-C. For buyers, the decision now sits on ANC chip generation versus wired lossless playback and endurance metrics. Related coverage from RTINGS.com tracks noise cancellation specifically, while Technobezz shifts focus to TV sound bars.

ANC and driver architecture

The WH-1000XM6 pairs Sony's QN3 processor with 12 active microphones, an increase from 8 in the M5. Engadget's tests report improved suppression at medium and high frequencies, including human voices. Driver hardware was replaced, with mastering-engineer input on tuning and spatial audio upmixing added to the feature set. Speak-to-Chat lowers volume and engages ambient mode when the wearer speaks, and the system switches noise-cancellation profiles based on location or detected activity.

The HDB 630 takes a different route. Sennheiser ships a USB-C dongle enabling 24-bit/96kHz wireless transmission, with lossless playback also available over a wired USB-C connection. The headphone pairs that pipeline with a detailed EQ and a Crossfeed circuit that blends the left and right channels for a more natural stereo image. Where the M6 leans on silicon and mic arrays, the HDB 630 leans on the DAC chain.

Battery, weight, and pricing

Sony rates the M6 at 30 hours with ANC on, unchanged from the M5. Weight is 0.55 pounds. The HDB 630 doubles the headline figure to 60 hours with ANC active, falling to 45 hours when high-resolution tracks are enabled. Sennheiser's headphone weighs 0.68 pounds. The M6 lists at $450, a $50 increase over the M5's full retail. Sennheiser pricing was not specified in the source material.

Color options diverge as well. Sony offers the M6 in Black, Platinum Silver, and Midnight Blue. Sennheiser ships the HDB 630 in Black only. Neither pair carries a water-resistance rating. Both support multipoint pairing and Bixby, Siri, and Google Assistant.

The call

The data favors the M6 for buyers prioritizing ANC performance, microphone count, and ambient-mode behavior. The HDB 630 is the measured pick when lossless USB-C audio and extended battery life outweigh ANC tuning.
