Our Verdict
Sony WH-1000XM6
Sennheiser HDB 630
The Sennheiser HDB 630 and the Sony WH-1000XM6 are both high-priced portable Bluetooth over-ears, but they each target listeners with slightly different priorities. The Sennheiser prioritize people in search of an extremely balanced sound in a versatile package. Their impressive peaks and dips performance and amazingly well-matched left and right drivers testify to this audiophile focus. On the other hand, the Sony offer superior noise isolation and a better mic, making them a bit more versatile. But the Sony's warm sound profile isn't as well-controlled as the Sennheiser's balanced response.
