What reviewers found
Synthesized across the trust-weighted source mix below.
Across the reviewers we read, the Sennheiser HD 650 is treated as a benchmark for neutral, non-fatiguing open-back sound. sonarworks describes it as "pretty much the most neutral headphones available on the market" while explicitly noting its sub-bass response below 100 Hz is lacking, and homestudiobasics echoes that it is "mostly neutral" but can sound "a bit glossy and overly warm at times." Multiple high-trust r/headphones threads reinforce the picture: owners praise its three-dimensional staging on well-recorded material, its long-session comfort, and its light clamp force, while one detailed thread calls it "still the GOAT." The disagreements are honest and consistent. r/headphones posters note the intimate soundstage can feel "underwhelming" on large orchestral pieces like Hans Zimmer scores, and describe the bass as deep but slightly "papery." The recurring caveat across reviewers is that the HD 650 wants a capable headphone amp to perform its best and is darker/warmer than truly analytical sets.

Taken together, the consensus is that this remains one of the most reliable, well-rounded reference open-backs you can buy, which is why it lands as our best overall despite newer competition.
