3:59GOD TIER HEADPHONES? Worth It? - Sennheiser HD 650 Review
The reviewer finds the Sennheiser HD 650 to be exceptional for music, calling them the best-sounding headphones they've tried, with strong mid and low-end, good treble, and great instrument separation. However, they criticize the heavy clamping force and weight, which cause discomfort during long sessions, and note a narrower soundstage compared to other open-back models. Overall, they recommend them for serious audiophiles who can tolerate the fit, but not for gaming or extended wear.
