Verdict
The short version
In this Sennheiser HD 650 review, I share my experience with these remarkable open-back professional headphones. Known for their rich, natural, and clean sound output, the HD650 outperforms others in its class. Paired with a reliable amp, their performance is exceptional across a variety of genres, the soul of music delivered straight to your ears. While they do slightly falter with complex audio without an amplifier, their performance ratio and overall sound quality make them well worth the investment.
