9 Scalability
The HD 650 scales exceptionally well with high-quality amplifiers and DACs, improving in sound quality as upstream hardware improves. This makes them suitable for audiophiles who invest in high-end audio equipment.

Designed for extended listening sessions, these headphones feature soft velour pads, a relatively light clamping force after break-in, and large oval earcups to accommodate most ears comfortably.
8 Value
The HD 650 offers great value for its price, often being compared to more expensive headphones. They are durable, have replaceable parts, and their sound quality holds up against higher-end models.
8 Bass
The bass is well-regarded for its depth and control, providing a strong foundation without overshadowing the other frequencies. It strikes a good balance suitable for most genres.
7 Build Quality
Constructed from high-quality materials including metal and premium plastics, the HD 650 is built to last. However, they are known to have a tight clamping force initially, which can be a deterrent for some users.
7 Treble
The treble on the HD 650 is smooth and rolled off, providing a relaxed listening experience free from harshness. However, this character may be perceived as 'veiled' by those who prefer a brighter sound.
7 Versatility
While the HD 650 can be used for various applications like music, movies, and even gaming, its sound signature is best suited for less aggressive genres due to its warmer tone and relaxed treble.
6 Amplifier Dependency
The HD 650 has a high impedance of 300 ohms and truly shines when paired with a good amplifier. Using it without proper amplification can result in less impressive sound quality.
