Sennheiser HD 600

Pros

• High-quality, lightweight plastic construction that is noted for long-term durability
• Excellent clarity and detail retrieval for its price point
• Highly adjustable fit that accommodates a wide range of head sizes
• Exceptional long-term comfort for extended listening sessions

Cons

• Noticeable lack of sub-bass extension and 'punch'
• Narrow soundstage compared to other open-back competitors
• Strong initial clamp force (though it can be loosened over time)
• Instrument separation can be outclassed by more modern or higher-end designs

Caveats

• Users have noted minor aesthetic and material changes over the years, such as transitions from 'marble' finishes to newer matte or glossy designs
• Bass performance is often described as 'unbearable' for those accustomed to the extension of IEMs or bass-heavy headphones without EQ
• Earpad wear can significantly impact the sound profile, requiring fresh pads to maintain original performance

Best for

• Critical listening and vocal-centric music
• Studio tracking and professional audio reference
• Users seeking a 'forever' headphone with high reliability and parts availability

Avoid if

• You are a 'basshead' who prioritizes deep sub-bass and impact
• You want an expansive, wide soundstage for gaming or orchestral music
• You prefer a more modern, metal-heavy industrial design
