Treble is lacking a bit. This is the “veiled” sound that people talk about in regards to Sennheiser headphones. Somewhat lacking in air and harmonic content. What is the Sennheiser veil?
HD 600. Many people prefer the more neutral HD 600 over the laid back sound signature of the HD 650. Others like the fact that the 650’s bass has a little more impact and weight behind it.
