The HD 650 first appeared on our recommended list for Open-Back Headphones in June 2017 and it remains on that list today.

It was also on our recommended list for Studio Headphones from February 2018 until February 2020.


Sennheiser HD 650 are based on the HD 600, along with improved features.

Aside from their lightweight aluminum voice coils made for smooth transient response and magnet systems for minimizing distortion, they have elliptical designed ear cups that fit comfortably on ears.

These also have a detachable cable that’s made from highly conductive oxygen-free copper made for low handling noise.

These are a great investment if you are looking for high-resolution headphones for referencing, mixing or high fidelity equipment.

From “The Best Open Back Headphones for Mixing and Mastering”

The HD 650’s are studio headphones designed for audiophiles, with near-neutral sound that makes them quite useful for mixing and monitoring.

The aluminum voice coils of these headphones ensure fast transient response across the frequency spectrum. They provide detailed sound reproduction and low harmonic distortion which makes them suitable for referencing. The detachable oxygen-free copper cable also allows low handling noise sensitivity.

The lows, mids, and highs have noticeable detail, making these great for reference, and allowing for better informed mixing decisions. On the flip side, the soundstage is a bit limited, and the relaxed midrange might cause some to up the level of vocals in the mix more than they should.

Its large elliptical design and velour ear cups allow for a more comfortable fit, which together with its open-back design make it ideal for long sessions and for leisure listening.

Compared to its similar looking sibling the HD 600, the HD 650 steps it up with better bass definition and a slightly relaxed midrange. If you feel that the HD 600’s frequency response would be too flat or neutral for you, or if you want studio headphones that are more hi-fi sounding the HD 650 is a good pick.
