Sennheiser HD 650

I purchased the Sennheiser HD650s as I was looking for a set of open backed headphones with a neutral frequency response. After reading a lot of reviews and opinions I was convinced that this was the best choice in this price range and I have not been disappointed.

The sound is beyond anything I have experienced before, even while being driven from my Mackie audio interface's output. While the impedance of these headphones is high (300 Ohm) they are still fairly easy to drive, so do not feel pressured into buying an amp before trying them on your current setup, even my laptops inbuilt sound card could drive them to a satisfactory volume.


These are the most comfortable headphones I've ever owned and I have regularly worn these through long production sessions and work days. After the first couple of weeks, the clamp force reduced and they are very secure and light.

To note: The first set I purchased had a defect in the cable connection and Thomann was quite responsive, despite the brexit shipping disruptions and replaced my set within a month. The version currently being sold is produced in Romania not Ireland doesn't come with a storage / carrying box.

To conclude, the clarity and reproduction of these headphones is fantastic, even after 15 years in production, they are still competitive, truly an eternal sound!
