I recently purchased the Beyerdynamic Headphone Adapter Screw M5, hoping it would be a perfect fit for my DT 770 Pro headphones. Unfortunately, it doesn’t fit these headphones, which was a major disappointment. The product itself seems to be well-made, with solid construction and quality threading, but the lack of compatibility with one of Beyerdynamic's most popular models feels like a significant oversight.
If you’re considering this for DT 770 Pros, save yourself the frustration—it’s not compatible. However, if you're using a different Beyerdynamic model, it might work, but double-check before buying. I wish the compatibility details were more clearly highlighted in the product description. Overall, a solid part, but not useful for my needs.
