This is the kind of headphone that will last you for years beyond its generous two-year warranty. And should you ever break something, Beyerdynamic offers a comprehensive list of spare parts for most of its products, though we could only find cables for the DT 700 PRO X. Listeners who don’t intend to take their headphones out of the house should look into the open-back variant, the Beyerdynamic DT 900 PRO X.
