Sennheiser HD 650
A pro-tier open-back reference headphone at 300 ohms, prized for a natural midrange in critical-listening and mixing work. The open design and even mids make it a long-standing studio reference. Two limits: open-back bleed rules out tracking, and the 300-ohm load needs a dedicated amp, not a phone output, to perform properly.
