Sennheiser HD 480 Pro vs Sennheiser HD 480 Pro Plus
The HD 480 PRO and HD 480 PRO Plus are the same closed-back studio headphone. What changes is what comes in the box.
Which one to choose
They share the 38 mm dynamic driver, closed-back design, 130 ohm impedance and the same response, so they sound identical: both isolate enough to record in the same room as an open microphone. The Plus adds accessories meant for daily use, such as transport and spares. If you always work in the same place, the HD 480 PRO; if you carry them around or the price gap is small, the Plus.
