Sennheiser HD 490 PRO vs Sennheiser HD 490 PRO PLUS
The HD 490 PRO and HD 490 PRO Plus are the same open-back reference headphone for mixing. What changes is what comes in the box.
Which one to choose
They share the 38 mm dynamic driver, open-back design, 130 ohm impedance and the same response, so they sound identical when mixing. The Plus adds accessories, such as a carrying case and an extra cable, which help if you take your headphones from studio to studio. If you always work at the same desk, the HD 490 PRO is the sensible buy; if you move around or the price gap is small, go for the Plus.
