The HS35 comes in a bright yellow box with a picture of the headset on the front which is number one on the Corsair packaging handbook. So this will go perfectly with the rest of the yellow Corsair product boxes in a retail display. Beyond that, the front of the box has the model name down in the bottom left corner along with a Discord certification showing in the bottom right. The only real information is the list of devices this works on in the top right corner which covers PC, Mobile, and all three gaming consoles. Around on the back of the box, Corsair does give a little more information though. They have a short 4 feature list repeated a few times in multiple languages as well as a specification listing again repeated in multiple languages. They basically point out the memory foam earcups, tuned 50mm audio drivers, detachable microphone, and the volume and mute controls on the headset. Speaking of those the picture on the back of the box is zoomed in on that portion of the headset.
Inside the box, the HS35 comes packed away in a formed plastic tray with a plastic strap across the top. I like this better than using twist ties to keep the headset in place as most do. You get a warranty guide as the only documentation. Then there is a small plastic bag which has the detachable microphone and a single mobile style plug to dual microphone/headphone plug adapter for PC use.
