The two boxes for the different sets of headphones are almost identical, featuring slate grey, high quality cardboard and no product imagery whatsoever: just the company logo and the name of the headphones; front and back.
Both also fold open after you pull away the magnetic lid, revealing a little warranty booklet and a number of extras.
Both come with a neat, little carry case and six extra sets of various earphone tips, some silicon; some memory foam, as well as a clip for attaching to your clothes (to mitigate microphonics) and a 90 degree, 3.5mm converter jack.
The Delta headphones however, also come with a little silver cylinder containing additional tuning filters. These are designed to make adjustments to the sound to make it bassier, more natural or to add more treble. They come in the little silver tube to make them more portable, should you wish to carry a pair around with you for swapping out at some point.
