Most top of the line headphones come with a luxurious packaging.
Which headphone do you consider to have the best looking/useful packaging.
The Blox M2C earbuds came in what I consider the best packaging. Looked decent (non-cheap but simple), just big enough to comfortably fit the product inside and no wasted materials on extras.

The Panasonic RP HTF600-S packaging looked fancy but it tore up my hands.
The Superlux HD681 comes with really simple packaging that I think looks nice. It looks like headphones you would buy at the pharmacy, though.
I agree with this. It really surprised me when I got it just how nice and solid the packaging was, also surprisingly large.
