*: Serial Number
*: Photos just in case
*: And most likely boxing
Phone their number and say their headphones aren't working
"Troubleshoot" the headphones, keep with your story because they just don't work
They'll now ask you to return them, you try can push for an advanced replacement but use a drop
Just say you have fucking tinnitus or something that would require you to have headphones/would help to have them
If they still don't let you get an ar, then box them and get them expensive headphones
Good luck
