Price is not negotiable. Headphones were used for like 2-3 months while I was working a job. Haven’t used them in probably half a year or more. Nothing is wrong with them, I just don’t need them anymore. About the headphones: These headphones are fantastic. Easily the best sounding over-ears I’ve EVER heard. Save for even more expensive options, you won’t find anything better sounding than these. And the noise cancellation is second to probably only Apple. Aside from the AirPods, the noise cancellation is best in class. I’ll be sad to see them go but like I said I haven’t used them in months so I guess someone else can find better use as opposed to them sitting and collecting dust. The little white packet is an anti-moisture pack (silica gel, basically). I swap it out once a month to make sure it’s fresh and working. When you purchase the headphones I’ll put in a new one regardless of when I last swapped it out.
