Last year someone gave me a pair of Sennheiser headphones—dead ass gave them to me. I was ballin’. I got to be a homeless person with an iPhone 12 and a pair of Sennheisers. And then my idiot friend set off a series of unfortunate events that resulted in the loss of my headphones, along with everything else I owned at the time.
So last month when this very sweet devout Christian saw a comment of mine about being a homeless drug addict, and sent me $300. I bought a new pair of Sennheisers on Mercari. I’m pretty sure it was the same model even.
I finally got around to checking my mail and—the headphones are fucked off. They won’t pair or fucking anything.
I had to fight the screaming urge to slam them on the ground.
No joke, reach out to their customer support and see about getting them replaced. I got a pair that was defective (to replace a pair on warranty) and sent it back and got a working one.
Yeah, Sennheiser is usually quite generous with their warranties, one of the better companies in the audio space for it.
This would be my suggestion as well. Sennheiser should take care of you.
