Can you just return them?
Did you purchase new or used?
Grado Customer Service (Bad)
I decided to try out some Grado headphones and boy do I regret it.
I received them last week, (Feb 14th, 2024) and immediately connected them into the headphone jack and realized there was a problem with the 1/8" mini stereo plug. It was loose and the stereo image would collapse between mono and stereo and everything in-between.
I tested the Grado SR 325X headphones on three different systems and I had the same problem which I don't have with my other headphones.
I let Grado know right away and had to wait a long time for a response. I explained everything and it sounded like they didn't believe me. They basically told me that this doesn't happen and somehow made it seem like my fault.
I asked for a label and they still haven't got one out to me and it's been five days now since my initial email to let them know something was wrong.
This has been a horrible experience and I went from wanting to exchange them for a working pair to just wanting to return them back now. I won't buy another Grado product ever based on this experience.
Just a heads up for anyone considering Grado.
