Hi everyone, normally I'm just a silent reader here. I want to ask for advice.
I bought Sony Headset WH-1000XM4 at Officeworks on January 2021. I normally used it just about 1-1.5 hours per use, no issue. Until recently due to my work requiring using the headset for longer time like 2-3 hours, I notice after prolonged use on the left side of the earcup where the sensors are, there is like static/wind/crackling noise similar like in this video
It annoyed me and it keep crackling until I have to turn it for like 2-3 hours later to be normal again. It keeps happening when I use the headset for long use time, like minimum 2-3hours use it showing again the annoying sound. Another issue is the auto shutdown system is not working anymore so I have to turn off the power button. I Google search those issues, many people has similar problem so it definitely manufacturer defect right?
Now about the warranty today, I went to Officeworks, I was hoping they can replace or at least service my headset. The manager there straight away rejected my warranty claim explaining that I am out of warranty since it's more than 12 months? He argued since I am not buying their premium extra warranty cover, my warranty is only for 12 months (I used the headset 1 year 8 months)
I thought premium headset like Sony XM4 has 2 years warranty? It is expensive headset not like cheap one. Can I complain to ACCC about this issue? Anyone has similar experiences? Any advice what should I do?
Thanks
