My trusty Sony WH-1000XM2 headphones were still going strong after years of use, but the ear pads were worn out. I definitely kept them too long. I'd had great results with Brainwavzs before when they turned my Audio-Technica BPHS1, from an instrument of torture with the stock pads to sublime headphones so I thought I'd order some replacement pads for my Sonys. The pads are great quality and installing them was very easy as they are clearly designed to be replaced. The cost of the pads relative to the overall cost of the headphones is tiny. With the new pads installed the headphones are comfortable again and look presentable. If you are thinking about replacing your pads with Brainwavz, stop thinking and just do it. You can thank me later.
