I own a pair of Sennheiser HD650 headphones. Mine are an early pair, bought around 20 years ago. They don’t see much use these days since What Hi-Fi? tests so many headphones, and there is always something new to listen to. Regardless, I still dig out the Sennheisers every once in a while, just because I like the way they sound.
The last time I did that, I noticed that the earpads and cloth-covered headband pads felt soft and had lost their shape a little. I Googled these things, as you do, and was surprised at the sheer quantity of replacement options available. I could buy the official ones from Sennheiser, of course, but there were a huge number of cheaper alternatives from third-party companies.
