Buying replacement pads for the Sennheiser HD650 can be tricky. Outside the direct replacement from Sennheiser, most replacements impact the sound tuning negatively. Every replacement set I have tried has been a failure; until now. The Brainwavz replacement pads are nearly identical to the OG ones provided by Sennheiser! This is a welcome relief as Sennheiser Pads tend to wear out after a year due to their construction. The Brainwavz pads are just as plush, padded, and comfortable as the originals with a significantly better value proposition. I wasn't sure what to expect from these pads, but upon their arrival, it was clear that these were as good, if not better than the original.If you are looking for replacement pads for your Sennheiser Huh Duh Six Hungeos, then look no further. For the price, I will be buying a couple more sets to future-proof my headphones for many years to come.FYI: The second photo shows the HD6XX with original pads from Sennheiser while the HD650 are using the Brainwavz replacement pads.
