Earpads for Sennheiser PC38X & More - WC FreeZe Cooling Gel

Nice and comfy

Fit sennheiser hd620s well and feels good

As advertised, these snap in perfectly like the originals. That said, I do however feel there are areas lost due to the increased thickness & materials. The 1st is the thickness. These hardly compress at all an apply more side pressure on the jaw/cheeks than the original. After a few hours this is a discomfort, even after a more loose adjustment to the headset which segments to my next issue. A head forward or back motion causes these to slide forward/back even for a properly secure headset adjustment. Next is sound quality, the sound is noticeably different with clarity, treble, & bass being muffled out & more quite. And lastly the cooling gel effect is nice, but very quickly dissipates. After about 10-15 minutes the effect is entirely gone an unnoticeable. After half & hour to an hour these lock in heat an cause sweat. The material just locks heat & doesn’t have good breathability. I’d rather these use a different fabric/material altogether as the material now doesn’t perform well.
