The ear cushions do not fully correspond to the original (and headphones: Sony MDR CD550), I got but they raised and they can be used. The material is indeed soft, but caused friction noise. The build quality is in itself quite good, but not perfect. One ear pads was sewn wrong. There is a seam failure. However, it falls within the ambit and the ear cushions sit on the headphone shells. Because it is very difficult to spare earpads raise for Sony MDR CD550, I am still grateful for this earpads. Although the quality is not very high, but it is also the price quite reasonable. At least the headphones can be used again. Although the earpads play in the lower league than headphones, but are better than nothing. The old original have now fully resolved. I think it's the way a great pity that Sony itself does not offer replacement ear pads! This fact keeps me back, the company SONY to consider when buying decision for new headphones again. Now I have Sennheiser HD 650, and find them sonically much better. However, they are open. Closed headphones as a replacement for Sony MDR CD550 I have not yet found. Thanks to new earpads I can but first use the Sony MDR CD550 now on.
Incidentally, I have now found a replacement for the headband padding tape my Sony MDR CD550:
Beyerdynamic pillow leatherette new version Black leatherette upholstery with head pressure buttons Article number: 990 681 For: DT770 DT790 DT797 DT880 DT770M DT770PRO DT770PROHT DT880PRO DT880PROHT DT990 DT990PRO MMX 300, 2nd generation [...] Costs about 7 euros.
I have it selling music equipment from the German online shop and with "T" begins in the name.
For installation I had to cut only on the sides a little, and I got even wedged in the removable side panels there. The old padding I had to completely remove. But it was already totally all. The comfort is very good. It looks visually somewhat strange, or perhaps simply unfamiliar. But I'm super happy. Especially for the price! Perfectly. Now I can take full advantage of my old Sony again. Thanks to Beyerdynamic for as cheap and good replacement pads! Power but please times the earpads for Sony, which do not cause friction noise! ;-)
