Yes the Sony hybrids are very comfortable but from my experience, it attenuates the highs and accentuates the lows. The Phonak PFE tips are just as comfortable and does not change the sound character as much as the Sony hybrids for me. They're a little hard to come by and pricey too. Looks like earphonesolution is the only one that stock them. Phonak Audeo company (headphone division, hearing aid division is still oeprating) has closed down some time back.
