128 sounds very ragged to me. It's fine for the car or background music
but when I put on my Grado headphones the lossy compression is not
really a pleasure to listen to.

This:
"Audio (MP3)
32 kbit/s – MW (AM) quality
96 kbit/s – FM quality - This is questionable since FM broadcast is
transmitted in analog 30hz-15khz. Similarly one cannot compare directly
an LP record to CD using kbit/s.
128–160 kbit/s – Standard Bitrate quality; difference can sometimes be
obvious (e.g. lack of low frequency quality and high frequency "swashy"
effects)[citation needed]
224–320 kbit/s – VBR to highest MP3 quality"

At 225 kbit, it is strange it is so offensive to your ear, it is
approaching concert hall quality ... 96 kbit is ~equal to fm radio ... I
think what your are hearing is more in your mind than anywhere else.
