Sony B153 volume tunning.
Is it possibleto get access to the service menu in these models? Allowable range of volume doesn't seem to be enough for me. While travelling, music is supressed by the external noises. I also changed the original earphones of Sony (included in the product) to Philips headphones (in terms of quality) what reduced the volume once again.
Although the sound quality it gives is okay, the volume restriction is a mistake. Has anyone come up with any solutions so far?
