I originally bought my Sony MP3 player about 3yrs ago and was astounded at how difficult it was to pick up a decent docking station for it, so I dug deep into my pocket and treated myself to this little fellow last year. I really can't find anything bad to say about it! The sound quality is amazing!
I did read a few reviews myself before buying which said things about the volume not going load enough, well, believe me, it is, I have had no problems at all with the sound level. Also I read a review that said about the remote being a bit useless, well, I do kind of understand this statement as you can't got into different folders on your mp3 player (this might be different for different mp3 player models) but volume control and turning off and on are handy to be able to do at a distance!
I love it, I don't know want I would do without it now, and I would suggest to anyone to get one to go with your Sony Mp3 player.
