Its going to be a month, I am using this mp 3 player from Sony and am happy with it. I am a fan of sound produced from Sony products and wanted a Sony brand mp 3 player. 2 GB storage is enough for my selection of songs, so didnt go for the 4 GB version.
So, talking about the features it has a play/pause button and encircled by a led light and a dial. The dial is used to play the next/prev track and the led is charging light as well as syncs with the beat of the song being played.
A dedicated record button is present along with a zap in button. The zap in cycles the song one by one in the playlist playing each song from middle for a few seconds (you can consider it like a preview mode). The "zap in" button doubles up as the bass button on long press which adds extra bass instantly.
The sound quality is obviously great (as a product of Sony, nothing to say about it) and it is loud enough that you cant hear loud music at full volume. However it never gets distorted and the ears never pain. You can enjoy it for hours.
However, there is one problem with sound arrangement. It does not list the songs with their titles but with their file names. Its creating problem for me searching for the song I want. Also, I usually prefer single- handed use and I face problem while playing the next/prev track as I have to hold this with one hand while dialing for the next/prev track.
And as far as battery backup is concerned, I get a 5 days backup with around 3 hours per day on an average.
At Rs. 2, 600/-, its a bit pricey, but for peoples who appreciate good sound, they would not feel depressed after investing their money in this.
