Philips GoGear Mix- 2GB I had bought this mp3 player 3 years back and has been using it extensively during travelling.
The device is quite small almost 3 inch length with 1 inch display which shows the current song and has a song advance bar.Being such a small device can be easily kept in the any pocket while walking or bag pouch.
The rest 1 inch is the four navigation way key to navigate through playlist, select song.and various features like Folder View, Setting- sound, shuffle songs, manage playlist, equalizer with various preset and manual, control sound.everything can be controlled and manged through single key.
The device comes with a very powerful and reliable battery had been using it very roughly last 3 years and still last for a full day(10 hours of playback) if fully charged.
Philips GoGear Mix comes with headphones which has superior quality sound and any kind music will be a pleasure to hear at full volume.
I also use it as a pen drive to transfer data.No USB cables needed.
Go Gear also has additional music option- DIGITAL FM Radio.simply tune in the station and preset the station.Can preset about 30 radio stations
It also has as a voice recorder .and can be done so while we listening to music anywhere anytime.
If you looking for a rough and tough simple durable mp3 player this is the one.100% recommended.
