We would like to thank Alejandro of myirock for sending us the irock 830 MP3 Player for review.
The irock 830 comes equipped with 128 megs of memory; which is good for about four hours of music. The unit is also both MP3 and WMA compliant. On top of digital music the unit has a built in FM radio with 20 configurable presets.
Included with the unit was, a pair of earphones, neck strap, case, 1 AAA battery, USB cable, and a CD with programs used to transfer mp3s to your unit.
An LCD display on the front of the unit lets you scroll through song selections as well as other modes.
To tweak your music an equalizer with 5 presets including: Flat, Rock, Pop, Jazz, Classical is also available to suit your taste.
One nice feature about this MP3 player is it can read ID3 tags, so you can read what the song names are.
A jog wheel similar to the 530 series, volume controls and equalizer buttons are used to control the unit.
Battery costs to run the unit are low and the irock needs only one triple A battery to run, which gives you about 30 hours of continuous music.
