The iRiver iHP-140 is the ultimate digital audio player. Archive over 1200 hours of your favorite music, or tune in to the built-in FM radio.

The iRiver supports the most popular music files MP3, WMA, ASF, WAV and OGG. In fact the iRiver also is capable of real time MP3 encoding this means you can copy music onto the iRiver without the need of a pc, the iRiver ihp-140 converts your song into mp3 format by itself.

One benefit the iRiver ihp-140 has is the ability to upgrade the device when future formats and features are developed, this means the iRiver ihp-140 is almost future proof as well as this the ihp-120 is more than just an mp3 player as it also features an fm radio and voice recorder. Another handy feature lets your store any type of file on the player for transfer to say another PC via its USB 2.o interface. The USB 2.0 interface is up to 40 times faster than USB 1.0 and for people with older PCs the ihp-120 is compatible with USB 1 although slower transfer speeds will be observed with a USB 1 connection.

One drawback of the ihp-140 is that battery within the iHP cannot be replaced as it contains an internal battery that cannot be removed. The life expectancy of rechargeable batteries is usually calculated by how many times it can be re-charged / discharged and charged. The manufacturer of the iHP battery guarantees that it can be re/discharged over 3,000 times. It is also guaranteed to perform at a minimum of 80% of its initial performance before 3000 times of re/discharging.

Considering these factors, if you play the iHP for 4 hours per day, you can play it for 4 days before recharging it considering a fully charged battery can last up to 16 hours.

After 3 years of use the battery performance will still perform at least 80% of the initial performance. The initial playback time may be shortened to 12 hours and 48 min (from initial 16 hours); therefore the battery expectancy life will be about 4 to 5 years for normal users.
