Summary: 2005-04-12 04:18:07 The iAudio 5 (firmware v1.10e)
The iAudio 5 is a very capable and full-featured flash-based portable audio player that includes an MP3 player (plus OGG, WMA, and WAV formats), an FM radio with presets, and both voice and line-in recorders, all in a 3" x 1-3/8" x 3/4" package that weighs less than two ounces including battery and protective case.
It has a well laid-out and comprehensive LCD that is larger than most: a 128x64 graphic LCD on the left that displays ID3 tag info and sound settings (MP3 mode), or radio station dial (FM radio mode) that blends seamlessly into an adjacent 4-line LCD on the right that shows the player's overall status (mode, volume, battery level, track time, and VU meter) at a glance. The entire display is illuminated by a customizable 1000-color backlight that allows you to specify the LCD colors for MP3, FM radio, record, menu, navigation, and song change modes. For example, you can set blue for MP3 mode, green for FM mode, red for record, etc. Very nice.
Transferring music files is a snap - the iAudio 5's FAT32 file system appears as a removeable drive under Windows and the USB 2.0 interface is quick - just a few seconds for a typical 128 kbps 4 MB MP3 song. Entire albums (~50 MB) averaged only 20 seconds to transfer. The 1 GB flash storage is spacious, too. I was able to squeeze 21 complete albums plus a handfull of singles onto it.
Sound quality is absolutely fantastic and, like most features on the iAudio 5, is fully customizable through a quite complete panel of adjustable audio settings that includes:
• User-adjustable 5-Band EQ
• BBE (makes music more vivid)
• Mach3Bass (reinforces super low frequencies)
• MP Enhance (compensates for lost parts of sound)
• 3D Surround (gives the sound a wide sense of space)
I found that the exact placement of the buds within the ear have a direct and noticeable effect on the sound, particularly the bass, so experiment a bit before feeling compelled to trade them in for something better.
Battery life is still under investigation. Cowon claims 20 hours, but the supplied alkaline AAA battery lasted only about eight hours. Of course, that included alot of LCD backlighing (adustable time-on from 0 to 30 seconds, or always on, BTW) as I learned to navigate the extensive but always intuitive menu system. I should point out that while connected to a PC, the iAudio 5 is powered by the USB port itself, so battery life is not an issue if using the iAudio 5 as a flash drive and playing songs on Windows Media Player. Still, I would highly recommend investing in a set of rechargeable NiMH batteries. The Energizer 850 mAH AAA I just purchased has been going for 12 hours and counting...
Some minor complaints:
1) The plastic body gives the iAudio 5 a somewhat less substantial feel compared to its metal-housed predecessor, the iAudio 4. Not that its cheap construction, mind you - just that an aluminum housing would have been more fitting for a player of this calibre.
2) The jogwheels are somewhat picky about being absolutely centered when being depressed. If not centered, they move only stubbornly and with a grinding feel.
3) The FM sensitivity could be stronger. Reception tends to drop in and out of stereo with regularity with only a few local stations locking on with good separation.
4) A more direct way to mute the audio during FM play is needed. FM mute is currently activated only by reducing the volume to zero - not a very quick or elegant solution.
I spent several months comparing feature sets, prices, and quality of current flash-based MP3 players (iRiver, xDrum, IOPS, MuVo - I tried 'em all) and for what it's worth, I found the iAudio 5 to be the best flash-based MP3 player of the bunch. The only other player that made it into the final elimination round was also a Cowon product, the iAudio U2. With a firmware update to add OGG format and a realtime date/time function, the U2 offers the same great feature set as the 5 in a slightly more diminuitive package, but in the end it was that cool 1000-color LCD that sold me on the iAudio 5.
