Summary: I forgot to mention this really bad things...
Review: It occasionally can't play a track properly and freezes. The only way to sort try it is to flick around tracks or even turn it on and off, which is a pain because...Depending on what CD it is playing it can take 20 seconds to turn on! Criminal really. My £15 walkman never did that.

Summary: Good Overall
Review: It's a great addition to any mp3 fanatic, not to mention the options this has and other mp3 players don't. If you have music with id tags in other languages, the iriver is great for viewing those info, since imp-350 and newer versions all have multi-language codecs. There are some other nifty stuff, like customizing your own intro screen...However, this model does make some loud noisy sounds when trying to start up, shut down, & spinning the cds. I heard the IMP-350 is a little better in that respect. And sometimes, it would play the wrong song (when I specifically said I want a song to be played). That doesn't happen often, however. Be aware, there are no earbud headphones included...it's those around-the-neck types. The internal batteries are great, but they only last 5 hours at the most, and less with each wear. But, it's pretty good in the trauma department; shaking it while playing a cd or dropping it doesn't do much damage...the silver casing makes marks virtually undetectable. Ah...every good product comes with some flaws, what can I say? Nothing is perfect.

Summary: WARNING FALSE ADVERTISING!
Review: My Imp 400 just arrived (I was the owner if the 350 before it broke) and after excitedly unwrapping the package I was shocked to find a pair of clunky generic "IRiver" wrap around headphones and NO SENHEISSER EAR BUDS. They practically advertise the ear buds more than the player and now they aren't including them? I feel so ripped off, I know the player is fantastic but I'm wrapping it up and sending it back simply due to the principle of the matter. Don't lie to the customer...

Summary: Perfect for the "spouse"
Review: My wife isn't interesting in ripping CDs, creating mixes, MP3s, etc. Her goal was a unit that would play her large CD collection and would accept the crazy disks that her crazy husband generates. Given that sort of anecdotal background: this is the perfect player. Interface is easy to use (passes the "spouse" test once again), music quality is good and it is very tolerant of shake, rattle and rolls. I only rate it as 4 out of 5 because I personally don't like the disk form factor. If that's your thing, though, this is the player for you.

Summary: EXCELENT RADIO!!!
Review: Once upon a time in my life I bought the big brother of iMP-400, iMP-550. But the radio was worthless!!! It was only possible to listen to the strongest radiostations, standing still and holding up the earphone cable. Tried it at the absolute center of Stockholm (the capital of Sweden), and could bearly hear anything. ...so I returned the player to the store and, with some hesitation, bought the iRiver SlimX 400 in stead. I became very positively surprised! The radio in iMP 400 is very good, I can use it almost anywhere, maybe not in the subway but rather far down the stairs to the subway. However, the batteries only last for 5-10 hours (but charging is easy), and putting the mp3 on takes about 45 seconds and a usual audio-cd takes about 20-30 seconds (iMP 550 had the same delays), but I can anyway strongly recommend SlimX 400.

Summary: Review of Iriver Imp 400 Slimx
Review: Pros:
Iriver has come out with another amazing cd player. The Imp 400 has great features such as a 8 minute ESP, a wide 4 line backlit LCD remote, and much more. The slim design and the cover is wonderful. The color options are nice also. It also comes with Sennheiser MX300 earphones, which are much better than stock earphones. The rechargable NiMH are an added bonus, no more buying expensive batteries. The discharge and the overcharge features are good also. Cons:
But the Imp 400 needs to work on the price. ... the price of the player is a bit expensive. For [a little] less you can get the Imp 350, It has the same features as the Imp 400 but the style is a bit worse. The weird rectangular battery shape is a downside. Not many stores in the USA sell these types of batteries. Summary:
You should buy the Imp 400 if you want the latest style and features and dont care how much it costs. But if u want more bang for the buck buy the imp 350

Summary: An excellent portable mp3/fm player
Review: This is a great portable cd/mp3/fm player. Overloaded with many features. I only use this in my car, so im not sure about the battery life. The iRiver website says the upgrade to ver 1.2 should increase the battery life by an hour. The package comes with a car adaptor setup which I was not aware of until I got it, which was very nice. Two rechargable batteries, an ac adaptor an external battery pack for AA's. Also comes with a handy pouch/carrying case. Headsets sound great not top of the line but very durable. The remote is very, very cool looking with the blue backlight. I always keep it lit. You cant operate the player without the remote. I hope iRiver comes out with a wireless, that would be sweet!
The firmware upgrade from the iRiver website works but got a bit tricky. Its not very well explained and I found by trial and error you have to unzip the .exe files to your HD then burn the .hex files to your blank CDR. Do not burn the .exe files to your CDR. Only one .hex file per CDR disk. The unit comes with version 1.00, You can't upgrade from ver 1.00 straight to 1.20 you have to upgrade in steps from 1.0 to 1.01 to 1.02 to 1.2. On some tries to install the firmware I got a "no disk" msg meaning the player is not reading the disk. Just retry a few times, the player will eventually catch on. When the upgrade is completed I did not loose any presets which was very nice. I had this in my car for a few months and never skipped once. The unit itself looks delicate, I dont believe this would be the unit to buy if you want to go jogging everyday. I would buy this for you car or as an attactment to a audio component you already own. The sound quality is outstanding. Has very nice equilizer adjustments and about 8 default equilizer presets. Has a multitude of other settings to keep you busy. Once you get used to the iRiver format it becomes simple to understand and navigate through. Compared to another portable mp3 player I used in my car before using this one, it does seem to take a bit longer to queue up music, even on a disk without folders. Its not a complaint just something I noticed. The FM stero works great and picks up all the stations in the Los Angelos area. 20 presets help make navigation very easy.
I highly recommend the iRiver-imp 400 (in red!) and gave it 5 stars!!!

Summary: Very disappointed
Review: This is a physically beautiful unit, which should win awards for design. You can't judge a book by its cover, though, and I find myself a very disappointed user of the iMP-400. First, the unit recognizes none of the mp3 CD-R's I recorded on my G4 Mac's SuperDrive (under MacOS 9.2), even those these are easily read by my Kenwood CD player in my car. Second, often, while playing an audio CD under non-jolting conditions, the player just stops and does nothing. I have to select another track on the CD to get it going again, and then select back to the track the player had originally stopped on. Third, the remote unit is very difficult to 1) see, because of the microscopic size of the characters on the LCD, and 2) operate, because it is almost impossible to not inadvertently push a button while clipping the remote onto or off of your clothing. On the positive side, the iMP-400's FM tuner is the only digital unit I have encountered that will tune to a frequency that ends in an even number (e.g., 90.2 megahertz). This is important for those who watch TV in health clubs that have wireless audio transmitters, which are usually tuned to even-numbered frequencies so as to not interfere with broadcast FM stations, which always have odd-numbered frequencies. The sound quality of the unit is very good, but to get it you have to spring for some nice occlusive ear buds (...). The headphones that come with the iMP-400 don't sound good at all. I found the manual to be very well illustrated, but the text is way too sketchy and obscure. To figure out how to do something simple, I have to read the page over several times. The battery charging function is very weird. Instead of just plugging in the unit to charge the battery, like every other device I have ever owned, you have to 1) turn on the unit, 2) push the Stop button to put it in charge mode, and 3) select whether you want to just charge the battery, or charge it after completely discharging it.
