Summary: I HAD THE SAME PROBLEM!
Review: I AM NOW ON MY SECOND RIO600 IN JUST 3 MONTHS - AFTER BEING CHARGED $30 TO HAVE THE FIRST ONE REPLACED BECAUSE THE SOUND WENT OUT ON ME. WELL, THE SAME THING HAS HAPPENED TO THE SECOND ONE. THIS IS RIDICULOUS - ESPECIALLY WHEN TECHNICAL SUPPORT CAN DO NOTHING TO HELP ME. I WOULD DEFINITELY FIND ANOTHER PLAYER - THIS IS A WASTE OF MONEY.

Summary: Would Be Great If It Worked
Review: I'm now on my 3rd unit. The first was a raincheck substitution at Best Buy (amazing isn't it). That one skipped and distorted all of the songs that I put on it. Then it finally ceased to work at all. It played back popping and static. The second unit was playing fine and then suddenly started to pop and play static like the other unit did. I tried everything to get it to work but no luck. I updated the firmware and the Rio Audio Manager Software and that ended up being a waste of time. I'm crossing my fingers on the third one. A note of advice: Don't shop at best buy I you intend to return something. They have even worse service than Diamond/S3/SonicBlue and the morons back in computers have no idea what they're talking about. If you want an MP3 player, go for the Compaq, or the Creative Nomad. Diamond went from a company that makes quality players to an enormous superpower that can't get anything done.

Summary: Best yet
Review: The Rio 600 is the best mp3 player I've yet to see. The music quality is great and thats just the beginning. The design of the 600 is better than any other. Smaller than a cassette and puts out louder sound than my cd player, trust me you'll be amazed at just how loud it really is. The sleek design is great with changing face plates make it even better. Cons? Maybe that it comes with a cheap neoprene belt-clip/case. I also use the headphones from my cd player because the included ear buds can get uncomfortable. But still the best over all player I've seen. It's my recomendation to anyone. For those of you debating between this and another... you have to go with this, you definetely won't regret it. It only comes with 32mb of memory but for the 300+ that will be available it will be a while before it becomes obselete.

Summary: Rio 600-Not a bad bang for the buck.
Review: Compared to most other things on the market, this isn't a bad buy for an MP3 player. Why? -Ability to easily update player ROM to support future music standards. -Fast USB connection. -Expandable storage medium using the backpack 32mb module. -Decent playlist manipulation. -You can use other programs (i.e. Windows Media Player) to download music to the player. -Lightweight design.What isn't so great: -The software that ships with the product is insufficient at best. Use Windows Media Player or (eventually) RealJukebox to transfer (someone please complain to Diamond). -Toggle design lacks a cohesive and ergonomic design. Curve doesn't improve grip, toggle can be difficult with only one finger. -More advanced customization would be helpful. Overall, compared with similarly priced models in its range, the Rio 600 does perform well and deliver.

Summary: Good product, great customer service
Review: For the price, it would be hard to beat this player. I got it as a present for a 12-year-old; I didn't want to spend alot of money on an item I would find under a pile of toys in 6 months (as has happened with gameboys, etc.) The software is a bit cumbersome, but their customer service reps were great and solved all my problems quickly. Since it's expandable and upgradeable, I have no problem with the small amount of MP3 music it holds. Also, it is a very cool-looking item, unlike most of the gross, overly chromed consumer electronics things you can buy. I think I might buy one for myself!

Summary: Pretty Nice
Review: Okay, I just received the 600 for Christmas, so I feel like I should review it for anyone else thinking about getting it. I have read most of the reviews so far, but my complaints are somewhat different: Minuses 1. The headphones - they sound good, look pretty cool, and are extremely convenient in terms of size. People, they hurt, literally. The ergonomics of these things are baffling. After wearing them for only 5 minutes my ears are honestly IN PAIN. I love the style, but can't someone come up with a better design? 2. The 4-way control button is one of the more frustrating devices I have come across in recent times. If you dont press down on the exact spot to fast forward/rewind, you will end up hitting pause or stop. Again, do people actually test their own designs? It looks hip, but the control is tedious to work. 3. Memory. Come on guys, who releases a brand new MP3 player in late 2000 that only has 32MB? Why doesn't Intel re-release the 486 chip while we're at it. I get a lot of music from Napster, and I consider 128kbps the lowest acceptable rate. At that rate, the average song is about 4MB...that's about 8 songs at once on the device...very weak. Sadly, the memory backpacks that are soon to be released (only 32MB for now, though they claim up to 340MB on the box) are about 90$.You'd be better getting the 800 instead if you do the math. 4. The software isn't all that. I'm going to use RealJukebox instead of the provided software I think. Pluses 1. Lightweight 2. Surprisingly long battery life. It only uses one AA battery at a time too. 3. Loud! I havent even gone up to the loudest setting. 4. Nice belt clip included (which oddly, the Amazon review says it does not come with). Very well made. 5. Good sound overall. Anyway, if it were up to me, I would have gotten the 800, that might be the best MP3 player out there now, but I would have to try the control button first. The 600 is very nice though. It will hold a long CD if you rip it in WMA format by the way.

Summary: Man this is total GARBAGE
Review: When purchasing an mp3 player there are many things to think about, such as, price, size, memory, sound, etc. When i asked my parents for an mp3 player for Christmas i expected a high quality futuristic piece of machinery. Diamond should really make a recall on this product - scratch that they should never have released it. When i opened it i knew it would have problems, i have a spider like sense. Anyway, the DIAMOND RIO 600, iss garbage, its ugly, the software has constant errors, the usb cable/mp3 transmitter is total crap, again error messages are constant, so i was never able to rip a song onto the rio 600. However, the sound is quite nice, but thats if you want to listen to the intro and some nasty songs over and over again, because you'll never get the transmitting process to take place. Overall its a 1, because it practically ruined my Christmas and its a P.O.S if you will, in fact, im taking it back tommorow. My suggestion: DONT BUY IT!

Summary: A great mp3 player at a great price
Review: I just recieved my rio 600, and is everything I hoped for and more. The sound quality is wonderful, and the ear phones are really cool. I heard some bad things about this one, so I was a little nervous about buying it. I don't understand why anyone wouldn't love this one. I can't give it five stars because, I had some trouble downloading the music onto the player at first, and it doesn't hold that much music. But, I still recommend it.

Summary: Poor design. Too big, Too Loose, Too bad...
Review: I've owned the Rio 500 and I liked it. If you MUST own a RIO get a 500 atleast you can use smart media cards. Its bad enough that the 600 uses a RIO only method for expanding storage, but the design of such is bad. They had to put a weird plastic peice of junk around the battery. The pins are very easily bent or broken when reloading batteries or upgrading the back panel. The device is physically larger than it should be, and it is made of the WORST plastic possible. A soft compound that would not be durable. OVERALL BAD PRODUCT. PLEASE SHOP AROUND. AND CHECK OUT REVIEWS. DIAMOND gets what they deserve for letting this peice of junk make it all the way to market.

Summary: LASTED ABOUT A WEEK!
Review: I wish I had waited and read the reviews earlier as I too, would NOT have purchased this item. It's a roll of the dice from what I've read. You might wind up with a Rio 600 that functions for you at the level expected. Or you might not. It may last a few days, or as in my case a bit over one week! The sound quality went from really great to TOTALLY UNACCEPTABLE! The Joy pad does not function well at all. Sometimes not taking input at all, sometimes responding with wrong results. I would consider this item's quality control to be non-existant.
