Anyone has this mp3 player? How's the battery life with regular cd audio?
What finally got my attention was BestBuy was selling it for $120 even though on the internet it sells for $150. Even the original Mojo was priced much higher. I thought it was a mistake and I wanted to capitalize on it.
After much fighting with my inner-self, I decided to get the TDK Mojo 620 yesterday. To my surprise, there's a $20 mail-in rebate as well, making it an even better deal.
I was also looking hard at the Sony D-CJ506CK player. Sony claimed 24 hours for mp3, but then again they might not have taken into account if ESP is enabled.
I will be posting my review soon. I'm putting this player to the test. Given the player went of sale this April, there hasn't been any firmware updates. I've already noticed minor skips and glitches. In two instances, already, I've had track cross-overs, where one song is playing and then all of a sudden it jumps to the middle of another song I previously played. I'm guessing there's illegal memory location jumping going on. Hopefully this can be fixed with a firmware. More to come later....
But is ESP needed for MP3s? Don't they just fit into memory as whole?
With the Mojo 620, TDK claims that it can buffer 8 minutes worth of mp3, about 2 songs. I believe Sony's has 2 levels of ESP. I guess, the bigger the buffer the more juice the device sucks.
As I had previously mentioned, it was either Sony or TDK. I spent about an hour in the store just staring at both players and meticulously dissecting every inch of their design, within the limits of their sealed plastic packagings. If I had the money I would’ve gotten both.
Hands down for Sony’s D-CJ506CK, which was more esthetically attractive than the TDK Mojo 620. Sony’s has been around for years and they certainly know how to design a product. Their latest CD-MP3 player is an example to their ingenious designs. The player looked sturdy and yet elegant with its modern look while the TDK’s Mojo 620 looked like any other budget CD player with the clam-shell look. Although, this is a marked improvement over their previous model which was all black.
When you open the players’ lid you’ll notice that it is held only by plastic hinge-like thingies and a bent aluminum that acts as a spring. When I saw this I quickly wished I had a Sony. Given the force I had to apply to lock the lid open when changing disks, I fear that these plastic hinges will break off prematurely due to the torque needed to lock the lid open.
The bait that finally set the hook for me was TDK’s bigger, 4 line, dot matrix LCD, and previous success with the original Mojo. Sony on the other hand is a relatively newcomer in the field of CD-MP3 players. Besides, there was also a $20 rebate for the Mojo 620, which brings it $20 cheaper than Sony’s.
I’ve had four days now to test the Mojo 620. My first impression of the player isn’t all that great nor is it all that bad. With the top-money I’m paying for this player, I expected a better performance and what I got is a mixed-bag of raisins and chocolate. The first day I got it, I’ve experienced very minor hiccups when playing MP3s. I just want to emphasize that the skips would probably go unnoticed to most listeners if you weren’t looking for it in the first place. It’s a rare occasion(maybe 3 times since I bought it), so I can’t positively identify the cause of the hiccups, but my guess is that it happens when the laser buffers one MP3 file and on to the next. Browsing the menus while listening to music might also be a factor.
Another problem I’ve had is track crossover. I’ve already experienced this in two occasions: when I pause an MP3 song and resume it after awhile, it jumps to the middle of a previous song. My guess is there’s illegal memory location jumping going on. I’ve already contacted TDK about this and hopefully there will be a firmware upgrade if enough people report this glitch.
I’ve noticed that with lesser quality MP3 songs, there’s a slight click sound when changing to another track. Nothing major here, as it is preventable by using higher bit rate MP3s.
The player supposedly has 8 minutes of buffer for MP3s and 48 seconds for regular audio CDs. This feature can be turned off and some say this helps expand battery life. I haven’t tested this so I can’t attest to it. To tell you the truth, I can’t tell the difference whether I turn off ESP for MP3 playback or not. The performance is the same and if the theory is correct, just disable ESP for MP3 playback to prolong your battery’s short life. There really is no added benefit with it on. May be I’m wrong.
From my observations and mind-bending, mathematical calculations, the player buffers about 6 MB worth of data. This translates to about one and a half worth of 4 minutes, MP3 audios at 128 Kb/s in memory. The motor spins down once the buffer is filled, to conserve power. This is a very neat feature.
The unit comes with two AA Duracell Ultra, non-rechargeable batteries, which are rated 1500mAh. They’re supposed to last for 10 hours. That’s pathetic if you ask me. Regular AA batteries that I used during testing lasted way below the 10 hours. It was more like 6 hours. I guess my constant button clicking and the LCD light turning on all the time, further reduced battery life. I give one rotten egg to TDK for not engineering a much more power-efficient device. Sony claims a 24-hour continuous playback with their player. Ultimately, I suggest you go online and buy a handful of high-capacity, rechargeable NIMH, 1800mAh batteries. If you shop around you can find 2 AA rechargeables for less than $3, excluding shipping.
The player supports ID3 tags and TDK’s proprietary tagging called FIF(file in format). You can either set the player to ID3 or FIF to display song information. FIF really isn’t a tag like the ID3, where the information is imbedded in the MP3; instead it’s simply a naming format: <artist>-<file name>-<genre>.mp3 It’s really that simple, but imagine renaming hundreds of songs in that format. Hell No you say. I’m with you, but it’s the only way if all your songs are in a single directory and you want to browse by genre or artist; otherwise, you’ll have to put songs in genre/artist folders before burning to disk, then you can browse by directory. FIF is used for directory navigation whether you enable ID3 tags or FIF. The ID3 tags are used only for displaying song information if enabled and not for navigation, otherwise, the FIF formatting will be used to displaying song info.
The package comes with 3 softwares: LyricSync, Navitrack, and Logo Editor. LyricSync enables you to view lyrics of MP3 songs on the players LCD, Navitrack helps with the name formatting of your MP3 files to FIF, and Logo Editor let’s you change the logo displayed on the LCD of the player when it is turned on.
Other things included in the package are headphones, a wired remote control, and a DC adapter(a plus).
That’s all there is to it. The Mojo 620 is easy to navigate and its multi-functional buttons are quick to learn. I would definitely recommend this player to anyone. If you act now you can get it at BestBuy for $100.
I will update this review if anything changes.
