This is my review of the MyMusix, since there is no review of it online and the site itself doesnt even show up in Google, I figured I would share my experiences with this DAP.

Break down of specsSizeAppropriately small. The entire device is about 1 1/2 SD cards tall and about 1 SD card wide. Its maybe a finger deep (lay your finger flat).
A penny is the size of the 5 way nav joystick, and that takes up most of the front of the player

WeightNiMH batteries are very light, so the player with batteries felt about as heavy as a miniDV cassette in my hand

File SupportI pretty much use only mp3 and OGG so I dont know about the WMA. It does not support WMA DRM 10, only 9. You also must transfer DRM protected songs through WMP, not by drag-drop.

USB ConnectionFor USB 1.1, it was pretty fast, and as far as I understand, it even fares well with some USB 2.0 compliant devices. Id say I averaged about 3mbps max on the transfer. Not great, not horrible.

SNRThis player is pretty quiet. Even at the full volume of 15 its barely enough to block loud noise out (think slightly crowded restaurant). I use it to sleep with, so my most common setting is about 4-5. At full volume, there is no distortion. Thats probably due to how it doesnt get all that loud.

EqualizerThe equalizer settings are pretty bad. Normal is just straight sound (probably the best). Classical tends to muffle the trebel, Pop makes everything foggy, Rock actually makes deep bass sound nice and filtered but mutes treble/mids a little, and live really sharpens the mids and trebles but makes the bass almost non-existant. There is no user EQ option.

Play ModesAs listed. The random shuffle works pretty well, although it seems to take preference to some files. Time between songs (shuffle) on a card with about 1mb free was about a second. Tracks that are played sequential are nearly gapless, to the point that you wouldnt really notice at all.

DisplayI am extremely partial to negative displays, but I do have to say that this one irked me a little. When lit, its very sharp and pretty (blue back, white-blue text). If its not lit, there is absolutely no chance of seeing the display at all. NONE. Not even in daylight. My advice is to keep backlight on always, that way the display is readable in light. Otherwise, nice display.

BatteryI found that nearly all of these specs are as they say, except maybe the battery life. I used NiMH rechargeable batteries and the net time of over 12 hours was definately not achieved. Under normal listening conditions, I averaged about 8-9 hours per charge. Thats not horrible, but its pretty shabby for a card based player, especially since SD cards dont draw that much electricity. If you get this, use rechargeable batteries, else you will run through the devices' cost worth of batteries in about a month.

PackagingThe package is a plastic container (not blister) held together by one staple at the top. Easy to open, easy to reseal. The manual is sandwiched between the front display and rear display sheets. The player and SD card rest firmly in a molded plastic case.

Contents• 1 player
• 1 1gb SD Card
• 1 earbud type headphones
• 1 silver lanyard
• 1 proprietary USB 1.1 cable (dont lose this baby :C )
• 1 paper manual

ManualExactly what is available online, meaning not too great, not too bad. You dont even need to read it. Just pop in the SD card, a battery, and you are good to go.

PlayerThe player is very small, very light, and very nice looking. Its front is a shiny black plastic (marks VERY easiily, I cut palm pilot screen protector to cover it). The rear and sides are a shinyish silver plastic. Aside from the unit being only plastic, its very tight and feels solid in your hand. There are no really significant gaps though the backlight shines through the edges at night (see gallery). The 5 way joystick is easy to use and actually comfortable. My hands are pretty big and it works fine. It clicks easily and registers always. It does not ramp up speed when scrolling though.

ScreenAs I said before, its nice, but useless if the backlight is off. Its covered by the hard plastic, so its safe from physical shock damage, but will scratch or get smudged easily. Best to keep a soft cloth around.
The player displays the name of the track (from ID3 or filename), current time, total time, repeat modes and battery, A-b shuffle, and a signal graph (L and R levels). It actually refreshes very fast, so its kinda cool to watch. Useless, but cool for a geek like me

PortsAll that is on the player is the standard 3.5mm jack, a hole for the lanyard (Upper right edge), a hole for the reset, and a slot for SD card and USB port. The card sticks out a very little, but you need that so you can pop it out.

CablesWARNING - The USB connector plugs into the player upside down as easily as it does the right way. If you mistakenly plug it upside down, your computer will power off instantly. Or atleast mine did. No harm comes to either the device or the computer, though you will have to take out the SD card an put it back in for the player to connect properly and for Windows to recognize it.

File SystemThe player will read the SD card if it is formatted as either FAT16 or FAT32. I tried NTFS but it will not read from the card. FAT16 will provide you the best performance and least space lost (FAT itself takes about 8kb in FAT16, about 32kb in FAT32 and 8.3mb in NTFS). FAT32 will be a mite bit slower, but will allow for better error recovery and defrag abilities.

Playback performanceOn sequential tracks, its nearly gapless. On shuffle, it takes about less than a second (say "one" normal speed). When it changes tracks you hear the SD card access (slight static sound, only noticeable in absolute quiet and 15vol)

Audio PerformanceThe built in EQs were discussed, and are pretty lame. The player itselft adds no noise at all except when changing tracks.

Firmware UpdatesThere are 2 firmware updates for the player. The first fixes some display issues, and the second allows for folder navigation. The first must be installed and upgraded before the second one can be run. To update, put the .bin file in the root of the SD card. Disconnect the player, power on, go to upgrade, and select the firmware. It will restart shortly, and viola, done.
Note - I emailed the company, and they will be releasing a new firmware soon.

Menu NavigationThe menus are pretty simple, at most having 3 levels of depth. There is Folder (only when stopped), eq, repeat, lyric, contrast, power off, backlight, upgrade, version. Each is simple and very intuiative.

Music SortingThe device does not support ID3 browsing, only folder structure. Beyond that, it does not even alphabetize. I am almost 100% positive it sorts by date modified. So if you want alpha order, copy it over in alpha order :C

ControlThere exists only the 5way joystick, the menu/AB/power button, and the hold slider. The slider slides smoothly and stays put. The menu/ab/power button sounds hollow, but is very strong and registers well. The 5way is smooth and easy to push. The click is easy to hit, and ive only had to retry my click like once or twice. It works either left or right handed (i am righty) but I prefer to use it lefty.

Final WordI have used a Rio Karma, Ipod gen 3and 4, ipod mini, ipod shuffle, iriver i320 or whatever, Samsung YH-820c, YH-925gs, RCA RD2765, Rio Carbon, Rio Nitrus, Rio Ce, Creative Zen Touch, Creative Zen Xtra and mrobe 100. I have only owned one: MyMusix PD-205. From what I have experienced from the other players, its audio is fine. What really takes away from it is how there is no user EQ, no saving of settings, and no real browsing ability. If MyMusix releases a new firmware, all of that would be fixed, and it would be a great deal for 80$. I have written them, and they assure me they will release a fix for all of that, eventually. I cant wait for eventually. I returned it and will save my money for something better (i am waiting for the xs200 to come down in price). But like I said for 80$ its a great buy, and it would be near perfect if they fixed the software issues.

RecommendIf you just want a straight music player, dont care about browsing and such, then yeah, this is a great player. If that kind of stuff bothers you (EQ, ID3, settings), I would wait to see if they fix the firmware. If they do fix all the software issues, I would absolutely buy it again. Its 1gb, small, and I could care less if I wrecked/lost it for that price. But as I said, it has its issues. If you read the review, and it sounds okay, go for it. Radioshack has a 30day return with receipt and packaging.

Rating67 due to horrible firmware. If the firmware was fixed, I would give it an 85 because its near perfect, except for the invisible screen in light, and how its a little on the quiet side.
