Nothing above average but serviceable

Negative dropped me here on a lot.

- The manual is more bad than good. Sufficient for people who like to try around a bit, but on technical details such as battery life, charging time, option descriptions, etc. has been spared here strongly. Also online is nothing to get.

- The MP4 player should be at least the first time, stay tuned for people with poor language skills in English. The German translations, especially repeat options are extremely poorly translated. In English, however, the function will be quickly realized.

- Operating time without power saving mode (not abgeschaltetes display and full volume), the MP4 player as a runtime of 120 minutes (MP3), and the MP3 player about 200min. With switched off display and less volume also much more. The MP3 player I came to about 6 hours of running time with some breaks and moderate volume

- The battery level is not really seen. When MP4 player you can see him while using the icons could be from when the battery is fully charged, but the MP3 player only a reddish LED inside the housing, however, blinks when the unit is turned on, or connected to a USB cable flashes is. The flashing frequency remains the same until the device switches off completely. When MP3 player therefore it is not clear when the battery is fully charged or when it is empty.
Too low charge level makes the MP3 player first noticeable reference to the volume decreases slightly. Even the already poor sound of the original enclosed headphones is even worse here.

- The transmission speeds for the same data, as well as SD card, differ greatly between MP3 and MP4 players.
While the MP4 player with me between 10-12 MB / sec data transfers. Are there in MP3 player just times 2-2.5 MB / sec.
Uploading of data using card readers would be possibly useful

- The menu of MP4 player is used to, but manageable.

- The radio of the MP4 player is ok, here there are lots of station presets. Unfortunately, I at least I have not figured out how to save also can select this preset stations again. By means of the keys can only change in frequency in 0.1MHz steps, or a direct channel search. RDS is also not supported.

- Both players have when selecting tracks their quirks. Likewise, the repeat mode. The directory structure is very simple. Everything is available as MP3, is also detected whether the root, or in subfolders, and will play Alphabet. Here is the exist of multiple folders, and bookmarked setting Shuffle and Co, only the current folder for this function. Shuffle therefore affects only the current folder that is currently selected. The MP3 player does not have these options. He only plays Alphabet what just yet. A playlist by cumbersome renamed folders or files is therefore necessary.

- The sound of two devices is in between just as fine. This is, however, for the most part to the original headphones. In my other headset the sound is much better, but still far from good. Also the equalizer of the MP4 player does not have much of here.

- The keys are more cheap than good, but they do their job as they should.

- What is also noticed when MP3 players negatively. During the six hours 3 Songs beginning were poorly reproduced. Sounded like a broken record sooner or defective CD to, but must be on the device, since the MP3 will play properly again with renewed selection.

Well the positive things.

- Indicated is the product of up to 16 GB.
For me, both devices also have no problems with 32GB.

- When turning off remembers the unit at least over short period of time the title, where the player is turned off.

- The accessory is sufficient with 2 headphones, 2 power supplies and 2 cloth bag. A pen for touch pads has been likewise with me.

- The dimensions of the MP3 players are really less than tiny. Through the clip, which holds even surprisingly good, is the small part anywhere

My conclusion, therefore, ... 40 euros is a bit exaggerated for the two devices in my opinion, but the MP3 player for jogging and Co is really well suited. But I think there is less money for better equipment now. Whether this is due to built-in Bluetooth. A better directory structure and track selection, or by the sound quality.
