In our house even Apple iPod nano and iPod touch are available,
so I can compare the products very well.
The Sony NWZ 638 FB came in a small package, various adjustments
for the headset, USB cable (unfortunately Sony own), headphones and thin brief instructions.
First of all, I have the player on a Artwizz Power supply 3 hours
loaded until it was full.
Player switched on and marveled at the quality of the display. Individual
Pixels you can not see really. Razor sharp.
For movies, it is, however, turned out very small. Great for clips.
The player has 8 videos are pre-installed, as well as about 10 songs.
The video you can easily change to landscape.
Automatic is the only the Ipod Touch.
But now to the essential:
I'm not a Hifi specialist and can only my subjective impression
Play: class. Better than the iPod. Powerful bass and crystal clear highs.
By ear headphones outside noise very well shielded.
Another highlight is the FM Radio. I also have one in my Nokia
Handy, but against the Sony receiver part is irrelevant.
Really brilliant. No noise, no interference.
And do not be fooled by the pictures on Amazon, the device is just as
Great as an iPod Nano 2nd Generation. So quite small.
But fits comfortably in your hand.
The only thing that annoys me, Sony is specific USB cable.
If you do not have this, no shop or a transfer is possible.
Otherwise, I can only recommend the player.
It does not always have IPod.
Update:
Now I have tested the player under Linux (Gentoo).
Infected, recognized, transfer songs. Works perfectly.
Since I bought the player also order short
Play videos, including videos in FLV format,
I've been using ffmpeg conversion to MP4 format (H264 codec)
tested.
What can I say .. the player plays it.;)
No stuttering.
And one is also struck me:
On Windows, the transmission of the data takes to the player
significantly longer than on Linux.
I tested the Sony Transfer software under Windows.
You can rip CDs with the software and push directly to the player.
Unlike the Windows Media Player program found the Sony CD
directly from the Gracenote database.
Conclusion: A great piece of technology.
