Don't think the Ruizu has anywhere close to the sound quality of the Benjie. To my ears, the Ruizu sounds flat and 'closed in' in comparison.
The Ruizu has its uses though for a few reasons as an extra player to have around as:
1. It's amazingly inexpensive for the functionality you get, considering its a lot cheaper than even the Benjie. I mean £12 from gearbest for a player that is even vaguely listenable is amazing, never mind that it actually sounds ok, supports a 64gb card and displays the album art.
2. Really lightweight.
3. Battery lasts a zillion years before it runs out so no worries for travelling or even a festival or something. I've slept using it for multiple nights with no charges between, it's played all night and still not run out of battery!
4. In bed you don't want to end up with something metal touching you on a cold night, it is a nice reassuring warm plastic!
Just don't expect similar sound quality.
