I just got my SlimX tonight. Let me qualify my statements by first mentioning that this is the first portable MP3 or CD player that I have ever owned. I'm used to listening to music on either my Yamaha home theater system or on my computer with Cabridge 4 point speakers. Thus, I'm a bit biased, as I'm used to pretty good quality. This is also my first experience with earbud headphones, as I use pretty decent Koss when on my computer at times.
That said, here goes.
The Unit is very stylish and pretty compact. Definitely smaller than the Rio in thickness, and it seems a bit in height as well, but not that much on height.
The remote is mildly clunky, not terrible, but not perfect.
There are too many features to list.
But here's the rub. I find the music quality, even when playing an Audio CD, to be poor. It's the headphones. I get distoration and a tinny sound. I plugged my Koss headphones in, and they sound great. These earbuds are the weak link. Does anyone know of really good earbuds out there that have an antennae in them?
