This is the best Portable Stereo CD I have ever had. Not only it has dual voltage for worldwide used, it has 4 types of sound quality:
1. Heavy: adds punch to rock 2. Clear: clarifies higher sounds 3. Soft: for background music 4. Vocal: adds gloss to vocal
In addition to all those above, you can also create a three-dimensional sound field when listening to stereo sound. This additional feature is operated only by remote control which is included with this portable CD. It is light-weighted too.
