3DHardware.net heeft een review van de Kaser Corporation YO!MP3 portable MP3 player gepost. De Jomp (hmm, kazig naampje... ) heeft 32Mb geheugen en is met 99 dollar erg redelijk geprijst:
Shockproof and memory size in all honour, but what good is a funky portable audio system without good performance? Nothing. Well, luckily enough the YO!MP3 is really good in that area. As I described in the intro, and you?ve surely experienced yourself, the MP3 audio format delivers really good sound quality at 128kbps (standard bit rate). As the sound quality at this bit rate was close to perfect (from what I could hear using my favourite Sony MDR-V200 headphones), I don?t recommend using higher bit rates (which I did, without any relevant change in sound quality), because this would only be a waste of valuable memory.
