3D Accelerated Gaming heeft een review van de Pontis (ken ik niet) SP503 MP3 player online gezet. Het spelertje wordt geleverd met slechts 16Mb flash memory, kun je net een kwartiertje muziek op kwijt raken:
OK, so we’ve been through the look, how does it sound? Sounds Great. In fact, I was perplexed (Is that good?--Ed) by the sound quality provided by the SP503. This player comes with very good earphones, in which with the whole ensemble, if you maxed the volume, everyone in the room can hear the sound clearly. I learned this, of course, during math class that day. I’m a biggie on equalizers and many barely do anything at all. The equalizer on the SP503 works fine, and the changes can actually be heard. Any drawbacks? Well I was listening to a couple of my favorite songs on the player during math class. THAT is the drawback. What? Well its very simple, I could only fit TWO songs on there. Of course they were high quality, each running at approx. 5 minutes each. But you still can’t fit many songs onto a 16 meg card. At the most I could fit about 5 songs. This was the GREATEST annoyance I experienced using the SP503.
