Before receiving the Fantasy Pro Z1 LED Lamp we were a little bit skeptic on the overall sound quality because we did have previous experience with the Razer Ferox quite some time ago and while these sounded good on high frequencies, the bass was pretty non-existent. The small speaker seems to do wonders with this model because it can deliver clear highs combined with bass at decent volume levels; we have often turned the volume to maximum levels while paired with our Meizu MX4 and on several tracks we did not spot any distortions. The software seems to bring a decent level of customization to the product by adding light effects but it does not reside for now in Play Store and we need to download it from the website after scanning a barcode from the manual.
