The best choice for little money was for me so far always the Wavemaster Mobi. The Digitus is much more massive and affects the metal surface and high quality. It sounds at a similar level, but is much louder and sounds in the high range also much clearer than the Mobi. In the bass he goes considerably deeper, where you hardly hear the bass, but rather feel. The low frequencies are emphasized more clearly, however, if it is placed on a suitable surface. The tacky rubber surface at the bottom is intended to similarly similar to Wowee Tunebug and to be able to give vibrations to the base as with all the vibration or Gellautsprechern so that they can resonate as an additional tone generator especially below 100Hz. Depending on the situation, whether wooden table, wooden shelf, or glass table, the result vary widely. I have a chest of drawers in the hall, on the Digitus sounds like a really great speaker. That the bass on the way is not very precise, is clear. But the sound is so much more fun than without, and must take credit to the Digitus that he also quite passable sound by itself without any aid where the other vibration speaker without backing really only whisper. The Digitus manages actually to about 80Hz reproduce frequencies audible, including it's more just vibration.
For my taste, the Digitus is something to height emphasized. The fact that he gives not so much bass that height range simply is too dominant. Although the manufacturer's instructions so that brags that the speaker on a "real-time volume detection" dispose in order to optimize the sound even at low volumes, I noticed none of this. The speaker begins only at high volumes generate enough vibration energy so that really creates a certain "punch". At low volumes, it helps a lot if you have the opportunity, in addition to stress according to the low frequencies of the player by EQ. Excessively high volume levels of the speakers can begin to hop and chatter then despite the high weight, which then likely already sounds like a distortion. However, Pressing him tighter against the pad, you realize that he still reasonably clean play and just can not adhere strongly enough to the surface. A pity, I find that to date not a single manufacturer has reflected on its own suction mechanism so that the speakers actually will adhere correctly.
Only near the maximum volume and bass-heavy music, the sound is dirty, but this level is already a lot louder than most other mini speakers that I know, including Jambox etc.
With the right preparation, it creates quite a Digitus 10 times as expensive Jambox sound to defy. There's a lot of fun with the right site rumzuexperimentieren and you often hard to believe that the music actually comes from this little jar. It sounds so much better than most already many times more expensive vibration speaker, which is why I can recommend the Digitus completely.
