The portable speaker provides eight hours of battery life (the charging time is about 4 hours) a thoroughly mobile use possibility. Battery performance I could not test and confirm so far, as the unit has found an elegant space on my desk and was always loaded the same. The processing of the Grundig GSB 500 makes a very excellent impression, similar one is used by the competing firm BOSE.
The maximum power and maximum volume related leaves nothing to be desired. The sound is great and without distortion at high volumes. The speaker makes a lot of pressure and produces tactile bass, which I was personally very important and I had to decide 500 in my buying decision between the Bose SoundLink Mini, the Bose SoundLink II and the Grundig GSB. The Grundig offered at increasingly higher volume, more and more oppressive basses that were in the competition also available though, but the highs and mids are slightly distorted. It is in this description to my personal assessment.
Ultimately, my choice fell on the Grundig Bluetooth Speaker, since it has a higher maximum volume, clearer and finer resolution mids and highs (compared to the SoundLink mini) and of course played the lower price also play a role in the purchasing decision.
I am fully satisfied with my decision and look forward to the upcoming garden parties, barbecues and similar events in which I can take my Grundig Box. Through the voluminous sound and clear highs and mids the musical enjoyment really is no obstacle.
