Looking for a Blutooth Speaker, there is a large Auwahl in every price range. The usual suspects of JBL, Logitech, Raikko, Bose, etc. can be found easily. I always wanted to love the Bose SoundLink mini, but ultimately it was me but too expensive. This Grundig Speaker emerged only after a long search. After seeing a review of it on youtube and the Speaker significantly dropped in price, I slammed. I was not disappointed, look and sound, I find in the price range really very good. In controlling the blue LED is in my eyes but a design error. Is on the Speaker, but not connected by BT, the LED flashes continuously. This is quite annoying and even nonsensical. I know other solutions that are intelligent, there you have to establish a BT connection by turning a few minutes, then it is no longer and the light stops flashing. Will you then enable BT simply again and switch. Is the speaker connected by cable has there not the problem that it is flashing constantly. When GSB 120 the LED blinks continuously even if one already for 2 hours by listening to music or cable transmits the sound for a film. The product is well otherwise, the error annoying, but with an adhesive strip to solve halfway, but not beautiful. What I miss is the ability to connect a headset in addition. This option is, however, almost none of the current BT Speaker, so it is also not adversely noted.
