Although the website mentions that the stock is 'coming soon...', I am still waiting from 3 months. Newer variants (Atomik BB35 etc.) are nowhere near this in terms of bass effect. Please bring it back... Or develop new boombox with similar sound quality.🥺
I don't know why Blaupunkt pulled back this product from the market. Company should bring back this product as soon as possible along with the wireless microphone.
Very good quality sound and robust construction with excellent battery backup. bass at higher volume is excellent and is almost nil at lower volume . Overall very satisfying product
One of the best portable speakers in the market. The company should re-stock and manufacture it.

Blue Dot of Perfection.
A company named “Ideal” was first founded in Berlin when radio was still in its infancy. Every unit was carefully tested by technicians and labeled with a seal for quality – the blue dot. It did not take long before customers simply asked for the “bluepoint” (which means in German BLAUPUNKT) products. The blue dot quickly became a symbol of outstanding quality.
