Apple is only selling the large original HomePod now. It is being discontinued without replacement.
The HomePod was never really successful in its sales. For many hi-fi enthusiasts, it was simply too small to replace a real stereo system in the living room, and for users who were just looking for a small smart speaker, it was simply too expensive at several hundred euros. It was just somehow in between, so Apple has now stopped production.
However, Apple has a real bestseller in its lineup with the HomePod mini: small and round, with good sound, Siri support and thread support for the smart home, the small version is a purchase loved by many. Apple has thus succeeded well in transferring the most important features of the large model to a small one and thus also staying below the price of 100 Euros. So the HomePod is dead – long live the HomePod mini.
