Lately – as days grew longer – I thought it was time to start a new project, Aero One. The keyword stands for a new portable audio system similar to The Bee, but smaller and lightweight. The weight and the dimensions of The Bee did not allow to carry it on a summer day to a park. A side effect, when not using The Bee was, that 15€ mini speakers came into action frequently. Indeed, they are better than raw smartphone sound, but compared to any loudspeaker with at least a small ambition for high fidelity sound… that’s not comparable. More expensive mobile products have not been an alternative for me, because 1) I rather like to build such stuff on my own and 2) I don’t like hyped music pills, where most of the price is due to the brand.
