Crazy affordable prices in this audio day and age.
The CA01 is already up on the iBasso store with the CA02 soon to follow.
I could further wax lyrical and add more unnecessary details, but the above is all you need to know.
They are well built, have a clean unadulterated sound and function as intended.
They are also useful for anyone with a Sony dap with a 4.4mm jack port, and for those with 2.5mm balanced cables wanting to connect to the single ended 3.5mm port of their daps.
CA01 is a 2.5mm balanced to 3.5mm single ended adapter.
