Can you tell us what iems you compared these to and how they contrasted? Thanks

Thank you for your question. Since I don’t own any IEMs anywhere near the price of the A8000, there was nothing to compare to. However, I did have an opportunity to listen to the 64 Audio tia Fourte for an extended time, so that is my reference in regards to upper tier IEMs.

Nice and good wrapped up review. How is the A8K vs. the B1?
