Odin is a beautiful sound like starlight based on extreme resolution. I've used a lot of earphones, but it's so complete that I bought it three times.
Everyone that's owned DAPs knows they can sound great but good lord they're soooo slow. This thing runs like a $3,000 DAP. As fast as as a modern cell phone. Sounds great. Class A is great. Not the most holographic sound but really sounds quite good. At the price it's pretty fantastic.

The Shanling M3 Ultra sounds great, has a fast processor and runs on Android 10, which offers a lot of versatility. It has Bluetooth 5.0, a large bright display which is easy to read and a micro sd slot to expand internal storage up to 1 TB (it will be 2TB once the cards are manufactured).
I'd like to thank Andrew from MusicTeck for answering all of my questions. He helped me pick out this unit and I am very happy with it. He and his wife Grace are very knowledgeable and willing to help.
This is by far the most incredible IEM I've ever owned. The detail, separation and sound stage are incredible. I wish I had more time to listen! My only call-out is that the size of the tubes are fairly large--too big for me to use foam tips comfortably but small silicon tips would great. If you gave small ear canals try before you buy!
