I recently bought the dongle from Meizu for about USD25. I compared it to MU2 plus and Apple dongle so I'm not sure how is it compared to MU2S.
I found that it's quite competitive for its price.

Good:
- Supports microphone input
- Compact size
- Works with Onkyo HF player exclusive mode
- Sounds better than Apple dongle
- Low output level (lower than Apple dongle, enough to drive HD650 on Windows but not Android)
- Max output levels on Android and Windows are different (same as Apple dongle)
- The steps of volume control on Android are too big
- A small pops in the first minute
