Reed Warbler - Panjin, Liaoning, China (1 Viewer)

Don't know if we can manage this one, but I had only the briefest of glimpses of any of the four Reed Warblers I heard singing today. Buried in the reeds to where I know I was almost on top of them and still not able to see anything. Audio attached if anyone can discern which one of the Acrocephalus they were.
I am between Oriental and Black-browed.

Oriental Reed Warbler.

Black-browed Reed for comparison....notice differences in tempo and tone.
