Caller says sound is fine. I was skeptical. super frustrating. We order from amazon a lot. I?m a size 4. The wire retractor works great and the ear buds stay in the unit for storage very well. They were still roomy. I am having to slowly break them in, first time Ive ever had to, but then, my feet are different now. So Wking, why not have the same outdoor Mode like the Wking D8 keeping the bass? I hope a software update will be available soon. Plenty of adjustability, simple tensioning system, doesn?t seem chintzy at all.
