Dripp Audio is a new company that has put its interestingly-named true-wireless earbuds on Indiegogo. The "Dropps" are described as the cheapest products in their category to have Qualcomm aptX and cVc noise-cancelling tech. They also have Bluetooth 5.0 and IP5X ingress protection, and start at US$39.

Tronsmark Spunky Beats - about $27 during regular sales on Tronsmart Aliexpress store. Not sure how good they are (waiting on delivery), but also Qualcomm/Aptx/BT5, so these aren't the cheapest. Other Tronsmart products have given me good service so I'm optimistic.
Should have aptX Adaptive/Low Latency codec, then I'm ready to pay a higher price too.
