Edifier Connect App + W820NB Plus
Edifier Connect App seemless connectivity, but limited to only 4 audio tuning functions. W820NB Plus - Great headphones just lacks low end. But Mids and Highs are great! Noise Cancelling is decent Wishlist: Edifier Connect App: Manual EQ Tuning. W820NB Plus - Improve Bass. Overall happy with the headphones.
