The verdict

The Shure AONIC 40 trims some of the excess of the AONIC 50, which makes for a reasonably priced, great-sounding pair of Bluetooth headphones. Mediocre and ANC and durability concerns notwithstanding, this is definitely one to consider.

✓Liked: Bluetooth 5.0; SBC, AAC, aptX, and wired, USB-C audio passthrough, Good app, Comfortable

✕Could be better: Expensive, So-so ANC
