“Nura’s first headphones were certainly a conversation starter. The hybrid design mixed over-ear design, with in-ear buds. The wireless headset’s main trick, however, was the built-in audio test that uses otoacoustic emissions to spot any weak spots in your hearing and adjust the sound to compensate — like having glasses for your ears.
Nura’s just revealed its second pair of headphones, called the NuraLoop — the design is much more conventional, similar to many sports-flavored wireless buds. But that all-important hearing test remains.”
