Everyone hears differently. To account for this, Nocs' new NS1100 Air earphones have Audiodo personalization technology built in. Using an app, users go through a three-minute calibration process that optimizes the sound quality to their unique hearing signature. The buds use custom-made 9.2 mm Graphene drivers and hybrid active noise cancellation to deliver detailed audio, with a transparency mode available when needed. They also have four built-in MEMS mics for calls and noise cancellation, and offer nine hours of battery life, with a total of 30 hours available when using the included charging case.
