Be it a busy street, a crowded commuter train, or just everyday noise, there are plenty of times we'd like to have an EQ for the sounds around us. And that's just what the Here Active Listening System provides. This pair of wireless in-ear buds works in conjunction with a built-in DSP and a companion app to give you control over real world sounds. Active noise cancellation can drown out unwanted sounds, the equalizer can transform live music, sound effects and filters let you experiment, and preset modes make it easy to manage common situations. The buds offer a battery life of six hours, and include a case that doubles as a charger.
