The U4-SE is a Special Edition version of the popular 64 Audio U4 model. Designed for discerning listeners who crave detail and clarity but don’t want to sacrifice the presence of an impactful low end. In this model, 64 Audio placed the patent-pending apex module even closer to the speakers to relieve air pressure before it enters the ear canal. This makes for a wider sound signature, with a leaner bass that allows the mids to be more transparent and still provides incredible balance throughout all frequencies.
