Noble Audio FoKus Apollo review: The high price of pristine audio

That's because most audio companies sell their top-of-the-line gear around 300- 400. The FoKus Rex5 earbuds, for example, cram in five separate drivers where much of the competition uses two at the most. Noble was also among the first to employ xMEMS drivers in wireless earbuds in a bid to improve bass performance. Enter the FoKus Apollo, a 649 pair of active noise canceling (ANC) headphones with a detachable boom mic and up to 80 hours of battery life. The real star of the show is the driver setup, which Noble says is the first time this configuration appears in wireless headphones.
