Onkyo is known for producing among the world’s best audio components for home theater and hi-fi listening. Now you can take that component-quality sound everywhere with a pair of our ES-FC300 On-Ear Headphones. Built to deliver maximum fidelity at a realistic price, these stylish aluminum-encased headphones feature 40 mm (1 9/16?) titanium drivers backed by sub-chambers to optimize bass response. Onkyo’s technical team spent countless hours tuning the drivers to deliver uncommonly clear, open, and natural sound from compressed or lossless formats. Premium audio doesn’t come at the expense of portability.
