The ATH-CKX9 SonicFuel earbuds are the top of the line in Audio-Technica's SonicFuel series for active individuals. Music fuels your lifestyle, and you need the finest available headphones that will also keep up with your activities. The stay-in-place fit gives users comfort, as well as optimized sound. It accomplishes this fit with a combination of sealing silicone eartips, and the flexible C-tip mechanism. The 360 degree rotating eartip will adjust to the shape of your ear, personalizing the fit for everyone. It also features a flat audio cable for easy storage without tangles, prolonging the life of your earbuds.
What sets the CKX9 from the lower two models is the large 13.5mm performance enhanced drivers. With the larger drivers, a premium listening experience is offered. The frequency range is expanded further, and sensitivity raised to give you warmer, fuller audio.
