Audio-Technica's Solid Bass technology utilizes the company's newly developed Double Air Chamber System. In addition to the main air chamber that houses the driver, the earpieces have an additional chamber that operates in conjunction with a specially shaped housing to control and focus the air flow produced by the driver movement and expand its bass output.

The earpads on the ATH-WS70 and ATH-WS55 over-ear headphones further enhance bass response by providing an acoustic seal, attenuating outside noise and preventing sound leakage. The ear tips of the ATH-CKS77 and ATH-CKS55 in-ear models are designed for with bass response in mind, with a new, movable two-position post that lets wearers adjust the ear tips for the best fit, sound isolation and low-frequency performance.

The over-ear ATH-WS70 and ATH-WS55 utilize large-diameter drivers and powerful rare-earth magnets to convey music with presence and impact. The in-ear ATH-CKS77 and ATH-CKS55 feature Audio-Technica's direct-diaphragm driver design that mounts the diaphragm assembly (the moving internal part that produces sound) directly onto the edge of the enclosure for increased performance. All models are black, and the ATH-WS55 is also available in black/red (ATH-WS55BRD). All Solid Bass headphones are compatible with the Apple iPod, iPhone, and iPad, and ideal for use with portable music players, laptops, in-flight entertainment systems and other devices.
