Connect your smartphone to your headphones with microphone using the Onyx Series Auxiliary 3.5mm TRRS Audio & Microphone Cable. The TRRS (tip-ring-ring-sleeve) plug provides an extra conductor over the stereo TRS plug, allowing you to carry both stereo audio and voice over the single cable. Unlike many 3.5mm cables, the connector heads are very thin, allowing you to plug into a smartphone with the case installed. Bend tested over 5,000 times for proven long-term durability, it features aluminum connectors for an extra measure of durability..

Stereo Audio w/ Mic: TRRS (tip-ring-ring-sleeve) plugs provide 4 conductors for the ground/return, for transmitting left and right channel audio data, & for transmitting voice data from a microphone. Gold Plated: Gold plated plugs ensure smooth, corrosion-free connections every time. Durable: We bend tested this cable over 5,000 times with no damage to the cable or change in performance. The premium aluminum connectors provide an extra measure of durability. Slim Design: Our beveled step-down design creates a secure connection, while the connector heads are thin enough to plug into a smartphone with a protective case installed.
