Description
The Jabra QD to 2.5mm 4-Pole TRRS Cord (8800-00-79) connects a Quick Disconnect headset to devices using a 2.5mm 4-pole TRRS jack — a format used on certain older mobile phones that need both audio and microphone on a single 2.5mm plug. It enables full-duplex headset use (voice + mic) on compatible devices.
The Telecom Spot Take
The 4-pole TRRS format on a 2.5mm plug carries both speaker and microphone on a single connector — different from a standard 2.5mm stereo plug which only carries audio. This cord is the right solution for Jabra QD headsets connecting to phones that require the 4-pole TRRS 2.5mm format for full headset functionality, including the microphone channel.
