Need to record your cell conversations? 
 
Connect CellTap between the 2.5 mm earpiece jack of your cell phone and your earpiece or headset. Now connect a recorder or computer sound card to the 3.5 mm mini jack output. This audio output contains a nice mix of both sides of the conversation. CellTap works with any wireless phone that accepts a third party headset or earpiece.

The CellTap does more than allow recording. Simply connect a powered speaker to the audio output jack and you will have a new conferencing capability. Everyone in the room can hear your conversation, but only the person wearing the headset can talk to the distant party. While this is not a speakerphone, in many cases it more suitable for sales presentations or contract talks.

CellTap must be used with an earpiece or headset. Your cell phone will not recognize CellTap on its own.
