For phone conversation recording
Ideal for any phone conversations: When speaking on the telephone, the TP‑8 will capture both sides of the conversation for recording by your voice recorder. Just plug the TP‑8 jack into the "MIC" jack of your recorder, and put the earphone side into your ear. The TP‑8 is recommended for both cellular phones and landline phones including DECT standards. Ear pieces in three different sizes (S/M/L) are included.
