From D&D Wiki
 Subcutaneous Cell Phone
The recipient has a small transceiver installed underneath the skin of her throat. The transceiver is connected to a tiny speaker located in the recipient’s ear.
Benefit: The recipient may carry on conversations using the subcutaneous cell phone without raising her voice above a whisper; Perception checks made to hear the recipient suffer a –4 penalty. The tiny speaker implanted in the recipient’s ear enables her to hear the other side of the conversation, but others cannot.
