The AngelSounds JPD-100B, a heart-shaped design for easy fetal heartbeat monitoring. - Brand: AngelSounds - Model: JPD-100B - Application: Fetal Heartbeat Monitor - Color: White/Pink - Features: Heart-shaped design This is the AngelSounds Fetal Doppler Ultrasound Heart Rate Monitor JPD-100S. Purchased around June 2025 and used approximately 4-5 times between June and August. The earphones were only used by me (the wife), and my husband did not use them. A 9V battery will also be included. It takes a little practice to hear the heartbeat, but it can be heard clearly once the position is correct. (Please note that I cannot answer questions about how to use it, as the technique varies from person to person. Thank you for your understanding.) The main unit is not included as it is a medical device. Thank you for looking.
