This stethoscope is extremely sensitive. It can catch sounds from the lowest to the highest of frequencies and with a dual tube, lets you hear clearly from both ears. Its enhanced design lets you work with the device without the need to come in contact with patient's skin. Lastly, a pliable ear tip makes this stethoscope easy to use. Constructed of soft rubber, it will fit securely but comfortably in the ear but will not shift while conducting an examination.
