Littmann paediatric stethoscope and infant stethoscopes are available in a range of colours. These stethoscopes are a basic style and do not include the advances of tuneable or floating diaphragms. The Cumper and Robbins Trikoph stethoscope is the most versatile stethoscope and has paediatric heads that include the latest technology. This stethoscope is also a cardiology style and has therefore a greater level of sound clarity. Welch Allyn also have a range of paediatric and infant models.
