Thinklabs One Digital Stethoscope

Thinklabs One Features: The smallest, most powerful stethoscope in the world Fits in the palm of your hand Amplifies over 100X Uses audio headphones Description: The icon of medicine has changed. The One has a standard 3.5mm jack so you can connect high quality headphones instead of old tubing style binaurals. You get better sound, more comfort, a more compact stethoscope and the choice to use the headphones of your choice. Order includes Thinklabs studio quality In Ear Headphones, with excellent bass for heart sounds and crystal-clear treble for music enjoyment. Designed for high power output, the One has dedicated headphone amplifiers, one for each channel. Voltage doubling charge pumps provide extra headroom for low distortion reproduction of S1 and S2 heartbeat peaks. The headphone amplifiers have sufficient power to drive low-impedance audio headphones, producing 45.2mWatts. Competitive stethoscopes operate on lower voltage, use a single amplifier and high impedance speaker, resulting in clipped heartbeats at significantly lower power output. The One allow you to listen with multiple filter choices. You can also set two that you use most as "favorites" that are super quick to select. So you'll have both choice and speed. Ranging from very low frequency (low pitched sounds such as S3), to higher frequencies (lung sounds) and a few in between. The One uses a rechargeable Lithium Ion battery so there's no need to replace batteries. The USB-style charger cable is included, along with compact world-wide AC charger (100-240V). The battery capacity has been designed to require only one or perhaps two charge cycles per week. Thinklink provides a connection between One and your mobile or laptop devices to capture and send sounds via iPhone, iPad, Android devices and Mac/PC. Easily switch between listening to patients or playback recordings. Thinklink is included with One. It works with all previous Thinklabs stethoscopes.
