The icon of medicine has changed. The Thinklabs 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. The Thinklabs One stethoscope includes studio quality in-the-ear headphones, with excellent bass for heart sounds and crystal-clear treble for music enjoyment.

Designed for high power output, the Thinklabs 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 allows you to listen with multiple filter presets. 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.

The Thinklabs One looks as good as it sounds. The entire case is made of metal, keys are stainless steel, and the display window is made of sapphire crystal like you'd find on a high-end watch.

Connect the Thinklabs One with your mobile or laptop devices to capture and send sounds via iPhone, iPad, Android devices and Mac/PC using Thinklink Connection System. The Thinklink is compatible with any sound recording app and allows you to easily switch between listening to patients or playback recordings. Thinklink is included with One. It works with all previous Thinklabs stethoscopes.

  1. Don't Buy It!! Review by Deafmed
    Overall Satisfaction

    I have used amplified stethoscopes for the last 19 years and this one is the least durable stethoscope I have ever used. The plastic part of one of the ear buds broke off in the first week of use which I was able to deal with because I'm deaf in one ear. Then after about 6 weeks of use a short developed in the stereo jack connection between the stethoscope and the earphones. So now I have to manipulate that connection so that I can heart my patient's heart and lung sounds. That is, until my new stethoscope comes in the mail! I will say that when it was working the sound quality was excellent and the battery really does last about 3 days. (Posted on 5/21/2016)
