This is a BRAND NEW, NEVER USED Thinklabs ONE Digital Electronic Recording Headphone Amplified Stethoscope. The smallest, most powerful Stethoscope in the world. Fits in the palm of your hand. Amplifies over 100X. No bulky or awkward headset required. Uses ANY STYLE audio headphones OR sync it to your hearing aids through Bluetooth with a streamer. This ThinkLabs ONE was purchased for a hearing impaired student who did not end up completing med school. It was never taken out of the box. Our pricing beats other sellers, because we are motivated to move this single item that we have, because we don't have use for it. Includes: - Thinklabs ONE Digital Stethoscope - Thinklabs Studio Performance In-Ear headphones (excellent bass for heart and guttural sounds, crystal-clear treble for music) - Thinklink connection system for iPhone, iPad, Android, PC/Mac - USB-type Charger 100-240V - Pocket carrying case - 2 Year Thinklabs Warranty Headphones: 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. Audio Power: ThinkLabs ONE is designed for high power output, with 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. There's just no comparison. Filtering: ThinkLabs ONE allows 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. ThinkLabs ONE's Hertz Scale gives you a relative idea of the filter range you have selected. LEDs to the left indicate that lower frequencies will be reproduced. LEDs to the right indicate higher frequencies will be reproduced. The more LEDs are on, the wider the range of frequencies, the narrower the indication, the narrower the range of frequencies for the filter you have selected. For instance, you may want to narrow the bandwidth to filter ambient noise or select for very specific heart sounds, such as listening to valve clicks but exclude breath sounds while doing so. Changing Diaphragm Pressure - In addition to the filter setting, you can also change the frequency response by applying more or less pressure on the diaphragm. This is a feature of Thinklabs patented Electromagnetic Diaphragm technology. As you push on the diaphragm, the "gap" in the sensor changes, which modifies the sensor's response to lower frequencies. As shown, the bass response increases significantly with pressure on the diaphragm. This adds an exquisite, tactile sense to using the ThinkLabs ONE - like playing a musical instrument. Battery: ThinkLabs 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. Battery Level is indicated on the 0 - 10 scale to easily check remaining capacity. There are multiple warning levels, so ThinkLabs ONE will warn you well ahead of the time you need to recharge your stethoscope. Features: ThinkLabs ONE uses materials and parts not usually found in stethoscopes: - high strength sapphire crystal, robust enough to be used in deep sea chronometers - precision machined aluminum, hand-polished by people who work with satellite systems and other advanced applications requiring perfect finish - specialized electronic components that are custom manufactured for Thinklabs - gold-plated connectors and jacks to ensure low impedance connections - design refinements that focus on minutiae that get the last detail of performance ** All apps are available in the App Store and Google Play ** Thinklabs Stethoscope App - Record and visualize heart sounds on your iPhone or iPad - Scroll and zoom in/out with a multi-touch interface - Edit, save, and email sounds - Send images, videos, sounds, and notes Thinklabs iMurmur App Watch, listen, and learn: - Portable Heart Sound Reference Library - Real patient recordings/photos with notes and email capability, perfect for teachers and students TapeMachine App - Android This Android App provides many features suitable for Phonocardiography, recording, teaching, sharing stethoscope sounds around the bedside or classroom. - Record, Trim, Save, change playback speed. - Share via almost any Android communications apps: Email, Whatsapp, Dropbox, text messaging, etc.
