--------------------------------------------------- 【Voltage Compatibility】 Our products are selected to support international voltage ranges (e.g. 100–240V). However, please make sure your local voltage is compatible before use, as incorrect voltage may still cause malfunction.

【Plug Type】 Our products use Japanese plug types (A or B type). Please use a conversion adapter if necessary.

【Important Note on Transformers and Adapters】 A transformer adjusts voltage to match your device’s requirements. A conversion adapter only changes the plug shape and does not adjust voltage. Using only a conversion adapter without a transformer may result in damage to the product.

【Liability】 We are not responsible for malfunctions or damages caused by improper use, such as operating the product without appropriate voltage or equipment. --------------------------------------------------- Chest piece and ear tubes: Material: Stainless steel Length: 73cm / Weight: Approx. 220g / Diaphragm diameter: 47mm Double-sided, all-stainless steel medical stereo stethoscope General medical device license number: 11B2X00021171001 [High-end model in the Stereophonet series] The chest piece, including the ring that holds the diaphragm, and the ear tube are made of stainless steel, which provides excellent acoustic characteristics and boasts even more outstanding auscultation performance. You can hear more detailed information such as the sound's volume and quality, as well as the sound's spread, movement, and direction of the sound source. The StereoPhonette has a structure in which the left and right sides collect and transmit sound completely independently. The chest piece is divided into left and right halves by a central partition, and each is connected to an independent two-in-one tube. This structure successfully captures important left-right auscultation sound information that is masked with conventional stethoscopes. *This diaphragm is designed to cut low frequencies and pick up mid- and high-frequency sounds. When listening to low frequencies, please use the bell side. The diaphragm side and bell side can be switched by simply turning the shaft. [Stress-free and easy-to-use functions] ■The ear tube rotates while the earpiece fits into the ear canal, reducing friction in the ear canal. The angle of the ear tubes can be adjusted to ensure a secure fit in your ear canal, preventing sound from escaping and providing a comfortable fit. ■The durable and flexible spring, which makes use of Japanese hardening technology, allows you to adjust the pressure so as not to put strain on your ear canal even when wearing the headphones for long periods of time. [Example of auscultation sounds using Stereophonette] ◇Breathing sounds Bronchial sounds and alveolar breathing sounds can be heard as a wide-ranging sound. Fine crackles caused by interstitial pneumonia can be clearly heard. Heart murmur Heart murmurs caused by turbulent blood flow are heard as directional sounds that spread throughout space. Therefore, it is easy to determine the strongest point of the heart murmur. The to-and-fro murmurs in aortic valve disease sound vivid. ◇Artificial valve sound The sound of the artificial valve closing is easy to hear. ◇Normal heart sounds Since sounds I and II are point-generated sounds, they are heard as centrally located sounds with no spread.
