  • How do I play it on my speakers?
    We are constantly updating our list of recommended models, so please check back.
  • What should I do if there is no sound coming from the Nexstetho unit?
    Nexstetho itself does not have built-in speakers, so please bring headphones, earphones, or speakers separately. We will update this page as needed for recommended equipment.
  • Can I use a chest piece other than Littmann's?
    Some connections can be made depending on the shape of the connection, but this has not been verified. Please try using the O-rings and tubes that come with Nexstetho. Please note that Littmann Master Cartiology is not compatible. If you are not sure about the installation, there is a chest piece kit with a custom-made Focal chest piece. Chest Piece Kit
  • Want to try before you buy, or want us to come to your place for a demo?

  • What causes weak or inaudible heartbeat, breath sounds, or other specific sounds?
    Sound quality often depends on the performance of headphones or earphones and speakers. Products with excellent reproduction capabilities, especially in the low frequency range of 20hz to 60hz, are desirable. We have tested the connection and sound quality, and have compiled a list of products that we believe are compatible with Nexstetho, which we hope you will refer to. (Updated as needed)

  • I have a hearing impairment and cannot perform auscultation. Can I use Nexstetho for auscultation?
    Since the degree of disability varies from person to person, some people seem to benefit from it while others do not. However, there have been reports of nurses with cochlear implants who have been able to hear again with Nexstetho. Please consult your specialist. I was so happy and moved to tears because it brought back the nostalgic feeling I had when I was healthy.
  • Can hear ambient sounds, but cannot hear heartbeat
    Depending on the situation, try the following If you feel the heartbeat is weak, press the I button on the Nexstetho main unit. Pressing the Ⅰ button will enter a mode that makes it easier to hear the heartbeat. Make sure that the chest piece is securely installed all the way to the back with no gaps or wobbling. Please use the supplied O-rings and tubes to adjust the fit. If you cannot hear the heartbeat completely, the direction of the chestpiece opening may be reversed. Please remove the chestpiece from Nexstetho once, turn the middle shaft, and then put it back.
  • Strong feedback and cannot be heard through the speakers.
    The tips to avoid feedback are as follows. Place the speaker at a distance from the main body of Nexstetho. Place the speaker facing backward. Wrap the main body of the speaker in a towel, etc. Heartbeats and other sounds are low frequency and can be heard even when wrapped in a towel. In this environment, we hope you will try to increase the volume of the speakers as needed.
