I purchased the Adscope 615 after comparing reviews on Amazon and other sites. I also looked at the ADC website which compares the features with other ADC models and it lists the equivalent (or similar) model in the Littmann line for you to compare the features. I have some normal age-related hearing loss so for me, the clarity and volume of the Adscope 615 is a great improvement over the Adscope 603, and the Littmann Classic II for assessing blood pressure. I also like the oval shape of the diaphragm better. This stethoscope is a little heavier, but that is okay by me.
For my needs it works...light weight, easy to clean, good audio.
The ADSCOPE Platinum II Edition Single-Sided Cardiology Stethoscope is a well designed instrument. Light weight affordable and precise. The acoustics of this stethoscope is great. The ability to easily switch between low and high frequency response without rotating the chest piece is just another convenience that makes this stethoscope a great choice. It is lightweight and flexible, so virtually unnoticed when hanging around your neck for 12 hours or coiled into that cargo pocket. I highly recommend this product. Fast shipping.
The sound quality is great. You can hear the different tones depending on the pressure you apply to the bell without the hassle of flipping the bell over. Also i received my items fast and in great condition
