The units in this sale are being sold as open box condition. That means that they have been opened due to being a photo sample, a tested good customer return or having damaged packaging. Some non-essential items may be missing from the box. The unit may not be shipped in retail packaging. That is the reason for the reduced sale price and the reduced warranty.

The Littmann Cardiology IV stethoscope offers: Better audibility of high-frequency sounds.

• Tunable diaphragms on both the adult and pediatric sides of the chestpiece
• Single-piece diaphragm that's easy to attach and easy to clean because the surface is smooth without crevices.
• Pediatric side of the chestpiece converts to a traditional open bell by replacing the single-piece diaphragm with a non-chill rim. Dual-lumen tubing eliminates the rubbing noise of traditional double tubes.
• Next-generation tubing is not made with natural rubber latex or phthalate plasticizers.
