Hisense 3.1Ch Sound Bar with Wireless Subwoofer HS3100

HD Voice Brings Incredible Audio Clarity to Cordless and Corded Models Support for HD Voice, also known as Wide Band audio, provides superior voice quality and clarity on all models. Standard phone calls utilize 300 Hz to 3.4 kHz bandwidth — but HD Voice utilizes 50 Hz to 7 kHz bandwidth, providing an additional two and a half octaves of voice information. The result is a rich and natural sounding voice with a dramatic improvement in clarity — bringing a new level of accuracy to speech-directed applications, such as voice-directed picking.   Built to Handle Everyday Inevitable Drops There’s no way around it — headsets will be subjected to frequent drops. Not a problem with the HS3100 and HS2100. These rugged headsets continue to operate reliably after 6 ft./1.8 m drops to concrete and 1,000 consecutive 1.6 m ft./0.5 m drops in our tumble drum, simulating the real-world tumbling that takes place after a drop. Dustproof, Sprayproof and Waterproof With IP67 sealing, the HS3100 and HS2100 headsets are virtually impervious to dust and will operate reliably, even after a hose down with high-power jetting water or complete immersion in water. Ready for the Freezer and Outdoor Subzero Temperatures Both headsets are ready for your coldest environments, delivering reliable operation in subzero temperatures as low as -22° F/-30° C. Feather-light for Extraordinary Comfort At 3.5 oz./98 g for the corded HS2100 and 4 oz./115 g for the Bluetooth HS3100, your workers will barely feel these feather-weight headsets. Superior Noise Cancellation Technology Effectively eliminates background noise to protect productivity. There is no need to repeat information, even in the noisiest environments.
