Innovative Live IQ True Wireless Earbud with Advanced Active Noise Reduction Single earbud contains one Bluetooth®5 radio for wireless connection to a smartphone or media player without the need for a wired connection between the earbuds.
Live IQ earbuds priced below $ 200 for retail customers feature touch-sensitive controls: Noise Canceling is turned on or off with a single touch, and users can choose between ambient noise, loudspeaker audio output, or mute listening. Apple Siri® and Google Assistant voice control system compatible.
Designed for Live IQ, Nuheara aims to create a noise-free, high-fidelity audio experience for earbud users with a compact, cordless, in-ear appearance comparable to large-size wired headsets. Not only do new products need to be compact and lightweight, Nuheara also hopes to provide users with long-lasting battery life in two charge intervals.
To do this, Nuheara selected the AS3412 from Amicos, which combines excellent audio performance, small size and low power consumption.The AS3412 is a highly integrated, active noise-reduction chip that measures only 2.2mm x 2.2mm x 0.4mm, and requires few external components. It achieves up to 30dB of noise reduction in the audible audio range of 20Hz to 3kHz. The AS3412's integrated amplifier can drive 2x34mW in a 32Ω circuit. At an audio output of At 30mW, the AS3412 offers 112.5dB signal-to-noise ratio and less than 0.01% total harmonic distortion and noise figure.
The AS3412-based ANC system occupies a very small footprint, enabling Nuheara to create a stylish, compact design for Live IQ earbuds, giving consumers comfortable, longer-time, noise-free listening.
With a charge of 4 hours or 12 hours of continuous music playback, the low power consumption of the AS3412 helps Nuheara to extend battery life by operating from 1.6V to 1.8V with a nominal power consumption of only 8mW.
Christian Feierl, Marketing Manager, Amicus Semiconductor Audio Sensors, said: "We are constantly pushing the performance boundaries of ANC technology and are pleased to see that our products are used in cutting-edge, consumer-grade audio equipment. We are proud to be helping Nuheara be the first to The market offers smart earplugs manufacturers with exceptional ANC performance up to 30dB of noise reduction. The small, low-power ANC chipset from Amicos Semiconductors enables Nuheara to mix ANC with unrivaled superior audio quality in smart earplugs.
Justin Miller, CEO of Nuheara, said: "The noise reduction performance of the AS3412 is far superior to other products on the market today, and Amathis has unparalleled expertise in the industry." In combining noise reduction systems with mechanical and acoustic characteristics, The leading technology and design guidance provided by Mice Semiconductor brings great help to the design team of Live IQ earplugs.
Nuheara's new Live IQ earbuds will be on display at CES 2018. Visit the Nuheara booth (# 44746) and the Ames Semiconductor booth (# 41555, smart home market).
