Charging Dock Casing. Having the ability to charge the headset in its carrying case can make all the difference for logistic professionals always on-the-move. With Argo 5's unique case design, the headset firmly docks during charging, yet can be conveniently accessed at any moment. 17 hours non-stop audio, 10+ hours for continuous talk and additional power via its 420mAH charging case, Argo 5 is designed for those who needs the best tools for their work. The 110 mAH battery inside Argo 5 can last 17 hours of audio playback and 10+ hours of continuous talk. Adding the 420mAH battery inside the charging case, users need not worry about running out of juice during important work. Another major concern of professionals on the road is noise, and Argo 5 address this with 2-microphones Active Noise Cancellation using the 8th generation cVc Echo Cancelling and Noise Suppression (ECNS) to reduce 96% of background sound, thus emphasizing the user's voice. Argo 5 is also the first mono earwear from Acctuone to use Qualcomm's QCC3040 chipset with bluetooth version 5.2, highlighting aptX Audio for high-quality streaming, and Multi-Point pairing for connecting to more than one device at a time, making it easy to switch between your computer and smartphone.
