Up to 6 hours of continuous use on a full charge. Functionality confirmed. Can be used with one earbud. Touch controls for pause and play. Noise-canceling feature. Silicone eartips are not included due to hygiene reasons. I am also selling another pair of the exact same earbuds. Those are in even better condition than these. The paint on these earbuds is peeling, so I have lowered the price compared to the other pair. For detailed specifications, please search for ATH-SQ1TW^^ #AudioTechnica #WirelessEarphones #Bluetooth #ATH-SQ1TW Price is not negotiable.
