Even Better Sound For premium, quality sound on par with CD and digital disc audio, the headphones are engineered to support the aptX codec. When paired, you'll have direct access to uncompromised natural sound that's as good as "wired" counterparts. A Better Sync Reaching new levels of energy efficiency so you can enjoy music and calls for longer, these wireless headphones feature the latest Bluetooth 4.1 that offer a more stable and faster connection between devices. The result being sports headphones with a lower energy consumption guaranteeing 7 hours of continuous music on a single charge. Talk With Clarity When speaking to friends using the built-in microphone, you will immediately notice how smooth and clear communication is. Employing CVC Noise Cancellation technology, outside sound is greatly reduced resulting in phone calls free from disturbance and with clearer transmission. Stable Performance Standard wireless connections can be fraught with disturbances resulting in clipped audio or dead connections. To combat this, the headphones are specifically designed with a ceramic antenna that boosts the signal strength and tolerates more interference.
