I'm currently using a similar product and love it so much that I bought another one for my family. However, they decided they preferred Apple products... sigh. So, I'm selling this brand new, unopened item, still in its shrink wrap. Even though I'm selling it, I have to say it offers performance and ease of use that exceeds its price. * Bluetooth 5.3 * QCC3072 Bluetooth Chip * aptX Adaptive Codec * IPX5 Waterproof Rating * Up to 43dB ANC (Active Noise Cancellation) * cvc8.0 Call Noise Cancellation Technology * 55ms Low Latency Mode * Up to 33 Hours of Continuous Playback * Supports Multipoint Connection * Compatible with the EarFun App Other features: Noise Cancelling
