Motorola Moto Buds 270 ANC True Wireless Earbuds Active Noise Cancellation (ANC): The buds include Active Noise Cancelling technology so external ambient noises are reduced, making listening to music or calls in noisy environments (trains, city traffic, office) much more comfortable. Environmental Noise Cancellation (ENC): For calls, there is also ENC which helps in producing clearer voice transmission by reducing background noise during phone calls. Wireless Charging Case: The Charging Case supports wireless charging, in addition to USBC charging. So you can place the case on a compatible wireless charger to top up when you're not near a Cable. Total Battery / Playback Time: On a Full charge (buds + case), you get upto 18 Hours of playtime. The earbuds themselves last ~6 hours per charge under ideal conditions. Charging & Quick Boost: Full Charging of the case takes about 2 Hours. In many cases, a short charge gives some hours of playback ( 5 Minutes of Charging gives ~2 Hours of music Playback in Some Spec sheets). Bluetooth Version & Connectivity: Uses Bluetooth 5.0. Typical range is up to 10 meters (about 30 feet) without obstructions Support for Mono Mode / Independent Bud Usage: Each bud can connect independently to the phone (master/slave auto switch). This means you can use either bud solo - useful for calls or in situations where you want one ear free. Touch Controls: Both earbuds have touchsensitive controls. You can tap to play/pause, answer or end calls, likely toggle ANC or transparency mode, etc. No physical buttons, so interaction is via taps or touch gestures. Ergonomic Design: Angled acoustic Tubes, multiple ear tip sizes (usually 3 sizes) for better fit and comfort for extended wear. We Only Sell 100% Original, Top-Quality Motorola Genuine Products.
