The Realme Buds Air 5 offer a total playback time of 38 hours and active noise cancellation, allowing you to fully enjoy your music anytime and anywhere. Thanks to the high-quality built-in microphone, your calls are crystal clear. The Realme Buds Air 5 headphones support noise cancellation of up to 50 dB. Additionally, they can filter out most low-frequency noise, such as the sounds from airplanes, buses, subways, and other modes of transportation. They also suppress noises from household appliances, so you can listen to music without interruption. The headphones feature a transparency mode. If you want to hear the sounds of your surroundings, simply turn on the transparency mode to continue your conversation even while wearing the headphones. The connection is made via stable Bluetooth 5.3, which reduces power consumption and stabilizes the signal. This allows you to maintain a strong connection while dozens of devices are in the area. You can easily pair them with your phone, tablet, or laptop.
