The A4Tech B25 wireless earbuds in Ash Grey are designed for a versatile listening experience across your PC, laptop, tablet, or smartphone. They feature 2Drumtek Signature Sound, powered by a hybrid diaphragm crafted from carbon fiber and nano mycelium to deliver a balanced audio profile. Connectivity is handled via Bluetooth v5.2, which supports quick pairing for an effortless connection after the initial setup. You can manage your media and calls using intuitive touch controls, allowing you to skip tracks, handle phone calls, or activate your voice assistant. The earbuds support independent transmission, meaning you can use just one side for calls while keeping the other in the case. Built for portability, the Ash Grey earbuds come with an aluminum charging case that provides an additional 15 hours of power beyond the 5 hours offered by a single charge, totaling 20 hours of playback.
