These battery estimates suppose that you’re making modest use of the volume. Mpow A4 Bluetooth Headphones are built around a high-performance polymer lithium battery, offering about 13-hours of battery life. The base of the in-line console is also where you charge the built-in battery. Having only three buttons means multiple-button operation becomes necessary, but the added complexity is minimal. The volume buttons are separated by the central media button, making operation without looking very easy. The console has three multifunction buttons, which allow you to raise and lower volume, skip through tracks, and play/pause music.

The Mpow A4 moved these controls onto an in-line console. That can create any number of issues as you struggle to navigate a tiny control panel, especially if the device is positioned against the side of your head. Totally wireless earbuds are often forced to place control buttons on an earbud. Though they might survive momentary submersion, you certainly don’t want to tempt fate by throwing them in a pool. That’s actually one of the lower waterproofing certifications. Ultra-stable earplugs will always stay in your ears.The chassis of the A4 is constructed with an IPX5 waterproof design, intended to keep the buds safe from rain and sweat. Retractable earbuds allow you to adjust the wires to the required length, no worry about being tangled.
