But the means by which the Mpow A4 squeezes-out sound quality has little to do with its hardware, and much more to do with software-side enhancements. The Mpow A4 are built around six millimeter neodymium drivers. In optimal circumstances, you should be able to get a charge in as little as 90 minutes. Though again, charge time will depend on several factors. Getting a full charge takes about two hours. That’s roughly ten days before you’ll need to think about recharging again. When you push the volume towards its limits, you’ll find the battery’s maximum lifespan creep towards 10-hours.īetween uses, the A4 supports 250-hours of standby time. 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. The chassis of the A4 is constructed with an IPX5 waterproof design, intended to keep the buds safe from rain and sweat.
