BOYA BY-AP4 Overview

If you need a compact and portable mobile audio solution, the BOYA BY-AP4 True Wireless In-Ear Headphones are an ideal option, with wire-free earbuds and a compact charging case. As you listen to your favorite playlist or podcast throughout the day, the charging case's built-in battery can recharge your earbuds for all-day power. BOYA also allows you to extend battery life by letting you use one earbud at a time. In addition to extending playback by always having one earbud charged and ready, this ability lets you enjoy audio while still allowing you to be aware of your surroundings.

All-Day Battery

Together, the earbuds provide you with up to 6 hours of playback. The included charging case's integrated battery provides an additional 16 hours of power when needed. To recharge the earbuds, simply place them inside the case and close the lid. They will automatically turn off and being recharging.

Easy Pairing

Thanks to an integrated hall switch, the earbuds will pair with each other and the last known device without requiring you to remove them from the case. Simply flip open the lid and the earbuds will turn on and begin the pairing process.

Wired or Wireless Recharging

When it comes time to recharge the charging case itself, you have two options. You can plug the included USB Type-C cable into an (optional) power adapter, or you can place the case on an (optional) wireless charging pad.
