Using your iPhone 16 with a Bluetooth headset should be a seamless experience but for some users, only one side of the headset produces sound. This problem is more common than you’d expect, and while it can be frustrating, the fix is often straightforward.
In this post, we’ll break down why this issue happens and how to resolve it with step-by-step instructions.

-
Connection Instability: Weak or dropped Bluetooth signals may cause one earpiece to stop functioning.
-

-
Audio Balance Settings: Misconfigured system-level audio balance can reduce sound to one channel.
-
Hardware Faults: Physical defects in the headset or device can also cause lopsided sound.
