How can I increase and decrease the volume on Oraolo headphones?

To adjust the volume on most Oraolo wireless headphones or earbuds, you can typically use the following controls:

• Increase Volume: Short press or click the (+) button on the headset. If you are using earbuds, it is often a single tap or a long press on the right earbud (depending on the specific model).
• Decrease Volume: Short press or click the (-) button on the headset. For earbuds, it is often a single tap or a long press on the left earbud.

If your specific model does not have physical volume buttons, you may need to adjust the volume directly from your connected Bluetooth device (such as your smartphone or tablet). Since the exact button configuration can vary between models like the Oraolo M110 or M91, please check for specific touch sensors or side buttons on your device.
