Adjust Volume on JBL Charge 4

There are a few ways to adjust volume on JBL Charge 4. These depend on the app(s) you’re playing from mostly. Indeed many apps offer volume adjustment controls. But this speaker has two buttons for volume control as well. So find these (the + and -) buttons on its top side. Note though, that you cannot set volume with the JBL Connect app.

Also, we assume that you have paired your Charge 4 with your mobile device.

Adjust Volume on JBL Charge 4: Step by Step

You can adjust the volume without using any apps, doing it this way, as follows.

1. Lay Out the Charge 4 such that you See the Button Controls

See the button panel on the top. There are six buttons here. These include the Connect, Volume DOWN (-), Power, Bluetooth, Volume UP (+), and the Play / Pause button.

2. Set Volume by Pressing the – and + Buttons

Press the (-) button at the left center of the speaker to reduce the volume. Tap the (+) button at the right center of the speaker to raise the volume.

Adjust Volume on JBL Charge 4: Use Siri Voice Commands on iOS

Unfortunately, unlike the Charge 3, the JBL Charge 4 does not let you to activate Siri this way. But you can get still her attention by pressing and holding the Home button, or by calling out ‘Hey Siri’.  This works even when you pair your device with the Charge 4.  But be sure to speak into the device’s microphone, not to the Charge 4, for best results.

Command Siri to Adjust Volume

Next is an example of giving Siri a voice command to set the volume to half (50 percent).

Press that button to wake Siri up. Hold it in until she responds.  Then ask her to raise and lower the volume as follows.

Siri Responds

Next is an example of Siri responding to a voice command to set the volume to FULL (100 percent).

The Siri Volume Setting Commands Summary

Siri currently understands one scale for volume adjustment: 0-100 percent. So here we have example commands. Say these after you’ve pressed the Home button to tell her to listen.

• • Set volume 0 [muted].
  • Volume 0.
  • Set volume 10 [Ten percent].
  • Set volume 10 percent.
  • Volume 10.
  • Set volume 76 percent.
  • Volume 76.
  • Set volume 100 [One hundred percent, full volume].

There are also shortcut commands for minimum and maximum volume setting, as in:

• • Mute. [Sets the volume to zero percent, minimum, muted state.]
  • Half volume. [Adjusts volume to fifty percent, or half of full.]
  • Set volume full. [Sets speaker volume to maximum, 100 percent.]
  • Set volume max. [Sets speaker volume to maximum, 100 percent.]
  • Volume half. [Adjusts volume to fifty percent, or half of full.]
  • Volume minimum. [Sets the volume to zero percent, minimum, muted state.]

Adjust Volume on JBL Charge: Do It On the Bluetooth Source Device

You can adjust volume with the controls on the paired device.  Further, you can do the same with paired Android devices as well. But we find that volume adjustments on the speaker do not change the volume on our Samsung J7 phone. So for this phone, the volume buttons on the speaker seem to adjust the amplifiers on the speaker itself. But not the phone volume. We hear distortion in the speaker when its volume is at half.  But the phone volume is at full (100 percent). So, just be aware of this so you can avoid “over driving” the Charge 4 with your Android device.

In this demo though, we play YouTube content on an iPad Air 2. Then we stream that audio to the Charge 4.

1. Begin Playing a Music Source

Firstly, start streaming an internet radio station, a song from YouTube or Spotify, or an Audible book. So in this demo, we stream YouTube audio.

2. Use your Source Device’s Volume Control Buttons to Adjust the Volume

See this done in the next picture.

Also note that the volume change you hear on this BT speaker lags by a quarter second or so. Why? Because of the latency (delay) of the commands going across the Bluetooth airwaves to the speaker.

Finally, we’re not covering here how to set volume for individual apps. So, we leave to the reader figuring out how to do this.
