To make your Turtle Beach headset louder, the most direct method is to use the Swarm II app on a supported model to raise the Audio Master Volume, or to check your iPhone's headphone safety settings, which may be quietly limiting your volume. These two steps resolve the vast majority of cases where a Turtle Beach headset sounds too quiet.
How to make Turtle Beach headset louder with the Swarm II app
For supported Turtle Beach headsets, the Swarm II app includes an Audio Master Volume toggle and slider that controls the overall volume of the incoming audio you hear. This is the primary method for raising volume on compatible models.
- Download the Swarm II app on a smartphone or other Bluetooth-enabled device.
- Pair your Turtle Beach headset to that device.
- Open the app and tap Get Connected.
- Use the Audio Master Volume slider and move it right to raise the volume.
For the Stealth 500 (PS Version), Turtle Beach specifies moving the slider left to lower the volume or right to raise it. For the Stealth Pro II (Xbox), the same app and slider apply.
Which Turtle Beach headsets support Swarm II
The Swarm II app is documented for these headset families or versions: Atlas Air, Stealth 500 (PS Version), Stealth 700 Gen 3 (Xbox Version), Stealth 700 Gen 3 (PC Version), and Stealth Pro II (Xbox). If your headset model is not in this list, the Swarm II app method does not apply, and you should check your device's volume settings instead.
Check iPhone headphone safety settings
Apple documents that headphone volume can be limited through Settings > Sounds & Haptics > Headphone Safety > Reduce Loud Audio. To make your Turtle Beach headset louder on an iPhone, turn off Reduce Loud Audio, or drag the slider to set a higher maximum volume. On iPhone models earlier than iPhone 7, use Settings > Sounds instead of Sounds & Haptics for volume limit settings. Apple also documents Settings > Sounds & Haptics > Volume Limit with Limit Maximum Volume and a slider on some pages, and says this applies to limiting headphone volume or speaker volume depending on the menu shown. Note that Headphone Accommodations does not work with Turtle Beach headsets, it only supports Apple and select Beats headphones such as AirPods 2 and later, AirPods Max, AirPods Pro, Apple EarPods, Beats Fit Pro, Beats Solo Pro, Powerbeats, Powerbeats Fit, and Powerbeats Pro/Pro 2.
Use iPhone volume buttons and Control Center
Apple says media volume can be raised with the volume up button on the side of iPhone. You can also change the volume in Control Center when the iPhone is locked or when using an app. These are quick checks before diving into settings menus, as the side buttons adjust audio volume during calls and when listening to songs, movies, or other media.
What about Android and other devices
Users should check their device's sound settings for volume limits or media volume controls. No separate Android volume path for Turtle Beach headsets is documented in the verified sources.
