Three connections for gaming and everyday listening

At your computer, plug in the 2.4 GHz receiver with its USB-C connector. Cooler Master reports latency below 20 ms in its laboratory tests for this mode. Bluetooth connects the headset to a phone or another supported device without using the receiver.

CH351 remembers up to three Bluetooth devices and lets you switch between them with a button. This selects the audio source rather than mixing several streams at once. A 3.5 mm connection is also available for wired listening. The USB-C socket on the headset is for charging, not wired USB audio.

50 mm drivers with 3D Surround at the press of a button

The headset uses 50 mm drivers with a frequency response of 20 Hz to 20 kHz. In wireless mode, a button on the earcup turns the built-in 3D Surround effect on or off. You can leave it disabled when you prefer stereo playback.

The wired connection works differently. A 3.5 mm cable provides passive listening, without 3D Surround, sidetone or the headset's volume control. Adjust the volume on the source device instead. Keep this in mind if you regularly switch between wireless PC use and a headphone output on another device.

A removable microphone with optional voice monitoring

Position the flexible boom close to your mouth for voice chat, then unplug the microphone when you do not need it. Its pickup pattern is unidirectional. This is not the same as active noise cancellation, or ANC.

Sidetone feeds your own voice into the earcups during a conversation. The microphone button cycles through three settings: microphone with sidetone, microphone without sidetone, and microphone mute. These functions are intended for wireless use. The analogue 3.5 mm connection does not carry the CH351 microphone signal, so a cable alone will not provide in-game voice chat.

Up to 30 hours of battery life with cushioned earcups

Cooler Master quotes up to 30 hours of use at 50% volume, based on testing in 2.4 GHz mode. Actual battery life varies with settings and use. Charging is handled through USB-C, and the indicator shows low battery, charging and charging complete.

The adjustable headband has a padded underside, while the cushions sit around your ears. The headset weighs approximately 328 g without accessories. Cooler Master also quotes a range of up to 20 m over 2.4 GHz in laboratory conditions. Walls and wireless interference can reduce that distance.

1. How can I connect the Cooler Master CH351?

Use the 2.4 GHz wireless receiver with its USB-C connector or Bluetooth 5.4. A 3.5 mm cable is also available for wired listening.

2. Does the headset's USB-C socket carry audio?

No. The USB-C socket on the headset is for charging. The separate USB-C receiver accepts audio from the computer and sends it wirelessly to the headset over 2.4 GHz.

3. What is the latency in 2.4 GHz mode?

Cooler Master reports below 20 ms in its laboratory tests. This does not guarantee the same total latency in every computer and game setup.

4. Can CH351 remember several Bluetooth devices?

Yes, up to three. Switch between saved devices with a button. Cooler Master does not describe this as simultaneous audio mixing from three sources.

5. Does the microphone work through the 3.5 mm cable?

No. The CH351 microphone operates in wireless mode. The 3.5 mm connection provides passive audio listening.

6. What does sidetone do?

It lets you hear your own voice through the headset during a conversation. You can turn sidetone off while leaving the microphone on, or select microphone mute with the same control.

7. Can I turn 3D Surround off?

Yes, using the dedicated headset button. The built-in 3D Surround effect is unavailable over the wired 3.5 mm connection.

8. How long does the CH351 battery last?

Cooler Master quotes up to 30 hours at 50% volume, based on testing in 2.4 GHz mode. Actual results depend on settings and use. The battery charges through USB-C.

9. Is the microphone detachable, and how much does the headset weigh?

Yes, the microphone can be unplugged. The headset weighs approximately 328 g without accessories. The approximately 404 g figure includes accessories but excludes packaging.

10. Does CH351 work with PlayStation and Xbox?

Do not assume wireless support on every console. A controller with a supported 3.5 mm headphone output can provide wired listening, but not the CH351 microphone. USB or Bluetooth compatibility must be checked for the specific console.

11. How long is the warranty on Cooler Master CH351?

Cooler Master lists a 2-year limited warranty for headsets, subject to its warranty terms. Coverage applies to electrical components and excludes normal material wear.

12. How is warranty support handled for a purchase from Simline.eu?

Simline.eu accepts claims for equipment purchased from us and acts as an intermediary in the warranty process. After reviewing the documentation, we provide further instructions for handling the claim.

13. How do I submit a Cooler Master CH351 warranty claim?
