Opening the box will unveil its contents. You will find the product itself with a long good quality cable that is powered via USB interface and a detachable microphone

The microphone can be installed afterward or not at all. There is no audio jack for using the headphones with an external sound source (Audio listening)

Installing the included microphone is very simple and with good length. You can rotate it at your preferred angle and at the end includes wind protection for better audio/mic quality.

There are two earcups with a 50mm driver, and the build material is PU leather. The earcups are large and follow the foam over-ear padded earcups design. The total dimension of the product is 220mm x 155mm x 95mm (LxWxH) and weights 369 grams

The product is made out of plastic at the outer shell and includes a metallic band for adjusting the length in order to fit all possible buyers. There is a lot of cushion at the headrest, while the earcups are big and have a nice texture.

Since this device is USB powered, it has a small controller that can be used to control the microphone input or disable it at all,

While in the side area, you can enable/disable the included RGB lights (static lights)

and increase/decrease the sound volume.

Wearing the SureFire Harrier 360 headset is very comfortable and each side has an L/R indicator for the proper side and a discrete RGB lighting.

The product's online pdf manual may help you with any questions you might have about the product. We used a Windows 11 machine and while the product is being advertised as 7.1 we only got Stereo Output sound. The device doesn't need any kind of driver to start working and it's recognized as USB Audio Device under the Windows operating system. This product can also be used under MAC OSX and with PS4/PS5 gaming devices.
