Gaming accessory manufacturer Ozone gaming have released the latest addition to their Gaming headset line-up, the Blast 4HX. Ozone claims that the Blast 4HX is optimised for both PC and consoles. The Blast 4HX boasts ease of use and possession of more functionality than comparable gaming headsets on the market. We have obtained a pair of Blast 4HX’s and in this review we will put Ozone’s claims to the test.

Outward Appereance

The Blast 4HX is colored black with orange and silver highlights. The orange lining of the cups stands out both on the outside and inside of the cups. The outer frame of the headset features a silver strip which houses red LED’s that give the headset a gentle glow.

The cups of the headset can be folded, allowing for compact and safe transportation. The microphone is also foldable to a position flush with the headset frame. The lengthy 3 metre USB cable features a control unit around the middle of the cable.


The control unit has a switch that allows the user to take advantage of pre-programmed profiles optimized for PC or consoles. The control unit also has a rather unique VOIP volume control as well as the traditional volume control. Another handy addition to the control unit is the inclusion of LED’s that light up blue when the headset is unmuted, and red if muted.

The connection varies depending on the platform. When using a PC the Blast 4HX uses the USB and

3.5mm audio connections. For use with Xbox 360 and Xbox One a 3.5mm to 2.5mm audio jack adapter is needed for the microphone which is included in the box. Using the headset with Sony PS3 and PS4 you can use the 3.5mm audio jack and USB connection or the RCA cable included.

A specialised driver is not required.  Plug and Play support means Windows happily uses generic headphone drivers automatically upon plugging in the headset to the PC.

Setup is straight forward and quick. Most users will not need to use the included quick start manual.


Ozone Gaming Gear advertises the Blast 4HX as a comfortable headset for long gaming sessions. We found this claim to be true in our test sessions.

The width of the headset frame can be easily adjusted to the size of the user’s head, which allows comfort for all head sizes. The ear pads mould to the users ears, keeping it snug and restricting unwanted movement. Additionally, the Blast 4HX is very light, ensuring comfort for extended gaming sessions


The sound test of the Ozone Blast 4HX was impressive. We started our sound test with the usual music and games where the high natural volume of the headset was apparent, even on lower volume settings.

The headset delivers clear highs and depth of sound. The bass is powerful and impressive. These qualities are especially noticeable when listening to music. The Blast 4HX showed us its true purpose when we fired up some games. The headset picked up a wide range of detailed effects in-game. The direction of footsteps and explosions/gunshots can be located very precisely.

The microphone quality of the headset was also impressive. Our testing produced crystal clear recordings with no distortion of the voice. Background noise is also filtered out quite well.
