Hearing a whizzing or cracking sound is last thing you ever want to hear and, it may even be the last thing you hear if you are being shot at! On first/third person shooter games like PUBG, being able to pinpoint the direction where hail of gunfire is coming from is essential and, that's where the HyperX Cloud Revolver 7.1 directional gaming headphones come in handy for telling the difference between a gunshot sound and the sound of the bullet passing by. You will know when the bullet shots are passing by you really close when the bullet sound goes from whizzing to a cracking/popping sound.
The HyperX Cloud Revolver 7.1 is on a league of its own when it comes to aesthetics as there is no other headset out there that looks quite like it. The Cloud Revolver 7.1 earcups have a flying saucer like design that gives the illusion the top part of the earcup is levitating on the bottom part of the earcup, housing the 50mm drivers. The split up construction of the Cloud Revolver 7.1 earcups integrates the stainless steel dual band which runs above the suspension headband. The stainless steel band integrates ridge rubber bits on the side for styling, as well as R/L markings. There is also exposed fabric cabling running from the earcup to to the headband.
Because of the deign, the Cloud Revolver 7.1 earcups do not pivot off of a yoke like other HyperX headsets such as the Cloud Stinger Core Wireless headset. The Cloud Revolver 7.1 earcups do not tilt nor swivel around, which is always good for getting a good fit on an odd-shape head. The earcups are made of hollow plastic, which makes the Cloud Revolver 7.1 headset feel a bit like an open-back headset. This means though, less passive isolation and more sound leakage than you get with the Cloud Flight S headset, which has thicker earcups that tilt and swivel.
The top and bottom of the Cloud Revolver 7.1 suspension headband is padded and covered with protein leather material that has been sewn together at the edges via overcast stitching. The word HyperX has been branded on top of the suspension headband, using an etching print. The suspension headband works, using a hard plastic self-recoiling band that slides in and out of the headband. The suspension mechanism works well and stays in place once adjusted on the head. That said, height adjustment is limited to about 3cm, which may be an issue for someone with a very tall head. The suspension headband measures 5cm wide.
Most 7.1 surround sound gaming headphones use a USB connection and that is because 7.1 virtual surround sound cannot be transmitted via 3.5mm connection, which is traditionally used for stereo sound. The neat thing about the Cloud Revolver 7.1 headset is that it can deliver both USB 7.1 sound as well as 3.5mm stereo sound, which is perfect for two reasons. One reason is that you can use the Cloud Revolver 7.1 for mobile gaming. The second reason is the sound engine of a lot of games, namely PUBG, is stereo; hence using stereo headphones is actually more beneficial for detecting directional sounds.
The HyperX Cloud Revolver 7.1 headset comes with a 7.1 surround sound dongle, which is a 3.5mm to USB-A adapter with volume remote controls. The 3.5mm female port is designed to connect the Cloud Revolver 7.1 headset into it to enable 7.1 surround sound. The 7.1 surround sound dongle has four physical volume buttons to volume up and down the volume in the headphones as well as the microphone volume. 
The buttons feel spongy a bit so, they don't have a responsive click. The 7.1 surround sound dongle measures 7cm long, 3cm wide and 2cm thick, including the shirt clip on the back of it. The 7.1 surround sound dongle is attached to a 2 meter long fabric audio cable that terminates into a USB-A connector. The HyperX Cloud Revolver 7.1 headset itself has a non-detachable fabric cable (1 meter long) that terminates into a straight rubber plug with a gold-plated 3.5mm connector.

The 7.1 surround sound dongle has two led buttons, one of which is a small button located on the side of it for enabling/disabling mute and mic monitoring. The other button is located on the front of the dongle and has a large 7.1 led in centre of it for turning on and off the 7.1 surround sound. This means, you can also use the dongle remote for stereo sound via USB connection if you don't want to use 3.5mm connection.
Both USB and 3.5mm connection deliver similar volume dynamics with different sound signatures though. With 7.1 sound disabled, the bass is more boomy, more prominent; whereas with 7.1 sound enabled the bass is more clear and less prominent, which accentuates the midrange (vocals) and treble (instruments), helping to easily identify footsteps. Via a 3.5mm connection to a computer, the bass sound is balanced with the higher frequencies. That said, when connected to the headphone jack of a phone, the volume sound is noticeably quieter, which is due to amplification and can be easily resolved with a headphone amp. Overall, if you prefer a "bassy" type sound signature, you will want to use the USB dongle remote with 7.1 sound disabled.
Total weight of the HyperX Cloud Revolver 7.1 headset (including the boom arm microphone) is 395 grams. The 7.1 surround sound dongle weighs 60 grams. The Cloud Revolver 7.1 boom arm microphone measures 13cm long and it's completely made of soft rubber. The boom arm is very flexible also, although it is not bendy; hence the microphone will not stay in place when bent at an angle.
The boom arm microphone has a 3.5mm connector at one end and, a large chamber housing a noise cancelling uni-directional microphone. Being uni-directional, the Cloud Revolver 7.1 microphone naturally blocks sound coming from the back and sides, which is ideal when gaming with other people in the same room. The noise suppression filtering helps a bit to minimize noise coming from under you, although if you have very clickity keyboard the microphone may still pick it up.
The Cloud Revolver 7.1 earpads are soft and cushiony and made with 1.5cm thick memory foam padding. Like other headphones from the HyperX Cloud family, the Cloud Revolver 7.1 earpads can be removed from the earcups, which means you can replace and/ interchange them with velour earpads, which are more breathable and cause less heat/sweat build up than leatherette earpads. The Cloud Revolver 7.1 earcups have 2cm depth and are covered with a thin layer of fabric, while the inner oval hole measures 7cm high and 5cm wide. The outer measures 11cm high and 9cm wide.
Removing the Cloud Revolver 7.1 earpads is not as easy as unclipping or twisting the earpad around and off they come. The Cloud Revolver 7.1 has the same removable earpad design as the other Cloud headphones, which is fiddly because it requires having to slip the rear bit of fabric overlay over the top of earcup while working your way around it, which takes practice.
One of the main key features that makes the HyperX Cloud Revolver +7.1 stand out from others are the directional speaker drivers, which have been angled to deliver sound similarly to directional/parametric speakers used for train station/ airport announcements. Directional speakers are also found at museums. If you live in the south east of England, one of the best places where you can experience directional/hypersonic sound is in The Wing Centre at the Battle of Britain Memorial, which houses a massive wall video exhibit with about a dozen or so directional speakers delivering sound (gunfire and huge explosions) to just that area while everywhere else is just quiet. Quite an experience!
The HyperX Cloud Revolver 7.1 headset comes packaged inside a hard box with a plastic preformed insert. You can buy the Cloud Revolver 7.1 headset directly from HyperX amazon shop. When buying the HyperX Cloud Revolver headphone be aware of the two versions - the standard Revolver headset and the Revolver 7.1 surround sound version.
