The 2.4GHz wireless band is considered the "junk" wireless band and with good reason - most wireless gadgets use it! Because the 2.4GHz band is so crowded, it picks up a lot of interference and that causes connection reliability issues, as well as increasing the noise floor, which isn't ideal when listening to music.
Wireless headphones typically use bluetooth or RF wireless, which is least crowded of the two. Surprisingly, there aren't actually that many 5Ghz headsets on the market and, that is despite the fact that the 5Ghz band is less crowded, has lower noise floor, faster transmission and better reliability, which is why most wireless guitar systems use 5.8GHz wireless.
If you're looking for an RF wireless headset that isn't 2.4Ghz, check out the Eksa E910 5.8GHz gaming headset (pictured). This headset has a similar construction to the E900 Pro with flat aluminium alloy yokes, padded headband (top and bottom), red led lights, plastic headband, ratchet style adjustment, metal grille earcup backing, memory foam earpads, exposed coiled cabling, volume dial and mute button.
While 2.4 Ghz has better penetration through walls, the Eksa E910 5.8Ghz headset also works well and has long range without any issues in direct line of sight. Compared to the 2.4GHz headsets, the Eksa E910 5.8Ghz can experience signal dropouts when going through walls, which is expected because 5Ghz bounces off walls, which is why most wireless headsets tend to use 2.4Ghz. Low latency is another advantage you get when using a radio frequency (Rf) wireless headset. The Eksa E910 has 15 milliseconds (ms) latency, which is lower latency than the Arctis 7. 
The Eksa E910 headset is comfortable to wear, although it weighs 304 grams, which is 50 grams heavier than the E900 Pro. The E910 earpads can be removed and replaced with aftermarket earpads too. You can even use the E900 Pro earpads as they're interchangeable. Eksa also sells E900 earpads on their website, which you can also buy. The earpads inner hole measure 6cm high and 4.5cm wide. the outer measures 10cm high and 8cm wide. The E910 earcups let out a decent amount of high sound leakage
The included 5.8Ghz dongle has a long (6cm) plastic enclosure with an audio port (3.5mm female port), which is designed to connect a phone to the dongle. To setup phone mode, you simply plug the 5.8Ghz dongle into a USB wall adapter or power bank and wait a few seconds for the dongle and headset to automatically link-up to one another. While connected to a phone, you can adjust the headphones volume (not the volume of the phone though). The audio port is disabled when the dongle is connected to a computer. 
Being a wireless gaming headset, the Eksa E910 integrates a rechargeable (1200mAh lithium) battery, which takes about 3 hours to charge via USB-C connection. The USB-C charging port deeply recessed so, you won't be able to use a right angle USB-C connector. The runtime is about 11 hours at 50% volume. In standby mode while connected, the battery can hold charge for 8 days and around 40 days when the headset is completely powered off. There is no battery status led indicator but, you will hear a ab audible beep 20 minutes before the battery runs out.
The E910 headset uses a uni-directional microphone with ENC (environmental noise cancellation) background noise suppression. The E910 mic volume gain isn't as loud as the E900 Pro omnidirectional mic but the E910 mic does a great job of removing background noise (e.g. keyboard clicky noise), which is great when chatting to friends during online multiplayer. The E910 ENC feature quiets down the volume a bit but, you can disable ENC via the software. There is no option to adjust the microphone volume or the noise suppression, which would have been neat. 
The E910 headset uses 50mm dynamic drivers, which have very high sensitivity (115dB) so, they're loud and deliver superb bass. The 2.5cm depth inside the earcup is also a plus as it helps immersion while in 7.1 surround sound, which can be enabled directly from the headset itself by pressing the power button. The E910 software integrates an equalizer and several sound presets for tweaking the stock sound signature. The E910 user interface (UI) is newer and sleaker than the UI of the E900 Pro. 
As far as accessories, you get a generous selection, including a single-headphone stand, which weighs 66 grams and measures 27cm tall. The mid-section bar is made of metal, while the 10.5cm diameter base is made of plastic. 
An unbranded audio cable and charging cable are included, as well as a thick PU leather drawstring pouch, which weighs 80 grams. The carrying pouch is large enough to fit the headphones and accessories. The audio cable is a meter long and weighs 12 grams. The charging cable measures 1.7 meters long and weighs 15 grams. You can buy the Eksa E910 headset from Eksa. If you prefer a wired gaming headset, check out the Eksa Joy Air Pro headset and the Eksa E7000 Fenrir headset, the Star Engine E5000 Pro gaming headset.
