The Razer Kaira Pro are wireless gaming headphones designed for Xbox One, and Xbox Series S|X consoles. They're comfortable, well-built, and have very little audio latency when connected to devices with Xbox Wireless technology. They're also Bluetooth-compatible and have a companion app with plenty of configuration options, including a graphic EQ to fine-tune their boomy, somewhat imbalanced default sound profile, and a customizable RGB lighting scheme. Unfortunately, they block out very little ambient noise and are quite bulky. Still, if you're looking for versatile wireless gaming headphones that can also cope with day-to-day use, these are a good choice.

Our Verdict

6.7 Mixed Usage

The Razer Kaira Pro are okay for mixed usage. Their bulky size and sub-par noise isolation performance limits their suitability for commuting and being worn at the gym, but they're still Bluetooth-compatible, so you don't need a dongle to connect to your phone. While they have a somewhat boomy default sound profile, their companion app features a couple of sound customization settings. Their low non-Bluetooth audio latency, comfortable fit, and excellent boom microphone make them a good option for wireless gaming.

Pros
  • Great build quality.
  • Comfortable fit.
Cons
  • Bulky design.
  • Sub-par noise isolation capability.
6.3 Neutral Sound

The Razer Kaira Pro are passable for neutral sound. These headphones struggle to deliver audio consistently. Their out-of-the-box sound profile is also somewhat unbalanced, with a boomy bass range, cluttered and muddy mids, and an underemphasized, uneven treble range. Thankfully, their companion app has audio presets as well as a graphic EQ to help you adjust their sound profile to your liking.

Pros
  • Companion app with many configuration features.
Cons
  • Middling frequency response consistency.
6.8 Commute/Travel

The Razer Kaira Pro are alright for commuting and traveling. While they're bulky and do little to filter out the rumble of bus engines, they're Bluetooth-compatible, which should allow you to connect to your phone without the use of a dongle. They have low Bluetooth latency with mobile iOS and Android devices, which is good if you like to watch videos on your way into the office. They're also comfortable enough to wear for extended periods and have a near 20-hour battery life, so they should last throughout long trips.

Pros
  • Great build quality.
  • Low Bluetooth latency with iOS and Android devices.
Cons
  • Bulky design.
  • Sub-par noise isolation capability.
7.0 Sports/Fitness

The Razer Kaira Pro are decent for sports and fitness, though this isn't their intended use. They're quite bulky and aren't likely to stay in place during intense workouts, but their wireless design eliminates the risk of an audio cable snagging on something and yanking the headphones from your head. They feel sturdy enough to take some minor drops and bumps and have a control scheme that places all essential functions within easy reach.

Pros
  • Great build quality.
Cons
  • Bulky design.
6.5 Office

The Razer Kaira Pro are a fair choice for office use. They don't block out that much background chatter and leak some audio. If your PC doesn't have Xbox Wireless technology, you won't be able to connect to multiple devices at once, though they do support Bluetooth 5.0. Their roughly 20 hours of battery life should easily get you through a couple of days at work, and they feel quite comfortable, even throughout extended listening sessions. You can also remove their boom mic to give them a more casual look.

Pros
  • Comfortable fit.
Cons
  • Sub-par noise isolation capability.
7.5 Wireless Gaming

The Razer Kaira Pro are good wireless gaming headphones. That have low non-Bluetooth latency, so you shouldn't experience a noticeable audio delay while gaming. Their boom mic also yields excellent recording quality and noise handling capability, so teammates should understand you clearly even if you're in a loud environment. Their companion app also features a broad range of configuration features, including equalizers for their sound profile and microphone.

Pros
  • Companion app with many configuration features.
  • Amazing microphone recording quality and noise handling performance.
  • Low non-Bluetooth latency with compatible devices.
Cons
  • Middling frequency response consistency.
5.7 Wired Gaming

The Razer Kaira Pro are wireless-only and can't be used on a wired connection.

7.6 Phone Calls

The Razer Kaira Pro are good for making phone calls. Their boom mic makes recorded speech sound clear, full-bodied, and detailed. It also does an amazing job of isolating your voice from ambient noise, so people should understand you clearly even if you're in a loud environment. Unfortunately, they block out very little ambient noise, so you may trouble hearing what's being said if you yourself are in a noisy setting.

Pros
  • Amazing microphone recording quality and noise handling performance.
  • Comfortable fit.
Cons
  • Sub-par noise isolation capability.
  • 6.7 Mixed Usage
  • 6.3 Neutral Sound
  • 6.8 Commute/Travel

Test Results

Design
Style

The Razer Kaira Pro are fairly simple-looking as far as gaming headphones are concerned. Their oval-shaped ear cups and simple headband design are somewhat reminiscent of the non-gaming-oriented Razer Opus Wireless, especially when you detach their boom microphone to give them a more casual look. That said, these over-ears have eye-catching lime-green accents as well as a light-up RGB Razer logo on the ear cups, which can be customized in their companion app.

These headphones are quite comfortable. They're relatively lightweight and don't clamp too tightly, with a comfortable headband and ear cups that offer a broad range of articulation for different ear shapes. Unfortunately, they're still quite bulky.

The Razer Kaira Pro have a good control scheme. It's easy to use and quite comprehensive. The left ear cup features a mic mute/unmute switch, a volume scrolling wheel, and the power button. The right ear cup has a scrolling wheel for channel mixing, an Xbox pairing button that can also be double-tapped to switch between EQ presets, and a Bluetooth multifunction button. A single press of the latter turns the headphones on and off, pauses and plays media, and answers and ends calls. Double-tapping it turns on voice commands, rejects or swaps calls, enables or disables 'gaming mode', and skips tracks forward. Triple-tapping it skips backward while holding it down for five seconds turns on the Bluetooth-pairing mode. While there's audio feedback for changes to the volume and channel mixing settings, there's no indicator for mic muting and unmuting.

The Razer Kaira Pro are very well-built. They have a high-grade plastic construction and metal ear cup hinges, so they should be able to endure a couple of bumps and drops without issue.

Stability

The Razer Kaira Pro are decently stable. They shouldn't have any trouble staying in place during casual listening sessions, but they're likely to move around or even fall off during light to moderate workouts.

Sound
Sound
Sound Profile
Bass Amount
-0.31 dB
Treble Amount
-2.21 dB

These headphones have a warm but somewhat uneven sound profile. Their overemphasized bass range is well-suited for emphasizing the thump and rumble of sound effects or EDM music, but some listeners may find it boomy. Vocals and lead instruments may be a little muddy and harsh, while their uneven treble range can result in sibilants sounding alternatively dull and piercing. Thankfully, you can adjust their sound profile via audio presets or a five-band graphic EQ in their companion app.

The Razer Kaira Pro have sub-par frequency response consistency. You're likely to experience significant deviations in bass and treble delivery depending on their fit, seal, and positioning. This could be a bigger problem if you have thick hair or wear glasses.

These headphones have decent bass accuracy. Their overemphasized high-bass range can bring out the thump and rumble of sound effects in action-heavy games, but also adds some a boomy quality to some mixes, and some users may find that they sound muddy. That said, since their bass delivery is heavily dependent on their fit, seal, and positioning, your experience may vary.

The Razer Kaira Pro have okay mid accuracy. The bump from the high-bass range carries over into the low-mids, which can clutter and muddy vocals and lead instruments. The overemphasis in the high-mids can also result in a somewhat harsh, boxy quality.

The Razer Kaira Pro have middling treble accuracy. The alternating bump and drop in the low treble range can veil finer details in vocals and lead instruments. The steep rise in the mid-treble range gives sibilants a piercing quality. Since their treble delivery is heavily dependent on their fit, seal, and positioning, your listening experience may vary.

5.7
Sound

Dips
2.79 dB

The peaks and dips performance is sub-par. The extended bump from the high-bass to low-mid range gives a boomy quality to some mixes and muddies vocals and lead instruments. The drop in the mid-mids pushes vocals and lead instruments to the back of the mix while the following bump in the high-mids makes them sound harsh and boxy. The steep dip and rise in the treble range can make some vocals and lead instruments sound a little dull and give sibilants a piercing, painful quality.

The Razer Kaira Pro have great stereo imaging performance. Their weighted group delay falls beneath the audibility threshold, resulting in tight bass and transparent treble. The L/R drivers are also well-matched in regards to phase, amplitude, and frequency response, so objects like voices and footsteps should be accurately placed within the stereo image. However, these results are only valid for our test unit, and yours may perform differently.

The weighted harmonic distortion performance is very good. Aside from a slight bit of distortion in the low-treble range at moderate and high volumes, the rest of the frequency range stays within good limits. This results in mostly clean and pure audio reproduction.

These are the settings used to test the Razer Kaira Pro.

The noise isolation performance is inadequate. They block out very little noise in both the bass and mid-range, so you're likely to hear passing buses and trucks as well as the chatter of people nearby. They do an excellent job of filtering out high-pitched ambient noise, so you shouldn't hear much of the hum of an AC unit.

The original files weren't rendered properly and we have replaced them with the correct files. The scoring of this box hasn't changed.

The boom microphone does an excellent job of isolating speech from background noise. People on the other end of the line or online teammates should understand you clearly, even if you're in a loud and noisy environment.

Note: These over-ears use Xbox Wireless technology to connect to Xbox consoles. To test latency, we used a Microsoft Wireless Adapter for Xbox One to connect the headphones to our test laptop, which doesn't have Xbox Wireless technology. We can't confirm that the measured latency is similar to when connected to Xbox One, Xbox One S, or Xbox Series S|X consoles.

Differences Between Sizes And Variants

The Razer Kaira Pro are only available in one color: 'Black', and you can see its label here. Another pair of headphones, simply designated the Razer Kaira, are similarly-designed to the Razer Kaira Pro, but don't have RGB lighting and aren't Bluetooth-compatible. We can't confirm if the headphones perform similarly overall.

If you come across a differently-configured variant, let us know in the discussions so we can update our review.

Compared To Other Headphones

The Razer Kaira Pro are Bluetooth-enabled wireless gaming headphones. They have low non-Bluetooth audio latency using Xbox Wireless technology, an eye-catching RGB lighting feature, and are well-built and comfortable. They also have a boom microphone that makes your voice sound clear and detailed, even in noisy environments. Unfortunately, they have a fairly bulky design and aren't very portable. If you're looking for alternatives, take a look at our list of recommendations for the best wireless gaming headsets, the best Xbox One headsets, and the best gaming headsets.

Xbox Wireless Headset

The Razer Kaira Pro Wireless are better wireless gaming headphones for Xbox consoles than the Xbox Wireless Headset. The Razer are better-built, have a better overall performing boom mic, and have lower non-Bluetooth latency via Xbox Wireless. However, the Xbox can also be used wired with their USB-A to USB-C cable for full audio and microphone compatibility.

Turtle Beach Stealth 700 Gen 2 Wireless

The Turtle Beach Stealth 700 Gen 2 Wireless and Razer Kaira Pro Wireless are very well-matched, so you may prefer one over the other depending on minor differences. The Turtle Beach have a tighter, more stable fit, deliver audio more consistently, take less time to charge, and have slightly lower Bluetooth and non-Bluetooth latency, though at a shorter range. Meanwhile, the Razer are comfier, have a superior boom microphone, leak less audio, and have slightly longer battery life.

SteelSeries Arctis 9X Wireless

The Razer Kaira Pro and SteelSeries Arctis 9X Wireless each have their own strengths, so which you prefer comes down to your own needs and preferences. The Razer block out a little more ambient noise, have superior mic recording quality, and lower Bluetooth and non-Bluetooth wireless latency. The SteelSeries can be used for passive audio playback with their included 1/8" TRS cable, have a better-balanced default sound profile, and last longer off of a single charge.

Razer Nari Ultimate Wireless

The Razer Kaira Pro Wireless are more versatile than the Razer Nari Ultimate Wireless. The Kaira Pro are Bluetooth-compatible, have a more stable fit, a more comprehensive control scheme, and are better-built. They also have almost four times the battery life and a superior boom microphone. That said, the Nari can be used on a wired connection via their 1/8" TRRS cable and have a slightly better-balanced sound profile out-of-the-box.

SteelSeries Arctis 7X Wireless

The SteelSeries Arctis 7X Wireless are more versatile than the Razer Kaira Pro Wireless. While both headphones are comfortable and well-built, the SteelSeries have a USB dongle that allows them to be used wirelessly with PlayStation and Xbox consoles. They also have lower non-Bluetooth latency and have better battery performance. However, the Razer support Bluetooth, which some users may prefer, and have a slightly better performing boom mic.

Corsair HS75 XB WIRELESS Gaming Headset

The Razer Kaira Pro are better than the Corsair HS75 XB WIRELESS Gaming Headset. The Razer are compatible with Bluetooth connections, block out more ambient noise, have better mic recording quality, and have a feature-rich companion app. They also have lower non-Bluetooth audio latency. Conversely, the Corsair have slightly longer battery life and deliver audio more consistently.

Bang & Olufsen Beoplay Portal

The Bang & Olufsen Beoplay Portal are more versatile headphones than the Razer Kaira Pro Wireless. The Bang & Olufsen offer better noise isolation thanks to their ANC feature, and the included audio cables offer full audio and microphone compatibility when plugged into PlayStation and Xbox controllers, although the headphones need to be turned on in order to use their TRRS cable. However, the Razer have a better microphone performance and a longer continuous battery life.
