Razer Opus X Wireless  Headphones Review

The Razer Opus X have a very similar look to the Razer Opus Wireless and Sony WH-1000XM4 Wireless. They have a sleek design with oval-shaped ear cups and lacking Razer's usual gaming logo. That said, they come in a flashy neon green color that stands out from the crowd. They also come in 'Mercury', which is bright white, and 'Quartz', which is pink.

The Razer Opus X are comfortable. They're very similar to the Razer Opus Wireless and don't put too much pressure on your head. The padding on the ear cups and the headband also feels good on the skin. However, the ear cups are somewhat shallow and if you have big ears, they may touch the edges of the inner ear pads. Your ears may also feel warm after wearing them for long periods.

The Razer Opus X have good controls. All of the controls are located on the right ear cup and are clicky physical buttons. A single press of the '+' or '-' button adjusts the volume up or down, respectively. Pressing and holding either button continually raises or lowers the volume. There's also a multi-function button. When pressed once, you can play or pause audio. For calls, this control allows you to answer a call, put a call on hold, end a call, or swap to a different call. You can press and hold this button for five seconds to enable or disable 'Gaming Mode', which offers low audio latency suitable for gaming or streaming video. A double press skips a track forward while a triple press skips to the previous track. You can use the power button to turn the headphones on and off when pressed and held. If you press it, you can also cycle between ANC on, off, or 'Quick Attention Mode', which allows you to hear your surroundings without taking the headphones off.

The multi-function button has an indentation to distinguish it from the volume buttons, and there are audio prompts when cycling between ANC and Quick Attention Mode, which you can enable or disable. There's also a chime to let you know when you've reached max volume.

The Razer Opus X have sub-par breathability. They trap in more heat than the Razer Opus Wireless, and you can feel your ears getting warm after wearing them for a while. While they're not designed for sports, if you're using them during moderate physical activities, you may sweat more than normal.

The Razer Opus X aren't very portable. While the ear cups can lay flat, these bulky headphones can't fold like the Razer Opus Wireless. They also don't come with a case to help protect them when you've placed them in a large bag. You can see another photo of the headphones in their default position here.

The Razer Opus X have a good build quality. They're very similar to the Razer Opus Wireless, but they're cheaper-feeling plastic. They have faux leather on the ear cups and headband, while the headband has metal reinforcement inside it. However, the yokes feel a bit weak and could be prone to breaking over time. Although we don't currently test for it, they also lack an IP rating for dust and water resistance, which is to be expected from over-ear headphones.

The Razer Opus X have decent stability. While they shouldn't move on your head if you're at your desk, they could fall off with higher intensity movements.

The Razer Opus X have a somewhat neutral sound profile, although the response isn't as flat as the Razer Opus Wireless. A bump in the high-bass adds extra boom to your mixes, while another peak in the low-treble makes vocals and lead instruments bright. Luckily, if you prefer a different sound, their companion app offers EQ presets to help you adjust them to your liking.

The frequency response consistency is passable. They're prone to inconsistencies in bass delivery, and you may especially notice a drop in bass if you have thick hair or glasses. They're also somewhat prone to inconsistencies in treble delivery. You may need to adjust their fit and positioning on your head to achieve more consistent treble delivery each time you use them.

The Razer Opus X's bass accuracy is very good. The low-bass is fairly flat, so your mixes have adequate thump and rumble. A peak in the mid to high-bass adds intense punch and boom. However, some users may find they sound muddy.

These headphones are prone to inconsistencies in bass delivery. Our results represent the average response and your real-life experience may vary.

These headphones have excellent mid accuracy. The overemphasis in the bass range ends in the low-mids, but it can still slightly muddy mixes. The mid-mid and high-mid are very flat and neutral, though, so vocals and lead instruments sound clear, present, and detailed.

The Razer Opus X have great treble accuracy. The low-treble has a slight peak, which makes the upper harmonics of vocals and lead instruments bright. A slight overemphasis in the mid-treble can make sibilants like cymbals piercing.

They're slightly prone to inconsistencies in treble delivery. Our response represents the average, and your real-life experience may vary.

The Razer Opus X's peaks and dips performance is good. There's a small discrepancy between the left and right driver, and the right driver has a slight dip in the low-bass, resulting in less thump and rumble. A peak in the high-bass adds extra boom and muddiness to mixes, while a dip in the low to mid-mid thins out vocals and lead instruments and nudges them to the back of the mix. A dip in the left driver's high-mid also weakens these sounds, while a peak in the low-treble makes the upper harmonics of vocals and lead instruments harsh. An uneven mid-treble turns sibilants like cymbals alternatingly dull and sharp.

The Razer Opus X's imaging performance is excellent. The entire group delay response falls below the audibility threshold, which results in tight bass and transparent treble reproduction. The L/R drivers are also well-matched in amplitude and frequency response, which is important for the accurate placement and localization of objects like footsteps in the stereo image. However, there are a couple of peaks above the audibility threshold in phase response. The peak in the low-mid was audible during our sweep and could be heard in specific content. However, the treble-range peaks shouldn't be audible with real-life content. However, our results are only valid for our unit, and yours may perform differently.

The Razer Opus X's passive soundstage performance is poor. While the soundstage seems natural, it's perceived as coming from inside your head, rather than from speakers placed around you. Since these headphones also have a closed-back design, their soundstage doesn't feel as open or spacious as open-back headphones.

The Razer Opus X's weighted harmonic distortion performance is great. Although there are a couple of very minor peaks in the treble range, they can be very hard to hear with real-life content. Most frequencies otherwise fall within good limits, which results in fairly clean and pure audio reproduction.

These are the settings used to test the Razer Opus X. Our results are only valid when using them in this configuration.

The Razer Opus X's noise isolation performance is okay. Although they have active noise cancelling (ANC), they don't block out as much ambient noise as the Razer Opus Wireless 2020 or the Razer Opus Wireless 2021. They struggle to block out the low rumble of bus and plane engines, which is disappointing if you commute a lot. That said, they do a much better job of reducing ambient chatter and the high-pitched hum of an AC unit.

The Razer Opus X have a decent leakage performance. Leakage is concentrated mostly in the mid to treble ranges and sounds somewhat thin. That said, if you like to listen to your favorite audio at high volumes, you shouldn't bother others around you if you're in a moderately noisy environment like an office.

The recording quality is fair. Your voice sounds understandable, but boxy, somewhat muffled, and lacking in body. If you're looking for wireless over-ears with a better mic performance, you may prefer the Audio-Technica ATH-M50xBT2 Wireless.

The mic's noise handling performance is sub-par. Your voice can be drowned out by moderate ambient noise like the rumble of cars passing by an open window around you. If you want to be heard clearly, you may want to take calls in a quiet environment.

The Razer Opus X's battery performance is excellent. Although they're advertised to last 30 hours with their ANC on, we measured 68 hours, which far exceeds our expectations. We verified that the ANC was on and that the volume on the headphones was maxed out. That said, we are currently retesting the battery life to confirm our original measurements.

They're equipped with an adjustable auto-off timer to help conserve battery life when you're not using them. You can also receive audio while they're charging but they don't have an AUX port, so they don't support passive playback.

The Razer Audio app is decent. You can see the battery life, change EQ presets, and adjust the auto-off timer. You can also toggle between ANC on, off, and ambient. You can connect the app to the headphones without being paired to the same phone.

The Razer Opus X's Bluetooth connectivity is satisfactory. Unfortunately, they don't support multi-device or NFC pairing. They also have somewhat high latency on PC and iOS. That said, they have a 'Gaming Mode', which is advertised to deliver low-latency audio. They have 12 ms of latency on iOS, 81 ms on Android, and 97 ms on PC, which makes them suitable for mobile gaming. It's worth noting that apps and devices compensate for latency differently, so your real-world experience may be different.

These headphones only come with a USB-C to USB-A charging cable. They don't have an AUX port, so you won't be able to use them with a 1/8" TRRS cable.

The Razer Opus X can connect to Bluetooth-enabled PCs. However, they can't connect to PCs in any other way.
