Razer Hammerhead True Wireless Pro Headphones Review

The Razer Hammerhead True Wireless Pro have a very similar look to the Razer Hammerhead True Wireless. They have a matte black design with similarly-sized stems and a green Razer logo on both earbud's rounded back.

The Razer Hammerhead True Wireless Pro are decently comfortable headphones. They feel more comfortable than the Razer Hammerhead True Wireless as they're in-ears with silicone ear tips. They also come with a variety of different ear tip sizes so you can find a comfortable fit for you. They don't go too deep into your ear, either. However, they're a little bulky and stick out a bit.

The Razer Hammerhead Pro have mediocre controls. All the controls can be done on either bud, and the touch surfaces are very responsive. You can tap once to answer/end calls as well as to play/pause audio. You can also tap and hold for two seconds to cycle between active noise cancelling on, off, and 'Ambient' mode, which allows you to hear sound around you without turning off your audio. You can double-tap to skip to the next track and triple-tap to return to the previous track. You can also triple-tap and hold for two seconds to turn their low latency 'Gaming Mode' on and off. Unfortunately, accessing voice assistant isn't consistent and you may accidentally change your ANC settings instead.

Like most truly wireless earbuds, these headphones are exceptionally portable. They can fit into most pockets, and their carrying case is quite small too.

The Razer Hammerhead True Wireless Pro have a decent carrying case. It's made of plastic and has an LED light to let you know when it's fully charged or charging. It should protect your headphones from minor falls or scratches.

The build quality is good. They're made of plastic but feel durable. They also have an IPX4 rating for water resistance, although we don't currently test for it. They come with a few differently-sized ear tips, and the case has a sturdy-feeling lid, especially when compared to that of the Razer Hammerhead True Wireless.

The Razer Hammerhead True Wireless Pro are stable earbuds. Although they don't have stability fins, they should stay in your ears during moderate physical exercise. However, they can fall out with higher intensity shakes.

The Razer Hammerhead True Wireless Pro have a very bass-heavy sound profile, which is well-suited for boomy genres like EDM and hip-hop. However, some users may find them a bit muddy and veiled, which hurts the presence, detail, and clarity of vocals and lead instruments. On the upside, their companion app offers a graphic EQ and presets so that you can tweak their sound to your liking.

The frequency response consistency is outstanding. Assuming you achieve a proper fit with the included tips, you should get consistent sound reproduction every time you use them.

The Razer Hammerhead True Wireless Pro's bass accuracy is mediocre. It's overemphasized across the range, resulting in extra thump, rumble, and boom that's well-suited for genres like EDM and hip-hop. However, some users may find they sound overly muddy.

The Razer Hammerhead True Wireless Pro have alright mid accuracy. There's a bit of overemphasis coming from the bass-range, which results in a muddy and cluttered sound. There's also a dip in the high-mids, so vocals and instruments sound a bit weak and distant. That said, the mid-mids are fairly well-balanced, but vocals and lead instruments sound a touch forward.

The Razer Hammerhead Pro's treble accuracy is sub-par. It's underemphasized across the range, resulting in veiled lead instruments and vocals. Sibilants like cymbals also sound a bit dull.

The Razer Hammerhead True Wireless Pro have alright peaks and dips performance. There's a peak between the high-bass and low-mid, which results in a boomy, muddy mix. There's also a dip in the low-treble, which veils vocals and lead instruments. A peak in the mid-treble makes sibilants like S and T sounds piercing.

The Razer Hammerhead True Wireless Pro's stereo imaging is fantastic. The group delay is below the audibility threshold for the entire range, ensuring a tight bass and transparent treble reproduction. The L/R drivers of our unit are also very well-matched in amplitude, frequency, and phase, which are important for the accurate placement and localization of objects and instruments (like voices and footsteps) in the stereo image. That said, these results are only valid for our unit, and yours may perform differently.

Like most in-ears, the Razer Hammerhead True Wireless Pro have a bad passive soundstage. One important factor in creating a large and spacious soundstage is the activation of the outer ear by different resonances. However, in-ears bypass the outer ear altogether, resulting in a soundstage that's perceived as small and coming from inside your head, rather than from out in front of you. They also sound less spacious than open-back headphones.

These headphones are compatible with the THX surround sound feature found in their companion app, which is part of its presets. However, we don't currently test the performance of this feature.

The Razer Hammerhead True Wireless Pro's weighted harmonic distortion performance is decent. At a normal listening volume, there are a few small peaks in the treble range, but it can be difficult to hear with real-life content. That said, they perform much better at max volume, which should result in clear and pure audio reproduction.

These are the settings we used to test these headphones. Our results are only valid when using this configuration.

Note: The THX surround sound feature is the default setting of these headphones. However, we don't currently test this feature. Instead, we tested them using the 'Custom' preset which has a flat EQ.

The Razer Hammerhead True Wireless Pro's noise isolation performance is poor. There's very little difference between their active noise cancelling (ANC) and passive noise isolating performance, which is really disappointing. Even with their ANC on, they don't block out almost any bass range noise like bus or plane engines and struggle to cut down ambient speech. That said, they can reduce some treble-range noise, like the hum of an AC unit.

The Razer Hammerhead True Wireless Pro's leakage performance is great. Most of the leakage is concentrated in the treble range. If you're listening to your audio at max volume, those around you may hear a small part of it, although it sounds thin.

These headphones have an integrated microphone.

The recording quality of the Razer Hammerhead True Wireless Pro's mic is good. Your voice sounds neutral, although a bit thin and muffled. People on the other end of the line shouldn't have too much of a problem understanding you, though.

The mic's noise handling is satisfactory. It struggles to separate your voice from moderately noisy environments, but you shouldn't have too much of a problem if you're talking in a quieter space like at home.

The Razer Hammerhead True Wireless Pro have an alright battery performance. They're advertised as having around four hours of continuous battery life, but we tested five hours, which is still quite short. That said, battery life can vary according to usage, so your experience may differ. Luckily, there are around four additional charges in the carrying case to help extend your listening time. You can also charge one earbud while using the other, which is handy.

The Razer Hammerhead Pro is a good app. Although it's simple in design, it has a 10-band graphic EQ and presets so you can tweak their sound profile. You can also remap their controls and activate their THX virtual surround sound feature.

The Razer Hammerhead Pro have fair Bluetooth connectivity. You won't be able to pair them with more than one device at a time, and they don't support NFC pairing, which could make it easier to pair them via Bluetooth. Although they have lower latency on Android, their high latency on PC and iOS may impact video streaming. They also have a lower latency 'Game Mode', which lowers their latency to 91ms on PC, 60ms on iOS, and 32ms on Android. That said, some apps compensate for latency differently, so your real-life usage may vary.

These headphones are Bluetooth-only, unlike the EPOS GTW 270 Hybrid Truly Wireless, which come with a USB-C dongle for low-latency audio playback and are also Bluetooth-compatible.

These headphones are Bluetooth-only and can't be used wired. These come with a USB-C cable to charge their carrying case.

These headphones can only be used on Bluetooth-enabled PCs and aren't compatible at all with the PS4. Thanks to their lower audio latency 'Gaming Mode', they should be suitable for gaming on PC.

These Bluetooth-only headphones aren't compatible with the Xbox One.

The case holds four additional charges and charges via USB-C.
