The Razer Hammerhead True Wireless Pro are in-ears with an active noise cancelling (ANC) feature. However, this feature offers a poor performance in reducing noise around you. Turning on the ANC doesn't make much of a difference, as they passively isolate a similarly low amount of noise, which is disappointing. They have a bass-heavy sound profile that some users may find boomy and muddy. Luckily, their companion app offers a graphic EQ and presets, so you can tweak their sound to your liking. They have roughly five hours of continuous playback time, but if you need more, their carrying case offers four additional charges.

Our Verdict

6.5 Mixed Usage

The Razer Hammerhead True Wireless Pro are fair for mixed use. They're comfortable, stable, and well-built, making them suitable for sports and fitness. However, whether you're on a rumbly bus or at the busy office, they don't really reduce noise around you, even with their ANC on. Their around 5-hour continuous battery life also means that they may need to recharge throughout your day. Luckily, they can be EQ'd to your liking via the companion app, and they have a lower latency mode if you want to play games wirelessly on PC.

Pros
  • Well-built and stable in-ear fit.
  • Graphic EQ and presets available.
Cons
  • Poor noise isolation performance.
  • No multi-device or NFC pairing.
6.2 Neutral Sound

The Razer Hammerhead True Wireless Pro are acceptable for neutral sound. While they have an overly boomy, bass-heavy sound profile, their companion app has a graphic EQ and presets so you can tweak its sound to better suit your needs. They also have consistent bass and treble delivery. Unfortunately, their closed-back and in-ear design can make their passive soundstage seem small and closed-off.

Pros
  • Well-built and stable in-ear fit.
  • Graphic EQ and presets available.
Cons
  • Poor noise isolation performance.
  • Bad passive soundstage.
6.7 Commute/Travel

The Razer Hammerhead True Wireless Pro are alright for commute and travel. They're decently comfortable and easy to take with you on-the-go. That said, their active noise cancelling feature doesn't block out almost any bass-range noise like bus or train engines. Their around 5 hours of playback may not last through long flights, either. Luckily, the case comes with four additional charges, and you can even use one earbud while the other charges.

Pros
  • Well-built and stable in-ear fit.
Cons
  • Poor noise isolation performance.
7.9 Sports/Fitness

The Razer Hammerhead True Wireless Pro are very good for sports and fitness. These small in-ears are decently comfortable and have a stable in-ear fit, so they shouldn't fall out during moderate physical activity. They're also rated IPX4 for water resistance, although we don't currently test for this. Thanks to their truly wireless design, there aren't any cables that could snag on something and pull them out of your ears.

Pros
  • Well-built and stable in-ear fit.
  • IPX4 rating.
Cons
  • Poor noise isolation performance.
6.0 Office

The Razer Hammerhead True Wireless Pro are mediocre for office use. They're decently comfortable and don't leak too much audio, which is good if you have coworkers nearby. Unfortunately, even with their active noise cancelling feature on, they struggle to block out ambient chatter around you. Their around 5-hour continuous battery life may also require you to take a break in your day to recharge them if you're working a 9-5 job.

Pros
  • Well-built and stable in-ear fit.
  • Graphic EQ and presets available.
Cons
  • Poor noise isolation performance.
  • No multi-device or NFC pairing.
5.3 Wireless Gaming

The Razer Hammerhead True Wireless Pro aren't recommended for wireless gaming. They can only be used via Bluetooth, which means they aren't compatible with Xbox One or PS4. While they'll connect to Bluetooth-enabled PCs, their default latency may be too high. That said, they have a lower latency 'Gaming Mode' that you can use to help their performance.

5.2 Wired Gaming

The Razer Hammerhead True Wireless Pro are Bluetooth-only headphones that can't be used wired.

6.6 Phone Calls

The Razer Hammerhead True Wireless Pro are alright for phone calls. The integrated mic does a good job of recording your voice, which sounds neutral, although a bit thin and muffled. You shouldn't have a problem being understood by whoever's on the other end of the line, though. That said, the mic can struggle to separate your voice from a moderately loud environment and is best suited for taking calls in a quieter location.

Pros
  • Well-built and stable in-ear fit.
  • Decent overall integrated mic performance.
Cons
  • Poor noise isolation performance.
  • 6.5 Mixed Usage
  • 6.2 Neutral Sound
  • 6.7 Commute/Travel

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.

Build Quality

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.

Stability

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 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 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.

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.

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 have an alright battery performance.

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 have fair Bluetooth connectivity.

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.

Differences Between Sizes And Variants

The Razer Hammerhead True Wireless Pro come in 'Classic Black', and you can see the label for our model here. If you come across another variant, please let us know in the discussions and we'll update our review.

Compared To Other Headphones

 The Razer Hammerhead True Wireless Pro are the upgraded version of the Razer Hammerhead True Wireless. With this update, Razer has improved their fit so that they're more comfortable and added another charge to the carrying case. The carrying case's lid also feels sturdier, which helps protect your headphones when you're on-the-go. These headphones have an active noise cancelling (ANC) feature, too. However, it performs very similarly to their passive isolation abilities, and overall, doesn't really block out much noise at all. Check out our recommendations for the best wireless Bluetooth earbuds, the best noise cancelling earbuds and in-ear headphones, and the best earbuds for bass.

Apple AirPods Pro Truly Wireless

The Apple AirPods Pro Truly Wireless are better headphones than the Razer Hammerhead True Wireless Pro. The Apple are better-built and have a more comfortable as well as stable in-ear fit. They also have a more neutral sound profile, and their active noise cancelling does a better job of isolating noise around you. However, the Razer have a better-performing integrated mic, and their companion app offers a graphic EQ and presets.

Sony WF-1000XM3 Truly Wireless

The Sony WF-1000XM3 Truly Wireless are better headphones than the Razer Hammerhead True Wireless Pro. While both headphones are comfortable and have similar overall battery performances, the Sony feel better-built and have a more neutral sound profile out-of-the-box. They also have a better-performing active noise cancelling feature.

Samsung Galaxy Buds Truly Wireless

The Samsung Galaxy Buds Truly Wireless are better headphones than the Razer Hammerhead True Wireless Pro. The Samsung are more comfortable and stable. Their sound profile is better-balanced as well and they can reduce more ambient noise passively than the Razer, which have an active noise cancelling feature. However, the Razer have a companion app that offers a graphic EQ.

Razer Hammerhead True Wireless

The  Razer Hammerhead True Wireless Pro are a slightly better pair of headphones than the Razer Hammerhead True Wireless. The Pro are more comfortable, better-built, and have graphic EQ and presets so that you can customize their sound profile. Their mic also offers better overall performance, and they have longer continuous battery life. While they also have an active noise cancelling (ANC) feature, it doesn't offer better noise isolation than their passive isolation performance.

Anker SoundCore Liberty Air 2 Truly Wireless

The Anker Soundcore Liberty Air 2 Truly Wireless are better headphones than the Razer Hammerhead True Wireless Pro. The Anker have a better-balanced sound profile, and even though they don't have an active noise cancelling feature, they're able to passively block out more ambient noise. However, the Razer have a better battery performance and have lower audio latency mode.

Razer Hammerhead USB-C ANC

The Razer Hammerhead True Wireless Pro are slightly better headphones for most uses than the Razer Hammerhead USB-C ANC. The True Wireless Pro are more comfortable, have a more bass-heavy sound profile which some users may like, and have a companion app with a graphic EQ and presets so you can tweak their sound. However, the USB-C ANC use a wired USB-C connection which some users may prefer since this design ensures next-to-zero audio latency. They also have a better active noise cancelling performance.

EPOS GTW 270 Hybrid Truly Wireless

The EPOS GTW 270 Hybrid Truly Wireless are more versatile than the Razer Hammerhead True Wireless Pro. The EPOS are comfier, better-built, and block out more ambient noise. They also come with a separate dongle that allows for low-latency audio, though you can't use their mic with it. Meanwhile, the Razer offer superior overall mic performance, support control remapping, and are fitted with a standby mode to conserve battery life, though they don't last as long as the EPOS on a single charge.
