The Razer Hammerhead True Wireless Pro are noise cancelling (ANC) in-ears. They're hybrid headphones designed for casual use and Bluetooth gaming. They have a low-latency gaming mode to help ensure that your audio and visuals stay in sync. Their companion app also offers a graphic EQ and presets, meaning you can tweak their sound to your liking.

Our Verdict

7.6 Neutral Sound

The Razer Hammerhead True Wireless Pro are good for neutral sound. Using their THX preset, they have a neutral sound suitable for most kinds of audio genres. Although they lack low-bass, their companion app has a graphic EQ and presets so you can tweak their 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
  • Bad passive soundstage.
7.4 Commute/Travel

The Razer Hammerhead True Wireless Pro are decent for commute and travel. They're decently comfortable and easy to take on the go, especially if you're into mobile gaming. They also have a low latency 'Game Mode' to help reduce audio synching issues when connected to your smartphone. Their active noise cancelling feature struggles to effectively block out bass-range noise like bus or train engines, though. 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
  • Mediocre noise isolation performance.
8.1 Sports/Fitness

The Razer Hammerhead True Wireless Pro are great for sports and fitness. These small in-ears are decently comfortable and have a stable in-ear fit, meaning they won't fall out during moderate physical activity. They're also rated IPX4 for water resistance. 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
  • Bad passive soundstage.
6.9 Office

The Razer Hammerhead True Wireless Pro are alright for office use. They're decently comfortable and don't leak too much audio, which is good if you have coworkers nearby. They also have an ANC system, and while it has a mediocre overall performance, it can still reduce 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
  • No multi-device or NFC pairing.
5.8 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 'Game Mode' that you can use to help their performance if you want to game on your smartphone.

5.7 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 passable for phone calls. The integrated mic does a good job of recording your voice, which sounds neutral, although a bit thin and muffled. You won't have a problem being understood by whoever's on the other end of the line, though. That said, the mic really struggles 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.
  • Mic has good recording quality.
Cons
  • Mediocre noise isolation performance.
  • Bad passive soundstage.
  • 7.6 Neutral Sound
  • 7.4 Commute/Travel

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.

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.

Using the THX EQ, the Razer Hammerhead True Wireless Pro have a surprisingly neutral sound profile. Although they lack a thumpy low-bass, they reproduce vocals and instruments very clearly. Their companion app also offers a graphic EQ and presets so that you can tweak their sound to your liking.

When we originally tested these headphones, we used the 'Flat' EQ. However, users have reported that the buds' placement affects their ability to achieve a proper seal. After retesting the buds, we noticed a difference between the Flat EQ and THX, and you can see a comparison between modes here. Keep in mind that the THX EQ results in a more neutral sound than the Flat EQ.

These headphones have good peaks and dips performance. Unfortunately, there's a slight mismatch between the left and right drivers throughout the frequency response. The left driver is more overemphasized in the bass range, which adds more thump, punch, and warmth to mixes. A peak in the high-mid affects the right driver more prominently, which makes vocals and instruments sound harsh. A dip in the low-treble hurts the comprehensibility of vocals and instruments in the left driver, while a peak in the mid-treble affects both drivers and makes sibilants like cymbals piercing.

The Razer Hammerhead True Wireless Pro's stereo imaging is great. The group delay is below the audibility threshold for the entire range, ensuring a tight bass and transparent treble reproduction. Although there's a peak in the phase response in the mid-mid, it's not noticeable with real-life content. As a result, the L/R drivers of our unit are 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.

Like most in-ears, these buds 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 noise isolation performance is mediocre.

That said, they do a better job of cutting down ambient chatter and can reduce some treble-range noise, like the hum of an AC unit. If you're looking for Razer in-ears with a better noise isolation performance, check out the Razer Hammerhead True Wireless 2021.

The Razer Hammerhead Pro have fair Bluetooth connectivity. You can't pair them with more than one device at a time, and they don't support NFC pairing, making it easier to pair them via Bluetooth.

They also have a lower latency 'Game Mode', which lowers their latency to 88 ms on PC, -72 ms on iOS, and 90 ms on Android.
