Hammerhead True Wireless is the first fully wireless headphone from Razer, in which the company was able to realize minimal connection delays and good sound quality. Unfortunately, there were some minuses as well, they relate to the design of the charging case, as well as the lack of the ability to quickly switch between different devices. However, this model is still suitable for those who are looking for everyday headphones without wires, which could be used including for training.

Razer Hammerhead True Wireless Bluetooth Earbuds: A Complete Review

Razer has long been developing the direction of personal audio and is primarily known as a manufacturer of gaming headphones. However, it does have a Hammerhead lineup that includes both wired and wireless models not only for games but also for music buffs. Its newest addition is the Razer Hammerhead TrueWireless fully wireless headphones, in which the manufacturer promises high-quality sound, low latency, and moisture protection. Let’s see if this is really so.

The headphones come in a cardboard box in Razer signature colours, inside of which you can also find a fabric-braided USB Type-C cable, a pair of silicone pads, a charging case, and also a cord with a clip to carry it on your hand.


Hammerhead True Wireless is an in-ear headphone with a design in the now popular case format with emitters turning into legs. The latter also has electronics, which makes the emitters themselves more compact.

But Razer decided to slightly change this design, making the legs shorter and slightly increasing the body of the speakers. Thanks to this, Hammerhead True Wireless in your ears looks more compact than Apple AirPods and Huawei FreeBuds 3, however, this can affect the usability for a number of users, so before buying this model is worth a try.

In my case, everything was fine, the Razer Hammerhead True Wireless fell perfectly into the auricle, and the special silicone tips on the emitters provided excellent fixation. These are the first in-ear headphones in which I was able to go for a run and they did not fall out of my ears. But once again I noted that this model may not be suitable for everyone because of larger emitters that can usually be found in headphones of this format.

The design of Hammerhead True Wireless is dominated by the corporate identity of Razer with black matte plastic and small glossy inserts on the outside of the case, on which the company logo is applied. They also serve to control the headphones, as they respond to touch. And on the one hand, I would like to praise this decision for responsiveness, since the sensor responds to the command literally with one touch, but on the other hand, no one cancelled accidental clicks, so sometimes playback starts already when you remove the headphones from the case.

In general, the Razer Hammerhead True Wireless look pretty, made of solid matte plastic, and also have IPX4 moisture protection, which allows them to play during any sweaty activity.

Hammerhead True Wireless Charging Case

But what was done in this model is not as soundly as we would like – this is a charging case. It is also made of matte plastic and generally looks pretty good, but it has a very flimsy cover that staggers and creaks when squeezed.

And Razer’s desire to make the case cover securely attached to its case with a magnet was to blame for everything, and the user could carry the headphones with him in his hand with a complete cord. To do this, it was necessary to lighten the lid as much as possible, therefore, unlike the rest of the case, it uses rather thin plastic.

Otherwise, there are no questions about the case; it is equipped with a light indicator and a USB Type-C port for recharging.


The headphones are equipped with Bluetooth 5.0 module and can connect to Android devices with an operating system version of at least 8.0 and iOS at least 11. For the first connection, press and hold your fingers on the touch panels on the back of the emitters for a few seconds. Unfortunately, this will have to be done with a certain frequency, since the headphones do not support fast switching between different devices. As a result, if you need to switch from a laptop to a smartphone, you must first disconnect them from the first and then connect them to the second, otherwise, the connection will not be established.

Razer Hammerhead True Wireless only supports SBC and AAC codecs, unfortunately, the manufacturer did not add aptX and aptX HD. However, this does not prevent the headphones from working normally with most devices that support Bluetooth. But there are several exceptions for which Razer made a special compatibility mode that ensures stable data transfer. These include a MacBook Pro with macOS 10.15, Huawei smartphones on Android 10, Meizu Pro 7 Plus and Redmi Note 4.

You can enable compatibility mode in the Hammerhead True Wireless app, which is available for Android and iOS. In it, you can also change the equalizer settings, but there are only three of them, without the ability to manually adjust. Otherwise, the application is only necessary to see the instruction manual.

It is worth noting that even on the headphone box, Razer indicates minimal delays in the transfer of data between the sound source and the headphones, and as shown by practical use, this is indeed so. Both on computers and on smartphones, the sound delay during playback is minimal. This is especially noticeable when watching a video. Hammerhead True Wireless also does not lose the connection between the headphones themselves, which sometimes happens in TWS headphones.

Sound and microphone

Razer Hammerhead True Wireless is equipped with 13 mm drivers, supports a frequency range from 20 Hz to 20 kHz, impedance 32 ± 15% Ohm and volume 91 ± 3 dB. In real use, these characteristics allow the headphones to create a fairly wide scene with a good margin of volume. But the main emphasis in them is on high and low frequencies, which is why the middle sags a little. But in general, the sound, as for such a compact model, is impressive. Hammerhead True Wireless lacks an active noise reduction system.

Both headphones are equipped with omnidirectional microphones, which are located on the outside of the legs. Therefore, in windy weather or in very noisy places, using Hammerhead True Wireless as a headset is not very comfortable. But otherwise, it transmits sound more or less normally.

Autonomy Hammerhead True Wireless

Built-in rechargeable batteries provide headphones with about 4 hours of playback, while the built-in 275 mAh battery in the case adds another 12 hours. To recharge the Razer Hammerhead True Wireless from 0 to 100%, you need to hold them in the case for 1.5 hours. The case itself is charged via the USB Type-C port, the manufacturer puts the appropriate cable in a fabric braid into the kit with headphones, but the power supply is not there.
