Razer Hammerhead Duo Review

Perfectly Acceptable

Razer are one of the most well-known worldwide gaming brands. Known for their green and black aesthetic and their famous snake logo, nothing says I’m serious about gaming than sporting some Razer gear.

Over the last few years, we have seen Razer branch out to a larger consumer market than just the gaming market. Products like the Razer Opus appeal to a wide range of headphones users. The same can be said for the Razer Hammerhead Duo.

These wired earphones are great for mobile gamers looking for a great set of wired headphones, but these boast a great, accurate sound profile that might win over more than just gamers.

So, let’s find out more in our in-depth Razer Hammerhead Duo Review…

Razer Hammerhead Duo
Our rating:4.2 out of 5 stars (4.2 / 5)


These might look like a basic pair of earphones, similar to those you’d get with your phone unless you’re an Apple user. But don’t get discouraged; these are far from a standard pair of earphones.

First off, the build quality is far superior to any low-budget pair. The earphones have aluminum housings that not only make them durable but keep them lightweight. The cables are braided, which again adds a layer of durability you won’t find on most earphones.

Long-lasting comfort…

The earphones are also super comfy to wear, no matter for how long. The angled nozzles fit easily in your ears, and the soft silicone sleeves never become itchy or uncomfortable.

The earphones look great as well, with all the typical Razer aesthetics apart from RGB lighting. The logo can be found on the side of the earphones, with a black-matte like finish and green accents.

However, there are some problems…

First off, the stress relievers aren’t very great. There is only a plastic nub at the tip where the earbuds and cable meet, instead of a softer piece of silicon or rubber. Also, there is no form of cable management or Y-splitter, which is unfortunate, especially at the price these earphones are retailing for.

There is at least a microphone and an in-line remote for ease of use, but a Y-splitter would still have made them better for PC gamers who might want to use them. The in-line remote can be used for voice-assistants, which is a welcome added feature.

Our only issue with the in-line remote is how flush the button is. It can be difficult finding the button without looking, which had us pressing a few times before actually finding it.


Unlike most gaming headsets, these earphones avoid the tendency towards featuring heavy bass and stick to a more natural sound profile, to our surprise.

Such an accurate frequency response was the last thing we expected, but that is what you get.

Gives a kick…

Listening to Black Key’s “Weight of Love,” the single guitar strum, in the beginning, sounded rich before the rest of the instrumentation kicked in. With Razer’s dual-driver technology, you can really hear the bass and kick drum separately from the rest of the mix.

Dual-driver means there are two drivers in each earbud, one for the bass and one for the mid and high frequencies. This made for a pleasurable experience, with Dan Auerbach’s vocals front and center and the lively drums bashing away behind without any interference. For such small drivers, the dual-driver technology really sets these apart from most other earphones.

Tends to thin…

Unfortunately, these are still only earphones, which means the drivers can only be as big as the housing allows. This does create a shallow soundstage, which can be heard during the back end of “Weight of Love.”

The synth, guitars, and pianos all fight for their place in the mix, which leads to it sounding a little muddled. At least the bass and drums still sound great.

How does the microphone sound?

The in-line microphone isn’t that great. Since it is quite small, there isn’t much Razer can do to make it sound great.

Picking up a few phone calls during our time with the earphones, we didn’t run into any problems, and the microphone sounded fine for day-to-day conversations. Just as long as you aren’t outside in the wind or the microphone is brushing against clothing.

Other than that, the microphone sounded fine with no echoing, and voice recognition is good.

Lacking in isolation…

As previously mentioned, these earphones are quite comfy. Unfortunately, the comfort levels result in poor isolation. Now, this doesn’t mean earphones can’t be comfortable and isolate noise; it’s just that these don’t. We could still hear the rest of the office going about their day whilst playing Garena ROV, which left us a little distracted.

These also have quite a bit of leaking. So if you listen to music at loud volumes, you might get some stares from people around you.


These earphones aren’t wireless. That means if you own a new smartphone that doesn’t have any 3.5mm audio jacks, we are looking at you, Apple, then best stay away. These earphones connect using a standard 3.5mm connection. So if you only have a USB-C port, you will need the adapter to connect these.

Who is the Razer Hammerhead Duo for?

First off, these earphones are perfect for mobile gamers who want to have the gaming aesthetic brought to their mobile device setup. Even better if you already own a gaming phone, like the Razer Phone 1 and 2 or the Asus ROG phone range.

But these earphones aren’t just for gamers.

If you want a decent pair of earphones that have good sound and a premium build, the Razer Hammerhead Duo will tick all the boxes and for a reasonable price. Yes, these do cost more than your average earphones, but these aren’t average earphones, even if they do look the part.

Razer Hammerhead Duo Review Round-Up

If you want a good pair of earphones to accompany you wherever you go and prefer a wired set, then the Hammerhead Duo might be for you. They offer a well-balanced frequency response and are comfy for all-day use. They do leak some noise, but if you can get past that, you will have a pleasant user experience for a good price.

Razer Hammerhead Duo

If you prefer a wireless pair of earbuds, Razer’s Hammerhead True Wireless Earphones might be for you. If you’d prefer to stay away from gaming earphones, then Sony’s MDR-XB510AS might be up your alley. These have a powerful, bass-heavy sound profile, which will get you dancing in no time.

Until next time, happy listening.
