The Razer Hammerhead Duo steps away from the company’s typical product line. These wired earbuds aren’t just limited to gamers. While they offer little in the way of features, you’re making an investment in sound quality, rather gimmicky add-ons.

Who is it for?

The earbuds retail for ~$60 and are easy to toss into a bag without occupying much space.

  • Aesthetically, these earbuds are targeted toward gamers, but the accurate frequency response and ergonomic design make them appealing to all audiences.
  • Listeners who value accurate sound reproduction and a lightweight form factor will appreciate the Razer Hammerhead Duo.

What’s it like to use the Razer Hammerhead Duo?

The Razer Hammerhead Duo is a basic pair of wired earbuds, which isn’t said to disparage them: aluminum housings keep them lightweight and durable, while the braided cable combats tangling. Due to the angled nozzles and soft silicone sleeves, wearing the earbuds for extended periods of time is comfortable. Granted, I do wish the ear tips weren’t such dust magnets.

The earbuds use dual-drivers: one is tasked with reproducing bass frequencies while the other handles midrange and treble frequencies.

The omission of any cable management at the Y-splitter is disappointing, though, especially for $60 earbuds. What’s more, the stress relievers, particularly the one at the base of the L-shaped 3.5mm jack, aren’t very effective. Instead of ending in a plastic nub, it would be beneficial for a softer material like silicone to taper off and give the cable more support without sacrificing flexibility.

Other than that, the Razer Hammerhead Duo ‘buds are a pleasure to use. The name is derived from the dual-driver unit inside each earbud. One driver handles bass frequencies while the other is responsible for mids and treble reproduction. Listeners reap the benefits of this technology by enjoying clear, accurate playback.

An integrated mic and remote breaks up the right cable. Its sleek design is at the detriment of functionality: the buttons rest nearly flush against the module. Although it takes one or two tries to find the correct button, the option to skip tracks, adjust volume, take calls, and access your respective virtual assistant is convenient.

How do you connect the Razer Hammerhead Duo to your phone?

Since these are wired earbuds, there’s no need to pay attention to high-quality Bluetooth codecs. The Razer Hammerhead Duo return users to simpler times of plug-and-play. Of course, if your phone doesn’t have a headphone jack, you’ll need a dongle.

What do they sound like?

If you came to Razer looking for bass-heavy earbuds, look elsewhere. These have an accurate frequency response, which means they work well with a variety of musical genres and podcasts alike. As good as sound quality is, isolation falls short. Ambient noise easily permeates the earbuds which can lessen audio quality, bass notes in particular.

The Backseat Lovers’ song Pictures features reserved vocals and a controlled drum beat interspersed with guitar riffs. It opens with a single strum of an F chord to underscore Josh Harmon’s vocals. The first verse is relayed clearly. Thanks to the dual-driver technology, notes picked off the bass guitar are easy distinguishable from the accompanying electric guitar.

The second chorus at 2:24 highlights the Hammerhead Duo’s shortcomings: when multiple loud instruments are introduced the earbuds aren’t quite able to maintain the pleasing clarity heard during the intro. Harmon’s voice is masked by the electric guitars. This is avoided with the OnePlus Bullets Wireless 2, which use a triple-driver array.

Is the Razer Hammerhead Duo good for phone calls?

The microphone reproduces voices well but is prone to proximity issues.

The Hammerhead Duo is fine for phone calls so long as the microphone doesn’t brush against any clothes. This happens intermittently due to its low placement. What’s more, it doesn’t effectively cancel wind noise. If you happen to take calls while sedentary, though, voice transmission is clear with minimal echo.

For $60, the Razer Hammerhead Duo is a great pair of wired earbuds. Clarity is generally impressive and the understated design is appealing. I wish there was some way to cinch the left and right cables together and that a carrying case was provided. Those are small features to forfeit for the sound quality afforded by these, though. There’s also a Nintendo Switch edition of the Hammerhead Duo available soon. If you want a pair of earbuds with better instrumental separation and stronger bass response, get the OnePlus Bullets Wireless 2.
