Razer Hammerhead USB-C ANC Earphones Review

Rating: 7.0.

Razer has been manufacturing earphones for its Hammerhead series for a while now, and today we are looking at the Hammerhead USB-C ANC. The name tells you pretty much everything you need to know, straight away – these earphones have a USB-C, not 3.5mm, connector and they also sport active noise cancelling technology. Priced at £80, are these worth buying?

Over the last two years, we have overseen a period where almost all flagship phones have removed the trusty headphone jack. Whether you like it or not, it's definitely been happening and there's only a handful of phones which still have a 3.5mm connector. Audio dongles have become a temporary solution, but these are easy to lose and (depending how you use them) easy to break. Audio manufacturers like Razer, with its Hammerhead USB-C ANC, are trying to present an easier solution – creating earphones that connect via USB-C instead of a 3.5mm jack.

It's not quite so straightforward as that, however, as there's no single USB-C audio standard. Different phone manufacturers treat the USB-C port in different ways, and different earphones also treat the connector in different ways – so you can't guarantee every USB-C headset will work with every USB-C phone/device. Still, it's an intriguing market and Razer does have a compatibility list on its website – though it is far from exhaustive.

Let's see how we got on by diving right into the review.
