Razer’s New Wireless Earbuds Have Latency as Low as Their Battery Life

Razer Hammerhead Truly Wireless earbuds

Razer has announced a new pair of wireless earbuds that have been engineered with an emphasis on delivering minimal lag when playing games and eliminating the stutters and desyncing that you may have come to expect from similar Bluetooth devices.

The company says that its Hammerhead True Wireless earbuds are equipped with “customized Bluetooth 5.0” that enables ultra-low latency performance, high quality audio, and extended battery life. It’s unclear what Razer has done to customize the Hammerhead’s implementation of Bluetooth 5.0, but perhaps this is something we can elaborate on in the coming weeks if we go hands-on with the product.

In any event, that custom implementation of Bluetooth 5.0 allows the Hammerhead earbuds to deliver an audio latency of just 60ms, which isn’t as low as the latency you’d expect from wired headphones, but it’s a significant improvement over the 204ms you’d get from the Apple AirPods 2, according to testing conducted by RTINGS.com.

Besides being a bane to gamers, latency can be a problem for music and video producers, or even someone who just wants to watch Netflix with the audio and video in sync. From what we’ve read, AirPods use codecs to compensate for its audio latency in some situations. That shouldn’t be as necessary with the Hammerhead’s 60ms delay. Note however that this timing requires “Gaming Mode” to be enabled and we’re not entirely sure what that entails yet.

The earbuds are equipped with a 13mm driver and a 20-20kHz frequency response that is said to encompass “beefy bass” and “top-end clarity” when listening to music, movies, and games. While they might have a better latency for gaming, the Hammerhead earbuds are limited to a sub-par three-hour battery life, though you get up to four charges (15 hours total) from the bundled recharging case. It also takes an hour and a half to build up that three hour charge from a drained battery.

Razer announced the Hammerhead True Wireless earbuds within roughly a month of Amazon, Google, and Microsoft revealing new wireless earbuds, and the same week as Apple updating its offerings with the AirPods Pro, a new premium design with noise canceling and swappable ear pieces. The new AirPods Pro is shipping October 30 for $250 while older versions of the AirPods start at $159.

By comparison, Razer has undercut that pricing pretty significantly at $99.99—cheaper than even Amazon’s $129.99 Echo Buds, which were announced in late September and at least partially recognized for undercutting Apple’s design so drastically. The Hammerhead True Wireless earbuds are shipping now and available from Razer’s storefront. We’ve reached out for a review unit.
