Razer this year has been on the rampage of new product announcements, bringing dozens of devices to the market and entering new categories. Adding to the company's lineup, this week the company introduced its Hammerhead wireless earbuds, which promise to reduce the audio lag that Bluetooth headphones are typically known for. The headset is compatible with all Bluetooth devices and supports touch controls to control calls, music, and virtual assistants.

Razer’s Hammerhead True Wireless earbuds use a 13-mm driver with a 20 Hz – 20 KHz frequency response, a 32 ± 15% Ohms impedance, and a 91 ± 3 dB @ 1 kHz sensitivity; as well as an omnidirectional MEMS microphone with a -42 ± 3 dB sensitivity, a ≥55 dB signal-to-noise ratio, and a 300 Hz – 5 kHz frequency response. Each earbud is equipped with a 275 mAh rechargeable Li-Po battery, with Razer touting a battery life of up to three hours.

The headset connects to smartphones (or other devices) using ‘a customized ultra-low latency’ Bluetooth 5.0 connection that reduces lag in Gaming Mode (enabled in a special app that accompanies the product) down to 60 ms. Low latency is particularly useful for playing games and watching movies as audio that is lagging behind video is clearly annoying. Razer does not say whether the fast BT connection is enabled by a special piece of hardware, though it looks like the manufacturer has customized its BT-enabling chip and radio using firmware tweaks.
