The glasses that double as headphones have become an increasingly popular category.After Bose launched its version in 2019 and Amazon launched Echo Frames in 2020, the next big company to jump on the trend was Razer.It officially unveiled the Anzu smart glasses today, which filter out blue light and project audio into your ear without completely drowning out ambient sound.
The main difference between Anzu and Echo Frames is that blue light filtering seems to be the default feature in the Razer version.While you can install prescription lenses on the Echo frame, the standard options are clear, with no sun or blue light protection.
Based on rendering, Anzu looks very similar to Echo Frames in terms of overall volume.In other words, they look equally compact.But, according to the spec sheet, Anzu weighs about 10 grams more than Echo Frames.While Amazon only offers one lens shape, Razer has a choice of round or rectangular lenses that you can wear for Anzu to turn into sunglasses.It’s unclear whether Anzu will be available in a variety of colors, including the company’s signature green, but Amazon’s product comes in three.
Just as Echo Frames, Anzu provides touch controls via a side panel that you can adopt to manage music playback, to accept or reject calls, activate phone assistants or turn on “game mode.”They use a custom Bluetooth 5.1 connection that delivers a 60 millisecond delay and prevents audio lags.In addition, Razer promises “more than 5 hours of battery life” and up to two weeks of backup power when you’re not actively using the device.There is also an omnidirectional microphone on the board, so your callers would be able to hear you.
Provided you demand prescription lenses to work along with Anzu, you could purchase them by Razer’s partner.
