Offered in small / medium and large sizes, the Anzu smart glasses feature an open-ear audio design that utilizes 16mm speaker drivers as well as an omnidirectional microphone. A touch interface on the left frame enables control over audio playback and voice assistant functionality when paired with a smartphone. Razer’s glasses rely on 60ms low latency Bluetooth for “smooth, stutter-free sound,” and provide more than five hours of runtime on a single charge. When the frames are folded up, the glasses turn off automatically to conserve power. The headset also carries an IPX4 rating against water splashes from any direction.

The Razer Anzu comes with two sets of lenses. The blue light lenses filter 35 percent of blue light from digital screens while the polarized lenses afford 99 percent UVA / UVB protection when outdoors. At $24.99, Razer’s smart glasses could easily fall into the impulse purchase category or make a great stocking stuffer for the holidays. Even if the audio quality is terrible, you’re still left with a pair of sunglasses for under $25. And if you end up really liking them, Razer has partnered with Lensabl to offer up to 15 percent off prescription lenses. Woot says the deal will be honored for five more days, or until inventory runs out – whichever comes first. According to Woot’s sales stats, 84 percent of buyers purchased one unit, 12 percent bought two and four percent scooped up three or more. Notably, there is a limit of five per customer.
