The new Sleep A30 minimizes up to 30 decibels of noise with its Smart ANC technology. Its case also features adaptive snore-masking technology, which detects snoring and generates noise-masking audio that reduces the volume and frequency of snores.
You can use it wired or wirelessly, and the battery lasts months on a single charge. Switching cursor speed is easy, and it's got two customizable buttons right over the thumb. I mostly use it for forward and back, but it's super convenient. I used to get wrist pain from using regular mice, and now I have zero wrist pain.
