The Sonic Gloves are lethal sonic weapons that was created and designed by Hartley Rathaway.
After a few months of the Particle Accelerator Explosion, Hartley used this device on Rathaway Industries but set it on low power so that he can be caught by The Flash. Later Cisco was examining. He found out that Hartley used himself as bait. Hartley took a pendrive from the device and took Barry's vital signs. When Harrison Wells was giving his statement, Hartley was fixing and modifying the device. Later, he hacked into Dr. Well's comms and challenged him to send The Flash after him. Meanwhile, he was using the device to move and throw cars from the Dam. When Barry disarmed him, the device started working on its own and was killing Barry by making a strange noise. It was destroyed by Harrison Wells by sending a stronger frequency than Hartley's device.

- The wrist portions of the gloves resemble the body of either a klarinette, flute or a saxophone.
