HEAD Zverev Dampener in a pack of 2 is a signature tennis string dampener built with a high-density rubber compound to absorb vibration at the stringbed before it travels through the frame. Designed by HEAD with inspiration from the Zverev signature line, this dampener reduces string vibration and quiets the string ping on every ball contact, giving you a cleaner feel and a more focused on-court experience. The compact 1.5 x 1.5 x 0.3 cm profile fits securely between the central main strings of any standard tennis racquet and stays in place through aggressive play. Ideal for tennis players across Delhi, Mumbai, Bengaluru, Chennai, Pune, and Hyderabad.
