Product Descriptions

Herda ensures a one-year warranty for all purchases. Should you encounter any queries or issues, feel free to contact our expert team for swift resolutions.

Note 1: To confirm compatibility of connection with your own earpiece, helmet intercom, or hearing aids, your Bluetooth device should be Bluetooth 3.0 or above, and must support both HSP (Headset Profile) and HFP (Hands-free Profile) Bluetooth protocols. Devices using only the A2DP (and AVCRP) profile are not supported. Please refer to your device manufacturer’s specifications to confirm profile support.
