This service allows you to send in your bluetooth cable and upgrade the installed module (PLUSSOUND or PS-V3) for the latest (choose between TWS-C or TWS-A) module. TWS modules are designed specifically for use with in-ear monitors regardless of sensitivity and includes longer battery life and EQ presets for sound tuning. Click on TWS-A and TWS-C to learn more.

Instructions: Please ship BT cable to the address shown in your order receipt after order has been placed. If you did not receive it, log in on our website using your email address to view your order details.

Note: This service is only for installing new module and battery. For other services (cable modifications, repairs, etc.), please contact us at sales@plussoundaudio.com.
