Hola Buenas, gracias por las fotos y la información. Te quiero hacer una consulta por si me puedes ayudar, quiero instalar un circuito de Bluetooth a los cascos, lo pondría entre el cable de salida del jack y el circuito verde? Supongo que el circuito sirve para unir los cables de ambos altavoces en una sola salida.

Muchas gracias de antemano
