The AJB-331 is not just an elegant phone box; it’s a sophisticated recording jammer specifically engineered to block cellphone eavesdropping recording in a way that is both seamless and imperceptible. Compatible with all iPhones and Android phones, this device ensures your privacy without compromising the functionality of your smartphone.
