The iStranger is a unique voice changing system designed to be compatible with most existing cell phones. Gone are the days of landline telephones. In the modern era of smartphones comes a new era voice changer. Simply insert the voice changers headphone jack into your cellphone, hold the iStranger to your ear like a phone receiver (see picture) and speak normally. The two voice changing modes, LOW and HIGH allow for greater disguise of different voice pitches so the user can go unrecognized by other callers. The single wire design makes the iStranger easy to connect so that setup is simplistic and straight forward. The iStranger's rechargeable battery offers 6 hours of battery life totaling nearly a full 8 hour shift of voice changing power. The system only turns on while the phone is in use, preserving the users battery life for when they need it most. Designed for portability, the durable metal housing and rubber edge will withstand normal wear and tear better than most products. Simple, powerful, a true voice changing companion.
