Do You Need To Disguise Your Voice?

The Spy-MAX iStranger is a unique voice changer like no others. This is a specially designed voice changing system which will be compatible with most existing cell phones. Long gone are the days of the use of old landline telephones. In today's modern era ever increasing use of smartphones brings with it a new era voice changer.

Choose From Low or High Voice & You'll Be Unrecognizable By Family & Friends

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. There are two voice changing modes, LOW and HIGH which allows for greater disguise of different voice pitches, this way 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.

Easy-to-Use With 6 Hour Battery Life

The iStranger's rechargable battery offers 6 hours of battery life, provides 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.

Important compatibility:

To be compatible, the phone must have a 3.5mm phone jack that supports a 4-contact male connector (reference picture below). If you are unsure about which type your phone accepts, please consult its user manual or spec sheet. Alternatively, if the phone came with a microphone or headset, please count the number of divided sections. If that connector has 3 sections, the voice changer will not be compatible with your phone. If that connector has 4 sections, the voice changer will work with your phone. You may reference the picture below containing a 3 and 4 section male phone jack to determine the necessary connection type compatible with the iStranger
