Here’s a photo review of disassembling the Garrett Z-lynk wireless system kit. There are two parts to this system: the Garrett WT-1 (transmitter) and Garrett WR-1 (receiver).
Other info about the Garrett Z-lynk is collected here (news, tests, comparisons, reviews and opinions). A teardown of the MS-3 headphones (the same Garrett Z-lynk technology) is here.
