Review on Movo WMX-20-DUO: 48-Channel UHF Wireless Lavalier Mic System - 2 Transmitters & 2 Lapel Mics - DSLR Compatible (330' Audio Range) by David Moreno

Depends on what you are using them for. When you use it for a live recording or event. They are alright. The sound quality is good enough. But if you're recording for narrative work or otherwise need high-quality audio so there's no interference at all, you'll have a harder time. Prepare to seek out interference-free channels. You also need someone to monitor this disorder. Once you have that everything else will work fine, range and sound quality will be good. The 2x transmitter is a really nice plus. But I still expected it to work like a "wireless ride" where you can just check the levels and be sure the recording is good. But they are twice as expensive. Provided you take these factors into account. This is a good set for the price.
