What makes Fifine outshine other brands?It is due to our belief--Quality First, Customers Foremost. It's our enduring commitment to make endless efforts to improve our products in a leading business standard. Whether you are the teacher, broadcaster, gamer, lecturer, DJ, musician, audio engineer or videographer. You concentrate on your performance, we will focus on your equipment.No product is built to be perfect. But every product can be optimized through users' reflection and manufacturer's response. We started out the wireless lavalier microphone range from nothing, so flaw is nowhere to hide. A photographer, Ray Christofer, found out that crackling noise was heard when he was under movement. We took quick response. Within a week the issue was solved and product model was improved by enclosing the capsule with cellophane to provide better protection.Furthermore, thanks to the customers' feedback on the clip-on mic not being sensitive enough, we invented a best-suited head-worn mic in a month to help buyer get rid of soft voice problem. That is really the way and the attitude that we treat our product and customers' reflection. Our success is also due to the high standard we set for the service we provide for our customers. Fifine earns a reputation for considerate and friendly customer service. We take responsibility for both products and customers. So you can get our two-year guarantee for microphones. And whatever problems you meet and inquiries you have, our technical support department will offer in-depth support through email, phone, and social media to directly address your questions.
