Alvoxcon is an amazing system under $50. My wife, featured on the cover of Women's Health magazine, is a certified personal trainer and runs online workouts for her social media followers. We just used Alvoxcon's system to film their new Unbreakable Core videos today and it worked flawlessly. Setup couldn't be simpler as you simply turn on the receiver, turn on the wireless device and sync them together in 1-2 seconds. . I should have given this 5 stars. I gave the performance 4 stars because to be honest the sound quality was good but not great. However, you'll have to shell out around $100-$150 to get a system that sounds better.
