ERZHEN Wireless Microphones | Cordless Microphone | UHF Microphones #U4000

I bought the system a few years ago and have been using it professionally for smaller productions ever since. The frequency is fixed, so you can’t switch to another channel, but the microphones work without interference. The sound isn’t bad at all — it’s not on the same level as an SKM5200 with a Neumann capsule, but it’s definitely a lot more durable.

To my ears, the sound is comparable to the Sennheiser EW100 system. I did a side-by-side test and found the range to be about the same. One of the mics occasionally experiences some transmission disturbances, though that might’ve been due to something else operating in the same frequency range.

**Verdict:** Definitely not bad. Having just one fixed frequency isn’t always ideal, especially in crowded RF environments, but for karaoke or home entertainment, this system is a solid choice. Even for pro use, it holds up surprisingly well.

And yes — I own several original professional Sennheiser systems with Neumann heads, and yes — I still use this system regularly. After over 200 professional performances, I think it’s fair to say: these mics are durable and offer decent sound at an affordable price.
