As someone who has worked with professional audio equipment at all kinds of live events for years, I rarely get surprised by a new wireless microphone system.
But recently, the newly launched AMSaudio E Series, especially the E300, has genuinely caught my attention.
This model has been gaining strong interest in the industry, and several colleagues have asked me the same question:
“How does it actually perform in real-world situations?”
After more than a week of hands-on testing — covering indoor conferences, outdoor performances, and high-interference environments — here are my honest impressions.
Quick Conclusion
If your budget is under ¥3,000 and you need a wireless microphone system that is stable, practical, and easy to operate, the E Series is definitely a standout option in this price range.
What makes it impressive is that AMSaudio has integrated several features typically found in higher-end professional systems, while still keeping the cost highly accessible.
That said, the positioning is clear:
The E Series is best suited for small to mid-sized setups, up to around 12 channels.
For large-scale multi-channel deployments or extremely complex RF environments, higher-tier solutions may still be necessary.

Real Testing Experience: Stable, Efficient, and Flexible
My usage scenarios are quite diverse — from small meeting rooms to open-air event hosting.
The biggest concern in these environments is always the same:
Signal drops
Interference noise
Unstable performance
Battery issues
Fortunately, the E300 handled these challenges very well.
1. Stability That You Can Trust
The E Series uses a true diversity dual-antenna receiving design, combined with an internal signal distribution system.
In simple terms:
The system continuously selects the stronger signal path in real time, greatly reducing dropouts.
I intentionally tested it in places with heavy Wi-Fi traffic, such as shopping malls and exhibition halls, and the performance remained consistently stable, with no noticeable interruptions or unexpected interference.
2. Efficient and Easy to Use
The E300 is designed to be practical not only in performance, but also in operation.
Battery Life:
The handheld transmitter delivered excellent endurance. AMSaudio claims up to 20 hours, and based on my experience, that rating feels realistic.
User-Friendly Features:
Functions such as one-key frequency scanning are extremely helpful for fast setup, especially for operators who need to be ready quickly without complex manual tuning.
3. Flexibility and Smart Interference Alerts
Another advantage is the system’s adaptability:
One receiver can work with multiple transmitter options, including:
Handheld microphones
Headset microphones
Bodypack transmitters
In addition, the system includes an interference warning feature, which provides early alerts before signal issues become serious. This is particularly useful for event professionals, allowing adjustments in advance rather than reacting after a problem occurs.
Final Thoughts
Overall, the AMSaudio E300 offers a rare combination at this price level:
Reliable wireless stability
Practical professional functions
Easy operation
Excellent value for small and mid-sized events
Its application range is very clear:
For setups of up to 12 channels, the E Series is more than sufficient for most commercial events, conferences, and live performances.
If you are currently looking for a dependable wireless microphone system that delivers professional performance without exceeding your budget, the E300 is certainly worth considering.
