Review: As Described. Works Great - As Described. Works Great. Chasing down electrical gremlins is always a fun time
Review: ✅ easy to use, helps identify noisy circuits - I bought this product while looking to improve the powerline noise situation in my home office. I have many electronic devices powered from the same line - computers, monitors, chargers - that spew noise back and negatively affect the audio quality of desktop DACs and headphone AMPs. I found Trifield EM100 to be an equally helpful tool in measuring the line noise level and discerning between various available filter products. I wish it had a button or switch to turn OFF its speaker for those of us who keep it plugged in 24/7. Other than that, I see absolutely nothing wrong with it.

### ⭐⭐⭐⭐ Not cheap but a must need!
*by C***Z on January 24, 2026*

Hi Amazon! Definitely works well doesn’t fix anything but it can detect issues on the electrical outlet which can help determine any other issues on your audio hometheater equipment. Must have if you’re hometheater enthusiast. I recommend this product.
