Review: Does what it says! - Tested this at home first. Plugged in headphones and powered on. Noticed a little bit of white noise, very quiet and tolerable though. Plugged in the xlr to my bass DI and it sounded great. Brought it to rehearsal. Plugged it into our mixer where a typical wireless IEM unit would get plugged in. And it worked perfect! Was able to hear the click and the full mix, plenty of volume on tap. Seems like the battery is going to last really long too. Really happy to have this for situations where I can have a wireless IEM unit. Definitely recommend for the price
Review: It is nothing fancy but it works. - It has been working just fine for several years now for our Worship Leader at church.

## Questions & Answers

**Q: do both headphone outputs get the same mix?**
A: Dear Customer, yes, the output is all the same.

**Q: can you control the volume of each headphone output independently?**
A: No, one and two headphone outputs are linked together via the large volume knob

**Q: Can I plug my electric bass directly in to this and use it as a headphone amplifier?**
A: Whoever made the 2nd answer also has no experience with the device, almost identical is not this specific device. I pluged in my bass and only got a mono signal when I used my regular guitar cable. Luckily I had a cable that has the regular 1/4 inch jack (TRS) at one end and a male XLR (circular with 3 prongs inside) on the other end, I then got a stereo sound. The only switch on the device is the on/off switch....so the switching they talk about in the description is switching the cable that you use.

**Q: Where is this made?**
A: The amplifier is made in China.

### ⭐⭐⭐⭐⭐ Good sound, Good Value
*by D***N on November 17, 2025*

I could not stand the AAA batteries coming loose in the Behringer personal amps for the IEMs we use for church worship band all the time and I was not too enthusiastic about the sound quality of the Behringer models. I went out on my own and purchasede this EM1, as it is rechargeable and has no batteries to come loose while I'm playing drums. The clarity is a noticeable difference. (I am using the MEE M6 Pro IEMs), I can say without a doubt that I prefer the compact design, sound quality and the rechageable battery of the EM1 over the behringer I was using. I had no connectivity issues, it was easy to use and the overall quality seems to be above aberage for the price. I am by no means a professional, but for practice and playing a 30 minute set each week, I am satisfied. I would buy again.
