## Description

Product description

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: Great for wired IEM setup, Light, dependable and solid, relatively low noise - This is my first foray into IEM's and this box is perfect. I wasn't sure about IEM's and did not want to spend over $1000 for a great wireless system or roll the dice with a cheap one. A band member recommended these as they are dependable and we generally play small stages so being bound to a cable is not a big deal. The Donner box allows me to run my monitor mix directly from one of my Zoom L20 mixer's aux sends. The box is very light. As long as you use a good TRS stereo cable, the signal is clean. I bought some $50, 5 driver Linsoul KZ earbuds and the combination has given me a dependable wired IEM system. I am amazed at how well I can now hear myself and the other vocalists. our harmonies will be so much better. I find myself asking why I didn't do this before. Please note that It is necessary to have either a send that uses an XLR or to use a TRS stereo 1/4" cable or use and TRS to XLR adapter. With a straight guitar cable you will just get one side\ear. I actually kind of like that. This is a great product if you are okay with being wired.

## 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.
