EM1 Rechargeable Portable Personal in-Ear Monitor Amplifier Analog Headphone Amplifier Stereo Headphone Earphone Amp Volume Control Audio Booster with XLR and TRS Input 3.5mm Output Jack

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

It has been working just fine for several years now for our Worship Leader at church.

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.

This works just fine, don't get me wrong. But I bought it before the $20 reduction and at that price I realize now that I should've got one with a DAC (iykyk). But with the $20 off and no need for a DAC, this is very good equipment and I like that is basically impossible to accidently turn off.

Great product, Great battery life, Clean sound

I received my Donner Headphone Amp on August 9, 2025. It took two weeks to set up my church sound system with a dedicated auxiliary feed so I could hear all the band members. On October 27, 2025, I was in the middle of a church service when my headphone amp died. All I could do was pull out my In-Ear Monitors and do the best I could to get through the service. I charged the headphone amp that Saturday night as always, and all seemed in order during early morning practice. The headphone amp will not reproduce sound in either input channel, and the LED's battery status will not illuminate. I went online to see if I could return the headphone amp but saw the return window had expired. I have no other recourse but to purchase another headphone amp. I am greatly disappointed with this product as I was the one trying to get the rest of the praise team to switch over to in-ear monitors. needless to say I will not purchase another product from Donner. **UPDATE** I was in the process of packing my Donner Headphone amp to send it back. I noticed I had left the amp on for two days. I decided to try charging the amp one last time and to my surprise, it starting charging the battery. I have used the Donner Headphone amp consistently for two months with no problems. I had heard a theory on battery memory where you have to completely discharge the battery before attempting to charge it completely; this may be the case. I now have no qualms in recommending this headphone amp to anyone and everyone. If you need a headphone amp with two input ports, this is the one you need. Thank you Donner for your patience.

I purchased this to replace a Behringer P1. Although the Behringer has a metal body and appears to be rugged, I have purchased 2 over the last 4 years because they simply fail. They haven't even been used all that much. I'm not sending Behringer any more of my money. I found this Donner EM1 online and purchased it. The EM1 is smaller with a plastic body and cheaper than the Behringer. I was disappointed that it was plastic. But it is much lighter and hardly feels like I'm wearing it. The P1 was so heavy, I definitely felt like it was there. If I didn't wear a belt, it made my pocket sag. The EM1 is very light. The sound quality appears no different than the P1. So far, I'm very happy with the EM1. I'll report back if it fails.

有線好きならの商品です電池長持ち 自分にはお気に入りで

On hésitait entre ce modèle et le behringer P2 qui lui fonctionne avec piles. On a opté pour celui là qui fonctionne avec une batterie luthium rechargeable. Le son est nickel on le branche en sortie de table de mixage au niveau des retours et un petit casque audio dans les oreilles, le son est top comme si le casque était branché en direct malgré les 10 m de distance avec le bloc multipaires. Donc nickel on en a commandé un second pour l'autre musicien.

No usa baterías y la nitidez es increíble

Very impressive. Haven't given them the real road treatment, but from a price point, I can buy 2-3 of these compared to the next available competitor's product, which I've now done. Fantastic volume range. Drives headphones very well and really has power for in-ear drivers. Charges quick (standard USB charger), and lasts quite a long time, hours and hours of continuous use. Combo STEREO 1/4" jack input and XLR input jack. Has an LED to show you its on, and lights up the input connector internally so you can see where to plug it in the dark. Power switch on the side is flush with the side of the case so really wouldn't get turned off accidently. Came with charge cable and an 1/8 stereo -> 1/4 TRS cable Very light. Easy to find volume knob in the dark. CONS I'm not sure if I have found, or would qualify any of the following as cons, but have to say something for a balanced review, only thing that might be an issue is the 1/4 cable might pull out, there isn't a way to lock it in. And its completely made of plastic vs metal competitors. But feels rugged plastic.
