Donner 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

An amazing little piece of kit. The battery lasts forever. I strongly recommend this for a cabled in-ear monitoring on stage. Much better volume and sound compared to wireless in-ear monitors.

Very happy with this, simple but very effective provides clear sound with independent volume control. Takes xlr or phono jack input. Rechargeable battery is a bonus, I've used it for 2.5hours without switching off with no problem. Strong belt clip. It is a little bit bulky on the belt, particularly if sitting down but not enough to be a problem.

What's good: It sounds just as good as my Behringer P1 but it's much smaller and lighter. It accepts jack as well as XLR. It has a rechargeable battery. It is plenty loud, and low noise. It's much cheaper than the Behringer. Not so good: The on off switch is very fiddly, you need a fingernail to work it so you can't switch it on easily on stage. I need to use the cable supplied to charge it. It doesn't charge from either of my Google USB C chargers, which is concerning. It has plastic case, whereas the Behringer is built like a tank.

Very happy with the build and sound quality, plus it's loud enough to power my IEMs but the thing that really sets this amp apart at this price level is that it's a usb-c rechargeable device - saving time and money in my opinion. I played four 1 hour sets last Saturday with two bands, the amp performed flawlessly, battery was nowhere near empty. It's grey and chunky but what do I care about that?! 🤣 Highly recommended! 🤗

Bought this for using in my home studio to adjust ear bud volume on monitoring. Worked great, lightweight and easily controlled with the large volume knob, as a guitarist standing up playing and listening to monitoring for recording I found it handy to clip on the pocket etc. The only other thing I noted was the on/off switch is flush with the side so cant be turned off accidentally. all round solid product and well packaged and comes with appropriate cables for stereo mini jack and 6mm jack. It also has an XLR/ Jack port which is great. it also charged pretty fast as well

Electronics work fine but the clip to hold the XLR cable was damaged and doesn't hold the cable in securely. As long as you don't step on the cable and pull it out by accident you're fine I guess. Sound is average, you get what you pay for really. Battery lasts for ages and pretty simple to use. Definitely recommend for anyone on a budget. Plastic casing but seems sturdy enough for regular use.

Fantastic solution for driving multiple, individual studio headphone mixes. We ended up buying several of these including some of the stereo ones too. Robust and good quality. Plus they are loud and clear sounding.

Great little personal monitor amp. Much better than the Behringer options, being rechargeable. Would have been nice if it was metal, but seems robust enouch

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.

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
