DonnerEM1 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

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.

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! 🤗

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.

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

Brilliant, as good as any other IEM I’ve used, battery lasts a long time and being able to charge it is wonderful!

Seems to be a great piece of kit! Nice that now I don’t have to carry around batteries! Nice one donner

Works well and is cheap. Tested both over TRS in stereo and XLR in mono and looking forward to trying it live in a gig soon. For someone exploring IEM as an amateur it fits the bill.However the charge port only works with the provided USB-A to -C wire: none of my USB-C cables I have work which is a pain as I was hoping to ditch all the mini/micro/lightning adapters/cables. This also wasted me time fault-finding why it wouldn’t charge.

Nice compact unit to boost your sound for non powered earphones or when using in a noisy background.
