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.

This is a really great product. Good quality headphone amp. Much more headroom than I was expecting. Will drive 250ohm studio cans without any issues.

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! 🤗

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.

Disappointing from the beginning.. Purchased as a backup.. Audio quality poor.. Raised as a complaint/faulty with the supplier... Incredibly long winded process and protracted comms with the supplier.. The fault was audio sound and quality.. Or the lack of... Their best request during their process of avoiding the issue of replacement/refund which became 'death by email' was to request that I send them a video of the fault??? The issue was audio.. I rest my case.. Refund eventually actioned. I leave the rest up to you!
