Superb price/performance with a rechargeable battery
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.

Great for the price
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.

Good. Not perfect.
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.

Great value headphone amp. Surprised me how good.
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.

Being rechargeable sealed the deal
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! 🤗

Works fine for the money, buy new not used!
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.

Perfect solution for individual studio monitor mixes.
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.

Just disappointing from the beginning!
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!

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
