We use these at our church to give the musicians a stereo headphone monitor. We use to run mono, but upgraded our board to a model that had enough aux outputs to move to stereo. We had to replace our mono headphone amps and these are great. They are not very expensive and work very well. We actually power them using the 9v battery option just to keep the stage looking a little cleaner. The batteries have lasted several weeks now and haven't needed to be replaced. They are used about 3 hours each week, so that isn't a ton, but we've gotten at least 12-15 hours of use on the 9v and haven't replaced them yet. They can be powered by a continuous power supply however if you don't want to use batteries. The volume control is nice and big and the other controls/buttons are well labeled and easy to use. If you need to convert an XLR output to use with headphones, this is a great product to use.

Great quality, sounds clear, volume is just right, work well with my mix 5

As a traveling musican, I have been using this in place of a personal mixer for live performances. I am a keyboardist and need feed a direct line to the left channel. Then I feed a custom mix from the house to the right. This is typically the same mix in the wedge. But for some shows where we have a professional sound company, I can get an additional custom mix to the Right channel.This feeds my in-ear mix. This unit has a Mono/Stereo option; so, i can mix both channels to both ears. Use the main volume to control over all level. And then I use the pan to gain my direct keyboard mix and custom monitor mix.Its small like a walk-man... showing my age... so very portable. Just be sure to carry a XLR to 1/4" female converter for quick cabling when needed. Sounds great. Economical. Great purchase

The P1 is a good option start using in ears without the cost of a wireless unit. If you're a keyboard player or a drummer this might be a good solution for you.This unit is well constructed and feels solid in your hands. It has a number of mounting options using either a the built in belt clip or the built in microphone mount which will work with either US or EU standard fittings. The P1 gives you the option to have stereo input or two individual channels in at the flip of a switch. This gives you extra flexibility if you need to add audio from things like a metronome in a live situation. It also has the option for either a 9v battery or a power adapter.I have to ding this unit a star for a few reasons. The headphone output is a little low and might not Have enough power for some headphone models. While overall the construction is good, the battery door isn't great. It also doesn't have an option for a 1/4" input, leaving you out of luck in some situations if you don't have the correct adapter.The lack of power might protect a few peoples hearing by not letting them turn the volume up too high on their in ears and the concept is great. I feel like we're due for an update for this and it's sister model the P2. I would recommend this to people who need to have a power adapter, and/or two channels. For everyone else I'd go with the P2 which costs less and has more output power. The biggest downside to the P2 is that the belt clip is garbage and will easily bend out of shape if you have something snag and pull on your belt pack.

Works great, great price.

The product is amazing, lightweight and it is durable, great quality.Battery life is good

OK, so let me start out by saying I have a LONG history with Behringer products. Most of my experience has been so-so at best. Starting in the early days with the reverse-engineered, made in China clones of dbx, Mackie, Aphex and others - the quality has always been hit and miss but for me, mostly misses. Recently, Behringer seems to have switched gears (somewhat) and are buying up some pretty well known manufacturers and making an effort to establish themselves as a legitimate pro audio leader. So I have been paying attention to their more recent offerings. I play drums and use IEMs. When I needed a headphone amp, I started looking at all of the usual suspects. Price was not the main concern - I don't mind paying for quality gear - but I am not a gear snob either. The Behringer had some pretty cool features, including XLR inputs, a mic stand mount, and a belt clip. It was decently small and for under $50.00, I figured it was worth checking out. If I hated it I could always return it. A year later, I am still using it. It fits the bill pretty nicely for me. Is it audiophile quality? No. However, given the environment it has enough output and headroom to work well for me. The low end is solid and the top end does not seem overly harsh. Be careful though - if you are using consumer earbuds you may not get the same results. I use custom molded triple driver ear monitors that are up to the task and offer a lot of isolation from the ambient drum and stage volume. Even so, the P1 is usually run near the top of its output range. Be careful that you run a clean signal to it, and don't overdrive the inputs (but this is true for ANY headphone amplifier). There are a few negatives - but considering the price of the unit, it definitely earns 4 stars. The negatives - (1) No power supply is included which is really pretty silly given its intended application. The battery option is nice, but probably not used much. This is a wired unit, meaning you are going to be relatively stationary - so a power supply over a battery is a no brainer. (2) XLR inputs only. Would be nice if one of the XLRs was a combo connector that could be used with a TRS input for a stereo feed. Depending on what you are sending, you may need some extra cabling. (3) Limiter cannot be bypassed. I prefer to use the compressor/limiter on my console or IEM processor as it is much more musical and exact. I get it as a safety feature for novices - but make it a jumper or something internal that has to be intentional and that would likely discourage most people that may not hear the difference anyway from bothering with it. Overall, this unit was a pleasant surprise. And since its been a year since I purchased it - it has proven reliable thus far.Update 11/28/2023 - I have had this unit for 6 years, used almost weekly, without a failure. Even with the shortcomings mentioned, it deserves a 5 star rating for reliability alone so I have updated this review.

Resultó ser la solución perfecta para mi monitoreo en vivo, trabajo con secuencias y también necesito un monitoreo de la Banda. Tenia mis reservas respecto al volumen de behringer por las críticas que había leído pero esto no resultó ser cierto, todo depende de la señal que envíes desde tu fuente, si es baja obviamente no tendrás mucho pero si haces el trabajo correcto el equipo funciona excelente.

Ok ok

Performed exactly as hoped. XLR straight in out of the "monitor out" of my board. Using in ear monitors we've made a huge improvement (reduction) of stage volume for musicians without impacting the audience.

Dislike - 9 V battery and no auto offLike - quality and rugged and compactGreat for wired onstage monitoring with IEM

I am play drums. In our studio we have Studio monitors. it was difficult for me to hear others as soon as I start playing. I was searching for a cheap solution for on stage/studio IEM aplifier. I have found this in amazon. "E Square AV" has shipped within 4 days from Mumbai to Bangalore. It was brand new and sealed. Here is my review:Pros:+ Good build quality+ Good quality switches+ Power on/off saves battery+ Low battery indicator+ clear sound+ I can easily clip it on my pant/belt in the back easily+ 3.5mm IEM out+ amplifier produces enough sound for the IEMsCons:-- Battery slot is very tight, Its takes time to remove and place a new battery. I have envie rechargeable 9v battery. Its too tight. I heard Duracell fits perfectly but need to try. Once it put the battery, to lock the battery cover , I need to put magic tape else it comes out after locking as it has a tight foam pad. But this is not a deal breaker considering all other features.I am very much satisfied. It does its job.
