    This is a great little headphone amp! I'm using it to add a headphone port for my tube integrated amplifier which only has speaker outputs. The sound is clear & undistorted and there's plenty of volume available for any headphone I choose to plug in. I was expecting a larger unit based on the Amazon description of 5" x 7" - but that's the package size. The actual unit is only 2.25" x 4" so it deserves the "ultra-compact" label. This microamp has a quality feel; everything plugs in firmly and the volume controls are silky smooth. I highly recommend this to anyone wanting to add a headphone port to their audio system.

    This was perfect! I needed something so my older kids could watch TV at night without it keeping me awake upstairs. The TV doesn't have an earphone jack but it does have a pre-amp RCA outlet. This micro-amp connected with a cord also purchased from Amazon. Using 1/4-inch to 3.5 mm adapters I now have four handy headphone outlets that can be used. Volume is controlled at the amp so everyone listens at the level they prefer. To top it off, they all agree the sound is awesome through headphones rather than the speakers. Everybody is happy now.

    Estupendo amplificador de auriculares, te permite conectarle a la salida de la mezcladora y obtener cuatro salidas con su volumen individual y así controlar la mezcla, tiene un buen sonido, sin ningún ruido ni interferencia, está perfectamente fabricado, con buena calidad de materiales y un peso aceptable, para que quede estable en la colocación que desees, del precio nada que decir, creo que no puede ser mas barato para la calidad que tiene, solamente comentar, que el envío ha tardado bastante, como mes y medio, pero también tengo que decir a su favor, que me puse en contacto con att. al cliente y se me atendió con rapidez y eficiencia, artículo totalmente recomendable.Saludos,

    Behringer is great! Knew this product would work well, but didn't think it would work as well as it does! Amazing for the price.

    Very useful tool. Allows people to control their personal volume without affecting others. I use this with my band so that all four of us can hear the mix while we play.

    Using in the car with a regulated 12 volt power supply (Phimore Regulated Mobile Auto/Marine DC-DC Power Converter, 3-6-9-12 VOLTS DC; BE19) and AmazonBasics Lightweight On-ear Headphones. No heat issues with the unit, more than enough volume with the Basics headphones, much better than expected sound from inexpensive headphones. A great combination.

    Perfect, allows me to easily and directly control my own ear-phone monitor for my keyboard when on stage. I have it velcro-ed to the stand under my keyboard.

    Works exactly as expected. Combines 4 channels into one. Great for band practice or jamming with minimal setup

    This thing is fantastic and does exactly what it's intended to do. The metal enclosure give it just enough weight and durability to make it feel substantial. It's been reliable and I have no complaints
