4 Channel Headphone Amplifier with 3 Input Mute & Audio Mixer, Mono/Stereo Audio Amplifier, Ultra-Compact Headphone Amp Splitter 1/4" & 1/8" TRS Output for Studio and Stage with Power Adapter

First off, I'd say if anyone is looking for a stellar average review of anywhere near 80% or better having a large number of consumers reviewing them for any of these types of comparable products.... you're fooling yourself. I use high end Pro Audio equipment and it's not cheap so you have to consider the price you're paying. Even comparable items higher in price are rating subpar on satisfaction so that's my disclaimer here.That said, I've purchased and tried a few of these multi-output headphone amps and this one has worked relatively well for me. The biggest advantages of this one over the others (for me) is the power button and front facing outputs.I purchased it for use on my iMac Pro for working away of my studio. The desk space I have is somewhat limited and I don't like clutter so having the headphone jacks facing me conserves the space in back of the unit free of more cables and etc.The power button appears to be somewhat of a rare find for mostly all of the others I've seen. This is huge for me b/c I don't like having things setting and just draining electricity when I'm not using them; and having to manually disconnect and reconnect just doesn't seem a viable option. Turning on and off as needed is a nice convenient option. Also requiring only 5V as opposed to 12V isn't bad either.I would have easily given this product a 5 star had it not been that I began hearing the audio drop in volume in either the left or right via the headphones. Placing my hand near the unit or sometimes just moving the jack in the connection would restore the volume which leads me to believe there may be some faulty connection inside the unit with the electronics or a ground loop problem. Not a deal breaker b/c overall it has worked out well for the purpose.I have a 2K+ headphone amp for serious studio work but for simple monitoring and etc. This unit fills the bill just fine.Pros:PortabilityPower ButtonFront facing output jacksAmplificationCons:Audio Signal may drift if output port is faulty

Excelente producto y sonido

Volume controls were scratchy out of the box, but needed for a job so couldn't return it. Hopefully won't get worse with time. Good features and good construction/feel.

Great sound, with multiple inputs.

Un gran articulo para el precio !!! la calidad de sonido es muy fiel a la fuente que se esta amplificando, los controles de volumen son buenos (tiene mucho volumen !!! mas de lo recomendado), los materiales de construcción son buenos, los cables en general aceptables pero ! el adaptador de corriente no es de buena calidad, recomiendo cambiarlo, en general es un gran gran articulo !!!

Reemplace mi antiguo amplificador de audifonos por mejora profesional y por la facilidad de usar dos tipos de conectores. Los músicos son un caso descontrolado y, mal usan los conectores entonces, el tiempo de grabación es valioso mientras se lucha con los conectores A, simplemente llegar y conectar lo que necesite tu audifono.Muy robusto y elegante: Recomendaría despegar los Knobs un poco de la base para que la sensacion sea más placentera al subir o bajar volumen y no se raye el metal por ende, dure más estéticamente.Las entras que ofrece: mini, grande y Rca. Sin duda lo hacen destacar por encima de muchos incluso, de marca. Recomendado por un productor musicalEXCELENT OPCION POR PRESUPUESTO, AUNQUE NO SEA PROFESIONAL

Excelente

I'm using this device to control the audio output from my desktop pc between two separate tube-amps, 1 pair of solid-state amplified speakers, and a large subwoofer, thus using all 4 of the gold plated 1/4-inch jacks are always in use. The other smaller 4 jacks were all tested and work as well. We appreciate the metal case and the price. It's heavy enough to not be easy to move around on a table.UPDATE: Currently I'm now experiencing some extreme high levels of noise from this device. All the troubleshooting points to this device creating the noise. Already I'm in the market for a better mixer. I had not noticed the noise upon first review, and if anything, it's gotten much worse over time. Too much for my ears, I'm getting a better brand.

I'm not an "audiophlie", so feel free to ignore this review if you think this disqualifies me. I do, however use this connected to Baerdynamic DT 770 Pro headphones while watching movies (projected on a 14 foot screen) and have never felt like I needed more. The dials are smooth and never once produced static or flaws. Controls feel precise. The metal case feels quality for the price. I'm satisfied that it does what I want.

Belle finition : du métal pas du plastique, tout en façade pour les prise casque, peu encombrant et efficace pour amplifier les casque avec haute impédance.Manque de rétroéclairage pour les potentiomètres quand on travail dans la pénombre.Sinon bon rapport qualité prix

Spinge da matti anche con cuffie difficili. Si differenzia dagli altri modelli perche' ha 3 ingressi differenti ed escludibili che (cosa ottima!) sono miscelabili seppure a volume fisso. Questo mi consente di entrare con il mio basso attivo e "suonare sopra" una base collegando all'altro ingresso il telefonino/player. Inoltre (importantissimo!) ha il tasto mono/stereo fondamentale quando si usa con ear monitor sulla mandata di un mixer live che spesso ha uscite mono su un unico canale. Altro vantaggio: funziona a 5Volt con cavo usb il che mi consente di usare live un power bank invece dell'alimentatore. Bello pesante e robusto, mi ha stupito per qualita' e flessibilita'.

Completo a nivel de conexiones, aunque le vendría de lujo una entrada XLR, supera a la mayoría de sus competidores, y mucho más si se tiene en cuenta su precio.El sonido es correcto, sin ruidos de fondo y con un nivel de ganancia más que adecuado.Yo le tengo conectado un piano Roland fp10, que saca muy poco volumen por la salida de cascos, una interfaz de audio y un ordenador, todo de forma simultánea.Lo uso con unos AKG que necesitad de 135 ohmios para sonar adecuadamente.Totalmente recomendable

Alles super gelaufen, Ware schnell versendet, der 4 Kanal Kopfhörerverstärker funktioniert hervorragend - ich sage Danke!!! 👍👍👍👍👍
