Behringer MICROAMP HA400 Ultra-Compact 4 Channel Stereo Headphone Amplifier

I got one of these to allow my wife or I to listen at whatever volume we want while keeping the TV speakers muted so the other person can sleep. It works just as I wanted and expected it to. The only problem is that it uses 1/4" TRS jacks for the input and outputs. This is fine if you're using it with standard recording studio/musician's connectors and cables, and of course, that's the market this amp was designed for. I think the manufacturer would sell a TON of these if they made a version with RCA jacks for the input and 1/8" TRS jacks for the headphone outputs. That would match what most consumers will have coming from their TV these days and what they'll find on their headphones/earbuds. So the issue becomes finding 1/8" Female TRS to 1/4" Male TRS adapters that aren't total junk. I tried a few different ones found here, and had extremely poor results from most of them. Most didn't make a secure positive mechanical or electrical connection. It's hard to imagine how they can even sell most of them! But again, this is NOT the fault of this little amplifier, it's just something to be aware of. I finally ordered some adapters from Parts Express (a seller who does sell here on Amazon), but I had to get them directly from that supplier since they didn't seem to have them available here on Amazon. I hope I can say that on here without it being censored or causing friction. Those adapters work perfectly. They fit tight and make solid electrical contact. With that problem taken care of, the unit does just what I need it to do, and the sound quality is plenty good for TV viewing. I'm not going to say that it's an audiophile-grade headphone amp, but it's really not bad at all. Having independent volume controls for up to four people is nice so everyone can use a setting that suits them. As I said, the main use for me is so either my wife or I can watch TV without disturbing the other person if they're sleeping or talking on the phone, etc. We just keep a couple pairs of headphones and this amp at our usual watching position, and it's very handy. I've seen complaints on here about buzzing or receiving AM radio broadcasts. I suspect that in all of these cases, the true culprits are either poor electrical contact when using crummy adapters or cables OR they've managed to allow the metal case of this unit to come into contact with something that's grounded (but not well) to another piece of their equipment, thus creating a "ground loop". Ideally, you will keep this unit's case electrically isolated from anything that might create a ground loop back to your audio source. With this amplifier and your headphones "floating" electrically from everything else, you will not likely get hum or buzz. And with good, solid electrical connections (avoiding poor adapters, etc), you will likely avoid any reception of strong AM radio signals in the area. All of this would be true of any amplifier. The sound quality is perfectly fine for an amp of this price range. It drives various headphones to levels far above anything I've needed. It seems to have fine frequency response and reasonably low distortion. The volume controls move smoothly and create no static. And I've been using it for a few years and had zero reliability issues. So I give the amplifier five stars for doing what it is supposed to do quite well.

Let me start with this amp is great. It is loud and clear. This is my first behringer product ever, I didn't like behringer before but this changed my mind on some of there products (not on there mixers, I'm am a Mackie freak!) We use this amplifier to power a pair a headphones for a drum monitor and it works well, we use a extension cable (25ft) to plug them in but I am worried it could clip because it needs to be loud. It's a shame them couldn't of put a clip light on each channel but the get very loud so it isn't too much of an issue. Power: When they say "4 powerful headphone amplifiers" they really mean POWERFUL!!! I was 3 yards from the headphones and it turned it up and I could hear it pretty good for being 3 yards away so thats powerful. When you are using them in a drum application you need a lot of power and this amp is perfect. I'm worried the headphones will blow!!!! Only problem is it dosen't have a power switch so you have to unplug it to turn it off but it dose have a power light. Sound: This amp will get very lout without causing any extra hum or his. It is very clear for being a behringer product. As it says it is stereo. Connections: This amp has 1/4 trs connecters for all connections (not standard 3.5mm headphone jack you would find on your iPod or computer) If your headphones have a 3.5mm jack (like on an iPod) you will need a 1/4 trs to 3.5mm adapter like this: 3.5mm Stereo Jack To 1/4" Stereo Plug (Black) You will need a 1/4 cable to connect it. If you are connecting it to a headphone port on a computer or iPod or something you will need another one of those adapter and a 3.5mm cable. There is many ways you could connect this. Plug it into a line-level source headphone-source One mistake I made was I only had a mono cable (only using the left side) so it only played in the left side. Make sure you have stereo adapters and cables (balanced) Overall: Pros: Powerful. Clear. Lightweight. Compact. Cons: No power switch. No clip light.

The amp is pretty good. I bought this because I'm getting sound out of my monitor and it just sounded a bit weak. I just bought a new pair of Audio Technica ATH-M50 headphones, which sounded amazing over the last pair I had. But the base wasn't quite loud enough for me when listening to EDM. This little baby is perfect for cranking the music up till my ears can't take any more! I can usually listen on setting 8 for about and hour or so before I have to turn it back down to a reasonable level again. But it's pure enjoyment. Like others have said, when you turn the volume up to 9 or 10 the sound tends to get a bit distorted. But there's plenty of space on the dial for enjoyment. Other comments have mentioned the portability factor of this is not great, which is probably true. It runs on AC power that needs to an outlet. For me this isn't an issue, it sits on my desk and has enough room on the power strip for it's own plug in. I can see how this could a major issue for someone that is on the move a lot, possibly a musician type. Its' pretty small so it doesn't take up too much space. It's only 4"L x 2.25"H x 1.25"D Since i have a pretty small desk space to work with this works out perfect for me. If you're not a mixing professional audio this thing works just great in my experience. If you do studio work you probably want something a bit more expensive. I also had to pick up some cables from monoprice to get from my monitor to the amp. Just plan ahead cause this thing takes 1/4" male plugs, so you'll need a converter if you don't have one. Most headphones come with one, mine did. The one I received is silver in color and not white like in the picture. After owning this product for sometime now. I would agree with others that there is a slight hiss or feedback when you have the volume on low. It's not noticeable at normal volumes though.

I returned my Pyle Pro PHA40 micro amp that was shooting sparks at me and decided to get this instead. I am very pleased. This little amp has some kick. You will need a 3.5mm female to 1/4 male adapter if you use standard 3.5mm headphones, but that's only a $5 purchase at your local guitar center. Also, you should know I have a pair of Koss Pro 4AA headphones that have a 250ohm impedance. This amp was MORE THAN ENOUGH to power my hi-fidelity cans. I cannot speak of how it would handle 600ohm headphones but it does 250 just fine. The volume goes way up. I was literally pained when I turned the volume all the way up. I do not recommend turning up to 11 just yet. You don't want to go deaf in the first week. So a nice bonus here is the fact you can have 4 separate headphones plugged in at 1 time with 4 separate volume controls for each pair. There is however only one input source available to you. Also, my major issue was that at maximum volume this amp does tend to distort a little. That however was using some pretty low quality audio (YouTube) and I have not yet tested with FLAC files. I can say that at normal human listening levels it sounds clear and loud. One more critique is that it has no on or off switch. Its a minor issue but it would be nice to just leave it plugged in all the time and flip it on and off at will. As its manufactured now the only on and off switch is disconnecting it from the included power supply. I definitely recommend this little amp if you just need that extra punch in your ears or if you need something to drive some higher quality cans. It was well worth the $25 bucks I paid and is really the cheapest amp option out there on the market.

I added the Behringer MICROAMP HA400 to my home studio setup and it's been a game-changer. The unit arrived on time and was well-packaged. It's incredibly compact, yet provides four channels which is perfect for my small recording sessions with friends. The sound quality is impressive considering its size and price point. Each channel has its own volume control which allows everyone to set their preferred levels. This is a feature we've found to be invaluable. Setting it up was a breeze. Just plugged in my stereo mix, connected the headphones, and we were good to go. The independent volume controls on each channel are very intuitive and easy to use, even for those who are not technically inclined. The construction seems solid and durable, which is important as it gets moved around quite a bit in my setup. I also appreciate the ultra-compact design which helps in keeping my workspace uncluttered. One minor downside I noticed is that when all four channels are being used simultaneously, there's a slight drop in volume. It's not a deal-breaker by any means, but something to be aware of. All in all, the Behringer MICROAMP HA400 is a cost-effective solution for anyone in need of a multi-headphone setup. It's straightforward to use, offers good sound quality, and is built to last. I would definitely recommend it to others looking for a reliable headphone amplifier without breaking the bank.

I have a computer where I have two headphones and a sound system attached, and I was wearing out my jacks switching between them. I though of just bringin in a mini-mixer from my setups, but it would take lots of precious desk space. I saw this thing, and knew it was the schnizzle the moment I saw it. It arrived today and after getting my setup in place, I am happy to report that it is pretty good for the price. It seems to have a negative effect on the bass, but just doing a little EQ from the software to boost the bass turned this into a 5 star device. The knobs are typical Behringer quality (read: high quality) and the cables lie nicely out the back. I bought some 3.5mm to 1/4" stereo jacks since all my stuff is 3.5mm but a nice 5 pack cleanly fixed this since you need 5 to fill all the slots. This unit is perfectly sized and looks sharp. The all metal case makes it look like it is ready to hit the road, and hit it hard while still looking good. The unit has a good weight, and the amplification is modest, with perhaps a little distortion after 3/4 throttle, like most mixers. For my Bose sound, I cranked my laptop to max and the speakers to half volume, and at 1/2 throttle it is very loud. I typically run it at 1.5/10 to 3/10. At 0/10 with the speakers at max, there is a little tiny bit of a hum which is there when disconnected from the amp, so this little mixer is very, very quiet. If you are like me and have two or more audio setups on your computer that you are constantly changing between or if you just want a knob to turn up or down, you need to get this unit along with the appropriate converters and you will not ever regret it.

I'm using this in a recording setup. I have two sources of input coming into the amp, one from a drum kit and the other from the laptop's headhone out. The drums first go to an Alesis 8-channel mixer. I use the Alesis monitor out and the laptop headphone out to first send to a 4-channel stereo mixer that combines the laptop audio and the drum mix into one stereo out to my Behringer HA400. (The Behringer only has the one stereo 1/4" input and even if there were two it would need input volume dials for me not to have to premix.) With this setup I can balance the drum mix and laptop mix to my liking in my headhones. This little amp does exactly what I needed it to do. It boosts the headphone signal from my laptop loud enough for me to hear the music over the ambient sound of my drums. I play with foam plugs under my headphones, because I have to play loud to get the tones I want for recording, and my hearing is already bad enough from playing drums. This is more an issue with the Alesis USB mixer(s) than my playing or the online medium I'm using. I use a second output on this amp to send a signal to my amp and studio speakers for playback, but this amp can send signals to four sets of headphones. The HA400 will pick up interference as a pretty loud buzz from the power charger on my laptop, but other than that one source of interference it puts out a clean signal. Solid build. Reliable. Nice headhone amp for price.

I was in need of a headphone splitter not just an amp but when I try to split the signal goes into mono and all the headphones I connect can only hear sound from one side of headphones. I managed to make it work during a podcast but I do not recommend this headphone amplifier as a splitter because of that. I will have to purchase another in future. I will deal with Mono for a few more months. The product itself isn't bad, feels sturdy and I have had no issues with loud buzzing and such as others. But I do have the issue of it feeding my MONO ONLY.

家に丁度、アンプのピンジャック出力から取れるコードがあったので入力に入れてみました。すごくいい音です。満足しています。

Der Behringer HA400 hat mich positiv überrascht. Ich nutze ihn zusammen mit meinen Beyerdynamic DT 770 Pro (80 Ohm) und der Kopfhörerverstärker liefert mehr als ausreichend Leistung. Die Lautstärke ist selbst bei leisen Audioquellen problemlos hoch genug und der Klang bleibt dabei sauber und unverfälscht. Die Verarbeitung ist für den Preis absolut in Ordnung und dank der vier getrennt regelbaren Ausgänge eignet sich der HA400 nicht nur für den Einzelbetrieb, sondern auch ideal zum gemeinsamen Musikhören oder für kleine Studioanwendungen. Für alle, die einen kompakten und preiswerten Kopfhörerverstärker suchen, ist der HA400 eine klare Empfehlung. Das Preis-Leistungs-Verhältnis ist wirklich hervorragend.

A seguire la recensione (spero esaustiva nonché utile) del Behringer MICROAMP HA400. TEST EFFETTUATI Da semplice appassionato di musica classica e lirica ho apprezzato la resa acustica sulle voci del Behringer (dal basso al soprano) mentre, tra tutti gli strumenti musicali, il pianoforte è quello che spicca di più, reso egregiamente con una sonorità ampia e vibrante che mi ha incantato. Giudizio leggermente negativo, invece, per l’AH400 riguardo le Sinfonie e qui mi spiego meglio con un esempio: nel Secondo movimento della Settima Sinfonia di Beethoven la partitura inizia “sommessa” (Allegretto) con pochi strumenti che il Behringer controlla, separa ed esalta con una chiarezza più che adeguata...poi però, man mano che gli altri strumenti iniziano ad aggiungersi all’ordito musicale, si va a perdere, almeno in parte, quella sensazione di precisione, separazione e definizione acustica che si aveva poco prima e questa sensazione va e viene seguendo i “pieni” e i “vuoti” della partitura; altro punto debole di questo mini-amplificatore sono le contrapposizioni serrate tipiche dei quartetti (violino/viola/violoncello) come, a titolo esemplificativo, nel D810 di Schubert - Quartetto n. 14 - D minor - Der Tod und das Mädchen – nella versione dell’Engegard Quartet; tutto ciò però penso non sia ascrivibile a un difetto dell’amplificatore e quindi non deve stupire quest’alternanza nella resa acustica poiché solo gli amplificatori di alto/altissimo livello (decisamente più costosi) suppongo riescano a separare con sufficiente chiarezza tutti gli strumenti musicali, specie i tanti presenti in un’orchestra. Ho anche testato le qualità dell’amplificatore attraverso svariate opere: dalla musica sacra al barocco sino all’Opera Lirica italiana...ed è qui, sulla lirica, che, a mio modesto quanto musicalmente incompetente parere, il Behringer dà il meglio di sé in particolare in tutte quelle situazioni in cui le sonorità di voci e strumenti risultano ben separate le une dalle altre o quando l’intensità della voce del tenore o del soprano domina incontrastata sulla musica sottostante...ed è proprio in questi frangenti - specie se teniamo contro del costo del prodotto – che la resa del Behringer appare sorprendente (un esempio: Giacomo Puccini – Manon Lescaut - Atto II – Oh, sarò la più bella – Soprano: Anna Moffo). Nota: chi è interessato, può trovare le composizioni elencate qui sopra (con i relativi interpreti) anche in formato video cercando su YT. ALTRE CONSIDERAZIONI Come già scritto da altri posso confermare che la qualità costruttiva è molta alta con potenziometri e connettori inscatolati in un telaio di metallo massiccio: raramente ho avuto modo di imbattermi in un prodotto consumer dal prezzo contenuto ma allo stesso tempo così robusto e curato nelle finiture. Aggiungo di non aver notato/percepito rumori di fondo od interferenze elettriche durante la riproduzione dei brani. L’amplificatore non scalda neppure dopo ore di utilizzo continuativo. TEST CONSUMI ELETTRICI - 1 cuffia - volume: 100% Se devo essere sincero, all’inizio (prima di comprare l’HA400) sono rimasto perplesso dalla mancanza di un interruttore ON/OFF sull’apparecchio...però poi mi sono detto: “Ma quanto potrà mai consumare questo scricciolo?”. E il test sul consumo elettrico mi ha dato ragione: attaccando all’amplificatore delle vecchie cuffie che, per ovvi motivi, non ho indossato durante la prova, non sono riuscito a determinare il consumo dell’AH400 (vedere foto allegata a questa mia recensione) neppure spingendo il potenziometro dell’amplificatore a fondo scala: ciò significa che il consumo è inferiore a 0,1 watt (utilizzando però, ripeto, un solo paio di cuffie e non delle casse acustiche le quali andrebbero a generare un carico elettrico rilevabile seppur presumibilmente minimo). CONCLUSIONI Pienamente soddisfatto. Consigliato senza riserve. E, per restare in zona Opera Lirica, un “Brava!” anche ad Amazon. N.B. Semmai in futuro si dovessero presentare dei malfunzionamenti/anomalie aggiornerò il prima possibile questa mia recensione.

Excellent
