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.

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。

Ho preso il Behringer HA400 per permettere a più musicisti di ascoltare lo stesso mix durante le registrazioni, e devo dire che fa esattamente ciò che promette: ha quattro uscite cuffie indipendenti, ognuna con controllo volume separato, quindi ognuno può regolare il livello come preferisce. È super compatto, costruito bene con componenti di qualità e anche a livelli di volume alti mantiene un suono pulito. Secondo molti utenti è una delle soluzioni più convenienti per un amp per cuffie a 4 canali. Punti di forza: · 4 uscite stereo indipendenti; · Controllo del volume per canale; · Alimentatore incluso (12 V); · Qualità audio buona per il prezzo. Qualche “ma”: · Alcuni segnalano rumore o distorsione se il potenziometro è troppo alzato; · Non ha piedini antiscivolo: su superfici lisce può muoversi facilmente; · Non è un amplificatore ad alta potenza per cuffie esigenti ad alta impedenza: va bene più per monitoring che per uso hi-fi. Perfetto per home studio, prove o registrazioni con più persone. Consigliato! ✅

Great little item. I needed it to boost the headphone out on my CD/DAB radio. Really improved output. Easily to set up and no noise. It's not what it was designed for really and so my set up can't be classed as HiFi but it's good enough for me.No distortion, easy to connect.
