ARTHeadAMP4 Eight Output Stereo Headphone Amplifier

I rarely write reviews for Amazon, unless I find a product that is truly worthy of mention (good or bad). I am somewhat of an audiophile. I take my music very seriously and I am VERY picky about sound. Until recently, I was using a portable headphone amp made by Fiio (which I will continue to use with my iPod while on the road). I wanted a good amp that could hook into my Denon 165 watt receiver, that would deliver great sound and would drive my phones well. I did my research and chose this ART HeadAmp4.Quite honestly folks, this amp has been such a great improvement, that I don't know how I got by without it before. This amp is the real deal. It amplifies your headphones in a way that improves the sound stage so much, you will be very pleasantly surprised.I have about twenty pairs of headphones. Some of them have been more difficult to drive than others, and my receiver alone was not giving them the boost needed to get the most out of them. This is no longer an issue. I am now getting so much more out of my headphones....from bass to mids, to overall sound stage........the difference is amazing. My wife is not nearly as critical as I am when it comes to sound. I had her listen to some songs utilizing just my receiver, and then switching to the amp. She was floored at the difference in sound. It's just so much more lush and warm, with the use of the ART.The amp is well constructed; a good portion of it is metal. It allows for the use of eight headphones, and it can easily drive them all at once.........trust me.....I have already tried it. There are eight inputs on the rear of the unit....four small and four standard size inputs. The four knobs on the front of this unit allow you to adjust the amount of amplification on each of the four channels.I keep my knobs at around 5........I don't want to blow my head off, or damage my ears, by moving it much past that level. Others may want more amplification, but this setting is perfect for me. Setup is super simple on this ART unit. Plug the amp into the electrical outlet, and run a decent patch cord from your headphone jack on your receiver, to the input port on the back of the ART. Violla!!!!.........you are ready to listen. Again, I cannot emphasize enough what a difference you will encounter.I listen to several genres of music. My primary choices are some alternative music, blues and blues/rock, downtempo/chillout music, and classical (with emphasis on chamber music). The ART HeadAmp4 wonderfully enhances all of these genres,and I am sure that it is fabulous with others as well. My equipment is a Denon 165 watt receiver, a Polk Audio subwoofer, and two Sony tower speakers. My audio equipment is very good, but certainly not the best. Whatever type of equipment you have, you will benefit from this headphone amp.I do not work for ART or any other electronic entity. I am just a guy who has been enjoying music for over forty years and using headphones since I was 15 years old ( I'm 57 now). I wrote this review, because I wanted to help answer any doubts that some prospective buyers might have. I am sure that you can find better amps if you spend more money. But for just around 60 dollars, this ART unit is a true gem. Honestly.Thanks for checking out my review, and I wish you good listening.

While this item is marketed mostly to musicians, I bought it as a headphone amplifier/splitter for my TV. Cheaper battery-powered headphone amps are available, but the specs and features of the ART HeadAmp4 made the difference for me, the higher price notwithstanding.There are four separate outputs (and four separate volume controls), making the amp a splitter as well. It's powered by a small wall transformer instead of batteries. The case is extruded aluminum, not plastic, and it has rubber feet that won't scratch furniture.Sound is very clear and there is plenty of amplification for any type of headphone.The amplifier will work with any headphone level output. That is, you could use it with any computer, video game, TV, radio, MP3 player or other device with a headphone jack.You do need a cable with a 1/8" (3.5mm) male stereo plug on each end. This is not supplied with the amp, but is available from Amazon or other vendors.My only minor gripe is that there is no power switch, so you have to unplug the wall transformer to turn it off. I plugged the wall transformer into a small switched plug strip which works fine but does add yet another cord to our increasingly tangled TV/audio setup.Overall, we're very pleased with this high quality unit.Update: A few months after we bought this amp, one channel died. Didn't bother to return it as we use only one channel at a time.About a year after purchasing this unit, we bought another for a different location. We really like 'em, as you can see.

Quiet, compact, solid build quality, easy to set up and reliable. I'm a musician/audio engineer. With the right variety of quality cables, I can cover pretty much any monitoring situation, from rehearsal to recording to mixing. It has a nice smooth range, topping out at about +6 db over line level, with a clear/flat sound. This has served me very well, fits easily in my laptop bag. Aside from some potential for the odd "lemon off the line" unit as with anything else I suppose, some of the lower ratings/complaints here seem related to components down or up stream more than anything. Personally, I've been at this for a long time...plagued by lower quality cables, connectors, headphones, inputs/outputs, adapters (the worst), splitters, audio cards, etc. Especially 1/8 Inch, sadly everybody loves earbuds. In fact I can't say how many times someone has brought something or another to a session to discover they have an issue when it seemed just fine at home and I've had to provide a replacement. What is it that makes us want to doubt new components over the old junk we've been toting around for years? Sentimental value on random accessories and cables is definitely something to lose in a hurry. There are many possible weak links in an audio chain...this unit certainly does not appear to be one of them. Be sure to check them all before you go tossing perfectly good units out the window or into a return box...when what you should really be tossing in the trash is that dusty kinked radio shack 1/8" flaky splitter cable behind your PC under your desk that you taped tension to one side so it does not cut out in the left ear...all of which you forgot was in front of this unit or another.

I'm so glad I bought this at the right time and at right price ☺️ , this cost me around 4k.This amp is total worth the price for simultaneous earphones or headphones testing. I connected this to my DAC and source. No hiss in the output. Clean sound.Well a value for money product. Thanks to the seller 🤘

Molto buona la qualità audio e interessante la presenza di due tipi di ingresso Jack evitando adattatori.

supports both 6.35 mm and 3.5 mm inputs/outputs, has stereo signal out, and easy to use. got it, plugged it into my mac mini and started using it right away. exactly what I need!

I use it in conjunction with an ART SplitMix 4 to combine the output of 2 laptops and a computer at my desk and output it all to both my speakers and headphones. Works very very well. I'm not an audiophile, but for me, the sound is very good, and more importantly, I no longer need to plug things in and out and can adjust the sound levels from the different sources easily. I used the Splitmix on its own for a few years, and while that worked ok, the SplitMix is passive powered so the output was quite quiet. Now boosted with the ART amp I can again "accidentally" piss off the neighbours when I need to.

Petit produit, plutôt bien fini.Assez lourd pour sa taille, parfait pour qu'il reste en place.Parfaitement isolé, le son est très correct.Utilisé en studio pour partager les retours casques avec volumes indépendants.Le + : Vous pouvez raccorder du jack 6.35mm ou 3.5mm sans adaptateurs et ça c'est vraiment bien pensé.Le - : Peut être un petit peu cher.
