The cleanest, loudest headphone amp I've ever heard! Drummers love this for recording as they can finally hear their drums through the headphones instead of over them!
Good pairing with Studio Live
Great product that accompanies any home or intermediate audio interface. Very Quiet amplifier with a basic design.
My only complaints are that the power supply feels a littles cheap, and that the knobs are numbered to 12, rather than a sensible 10.
Does the trick. There isn't much more to say. Get it!!
Good for the doe!
This little box has done fine for me... now don't get me wrong it is no Dangerous Music Box as recommended by my Rep Tony Dayton, but I didn't have the doe for the other one and this one so far has done nicely.
This was the missing element for my studio. It's a must have.
A Fine Headphone Amp
It easily does exactly what it is supposed to do and it does it well. Mine has driven 3 low-impedance headsets cleanly and PLENTY loud. I'm impressed. Get one...! Everything I have used from PreSonus has worked very well.
Perfect for the price
Huge, clean volume, easy setup, and it looks great!
The only problem I have with the HP4 is that it does not have an on/off switch. Not a big complaint but still something to consider.
I got my monitors and three sets of headphones coming out of this and its always been real reliable and quiet. Ive never owned a high end headphone amp so I dont know what to compare it to but it does what i need it to do...control my monitors and headphone levels with ease. Monitor mute button comes in handy a lot. Never used the mono button though lol....
Clean and powerful.
Simple, powerful amplification up to the task. I paid for clean headroom and rugged hardware and did not throw money at having e.q. and metering on a headphone amp. Perfect. Also, these units can be chained together for other rooms and users. In my opinion, this is a great unit at an excellent price.
Great headphone amp with great detail
I bought this unit a few weeks after buying a ART Headphone 4 for my home studio. This is a great headphone amp with some nice features. I use it with my AKG K701s; AKG 271 mk2s, and my 2 pair of Sony 7506's. The Sony's are getting less used these days now that I have the 271's.
4 features I like are the mono switch, the on/off switch in the power cord, the separate control for the pass-through for linking multiple units for more headphone outputs, and the 1/4" mono TS input jacks. Nice additions for the $129 price.
Sound wise the unit is a detail machine without being bright or harsh sounding. You will hear what is in your mix. Cables do matter, so experiment and choose wisely. The bass is very, slightly more extended and fuller than the ART Headphone 4, but I would expect so for twice the price.
You will not be disappointed with this unit at all. I'm very pleased.
Prefect piece of gear for a GREAT price. Best part is the SERIOUS amount of volume it can pump out! LOVE that it can control my monitors as well!
Great headphone amp
Very basic with just enough feature-wise to get by-- balanced ins and outs, monitor section, and mono button are very nice and quite useful. Great transparency and this amp is LOUD. With my interface at unity, I sit the pot at about 2-3 ticks up, of about 15 or 20. I love this thing. Pots do get scratchy, but this isn't the fault of the actual unit, it's a fact of working with audio.
good headphone amp!
purchased this headphone amp about 7 months ago. no problems, works as advertised! Thanks to my sales rep Bob mondock! yep!
The best part of this for me is the ability to have it on my desktop, and mute the monitor rather than having something more complicated set up in my DAW. The only con is that it only has 1/4 headphone jacks, would be great if it had both 1/4 and 1/8.
PreSonus HP4 Headphone Monitor
This is a pretty high-performance box, well worth the cost. Even if you crank the output to 11, it's still clear.
My only caveat would be that if you're using higher-impedance 'phones, you might want a little more power. I'm using some Beyerdynamic DT880 Pro 250 ohm headphones, and I'm left a little wanting for volume. On the other hand, my Sennheiser HD280 pros will tear my head off at much lower levels from this unit.
If you work with amps, this works well. Enough headroom for volume increase. I would buy this before buy some 30-50 dollar cheap amp. There is no on/off switch. I have mine in a studio that a strip breaker for a few other speakers and monitor are plugged into, then just use that as a master shut off..
A good offering with some minor drawbacks.
I use this at church for my IEM. It fit on my pedal board, That is a plus. The description is deceptive, as it only can handle two mono mixes, with two outputs each, or one stereo mix with four outputs. But all of the headphone amps are described that way. The sound is crystal clear. My only major complaint is the PLASTIC JACKS! Other than that. A great product.
Overall great box. Relatively clean channels. LOTS OF HEADPHONE VOLUME!!!
I like the mono function and that it has a "Monitor Section".
3+ year owner
I'm happy with mine....I read the other reviews of ppl having there's short out on them after a short period of time and must say im lucky...cuz Ive had this thing up n running throughout the whole stage of my recording career...its one of those backburner pieces that just never let u down....THANKS presonus... a great piece of my DAW setup.
I run 1 of the headphone outs into an RCA adapter that connects to a nearby stereo system AUX and thru some Bose bookshelves as reference for mixing. I also got a set of HD280's and Equation RP22xs plugged in..
Better than I expected
I purchased the HP4 in a pack with 4 AKG M80 headphones. The HP4 works well and sounds terrific..PLENTY of headroom. The 'mono' button allows you technically to send two separate mixes to the HP4..although I only use one. My only complaint would be the 'monitor level' knob. the ability to mute my monitors would be awesome, but i won't use this feature because the monitor feed isn't purely pass-thru. you can adjust the volume of the monitors from the HP4. I would have much rather had a passive monitor mute control..and perhaps used the additional amp for a 5th headphone channel. Nevertheless, it's still a great unit and a good buy.
do the job! use my AKG Q701 on these and its pretty good. not bad.
Find something else
I've used 2 different models of these: an older, and the revision. Neither has proved its worth. The plastic everything breaks down quickly, the jacks are now loose, and like another reviewer said, the volume levels aren't matched across each output. You can do better for your 130. To its defense, I picked them up for a small music conservatory and they get used pretty heavily, but it goes to show that they aren't built to last.
Not suitable for studio monitoring use
This unit is pretty good, but for a few problems that prevent me from using it as a serious monitoring controller.
1. The pots, like in some other Presonus gear I've used, are linear taper, not audio taper. This means that, past 1/4 turn or so, there is very little change in audio level (and massive change before that). This makes it very difficult to tweak the volume at moderate sound levels. I might mod the unit, replacing the linear pots with audio taper pots.
2. At lower volume levels, the two sides of the headphone are not at the same volume level. This could be due to the drive circuitry, or perhaps the pots weren't properly matched. This caused me some difficulty on a mobile live recording job, when I thought I had a problem with a microphone or preamp. It turned out to be the headphone amp.
3. The 51 ohm impedance won't properly drive some lower-impedance headphones, such as Audio Technica M50 (35 ohms), or basically any of the in-ear monitors that some drummers prefer to use in the studio (some of them as low as 14 ohms). The 63-ohm Sony 7506, of course, would drive fine. (Note: when your load impedance is lower than your drive impedance, it will all still work; but, you will get a gradual rolloff in the bass and your headphones will sound "thin".)
4. Due to a combination of problems 1 and 2, it's basically impossible to listen at a low or moderate sound level; if your goal is loud, and your headphones are 51 ohms or greater, this unit will work fine.
It's sound quality is actually quite good once you turn it up.
Not that great
First one I got was defective. There was no increase in volume after the 12-o’clock position. Second one worked. The salesman told me that this amp would be loud enough for a drummers headphone mix during recording. Not true and not even close. It does provide decent sound but my stereo amp that we still use for recording drums, sounds better and is louder. I would not recommend this for those who need the headphone mix loud, but at low to moderate levels this is probably as good as other brands in this price range.
Good when it worked, but didn't last long.
In less than a year, the outputs began shorting out. I could get it to work for a while by pulling out the output plugs and re-inserting several times. Then it just completely crapped out. I can't afford to buy new equipment every year, so I'll be looking for a different headphone amp.
Piece of junk!
Like many items "Made in China" it doesn't last. All the headphone volume knobs stopped working suddenly (1 week after warranty expired). No volume control and sound can be heard only on the right side. I took it apart to see what's up. All potentiometers are soldered to a board connected via a ribbon cable to the main board. There's no way to fix the pots except by changing the entire board. Not worth what it costs. Spend your money elsewhere.
its a nice little piece of equipment unfortunately it has started to sizzle when turning the voume knobs
