PreSonus HD9 Professional Monitoring Headphones — High-Power Handling, Closed-Back, Circumaural Acoustic Design Studio Recording Headphones for Professional Mixing and Monitoring

Worth the price, great for tracking
For the price, it’s a great set of headphones. I use them in the studio all the time. Nice long cable for studio work, too long for a pair of street headphones, but that’s not why I got them. Good range of sound, respectable bass, big but very comfortable. Pretty sturdy, I’ve used them for several months and there’s not much wear and tear. Not quite high quality enough for mixing (to be expected at this price) but I use them all the time for studio monitors and engineering. Bang for the buck, they’re totally worth it.

Excellent Sound quality/clarity with a very flat response. A little flimsy feeling though…
I got these on sale for thirty bucks. For that price you can’t go wrong, I don’t care who you are or what material you listen to. Upon opening the box you will notice they are well packaged and as soon as soon as I pulled them out of the box, light weight and flimsy are the first two things that came to mind. I have somewhat big ears and they completely enclose and seal my ears with room to spare, however they are in no way too big. They feel very comfortable, partly do to the light weight. After a very long three hour session they did begin to feel slightly uncomfortable due to the clamping force. They can be flexed by hand in a way to make them squeeze a little less and that did help. As for the sound quality, fantastic! I use these for mixing when I want to hear my mix on something else to compare to my monitors or if I’m doing some late night mixing and need to keep the noise down. They have a very flat response and can take everything I throw at them. I produce/mix mostly electronic music, Dubstep, DnB, etc… and if I low-shelf these ~+2.5db @ 150Hz then I get an extremely accurate representation of what I’m going to hear in my car for example. At the normal selling price of around sixty bucks I might just go ahead and spend another forty to get Sennheiser HD380 instead. What I don’t like about these is that the cable is not replaceable (-1 Star). For the price I paid, it’s really a non-issue, but as I mentioned if they would have been their regular selling price, I probably would have spent a little more for the HD380’s which are sealed (these are semi open) and also have a replaceable cable. One last thing to mention regarding the semi-open design is that I expected to hear quite a bit more ambient noise and it wasn’t the case. Besides, once the music is going ambient is not even an issue. Hope this helps someone else considering these.Update: They really don’t block out as much ambient noise as I had originally stated. After using these in more situations, I have to retract that from my original review.

Depends on user intentions
***update***The HD9 cans are not closed back. This is probably why they sound really good but leak like crazy. Why in the world did nobody not mention this? This thing has seven or eight holes out the back on the cans. They are the size and style of what you would see if you removed the pads. They holes are on the top and hard to see, you have to flip the cup and look at the “seam” part.I’m still on the fence about these cans, but you should consider these semi-open. I’m going to have to modify these guys so I can use them for vocal tracking.See original review below, the leakage was noticable immediately.***original review***These sound good enough. That’s pretty subjective anyway. I would say they’re flat adjacent. And they’re more comfortable than a whole host of studio headphones which seem to never want to stay on my head, or pinch everything around the ears. My head size is snapback hat size 4 snapped in, 3 unsnapped.Now to to iffy stuff.These aren’t noise cancelling at all. Obviously these aren’t active noise cancelling but you will hear sounds if someone is in the same room as you. What I mean is that I can’t zone out and ignore whatever is going on without turning the volume up to the uncomfortable zone.On to the thigh test. Yes it’s a thing, look it up. These leak. I can’t possibly believe that a condenser microphone wouldn’t pick up the leaking sound from these if one were to use it for that purpose.Pros: Look nice, sound nice, fit/feel really nice.Cons: Non-replaceable cable, super annoyingly long non-replaceable cable, leakage both ways.I may or may not keep these. It’s one of those, “not all that bad, not all that great” type of products for me.

Maravilhoso, lindo, boa construção, ótimo som e nenhum ruído…Pra referencia é bacana apesar de não ser o mais indicado, pra DJ sem duvidas é o correto e indico de olho fechado, vem com adaptador e p2 banhados a ouro e além disso o adaptador p10 é roscado, articulaçao ideal e uma bag estilosa!

Un produit qui répond parfaitement à mes attentes.
