Headphones Can Be Great
Headphones have made a comeback — not true, they’ve never disappeared from use even as earbuds stole the spotlight. The advantage of a pair of headphones is obvious just by looking at them, because their size makes it possible to cover the ears and direct sound in a concetrated fashion. Plus they’re more comfortable than earbuds since they don’t “live” in the ear canal. But most important of all is that headphones, unlike earbuds, can have many times larger drivers (i.e., speakers) inside of them. This means a better frequency response to the audio being pumped into them and a much more enjoyable listenting experience. But there is a downside.
Loud Is Not Good
The downside is that it’s far too easy to turn up the volume and reap the kind of results that our parents warned us about when we went to loud rock concerts and stood up right by the huge speakers blasting out the sound — in other words, it hurt the ears then but worse caused greater ear damage (even significant) over time. The solution back then was to not be right up against the speakers, and it’s the same thing now — only it’s about keeping the fingers off turning up that volume control. Of course there is a difference between then and now, because there’s plenty of surface noise when you’re out and about with headphones on like traffic and crowds and other stuff that “forces” you to turn up the volumen. What’s needed is a pair of headphones that provides a quality sound response but also has built in safeguards against pushing up the volume. There is, and it’s from Puro Sound Labs who are known for making headphones that are designed to protect children from acquiing those bad volume levels. Only the difference here is that their PuroPro Hybrid Active Noise Cancelling Volume Limited Headphones (to be known as PuroPro moving forward) is designed for young aduits/adults who think they know better (but don’t), and so acts to protect them regardless of whether they’re listening on the street or in an office or at home.
What You See Is Just The Start
So let’s start with the box it comes in — because it’s not so dumb plain but kind of nice with hinges and all. Still it’s going to be opened and most likely forgotten about, although some will find it a good storage option. But taking PuroPro out of the box is going to happen, so it does. Notice that there’s no flashy LED lighting or huge emblems or signage screaming out at the world — no, these headphones are fairly large sized but not so as to be obtrusive. There’s no outward mic (it’s inside) or cabling dangling from them either — what you see is what you get to put on your head: being two leather protein ear cups utilizing memory foam for a comfortable fit and a headband connecting the two and enabling that fit to be adjusted as necessary. So you put them on and that’s that.
Of course there’s some weight involved, because there’s tech inside, like Bluetooth 5.0 which provides a more stable signal and better audio response than previous iterations of the radio tech. And a rechargable battery powering the whole business that, once charged, pushes upwards of 30+ hours (about 1/3rd less when some of the audio moderating tech is in action and about 300 hours if you just let them lye there). Don’t want to do the streaming but go old-school? Then plug in the included 3.5mm audio jack.
It's All About Sound
Now we’ve already noted that there’s an embedded mic for talking into — making the headphones telephone-like capable, so focus in on the drivers (i.e., the speakers) that are in each ear cup. Since the ear cups aren’t tiny, the drivers don’t need to be either. They’re not — 40mm dynamic are they and that’s a good size to be (compare that to those 7mm drivers in earbuds and that’s just funny). The response of the drivers is 20H - 20kHz and that makes for good listening, especially since attention was paid to having a balanced response curve and more attention than not paid to making sure bass response was right on. Saying Studio-Grade quality might be pushing it a bit out of the park, but the combination of audio engineering that went on certainly lives in that part of the neighborhood.
But what about the audio tech embedded inside? And which add 4 specialized mics? That’s for the active noise canceling section and why there’s not a puny battery working. Because the mics listen to the outside noise ( or ambient sound or environment audio garbage, call it what you will) and then generate their own sound to cancel out and return a sort of neutral calm. Of the two levels you can choose, level 2 is most geared for music and videos and such because it only pushes down about 15dB of that surface noise. But when the world needs to go away (audio speaking), then go for 32dB of hard noise reduction that is level 1.
Great Sound Can Also Mean Great Hearing Protection
The final hammer pounding in hurting the ears comes from volue limiting and which is in the name so it has to be there. The decibel (dB) level of audio can give out headaches like cheap thrills, so there’s the option of capping the sound at 85dB or 95. Organizations like OSHA and WHO say that 85dBis the maximum for safe listening — these orgs are run by adults who don’t care whether Blue Cheer is a rock band or laundry detergent — going on 8 hours before giving it up, while 95dB could rock a headache easy time but around 50 minutes or less should only cause a buzz of excitement (depending on what is being listened to).
So put them on and out you go or in you stay and sound is better controlled but even more so, better avoided from causing grief to your nervous system. Puro Sound Labs includes a semi-hard case worth carrying them around in, but why do that when it’s better to be listening with them on?
