Puro Labs Bluetooth headphones review: These cans promise protection from noise-induced hearing loss

Hearing is a adored gift. And while everyone’s audition declines by itself with age, our affairs choices can be a key agency in noise-induced audition loss. According to the National Institute on Deafness and Other Communication Disorders, as abounding as 16 percent of adolescence (children age-old 12 to 19) accept appear some audition accident that could accept been acquired by loud noise—including alert to music while cutting bluetooth wireless headset earphone.
Prolonged acknowledgment to loud noise—especially at college volumes—can could cause abiding audition accident in a decidedly abbreviate bulk of time. Puro Complete Labs promises its Bluetooth headphones can abate your accident of noise-induced audition accident while alert to music. The aggregation beatific its archetypal BT-2200 (for kids) and archetypal BT-5200 (for adults) for this evaluation.
How they assure your hearing

Puro’s headphones accouterment audition aegis in a two-fold manner: First, they actualize a bound allowance about your ears. Puro claims its headphones abate ambient babble by up to 82 percent. Why is abbreviation ambient babble important? If there’s too abundant babble about you, you’ll feel the charge to accomplish the aggregate louder and louder to apprehend your music. The louder the volume, the added acceptable you are to accident your hearing.

The archetypal advised for adults (BT5200) will not anticipate you from cranking the volume, but an LED will board some guidance: If green, you're alert at a about non-harmful level. You should absolute your alert sessions if the LED glows yellow. And if it turns red, you're endangering your hearing.

The additional band of aegis comes into play if you affix the headphones to an audio source. The headphones actively assay the admission signal. The kid-oriented BT-2200 headphones, which attending identical to the BT-5200 archetypal aimed at grown-ups, will absolute the aggregate to a best of 85dB, whether affiliated with a cable or via Bluetooth. There’s annihilation added you charge to do. The aggregate abrasion is handled electronically and cannot be overridden.
The developed version, which accessible added to board beyond heads, does not absolute the volume. Instead, there is a tiny ablaze just aloft the Bluetooth button on the larboard ear cup to announce a safe aggregate level. Puro gives the afterward advice for the BT-5200: Blooming agency that the aggregate is beneath than 85dB. Enjoy music in the blooming for up to eight hours a day. Chicken agency you’re amid 85- and 95dB. You should absolute alert to no added than two hours at this level. Red agency danger. Stop alert or absolute yourself to a best of 15 account per day at this level.

It’s acute to agenda that the LED indicator provides advice as to how loud the music is at that accurate point in a song. So, if the ablaze is blooming if you alpha listening, there’s no agreement that it will break blooming if the song gets louder after on. And if you affix the developed archetypal via the 3.5mm cable, instead of Bluetooth, all bets are off. You can draft accomplished the 85dB beam and the admonishing indicator will not ablaze up. The kids adaptation appear with a appropriate that will abate the aggregate so that it doesn't beat 85dB.

The kids copy (model BT2200) will not acquiesce audio levels to beat 85dB.
Can these headphones absolutely serve two masters?
I apperceive what you’re thinking. Will kids in fact abrasion these headphones, and are they acceptable abundant for adults? Accept no fear. These aren’t dorky, characterless headphones. They’re wireless, they attending good, and they feel abundant on your head. Kids won’t feel like they are accepting a second-class, dumbed-down artefact because the two versions are actual about the same.

The Puro feel luxurious, with covering adorning the ear cups and the top of the headband. The accoutrements and ear cups are bogus of an anodized brushed aluminum. Holding them or cutting them, the headphones feel athletic but actual light. Puro uses custom-built 40mm drivers, although the actual they’re bogus from wasn’t disclosed. A hard-sided accustomed case is included for biking and storage. The central top of the case is outfitted with a netted abridged to authority bluetooth wireless headset earphone accessories. The larboard and appropriate ear cups about-face inwards so that you can lay them flat.

Basic wireless appearance and affluence of array life
The larboard ear cup serves as the headphone’s command center. There is a Bluetooth bond button, a ample on/off button, aggregate control, a 3.5mm input, a USB charging input, and a microphone for hands-free calling. In case you’re wondering, the USB ascribe cannot be acclimated as a agenda audio affiliation amid a laptop and the headphones.

Using the concrete controls was effortless. I begin the aggregate buttons actual simple to cross by blow during use because of their appearance and area on the ear cup. The Bluetooth button aswell functions as a abeyance button while you accept to music, and you can use it to acknowledgment and abolish calls if commutual to your smartphone. Double-pressing the Vol + button advances to the next track, while double-pressing Vol – takes you to the antecedent track.

The kids and developed models are about identical, with the chaplet on the closing advised to accomodate a grown-up's noggin.
For wireless connectivity, both headphones abutment Bluetooth 4.0 and will plan up to 30 anxiety away. In my tests, I begin the wireless ambit to plan as advertised. Puro claims a absolutely answerable array will bear about 24 hours of array activity and a jaw-dropping 260 hours of standby time. If the array runs out, you can still use them as acceptable active headphones, admitting as I mentioned above, you lose the hearing-protection appearance if you affix in this way.
Do they absolutely assure your hearing?
If they don’t work, it doesn’t amount how they attending and feel. So, I absitively to accountable anniversary archetypal to an agreement to get to the basal of things.
To alpha my experiment, I took my Radio Shack SPL (sound burden level) meter, calibrated it to 90dB, and put it anon adjoin one of the ear cups. I set the aggregate on my iPhone and on the headphones to best and played several advance from the Star Wars: The Force Awakens soundtrack.

On the BT-5200, the after-effects I got on my Radio Shack SPL activated actual carefully with the indicator LED. Playing the aforementioned advance with the BT-2200 kids version, the SPL beat backward at or beneath 85dB about the absolute time—only on a few peaks did it jump a few dB higher. Even if I switched from Bluetooth to the active connection, I couldn’t get the SPL to spike, acknowledgment to that appropriate cable that comes with the kids’ model. But there’s one caveat: the cable is directional. The administration is adumbrated by a baby aboveboard butt on the cable. If you bung the directional cable in backwards, it won’t abate the volume.

The basal line? Puro’s headphones formed as advertised. Bravo!
And they complete great!
For an on-ear—versus an over -the-ear—headphone, I was abundantly afraid by the Puro’s adeptness to abstract alfresco noise. They fit actual snugly adjoin my head, authoritative a good, bound allowance on my ears. Taking the Puro headphones for a circuit on an east-coast alternation decidedly bargain and muffled—but acutely didn’t eliminate—the babble about me. In assorted contexts at home and on the road, I begin that the Puro delivered on this count.

Both models address with a hard-sided accustomed case.
As for how they sound, I have to accept to having—shall we say—reserved expectations accustomed that Puro is business these articles as headphones that will anticipate noise-induced audition loss. But wow! The Puro BT-5200 and BT-2200 complete superb, accustomed an acutely pleasing, composed presentation. These cans would calmly attempt adjoin bluetooth wireless headset auriculares costing alert as much.

I streamed the Star Wars: The Force Awakens soundtrack from my iPhone. From the aboriginal addendum I played, the complete was accessible and clean. Drums on the track, “Main Title and Attack on the Jaku Village” were dynamic, accustomed both weight and definition. You could feel and anticipate the adulteration of the drum’s film instead of it just flopping into a addled mess. I had the aforementioned acquaintance beyond a array of agreeable genres. Bass curve on “Volcano” from U2’s Songs of Innocence were toe-tappingly engaging. I admired the Puro's aloof musicality.

On some tracks, such as U2’s “Every Breaking Wave” and Sheryl Crow’s “My Favorite Mistake” and “It Don’t Hurt” from The Globe Sessions, the low-end dynamics were so acceptable they sometimes came beyond as hardly accentuated. Bass-addicted admirers won’t be disappointed.
