Puro Sound Labs PuroPro ANC wireless headphone review

| |

I’ve lengthy advocated for safeguarding your listening to by limiting the degrees you hearken to. Lengthy-term publicity to excessive sound strain ranges results in noise-induced listening to loss (NIHL), which may tremendously scale back your sensitivity to excessive frequencies and midrange frequencies which can be elementary to understanding speech. One other potential symptom is the fixed annoyance of tinnitus (aka ringing within the ears), which may develop into everlasting—and there’s no treatment.

Puro Sound Labs addressed this concern with its PuroQuiet headphone, reviewed right here, which is designed for kids and limits its output stage to guard them from NIHL. Now, the corporate has launched an grownup model of the identical concept. The PuroPro purports to restrict the sound strain stage reaching your ears whereas offering hybrid lively noise cancellation, Bluetooth connection to your supply machine, and glorious sound high quality. It’s remarkably profitable in reaching these targets, with one minor caveat.

This overview is a part of TechHive’s protection of the very best headphones, the place you’ll discover opinions of competing merchandise, plus a purchaser’s information to the options it’s best to contemplate when searching for any such product.

Options

The PuroPro is a light-weight, over-ear headphone made largely of plastic with protein-leather-clad earpads and adjustable headband. The earcups fold right into a compact kind that matches within the included journey case.

The PuroPro folds right into a compact form that matches within the small included carrying case.

Apparently, the PuroPro is shipped in a wooden field. The wooden could be very gentle; it jogs my memory of the balsa wooden used within the mannequin airplanes I used to construct as a child. The corporate touts its “environmentally pleasant packaging,” however I’m undecided how environmentally pleasant this wooden is in contrast with cardboard.

Every earcup homes a 40mm full-range, custom-designed dynamic driver with a frequency response specified to increase from 20Hz to 20kHz with lower than 1% THD. The rated energy delivered to the drivers is 10mW, and the wired connection has an enter impedance of 32 ohms. The corporate touts its Puro Balanced Response Curve, which is alleged to ship clear, crisp vocals and full, dynamic bass inside the quantity restrict imposed by the headphone.

Talking of which, the PuroPro limits the sound strain stage of its output to assist keep away from—or a minimum of scale back—noise-induced listening to loss. Not like the PuroQuiet, you possibly can choose one among two limits: 85 or 95 dB SPL. The Occupational Security and Well being Administration (OSHA) specifies that staff may be uncovered to a mean of 85 dB SPL throughout an eight-hour day, whereas 95 dB SPL is secure for under 50 minutes. I assume Puro Sound Labs figured that adults may be accountable for time-limiting their publicity at 95 dB SPL, however I believe that loads of younger adults is not going to heed that restrict.

As with many wi-fi headphones, the PuroPro gives hybrid lively noise cancellation (ANC) with 4 microphones (two per earcup) that decide up ambient sounds. The headphone’s DSP inverts the part of these sounds and provides that sign to the unique sounds, decreasing the general stage due to part cancellation. Apparently, the PuroPro gives two ranges of ANC: 32 and 15 dB. The phrase “hybrid” refers back to the passive attenuation provided by the circumaural earcups.

The PuroPro has a number of cool options.

Bluetooth 5.0 offers a wi-fi connection. The precise earcup offers a 3.5mm analog audio connector for legacy gadgets, and the headphones include a cable to attach them. Fortuitously, the headphone doesn’t want the facility to be on for any such connection.
