Amazon Prime Day is right here! Prime members ought to click on via to Amazon to see members-only offers. The costs proven listed below are the most effective obtainable to all.

Puro Sound Labs isn’t a family title on the planet of headphones simply but. Certainly, on the corporate’s personal web site it’s described as a “small household run enterprise”. The prospect of competing with the likes of Sony, Bose and even Apple within the aggressive private audio market is an intimidating prospect, however Puro goes about issues its personal approach.

The PuroPro appear like customary wi-fi headphones with ANC, however they’ve a novel promoting level – quantity limiting expertise.

To be able to defend your long-term listening to, these cans max out at 85dB by default. There may be an choice to bump this as much as 95dB, however that’s solely really helpful for as much as 50 minutes of listening time. However do you really want headphones that average the quantity for you, and the way properly does the remainder of the expertise stand as much as the competitors? Learn our full evaluation to search out out.


The PuroPro headphones have a glossy, minimalist design that’s nearly utterly freed from branding. The black mannequin I examined is the one color choice obtainable, however I’m an enormous fan of how these cans appear and feel.

My head is on the big aspect, so I typically wrestle with over-ear headphones digging in across the crown, however the smooth padding right here meant that wasn’t a difficulty. The adjustable strap additionally has a helpful numerical scale, so I used to be in a position to set it to 20 every time and know I used to be getting a great match.

The cups themselves are among the many most snug I’ve tried, and earlier than lengthy I forgot I used to be even sporting. The letters ‘L’ and ‘R’ are emblazoned on the insides, leaving you in little question about which approach spherical to make use of them.

The headphones felt very safe when sitting down or strolling, though wobble significantly whereas operating so I wouldn’t suggest them for understanding. There’s additionally no sweat-proofing, so these are a greater choice for work or travelling as an alternative.

There are additionally few bodily controls, with only a handful of buttons to do the fundamentals. The ability button can be utilized to play/pause tracks and set off the digital assistant, whereas the quantity rocker may skip tracks and set off the 95dB mode.

Moreover, the headphones go into pairing mode and offer you an thought of how a lot battery you’ve got left (excessive/low) every time you flip them on. Contact controls would have suited the minimalist design, however maybe that’s one thing for future releases.

Disappointingly, the PuroPro headphones cost by way of micro-USB and never industry-standard USB-C, though I didn’t discover myself having to plug them in fairly often. Whereas they’re meant for use wirelessly, there may be additionally a 3.5mm headphone jack for wired connections.

The headphones fold down into a comparatively compact hard-shell case, which in flip got here inside a horny picket field. Prime marks for sustainability right here, and the field has quite a lot of different potential makes use of.


Earlier than speaking about how good these headphones sound, let’s give attention to their key function. 85dB is the utmost quantity that the WHO and different trusted organisations all over the world suggest with the intention to forestall everlasting listening to injury. That is thought to permit as much as eight hours of secure listening time, whereas leaping as much as 95dB implies that plummets to simply 50 minutes.

Puro Sound Labs has been producing quantity limiting headphones for youngsters for just a few years, however PuroPro are the primary cans designed for adults. Their most quantity is ready to 85dB by default, though you possibly can maintain down the center of the quantity button for just a few seconds to bump it as much as 95dB.

It did really feel fairly thrilling to listen to the massive soar in quantity, but it surely’s value saying that 95dB might be too loud for most individuals. They key query right here is whether or not you possibly can belief your self to maintain the quantity at a secure stage, notably with some headphones maxing out at greater than 100dB. For me, figuring out that I may pay attention for hours and never injury my listening to was extraordinarily reassuring.

Puro says that the 40mm drivers on the headphones present ‘studio grade audio high quality’. Whereas I can’t touch upon that particular declare, I’ll say that I used to be extraordinarily impressed by the sound high quality they produced.

To be able to successfully check them, I used Amazon Music’s ‘Extremely HD’ service. 5 million songs on the platform can be found at a bitrate of as much as 3730 Kbps, whereas Amazon’s full library of 60 million+ songs is obtainable at one thing near 850 Kbps.

The atmospheric intro of ‘Blinding Lights’ by The Weeknd sounded unimaginable, and the constant heavy beats all through the track sounded simply nearly as good.

Regardless of being a particularly totally different fashion, listening to Tones and I’s ‘Dance Monkey’ was additionally extraordinarily fulfilling expertise. The extra digital fashion backing actually labored to the headphones’ benefit.

Nonetheless, on songs with much less background manufacturing, it’s not fairly as spectacular. ‘Aint No Sunshine’ doesn’t sound dangerous per se, however Invoice Withers’ vocals aren’t captured as precisely as I hoped. It’s not so simple as trendy songs sounding nice and older classics being underwhelming although.

Prince’s Signal O’ The Occasions was remastered in 2020 and I couldn’t assist however groove alongside to the bass guitar riff within the background. The headphones had been in a position to make listening to this track really feel like an expertise, which is spectacular on cans at this worth level. The identical may be mentioned of ‘Is that this Love’ by Bob Marley, and I used to be in a position to select particulars within the track that weren’t clear when utilizing different cans.

Conversely, Bruno Mars’ Grenade sounded a bit muddy, the mix of backing sounds not fairly coming via an successfully as I’ve heard on different audio units.

Vocals are spectacular throughout the board, providing glorious readability and wealthy audio. After all, that is depending on the microphone that individuals are utilizing to document it, however the podcasts that made the lower on Amazon Music definitely sounded glorious.

There are 5 microphones in whole on the PuroPro headphones, though 4 of those are used for the energetic noise cancellation. This has two modes, which you’ll cycle between by urgent a button on the fitting earcup – ‘ANC 1’ supplies a ‘deep’ noise discount of 32dB, whereas ‘ANC 2’ is claimed to supply a extra ‘common’ noise discount of 22dB.

I most well-liked the latter, though I tended to make use of the headphones in conditions the place I didn’t wish to block out completely all of the background noise. The very best setting is fairly efficient at this, however nonetheless falls a way wanting the expertise you’ll discover on flagship headphones such because the Sony WH-1000XM4s. You’ll pay much more for the privilege, although.

Having only a single microphone for audio enter means the standard suffers, and might sound a bit of muddy or distorted in conditions with background noise. It’s high-quality for calls, however I’d suggest alternate options or getting a separate mic for something extra critical. After all, this may be improved by utilizing the cable within the field to create a wired connection.

I used the Puro Professional headphones each wired and wirelessly when recording Quick Cost, Tech Advisor’s weekly video podcast. First up, right here’s what they gave the impression of when connecting by way of Bluetooth:

For comparability, right here’s what the wired connection was like:

Whereas it’s simple to criticise some areas of the PuroPro’s efficiency, we’ve to keep in mind that the basics of sound high quality are actually glorious.

Battery life

On its web site, Puro claims that the 750mAh battery within the PuroPro will get you 28 hours of playtime with ANC on, and 32 with it turned off. That’s greater than you possibly can anticipate from most headphones at this worth level, and can guarantee you possibly can pay attention for a number of days with out worrying about them operating out of juice.

You’ll know when you’ll want to cost them, too – the PuroPro headphones let you know whether or not battery is ‘excessive’, ‘center’ or ‘low’ every time you flip them on. Sadly, you’ll need to make do with the micro USB port, however I wasn’t ready lengthy earlier than the headphones had been prepared for one more listening session.

Worth and worth for cash

The PuroPro headphones can be found direct from Puro Sound Labs for $199.99 within the US. Nonetheless, within the UK we’d suggest heading to Amazon, the place they’re presently on sale for £189.99.

That undercuts lots of the entries in our greatest noise cancelling headphones chart, coming in at below half the worth of the likes of the Bose QC 35 II and Sony WH-1000MX4.

Whereas there’s a noticeable efficiency hole to these flagship cans, I actually don’t assume you’ll be upset when you decide up the PuroPro.


Quantity limiting expertise apart, the PuroPro are a really achieved pair of noise cancelling wi-fi headphones.

Their glossy, minimalist design exudes class, whereas the smooth padded earcups and headband means I may comfortably pay attention for hours on finish. That’s one thing I used to be tempted to do, with these cans providing actually glorious sound high quality throughout a number of genres of music and vocals. The ANC itself isn’t excellent, and the bodily controls could be a bit clunky, however there’s actually not a lot to dislike right here.

Being restricted to 85dB sounds irritating on paper, however in actuality that’s lots loud sufficient for most individuals. There’s loads of science to recommend that’s a wholesome higher restrict, and you’ll nonetheless bump issues as much as 95dB if you’d like some additional oomph.
