Laifen P3 Pro electric shaver: two-minute review

The Laifen P3 Pro is positioned as a compact electric shaver perfect for travel, and it's immediately reminiscent of the Panasonic Swipe Right we reviewed last year: a small, blocky design with a three-slot shaver head, waterproofing, and USB-C charging.

It's almost suspiciously similar to the Swipe Right, in fact, though it feels a bit more premium. The body is constructed of precision-machined aluminum and comes in either the default alloy or 'space gray' colorways, with a small window on the front that shows the motor at work. Both the transparent top cover and the shaver head attach magnetically with a satisfying snap, and the charging port is concealed seamlessly in the base with a small lid. It's almost as if Apple designed an electric shaver.

Unlike Panasonic's effort, though, the P3 Pro eschews any fancy touch technology for the ol' reliable: a simple button. Hold to turn it on and off, and click to activate the shaver once it's turned on. Easy as pie, and instantly fixes one of our biggest issues with the Swipe Right — nobody needs finicky touch controls for something as simple as a travel razor.

However, like many compact shavers, the P3 Pro is ill-suited for anyone with a large beard. The lack of a trimmer head or any other special attachments (which feels like a significant omission, considering how easy it is to remove the standard shaver head) means that while trimming a beard is technically possible, it's a slow and ineffective process. For stubble, though, it absolutely blasts through and provides an impressively smooth finish for a dry shave.

The only other downside here is the price. I'll dig into it further down in this review, but needless to say, Laifen has unfortunately followed Apple in pricing as well as design ethos. This is a damn expensive product, though I have to concede that the premium design and performance do justify the asking price.

In short, I fully expect to see our esteemed editors put the Laifen P3 Pro in the 'best travel' slot of TechRadar's best beard trimmer and electric shaver roundup, and will be having some stern words with the Home Tech team if it doesn't make an appearance somewhere in that list.

Laifen P3 Pro electric shaver: price & availability

• List price: $179.99 / AU$249.95 (about £173)
• Launched: September 2025
• Availability: US, Canada, Australia, and Europe (UK import only)

The Laifen P3 Pro originally launched in late 2025, and is available directly from Laifen in the continental US, Canada, Europe, and Australia. UK shoppers do get free EU shipping, but you'll have to buy in Euros as Laifen only maintains a generic European site, not a UK-specific one.

Pricing varies somewhat between regions. In the US, it's a steep $179.99, and the EU price of €199.99 converts to an even more expensive £173.34 at the time of writing, while the Australian price of $249.95 is a little more affordable after conversion and US sales tax.

It's undeniably quite a lot of money for an electric travel shaver — even a very high-quality one like this. Nonetheless, I don't want to knock it down too much for this; it really does feel like a high-end product that's built to last, and if you've got the dough, it's a worthy purchase.

Laifen P3 Pro electric shaver review: design

• Very compact and sturdy design
• Waterproof and easy to clean
• Parts attach magnetically

Aside from the (mildly pointless) visual flair of the motor window, the P3 Pro has a pretty straightforward design. It's very compact, small enough to easily fit in the palm of your hand, meaning it can be carried in a bag or even a pocket. The cap that protects the blades attaches magnetically and doesn't seem to be at any risk of falling off in transit.

The shape is perhaps not quite as ergonomic as some of the best electric shavers (which are commonly shaped to fit into your grip), but this is ultimately just a byproduct of how small the P3 Pro is. When using it, I found it fitted comfortably in my hand; granted, my hands are quite large, but I think you'd need extremely tiny palms to struggle here.

The aluminum casing makes it a little weightier than some competitors, but I didn't find that to be a problem, and the brushed metal finish offers sufficient grip even with damp hands. The entire unit feels very durable and well-constructed.

Underneath the glass motor window is a pair of LED icons that indicate whether the razor is turned on or set to 'flight mode' (meaning that it won't activate unless you hold down the button). The single control button is responsive and has a nice, satisfying click to it.

With an IPX7 waterproof rating, the P3 Pro is technically safe to be completely submerged in up to one meter of water for up to 30 minutes. I can't see any rational scenario where that would be necessary, but the point is that you can safely use it in wet environments; no need to worry about moisture damaging it.

Once the USB-C port is sealed with the attached tab, you can simply remove the triple-blade head and wash both parts under running water (though it should be noted that you'll need razor oil to re-lubricate the blades if you wash them with soap or other cleaning products, and this isn't included). I found washing it to be remarkably easy after use, and simply rinsing it thoroughly without soap was perfectly sufficient after a regular shave.

(Image credit: Future)

It's genuinely really difficult to find a single design flaw here, really. As I mentioned earlier, the magnetic blade head lends itself to swappable units, and a proper beard trimmer attachment would've been a very welcome addition here, but overall, the P3 Pro is exceedingly well-designed for its intended purpose.

I would maybe note that it could benefit from having slightly more in the box. I won't mark Laifen down for the lack of attachments (after all, this is supposed to be a super-compact travel shaver), but it would've been nice to see a small brush or some blade oil included here. The charging cable is also only USB-C to USB-C, meaning you'll need an adapter if you want to charge it from a regular wall outlet. In truth, though, this is mostly nitpicking on my part; I honestly really love the design of the P3 Pro, and it really feels like a premium device in the hand.

Laifen P3 Pro electric shaver: performance

• Gentle even on thicker stubble, but won't work on full beards
• Wide-angled head provides a nice close shave
• Where does the hair go??

OK, I'll be completely honest here: I have a full beard, and the Laifen P3 Pro is simply not designed to deal with that. I did find that it was ideal for eradicating stubble on my neck and cheeks, and it was at least somewhat capable of tidying up the edges of my beard, but the latter was a slow process and lacked the precision of a proper beard trimmer. Nonetheless, I was pretty cautious; I get the feeling this thing could've happily cleared off my whole beard if I actually went straight for the skin.

With that knowledge in hand, I enlisted the help of my father, who maintains a clean-shaven look but has been known to let it get a bit scratchy. His report was glowing; week-old stubble came off swiftly and with virtually no irritation, resulting in a shave as close as you'd expect to get from a larger electric shaver.

(Image credit: Future)

It's not particularly noisy (it was far quieter than the cheap old Philips B1216 trimmer I usually use for beard care), and the dual 12,000RPM motors do a great job of cleaving through thicker stubble. The head has a wide-angle foil design - similar to the Panasonic Swipe Right I mentioned earlier in this review - that helps cover more skin and provides a closer shave.

Although Laifen officially designates the P3 Pro for face and neck use, that flatter head design means you could feasibly also use it for other parts of the body, too - provided the hair you're dealing with isn't too thick. I didn't deign to shave my armpits or legs during my testing period (I don't need to be more aerodynamic, sorry), but I reckon a lot of users would be able to use it for this if so inclined.

(Image credit: Future)

The battery life is reported at an impressive 100 minutes, and I tested this by turning it on from a full charge and leaving it running with a stopwatch. Yes, this was a fairly annoying process — it's quieter than some electric razors, but it's certainly not silent — but I'm pleased to report that it ran dry at just shy of 93 minutes, which I'd say is close enough considering that a daily once-over takes barely a minute or two. It's certainly longer than some bulkier competitors can muster, which is stellar performance for such a small device.

It holds its charge remarkably well when not in use, too. I actually received this shaver more than two months ago and didn't have a chance to review it immediately, yet it was still at near-full charge when I finally unboxed it. The USB-C cable offers fast-charging, which can get you about eight minutes of shaving from just three minutes plugged in. If it's completely drained, you'll get a full charge in around 45 minutes.

Buy it if...

You want a travel razor
If you want to maintain a clean shave on the go and prefer to travel light, this is probably the single best option on the market.

You want an easy clean shave
If you're aiming to maintain a nice close shave with minimal fuss, the P3 Pro is ideal - it delivers a clean finish with easy cleaning.

You like to shave in the shower
With IPX7 waterproofing, you can use the P3 Pro in the shower without fear of it getting damaged or waterlogged.

Don't buy it if...

You're maintaining a beard
Without any extra attachments for precision trimming, the P3 Pro just isn't well-suited for anyone who wants to look after a full beard.

You're on a budget
Although it's an extremely premium-feeling product, there's no denying that the price tag will place this shaver out of reach for some potential customers.

Laifen P3 Pro: also consider

Panasonic Swipe Right
Probably to closest product on the market to the P3 Pro and notably a lot cheaper (but only in the US, for some reason), the Swipe Right from Panasonic is a similarly ultra-compact travel shaver that won't suit bearded users but delivers a nice close shave on the go if you prefer the clean-shaven look.

Braun Series 9 Pro
We called the Braun Series 9 Pro "the Bugatti Veyron of beard trimmers", and like the Laifen P3 Pro, it has the triple threat of a beautiful build, clean design, and excellent shaving performance. It also has a solid battery life of one hour and can achieve a great shave either wet or dry, so if you’re looking to spend even more money, you can’t go wrong with this.

How I tested the Laifen P3 Pro

• Used it periodically over the course of a month
• Used by both myself (bearded) and my dad (clean-shaven)
• Tested in both wet and dry environments

I used the Laifen P3 Pro regularly throughout January, about twice a week on average, mostly to tidy up the stubble on my neck beneath my main beard. Once I realized that it would be poorly suited for beard trimming, though, I enlisted the aid of my visiting father, who used it daily for three days and agreed that it delivered a great shave.

During testing, I ran the battery down to empty to test its longevity, cleaned it multiple times, and used it both dry and in the shower. While I mostly used it with only water or no moisture whatsoever, both my father and I also tested it out with off-the-shelf shaving foam, and found that it performed well regardless.

Nuance Audio Hearing Glasses: Two minute review

Excusing the pun, but there’s been something of a quiet revolution in the last few years for those seeking help with mild to moderate hearing loss. This is largely thanks to the rise of over-the-counter (OTC) devices that can now be bought directly ,without a prescription or a visit to an audiologist. The market has expanded significantly after legislation was introduced in the US back in 2022 allowing OTC devices to enter the market.

A wave of products have since become available around the world, which has in turn increased competition, lowered prices, and improved accessibility for folk who may never have considered, or may previously have been unable to afford, a hearing device.

As a tech writer with a hearing impairment (I have significant high-frequency loss in my left ear as a result of a viral infection in my early 20s), I’m fascinated by the recent developments and improvements in hearing aids, and I’ll be taking a look at some of the OTC options that have recently hit the market, starting with the Nuance Audio Hearing Glasses – a modern take on a form factor which appeared to have been somewhat forgotten about: glasses which integrate “invisible” hearing aids.

(Image credit: Future / Kevin Lynch)

Largely targeting those who were self-conscious about wearing visible devices, hearing glasses had some high-profile users – US President Lyndon B. Johnson and British comedian Eric Sykes both famously wore spectacles with hearing aids built into them – but as in-ear options became smaller thanks to improvements in transistor technology, hearing glasses became somewhat consigned to the past.

Fast forward to the present, and the concept of a hearing aid hiding in plain sight is back thanks to Luxottica, the Italian firm that owns Ray-Ban and makes designer glasses for the likes of Ralph Lauren and Dolce & Gabbana.

Prompted by the change in perception of wearing spectacles as a style statement and fashion accessory, alongside the success of Ray-Ban Metas which already have speakers built into the arms, Luxottica explored how glasses and the latest hearing tech could be used in a stylish spectacle frame.

The result is the Nuance Audio Hearing Glasses range – spectacles that can have prescription lenses fitted and which also include an “open-ear” hearing aid system. Within the frame is an array of six internal directional microphones, with sound played through micro-speakers in the arms above your ears.

When it comes to performance, the preset approach to adjusting the sound profile obviously has an ease-of-use benefit – rather than having to wade through EQ curves and tweak them, you just select the preset that suits the environment you’re currently in, but for me it’s also to their detriment, as it limits their effectiveness for a large section of hearing-impaired users, including myself. Despite the brand name, the Hearing Glasses lack, well, nuance.

Nuance Audio Hearing Glasses: Price and Availability

• List price of $1,200 / £1,000 (about AU$1,350)
• Released in April 2025

The Nuance Audio Hearing Glasses can be purchased over the counter from a wide selection of hearing centres around the world and opticians such as Vision Express stores in the UK and LensCrafters in the US. Prescription lenses can be fitted for an additional price at any regular opticians.

• Available in two styles, square and round
• Arms cannot be adjusted
• Hardware control button on the frame

At present, the hearing glasses are available in two styles – a square-frame option not entirely dissimilar to Ray-Ban Wayfarers, and a rounded Panthos frame, the latter of which I was sent for this review. There are three different colour options for both frame styles, while the square model has two size options – 54mm and 56mm. The smaller Panthos, meanwhile, is offered in just a 48mm frame option.

Like the vast majority of OTC hearing aids, the Nuance glasses are set up and adjusted mainly through Nuance’s accompanying app for iPhone or Android. The initial out-of-the-box experience is impressively simple – a quick pairing via Bluetooth and an equally straightforward two-phase, in-app calibration process that you need to carry out in a quiet room.

The procedure includes some brief playback of white noise before you’re asked to count aloud to map your voice and head shape. From there, you select from one of four sound presets, ranging from flat (very mild hearing loss) up to sloping, moderate high-frequency hearing loss, allowing you to switch between settings for different environments if needed. Unlike most other OTC devices, there’s no hearing test to run through in the app – it’s really a case of selecting the setting that suits you best and off you go.

Alongside the frequency presets, you also get the option of choosing between “Frontal” (directional for conversation, allowing you to better focus on the person you are facing and talking to) and “360-degree” (all-around) sound modes. There are also volume controls and background noise level filtering (heightened, standard, lowered).

Underneath the right temple arm of the frame is a discreet multifunction hardware control button – a long press turns the glasses off, while quick presses cycle through volume levels. Tapping the outside of the right arm of the frame switches between the two sound directionality modes, making it easy and discreet to change the setting during conversation.

My test glasses came with pre-installed plano Transitions lenses – non-prescription lenses which automatically darken into sunglasses when exposed to UV light. While I do wear glasses to correct my short-sightedness, I was able to carry on with most day-to-day tasks during testing. I didn’t get to go through the process of having prescription lenses fitted; however, Nuance has stressed that it’s the same procedure as with any regular set of modern frames. With the glasses primarily being sold at opticians, it’s likely that most people will have prescription lenses installed – if needed – at the point of purchase.

It’s worth noting that the Nuance’s arms can’t be heated in order to alter their fit due to the components within the frame. They are what they are, and in my case I found them slightly loose and could have done with a tighter fit.

• Design score: 4.5/5

Nuance Audio Hearing Glasses: Performance

• Group conversations are incredibly clear
• Omni-directional mics allow you to face a speaker and hear clearly
• Quiet ambient listening is less impressive

One of the big benefits of the Nuance form factor immediately became apparent when putting on the glasses for the first time. With the built-in speakers situated above the ear, there’s none of the occlusion issues that I have with my regular hearing aid (an in-ear model from Oticon), with no blocking of the ear canal. This meant sound delivery was somewhat more natural, although not entirely – more on this later. I also didn’t have to worry about the annoying itchy feeling I often get within my ear when wearing my regular aid.

The convenience of having two impairment-aiding tools in one object was also immediately obvious — throw the glasses on in the morning and you’re good to go on both counts. The larger size of a pair of glasses also makes them much easier to locate than a small, modern hearing aid.

There are, of course, drawbacks that you’re always going to get with a combined form factor like this, especially if you’re forgetful. If you can’t find, or worse, end up losing your glasses, then you’ve also lost your hearing aid. There’s also the inconvenience of having to change your hearing aids when you replace your spectacles.

These pros and cons will, of course, likely have already been factored in by anyone willing to stump up the considerable asking price for the Nuance glasses, so the bigger question becomes how well they perform. For me, it was a fairly mixed bag.

The bigger surface area of a spectacle frame to place microphones, when compared to a regular in-ear device, is a definite game-changer that the Nuance glasses make full use of. In 360-degree mode, there’s a markedly better sense of directionality when it comes to where a sound is coming from than what my regular Oticon in-ears can convey.

(Image credit: Future / Kevin Lynch)

Ask a person with low-to-moderate hearing loss when they most notice their impairment, and most will likely say during a group conversation in a noisy environment like a bar or restaurant — and it’s here that the glasses really excel. Nuance is clearly catering for high-frequency hearing loss, the most common and arguably the most impactful, with the 2,000 Hz to 8,000 Hz range affecting consonants like ‘s’, ‘f’, and ‘th’, leading to difficulty understanding speech, particularly in louder situations.

The front-facing microphones combined with the “Frontal” mode really bring out a honed-in level of clarity and enhancement within this range that genuinely aided conversations I had when testing in my local pub on a somewhat rowdy quiz night.

In other scenarios, I was somewhat less impressed. Detailed listening, such as putting on a record in a quiet room, revealed a noticeable amount of latency from the sound being played through the glasses’ speakers. Likely caused by the digital processing of the sound, it at times became jarring, with a doubling of drum sounds. Once I became aware of the delay, it became something I couldn’t “unhear” throughout my testing and was never something I really felt I adapted to over several weeks of use.

They were also significantly prone to feedback when in use, meaning I’d regularly find myself riding the volume controls in louder environments. Any movement of the glasses, or exposure to slightly breezy conditions, would also regularly bring about distracting microphone “brushing” noises.

Like many disabilities, hearing loss is a wide spectrum that can impact different frequencies to varying degrees, and in some cases, mine included, it can vary widely between a person’s left and right ears. It was therefore somewhat frustrating to find that the sound attenuation comes through on both ears at all times, with no way of switching off the speakers on an unwanted side. In fairness, Nuance implicitly state that the glasses aren’t designed for unilateral hearing loss, but it seems like a somewhat easy fix in software and a major oversight.

Unlike the chunky hearing glasses of yesteryear, the Nuance’s are indistinguishable from a regular set of glasses with no perceptible extra weight, but that impressive achievement has perhaps come at a price, with the built-in battery lacking somewhat in stamina. Nuance’s advertised battery life of eight hours rang largely true in testing, meaning that they can’t be relied upon for a full day of use while out and about, which in turn means you find yourself needing to be tactical about when to power them on.

It's at this point I should mention the nifty-looking, bedside table-friendly wireless charging pad which come with the glasses. The pad connects to power via USB-C – you simply fold the glasses and place them on the surface to replenish the battery, with a full charge taking just under three hours during testing.

Much like the frames themselves, their accompanying app and indeed their packaging, the pad smacks of a high-end luxury product befitting of a brand like Luxottica. The downside is that with there being no charging port on the glasses, you’re entirely dependent on the pad to juice them up, meaning you may need to buy a second pad for work or for travel for a fairly pricey $160 / £150.

Despite their onboard Bluetooth for communicating with your phone, it’s something of a surprise and perhaps a missed opportunity to find no audio streaming option from your phone for the glasses – a feature that’s becoming par for the course with most new regular hearing devices, although perhaps no great surprise when factoring in the limited onboard battery. The frame’s disappointing IPx4 water resistance level meanwhile means it’s advisable to take them off in heavy rain.
