MFI Lumex Pro Helmet



OK as a helmet and good for phone calls, but not much else

At every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.

What the scores mean

Good scores are more common than bad, because fortunately good products are more common than bad.

  • Exceptional
  • Excellent
  • Very Good
  • Good
  • Quite good
  • Average
  • Not so good
  • Poor
  • Bad
  • Appalling

The MFI Lumex Pro helmet seeks to combine protection with handlebar-controlled indicators and brake lights for visibility, as well as the ability to listen to music or speech and make phone calls. It manages to do one of these things well, but the overall package leaves a fair bit to be desired.

  • Pros: Looks OK, audio quality for phone calls is excellent, can use Siri for voice dialling
  • Cons: Poor quality, ill-fitting remote control, indicators not bright enough, 'bone conducting' speakers fail to work, no manual lights activation, brake sensor works erratically, charge level indication limited

Whether you actually want or need a technology-laden helmet will likely predestine your views on the MFI Lumex Pro. Clearly MFI had one or two ideas on enabling 'smart' features into a safety device, and never stepped away from the drawing board to consider the questions of 'why', 'what for' or 'is it actually useable' in a real-world context.

On the face of it the Lumex Pro is an OK-to-good-looking helmet. The styling is reasonable, the faux-carbon patterning might be to your taste, and the use of logos is sedate. Given the electronic gubbins involved and the thick padded chinstrap, the 335g weight isn't bad either – in use I couldn't really notice the difference between that and my go-to MIPS-equipped helmet.

The fit likewise is OK – not the most comfortable I've worn, but then heads are odd things. The rear retention ratchet mechanism works well, and the chinstrap is comfortable and easily adjusted, with a magnetic buckle that is both secure and easy to work with thick gloves on. There's an insect-mesh padded liner, and a spare in the box along with a helmet bag. There's a hilariously poorly translated and techno-waffle-laden instruction manual, and additional quick-start guide which does the job to get you going.

Had MFI stopped there, I'd say, that extra weight aside, it would make a 3-star helmet in its own right for about £40.

Bone of contention

A major selling point of the MFI Lumex Pro is that it has 'bone conducting speakers' – meaning you can listen to things while cycling without compromising hearing traffic or other things like birds or your badly tuned gears. We've reviewed bone-conducting headphones like the Trekz Titanium, finding them to be OK for the money, and for the purpose of this review I borrowed a set to compare (thanks Alistair).

What I can categorically state is that the Lumex Pro is NOT a set of bone-conducting headphones. There are two speakers embedded in the helmet itself above the ears and in line with the temples, and as the helmet is padded they never actually touch the skin, therefore 'bone conduction is impossible.

Basically, it's like wearing a tinny-sounding ghetto blaster on your head – everything you can hear, those around you can hear. This was evident on a few long countryside rides, where I actually quite got into listening to podcasts (on functional training for cyclists, if you must) where I realised that walkers were turning their heads earlier than I'd usually expect when approaching from behind. A quick fumble for the pause button on the chinstrap to maintain their sense of tranquility, then away again. The chinstrap controls actually aren't bad – main button for play/pause, and the two smaller buttons for volume up/down and track skip.

Phone calls

The chinstrap also houses the microphone for making phone calls, with the large button working as answer/hangup and redial last number by pressing twice. The bluetooth pairing process with my phone was easy enough, and it automatically paired when the helmet was subsequently turned on. When a call is received you get an alert, and can answer or reject the call.

What is quite useful is the ability to activate Apple's Siri service to issue voice commands – so if you want to send a text or make a call, you can do so without getting your phone out of your pocket, unlocking it or removing it from a waterproof case. This feature isn't described in the instructions, and is activated by a short press of the main button to liven the mic and get the two tones that Siri is listening. The controls work well, even under three layers of wintry Dissent 133 gloves.

The quality of the microphone is the standout feature of the Lumex Pro. At speeds of around 20kph it wasn't possible for my wife to detect any wind noise, and the voice quality was very good. At closer to 30kph, with wind rushing in my ears, the mic was only picking up the faintest trace of wind noise, and the audio was still clear. A side-by-side comparison with a high-end £100 bluetooth earpiece showed the Lumex was impressively good at removing almost all wind noise – the alternative headset suffered considerable degradation as speed increased, as it struggled to cancel out increasing wind noise.


Charging is via the provided USB-C cable, plugging into the inside of the helmet. The LEDs flash alternating sides until charged, but there's no external battery level indication. Battery level is only visible by pairing to your phone, then (assuming it's an iPhone) swiping down to open Notifications, then right to open Widgets. All connected Bluetooth devices are shown under 'Batteries'. It seems a glaring omission, not to have used any of the seven LEDs to the left or right of the rear of the helmet to show battery level on startup or power down. Even then the battery level indication is 'chunky' – the only charge levels shown are 100%, then 70, 50 and 30%. Once you hit 30% you get a warbling low battery tone every few minutes.

Over a three-hour ride, with the lights on, listening to an hour's worth of podcasts and making a few calls, the battery dropped to 70%. Half an hour further on it was down to 50%. Leaving the helmet sat for another five hours it was down to 30%, at which point the Bluetooth connection turned off and wouldn't turn back on. Shortly after, the LEDs turned off as well. Charge time from empty is about two hours from a fast charger.

From a weather standpoint, both the remote and helmet survived five minutes under the Gardensprinkler-Downpour-Simulator-Of-Doom seemingly OK, but then the remote stopped working and didn't start again.

Indications are...

Our John Stevenson has quite a bit to say about indicators on bikes here.

Here, the indicators are built into the helmet, covered by a layer of material that makes them pretty well hidden when not in use. They are operated by a large handlebar remote control, for which the bracket has to be zip-tied to the bar – no easy-release O-ring option here. The build of the remote and bracket is of brittle-feeling plastic, and there's a loop of material attached at one end by a clip that seems to serve no useful purpose other than to get in the way of fitting or removing the remote. The remote pairs with the helmet easily enough by pressing a small button on the helmet and then the remote, but I found after a few days' sitting idle it would lose the pairing.

Once paired, the remote activates the lights, with a simple forward-arrow press for both left and right sides to flash together, left arrow for left side and right for right. They auto-cancel back to both flashing after 20 seconds, so if you're sat at a set of lights you need to remember to keep pressing the button – and after you move off you will continue indicating until it times out or you remember to press the forward button again. The lights turn off with a long press of the remote power button.

One point of note – if you walk into a cafe, work, or your house with the helmet flashing, there's no way to turn it off without walking back out to your bike and stopping it using the remote. The controls on the chinstrap don't affect the lights in any way. Likewise, if the remote goes flat, falls off or gets lost, the lights will stay in the state last set.

The LEDs are maybe 20 lumens if that – they are pretty much of no use in the daytime, and even at night are pretty much invisible beyond around a hundred yards to a motorist with a glowing dashboard in front of them.

Wearing the helmet you are aware of the front white LEDs flashing on your forearms and bars/stem – wearing a reflective jacket this was most noticeable in the dark and was quite distracting – much as bike lights shining on external shift cables can be. Depending on the angle of your bike computer, you may get a direct reflection even in daylight. There's no option to have the lights just on solid.

The indicator lights double as 'brake lights', with an accelerometer sensing decelerations and activating both lights on solid for three seconds. I found this function to be next to useless – there were so many false positives and failed actuations even under hard braking as to render it incomprehensible, even assuming a motorist or other cyclist was expecting to see a brake light and react to it. And again, the dimness of the LEDs would render it ineffectual from the outset. Slight changes in head angle – for example, looking down at my bike computer – would falsely trigger it.


So to summarise: it's an OK-looking helmet that fits me well, and the voice quality and controls for phone calls is very good. But the audio from a music point of view is abysmal, the term 'bone conducting' surely breaches trading standards, and the indicators/brake lights are as effective as the proverbial choccy teapot. And the remote isn't waterproof. There are far better, cheaper, less annoying and more practical options for listening to audio while cycling, if that's your thing.

I can see a place for helmets with built-in phone functionality – making a call to advise of delays, order food or to organise the bath to be run is simply a faff you don't need in full winter kit, in the rain. Apple's face unlock is going some way to removing the gloved hand as an issue here, but you still need to retrieve your phone from a pocket, which really does mean stopping lest something goes awry. Being able to press a button, say 'Hey Siri, Message to [spouse name], smoke me a kipper, I'll be home for breakfast' is actually quite nifty. As is taking a call to explain where that thing that you put away in the wrong place is, without breaking your cycling rhythm.

Is the MFI Lumex Pro the helmet you need? Possibly. At £150 you're getting a lot of stuff that doesn't really work, though, and a few things that do. The Livall Bling smart helmet is a near-identical concept, with more functionality and a lower £100 price tag – but likewise suffers from low-power LEDs, issues with audio quality and a fairly ugly remote.

It seems the 'smart helmet' market is driven less by rider-centric research and more by engineers throwing ideas at walls. Maybe someone will design and deliver decent functionality one day. Until then, this is about it.
