As earphone technology and manufacture improves, the ranges and variations keep expanding, from high-end to budget devices. ARTHUR GOLDSTUCK highlights four very different options.
The choice of earphones available nowadays is as bewildering as that for smartphones, but the same rule applies: look for options that suit your budget, your needs and your preferred look and feel. No one option is best, or even best value for money, as it depends entirely on the user’s preferences, needs and circumstances.
Earphones are used in a variety of settings, from highly active exercising to deeply passive music enjoyment. However, increasingly, they also have to cross the boundaries between activities. While there is no one-size-fits-all earphone, the four devices selected here are versatile enough to ensure they won’t gather much dust in a drawer somewhere:
Jabra Elite Sport earbuds
The most pricey of this batch is also the most function-rich. The Jabra Elite Sport is a set of in-ear wireless buds that link to a smartphone via an iPhone or Android app.
It is designed specifically for runners, with four features that set it apart:
• Three-hour active-use battery, and a small, chargeable carry case for another two recharges.
• Sweat-proof, with a three-year warranty against “failure due to the effects of perspiration.
• External microphone that can be switched on to pick up ambient noise, so that the user isn’t oblivious to traffic, for example.
• In-ear heart rate monitor and analyser.
• In-ear audio coaching.
The last is the possibly the most valuable. Specialised coaching is increasingly available via fitness bands, but rarely in an earbud package. The Sport Life companion app includes coaching, planning workouts and testing fitness levels, making it the ideal device for getting new year’s fitness resolutions on the road.
If those aren’t good enough, it is compatible with most independent fitness apps, like Strava, Runtastic and Endomondo.
Of course, excellent sound quality is a given, and it comes with an astonishing array of wingtips for a wide range of sizes. This will probably allay fears of the buds being dislodged and even getting lost. If not, there is always its wired cousin, the Jabra Sport Pulse.
- The Elite Sports are available for R3 499 from Circuit City here.
Jabra Sport Pulse
The Jabra Sport Pulse is not exactly the wired version of the Elite Sport, as it has a link connecting the two earpieces, but that is where the wired connecting stops: it still uses Bluetooth to connect to a smartphone. It’s also intended for fitness and running enthusiasts, but with slightly lower tech and at a somewhat lower cost.
Its most compelling features are:
• In-ear heart rate monitoring
• Sport button with voice prompts
• VO2 Max tracking, meaning it measures “maximal volume of oxygen” that the body delivers to the working muscles, and is one of the best measures of physical fitness.
• Sweat-proof, with the same three-year warranty against “failure due to the effects of perspiration”.
• Five hours talk time.
The earphones are charged via a concealed Micro USB charging port in the one earbud, which then also charges the other bud. It also comes with a set of foam ear tips and has built-in active noise cancellation.
It’s a great option for listening to music while having a serious work-out.

House of Marley – Smile Jamaica
Without a doubt, the coolest brand in sound equipment, House of Marley is best known for making its products from sustainable materials, and for donating a portion of the proceeds to 1Love (www.1love.org), the Marley family’s charitable foundation.
It makes beatboxes, headphones and in-ear headsets, among other audio merchandise, typically with the signature reggae colours and designs associated with Bob Marley. The earphones are the most affordable of its products, and make a great festive season gift.
The Smile Jamaica in-ear set offers the following key features:
• High-quality fabric cable.
• In-line remote with microphone and button to take or end calls, as well as pause, play and skip tracks.
• Enhanced bass.
• Great build quality for a low-cost device.
The package only includes one extra silicon ear tip, and may not be comfortable for non-average ears. For the price, though, it is as comfortable as an earphone is going to get.
There is one feature, however, that truly sets apart the Smile Jamaica earphones
they use wood in the earpieces, and it’s a wood that brings the device close to home: sapele, a sustainable African wood. The wood is combined with an aluminium cap, the better to connect to the earbud.
In short, it is economical, tough, looks good, serves a cause, and is “mindfully” made. What’s not to love?
- Smile Jamaica earphones are available from Accessory Lab for only R279-R299 here.
Meizu EP52 Sports magnetic neckband Bluetooth earphones
High-end Bluetooth earphones tend to be excessively expensive in South Africa, running to three to five thousand rands. As a result, the final choice in this selection is an import, via the Chinese site that is fast becoming a go-to site for South African gadget buyers, Gearbest.
The highlight of the product is the unboxing: a minimalist cover sleeve is pulled off to expose an elegant red box, which folds open to reveal a beautifully presented headset, charger holder and box of eartips to match various size requirements. Certainly, the unboxing does not add to the quality of the earphones themselves, but provides a quality experience that is then carried over to the device.
The main features of the earphones are:
• Six-hour battery life.
• Three-button remote on the arm, with microphone, to control volume and answer calls.
• Magnetic earpieces that clip together when the set is worn round the neck while not in use.
• Machined aluminium ends.
• Four extra wingtips and four eartips.
The sound quality is superior to that of any earphones that come with smartphones, including Samsung or Apple variants, and includes noise cancellation.
The red cables combine with black neck rest to provide a deeply aesthetically pleasing look, making for one of the best looking earphones around for both sport and leisure.
When shopping on Gearbest, look out for discount codes or vouchers that can reduce the cost of a device by up to a third.
- The Meizu EP52 is available from Gearbest at $89.99, excluding shipping is available here.
Prepare your cam to capture the Blood Moon
On 27 July 2018, South Africans can witness a total lunar eclipse, as the earth’s shadow completely covers the moon.
Also known as a blood or red moon, a total lunar eclipse is the most dramatic of all lunar eclipses and presents an exciting photographic opportunity for any aspiring photographer or would-be astronomers.
“A lunar eclipse is a rare cosmic sight. For centuries these events have inspired wonder, interest and sometimes fear amongst observers. Of course, if you are lucky to be around when one occurs, you would want to capture it all on camera,” says Dana Eitzen, Corporate and Marketing Communications Executive at Canon South Africa.
Canon ambassador and acclaimed landscape photographer David Noton has provided his top tips to keep in mind when photographing this occasion. In South Africa, the eclipse will be visible from about 19h14 on Friday, 27 July until 01h28 on the Saturday morning. The lunar eclipse will see the light from the sun blocked by the earth as it passes in front of the moon. The moon will turn red because of an effect known as Rayleigh Scattering, where bands of green and violet light become filtered through the atmosphere.
A partial eclipse will begin at 20h24 when the moon will start to turn red. The total eclipse begins at about 21h30 when the moon is completely red. The eclipse reaches its maximum at 22h21 when the moon is closest to the centre of the shadow.
David Noton advises:
- Download the right apps to be in-the-know
The sun’s position in the sky at any given time of day varies massively with latitude and season. That is not the case with the moon as its passage through the heavens is governed by its complex elliptical orbit of the earth. That orbit results in monthly, rather than seasonal variations, as the moon moves through its lunar cycle. The result is big differences in the timing of its appearance and its trajectory through the sky. Luckily, we no longer need to rely on weight tables to consult the behaviour of the moon, we can simply download an app on to our phone. The Photographer’s Ephemeris is useful for giving moonrise and moonset times, bearings and phases; while the Photopills app gives comprehensive information on the position of the moon in our sky. Armed with these two apps, I’m planning to shoot the Blood Moon rising in Dorset, England. I’m aiming to capture the moon within the first fifteen minutes of moonrise so I can catch it low in the sky and juxtapose it against an object on the horizon line for scale – this could be as simple as a tree on a hill.
- Invest in a lens with optimal zoom
On the 27th July, one of the key challenges we’ll face is shooting the moon large in the frame so we can see every crater on the asteroid pockmarked surface. It’s a task normally reserved for astronomers with super powerful telescopes, but if you’ve got a long telephoto lens on a full frame DSLR with around 600 mm of focal length, it can be done, depending on the composition. I will be using the Canon EOS 5D Mark IV with an EF 200-400mm f/4L IS USM Ext. 1.4 x lens.
- Use a tripod to capture the intimate details
As you frame up your shot, one thing will become immediately apparent; lunar tracking is incredibly challenging as the moon moves through the sky surprisingly quickly. As you’ll be using a long lens for this shoot, it’s important to invest in a sturdy tripod to help capture the best possible image. Although it will be tempting to take the shot by hand, it’s important to remember that your subject is over 384,000km away from you and even with a high shutter speed, the slightest of movements will become exaggerated.
- Integrate the moon into your landscape
Whilst images of the moon large in the frame can be beautifully detailed, they are essentially astronomical in their appeal. Personally, I’m far more drawn to using the lunar allure as an element in my landscapes, or using the moonlight as a light source. The latter is difficult, as the amount of light the moon reflects is tiny, whilst the lunar surface is so bright by comparison. Up to now, night photography meant long, long exposures but with cameras such as the Canon EOS-1D X Mark II and the Canon EOS 5D Mark IV now capable of astonishing low light performance, a whole new nocturnal world of opportunities has been opened to photographers.
- Master the shutter speed for your subject
The most evocative and genuine use of the moon in landscape portraits results from situations when the light on the moon balances with the twilight in the surrounding sky. Such images have a subtle appeal, mood and believability. By definition, any scene incorporating a medium or wide-angle view is going to render the moon as a tiny pin prick of light, but its presence will still be felt. Our eyes naturally gravitate to it, however insignificant it may seem. Of course, the issue of shutter speed is always there; too slow an exposure and all we’ll see is an unsightly lunar streak, even with a wide-angle lens.
On a clear night, mastering the shutter speed of your camera is integral to capturing the moon – exposing at 1/250 sec @ f8 ISO 100 (depending on focal length) is what you’ll need to stop the motion from blurring and if you are to get the technique right, with the high quality of cameras such as the Canon EOS 5DS R, you might even be able to see the twelve cameras that were left up there by NASA in the 60’s!
How Africa can embrace AI
Currently, no African country is among the top 10 countries expected to benefit most from AI and automation. But, the continent has the potential to catch up with the rest of world if we act fast, says ZOAIB HOOSEN, Microsoft Managing Director.
To play catch up, we must take advantage of our best and most powerful resource – our human capital. According to a report by the World Economic Forum (WEF), more than 60 percent of the population in sub-Saharan Africa is under the age of 25.
These are the people who are poised to create a future where humans and AI can work together for the good of society. In fact, the most recent WEF Global Shapers survey found that almost 80 percent of youth believe technology like AI is creating jobs rather than destroying them.
Staying ahead of the trends to stay employed
AI developments are expected to impact existing jobs, as AI can replicate certain activities at greater speed and scale. In some areas, AI could learn faster than humans, if not yet as deeply.
According to Gartner, while AI will improve the productivity of many jobs and create millions more new positions, it could impact many others. The simpler and less creative the job, the earlier, a bot for example, could replace it.
It’s important to stay ahead of the trends and find opportunities to expand our knowledge and skills while learning how to work more closely and symbiotically with technology.
Another global study by Accenture, found that the adoption of AI will create several new job categories requiring important and yet surprising skills. These include trainers, who are tasked with teaching AI systems how to perform; explainers, who bridge the gap between technologist and business leader; and sustainers, who ensure that AI systems are operating as designed.
It’s clear that successfully integrating human intelligence with AI, so they co-exist in a two-way learning relationship, will become more critical than ever.
Combining STEM with the arts
Young people have a leg up on those already in the working world because they can easily develop the necessary skills for these new roles. It’s therefore essential that our education system constantly evolves to equip youth with the right skills and way of thinking to be successful in jobs that may not even exist yet.
As the division of tasks between man and machine changes, we must re-evaluate the type of knowledge and skills imparted to future generations.
For example, technical skills will be required to design and implement AI systems, but interpersonal skills, creativity and emotional intelligence will also become crucial in giving humans an advantage over machines.
“At one level, AI will require that even more people specialise in digital skills and data science. But skilling-up for an AI-powered world involves more than science, technology, engineering and math. As computers behave more like humans, the social sciences and humanities will become even more important. Languages, art, history, economics, ethics, philosophy, psychology and human development courses can teach critical, philosophical and ethics-based skills that will be instrumental in the development and management of AI solutions.” This is according to Microsoft president, Brad Smith, and EVP of AI and research, Harry Shum, who recently authored the book “The Future Computed”, which primarily deals with AI and its role in society.
Interestingly, institutions like Stanford University are already implementing this forward-thinking approach. The university offers a programme called CS+X, which integrates its computer science degree with humanities degrees, resulting in a Bachelor of Arts and Science qualification.
Revisiting laws and regulation
For this type of evolution to happen, the onus is on policy makers to revisit current laws and even bring in new regulations. Policy makers need to identify the groups most at risk of losing their jobs and create strategies to reintegrate them into the economy.
Simultaneously, though AI could be hugely beneficial in areas such as curbing poor access to healthcare and improving diagnoses for example, physicians may avoid using this technology for fear of malpractice. To avoid this, we need regulation that closes the gap between the pace of technological change and that of regulatory response. It will also become essential to develop a code of ethics for this new ecosystem.
Preparing for the future
With the recent convergence of a transformative set of technologies, economies are entering a period in which AI has the potential overcome physical limitations and open up new sources of value and growth.
To avoid missing out on this opportunity, policy makers and business leaders must prepare for, and work toward, a future with AI. We must do so not with the idea that AI is simply another productivity enhancer. Rather, we must see AI as the tool that can transform our thinking about how growth is created.
It comes down to a choice of our people and economies being part of the technological disruption, or being left behind.
