If you have read my headset reviews over the past couple of years, you’ve seen me move to using bone conduction headsets for safety reasons, and many of those headsets have been from Suunto. For the past month, I have been running with another option from Suunto that uses air conduction technology, and that is the Suunto Spark headset, available now for $179.

Also: I found a smartwatch that’s just as reliable as my Garmin (but much cheaper)

I continue to prefer bone conduction headsets that wrap around my head, but the Suunto Spark is a great option for those who want a higher-quality audio experience than what can be provided with bone conduction technology, while still providing a mostly open-ear experience for safety and awareness.

Flexibility

The headphones are separate pieces for the right and left ears, so this design offers the flexibility to work out with just one side in use at a time. This also results in twice the battery life for a single-ear listening experience. At less than 10 grams each, you will barely notice the earbud mounted over your ear with the titanium loop.

The Suunto Spark is available in black, coral orange, and white. I tested the white model that comes with a matching white case covered in soft-touch material. The case holds and charges each earbud with the included USB-C cable and provides up to 29 additional hours of use, with up to seven hours in the earbuds.

Touch control

On some of the bone conduction headsets I have used, the buttons can be tough to find and activate. Suunto has large touch-sensitive areas on each earbud, and with the Suunto app, you can customize single, double, and triple taps, with long-press options too. I love that I can single tap to control volume on each earbud and then use other taps to play/pause and advance my music. 

The buttons have performed flawlessly, and there is no fumbling around trying to find them as you work out.

Outstanding performance

The volume, bass, clarity, and audio performance are outstanding on the Suunto Spark, and I have rarely had the volume higher than 50% on my iPhone 17 Pro Max. The Spark also supports LHDC 5.0 and spatial audio, so you can experience audio in different ways.

Also: I love taking these earbuds to the gym thanks to their thoughtful design

With the Suunto app, you can also select from four sound modes or create a custom mode. These modes focus on bass, treble, or vocals, but I prefer the Legendary balanced mode for running.

Advanced functions

The Suunto Spark stands out from other workout earbuds with head movement control to quickly answer a call or switch songs. Just shake your head from side to side to skip that one terrible song that pops up in your playlist.

If you connect the Suunto Spark to one of the outstanding Suunto smartwatches, like the Vertical 2 or Race 2, then you can have voice guidance deliver audio pace, heart rate, distance, and more to the earbuds, so you can focus on the road ahead and not on your watch.

Also: I tried this Shokz alternative for my runs, and the price-to-performance ratio surprised me

People today also tend to spend way too much time looking down at their phones, and with the neck mobility support, you can enable the Suunto Spark to monitor the position of your neck and help you prevent neck fatigue.

ZDNET’s buying advice

With daylight savings time now active and the weather getting warmer, I don’t have to worry about running in the dark, so moving to a better audio experience on the Suunto Spark works well for this season. I also enjoy listening to music and watching video content on the train, so the Spark works well for these scenarios too. 

Also: One of the most underrated smartwatches I’ve tested just set a 55-hour battery life record

If you are looking for a wireless headset that doesn’t have to remain in your ear while still providing outstanding audio, then you should consider the Spark. The experience is even better when you wear one of the fantastic watches that Suunto now has available.

As I’m writing this, NVIDIA is the largest company in the world, with a market cap exceeding $4 trillion. Team Green is now the leader among the Magnificent Seven of the tech world, having surpassed them all in just a few short years.

The company has managed to reach these incredible heights with smart planning and by making the right moves for decades, the latest being the decision to sell shovels during the AI gold rush. Considering the current hardware landscape, there’s simply no reason for NVIDIA to rush a new gaming GPU generation for at least a few years. Here’s why.

Scarcity has become the new normal

Not even Nvidia is powerful enough to overcome market constraints

Global memory shortages have been a reality since late 2025, and they aren’t just affecting RAM and storage manufacturers. Rather, this impacts every company making any product that contains memory or storage—including graphics cards.

Since NVIDIA sells GPU and memory bundles to its partners, which they then solder onto PCBs and add cooling to create full-blown graphics cards, this means that NVIDIA doesn’t just have to battle other tech giants to secure a chunk of TSMC’s limited production capacity to produce its GPU chips. It also has to procure massive amounts of GPU memory, which has never been harder or more expensive to obtain.

While a company as large as NVIDIA certainly has long-term contracts that guarantee stable memory prices, those contracts aren’t going to last forever. The company has likely had to sign new ones, considering the GPU price surge that began at the beginning of 2026, with gaming graphics cards still being overpriced.

With GPU memory costing more than ever, NVIDIA has little reason to rush a new gaming GPU generation, because its gaming earnings are just a drop in the bucket compared to its total earnings.

NVIDIA is an AI company now

NVIDIA’s gaming division had been its golden goose for decades, but come 2022, the company’s data center and AI division’s revenue started to balloon dramatically. By the beginning of fiscal year 2023, data center and AI revenue had surpassed that of the gaming division.

In fiscal year 2026 (which began on July 1, 2025, and ends on June 30, 2026), NVIDIA’s gaming revenue has contributed less than 8% of the company’s total earnings so far. On the other hand, the data center division has made almost 90% of NVIDIA’s total revenue in fiscal year 2026. What I’m trying to say is that NVIDIA is no longer a gaming company—it’s all about AI now.

Considering that we’re in the middle of the biggest memory shortage in history, and that its AI GPUs rake in almost ten times the revenue of gaming GPUs, there’s little reason for NVIDIA to funnel exorbitantly priced memory toward gaming GPUs. It’s much more profitable to put every memory chip they can get their hands on into AI GPU racks and continue receiving mountains of cash by selling them to AI behemoths.

The RTX 50 Super GPUs might never get released

A sign of times to come

NVIDIA’s RTX 50 Super series was supposed to increase memory capacity of its most popular gaming GPUs. The 16GB RTX 5080 was to be superseded by a 24GB RTX 5080 Super; the same fate would await the 16GB RTX 5070 Ti, while the 18GB RTX 5070 Super was to replace its 12GB non-Super sibling. But according to recent reports, NVIDIA has put it on ice.

The RTX 50 Super launch had been slated for this year’s CES in January, but after missing the show, it now looks like NVIDIA has delayed the lineup indefinitely. According to a recent report, NVIDIA doesn’t plan to launch a single new gaming GPU in 2026. Worse still, the RTX 60 series, which had been expected to debut sometime in 2027, has also been delayed.

A report by The Information (via Tom’s Hardware) states that NVIDIA had finalized the design and specs of its RTX 50 Super refresh, but the RAM-pocalypse threw a wrench into the works, forcing the company to “deprioritize RTX 50 Super production.” In other words, it’s exactly what I said a few paragraphs ago: selling enterprise GPU racks to AI companies is far more lucrative than selling comparatively cheaper GPUs to gamers, especially now that memory prices have been skyrocketing.

Before putting the RTX 50 series on ice, NVIDIA had already slashed its gaming GPU supply by about a fifth and started prioritizing models with less VRAM, like the 8GB versions of the RTX 5060 and RTX 5060 Ti, so this news isn’t that surprising.

So when can we expect RTX 60 GPUs?

The good news is that the RTX 60 series is definitely in the pipeline, and we will see it sooner or later. The bad news is that its release date is up in the air, and it’s best not to even think about pricing. The word on the street around CES 2026 was that NVIDIA would release the RTX 60 series in mid-2027, give or take a few months. But as of this writing, it’s increasingly likely we won’t see RTX 60 GPUs until 2028.

If you’ve been following the discussion around memory shortages, this won’t be surprising. In late 2025, the prognosis was that we wouldn’t see the end of the RAM-pocalypse until 2027, maybe 2028. But a recent statement by SK Hynix chairman (the company is one of the world’s three largest memory manufacturers) warns that the global memory shortage may last well into 2030.

If that turns out to be true, and if the global AI data center boom doesn’t slow down in the next few years, I wouldn’t be surprised if NVIDIA delays the RTX 60 GPUs as long as possible. There’s a good chance we won’t see them until the second half of 2028, and I wouldn’t be surprised if they miss that window as well if memory supply doesn’t recover by then. Data center GPUs are simply too profitable for NVIDIA to reserve a meaningful portion of memory for gaming graphics cards as long as shortages persist.


At least current-gen gaming GPUs are still a great option for any PC gamer

If there is a silver lining here, it is that current-gen gaming GPUs (NVIDIA RTX 50 and AMD Radeon RX 90) are still more than powerful enough for any current AAA title. Considering that Sony is reportedly delaying the PlayStation 6 and that global PC shipments are projected to see a sharp, double-digit decline in 2026, game developers have little incentive to push requirements beyond what current hardware can handle.

DLSS 5, on the other hand, may be the future of gaming, but no one likes it, and it will take a few years (and likely the arrival of the RTX 60 lineup) for it to mature and become usable on anything that’s not a heckin’ RTX 5090.

If you’re open to buying used GPUs, even last-gen gaming graphics cards offer tons of performance and are able to rein in any AAA game you throw at them. While we likely won’t get a new gaming GPU from NVIDIA for at least a few years, at least the ones we’ve got are great today and will continue to chew through any game for the foreseeable future.
