What the Sonsei is
Dygma describes it as a low-profile, compact, wireless ergonomic keyboard. The "split-style" label needs a caveat. The review's own spec sheet calls it a compact one-piece columnar keyboard that does not separate. It has no tenting and no tilt adjustment.
TechPowerUp's launch coverage puts the trade-off plainly. The aluminium unibody design takes inspiration from Alice keyboards. It gives up some of the flexibility of a split board, and arguably some of the ergonomic benefit, in exchange for easier travel. Dygma has also been upfront about this. In its own FAQ it concedes that a fully split keyboard can be preferable, and that at a permanent desk setup you might prefer one.
Key specifications
The review and Dygma's product page agree on most numbers:
- Keys: 56, with four thumb keys per side. The review says that is about 13 fewer than the Raise 2.
- Dimensions and weight: 299 × 140 × 18.4 mm and 393 g. Dygma's marketing copy rounds the weight to 390 g.
- Switches: Gateron KS-33 2.0 low-profile, in hot-swap sockets. Dygma's store lists Strawberry Chocolate (linear), Silent Red (linear), Banana Chocolate (tactile) and Bamboo (clicky). The listed operating forces run from 45 gF to 60 gF.
- Connectivity: USB-C wired, or Bluetooth with up to five devices.
- Compatibility: Windows, macOS, Linux, iOS and Android.
- Battery: 2,000 mAh.
- Lighting: per-key RGB, one LED per key.
- Price: $279, as stated in the review. Dygma's page showed "From $279" and listed switch upgrades at $39 over the base price in its store. Prices and options can change.
How it behaves on a laptop
The reviewer tried it on a 14-inch MacBook Pro and a Dell XPS 13. He reports that it was stable, did not press any laptop keys and cleared the trackpad. He adds that results will vary because some laptops have keys that sit higher than others. That caveat matters, and it is a result from two machines, not a compatibility guarantee.
Dygma's FAQ gives a bit more detail from its own testing:
- 13-inch MacBook: the board rests on the upper and side edges, and its feet keep it above the keys.
- Tested 14-inch laptop: it again rests on the edges.
- Tested 15.6-inch laptop: it sits directly above some laptop keys, though Dygma says this was not a problem in its testing.
- If keys still get pressed: Dygma says you can disable the laptop's built-in keyboard in Windows or macOS.
That vendor testing is self-reported, but it fits the reviewer's experience. For Windows laptop owners, the sensible move is to check your own machine's key height and trackpad position before relying on the setup. It also helps to know where the built-in keyboard can be disabled.
Switches, thumb keys and software
Campanale says he normally dislikes linear switches. He still found the default Strawberry Chocolate switches "very satisfying", with a slight "thock". Switch feel is subjective, so treat that as one person's taste. He also says the low-profile switches did not feel the way he expected.
The thumb keys are the other draw. He uses them on his Raise 2 for copy and paste, play/pause, a layer shift, a command key and mute. These are his own assignments, not factory defaults.
Customization runs through Bazecor, Dygma's configurator. Bazecor is available for Windows, Linux and macOS, including both Intel and Apple Silicon systems. Dygma's page lists layers, Superkeys, macros and mouse control among its features. Dygma's FAQ says the software is only needed to change the layout. Once changes are saved they are stored on the keyboard, so they follow you to other computers. The drawback is that you must connect the Sonsei by USB to configure it. The reviewer finds that mildly annoying even though the port is USB-C.
Battery and power
Dygma quotes over 40 days with LEDs off and over 8 hours of continuous use at 100% brightness. Its FAQ adds roughly 16 hours at 50% brightness and about 24 hours at 30%. These are manufacturer estimates, not measured results. The review repeats the headline figures but does not report its own battery test. Dygma also says wired mode draws no battery power. A three-position switch selects Off, Bluetooth or wired.
The learning curve
The reviewer's main finding is that years on a split Dygma board did not spare him. He says there is "a big learning curve". What threw him was the move from staggered rows to a columnar grid, not the missing split or tent.
His first switch to a Raise took close to a week. He expects the Sonsei to take longer because he uses it intermittently for travel. That is his own experience and expectation, not a universal adaptation timeline.
Who should consider it
Campanale's verdict is that the market is fairly limited: a premium keyboard with a non-traditional layout. He considers it a fantastic ergonomic travel option for people already comfortable with columnar layouts. He says it may not suit someone who wants a portable board they can pick up and use immediately.
For Windows users, a few practical points follow:
- Fixed width and flat typing angle. There is no splitting or tenting, so it won't help anyone who needs separated halves for ergonomic reasons.
- Layers. Getting the most from 56 keys means working with layers, though Dygma's layout includes a number row.
- Configuration needs a cable. Plan to set up your layout over USB before you travel.
- The review is not clinical. It offers personal impressions, not ergonomic or medical testing, so it can't show the board prevents discomfort.
One disclosure matters here. Campanale says Dygma supplied the review unit and that he did not request a specific configuration. His positive verdict is hands-on, but readers should weigh it with that in mind.
Overall, the Sonsei looks like a well-engineered niche product. It suits columnar typists who travel with a laptop, and it is a poorer fit for newcomers or anyone who wants a full desk-ergonomics solution.
