It is quite overpriced wind synth (and midi controller), with wireless capability.

Note that company tells you

Regarding your comment about no bluetooth functionality in the Sylphyo, we chose not to include bluetooth connectivity because it is generally slow, unreliable and has poor range. Instead, the proprietary wireless technology that connects the Sylphyo with the Link receiver has a range of more than 20 metres, a latency of less than 1ms and is very reliable.

Problem is that here they openly lie.

Inside we have this:

BT832XE is a Bluetooth 5 module with nRF52832, SKY66112 power amplifier,.

Yup, just quite standard wireless Bluetooth board with RF amplifier.

So, this:

Is extremely expensive bluetooth adapter inside, if you need it only to connect to computer :-)

Otherwise it has other things, but for 99% of users it'll be just for bluetooth.

Logic here is quite strong.

Actually, you should look at this sites as something like hand of large firms and corporations who are making cameras and lenses.

Their mission is two fold - help sell the stuff they make. But not only.

More important is sell you their vision and independently approve choices they made.

You never can have any independent author or journalist in any major media. They are all working for same goals.

Present state of camera market is largely due to their effort.

As part of the new payment system launched last year, Indonesian President Joko Widodo called on Wednesday for his country to abandon the use of foreign payment networks like MasterCard and Visa and encouraged the public to adopt credit cards made by domestic banks.

At a local business gathering, Widodo emphasized that "everyone [in Indonesia] should be able to use" Indonesian-manufactured credit cards so that "we can be independent," as he explained that the aim is to avoid risking transactions in case of a geopolitical disruption that could economically affect the country.

According to the president, the initiative "shows that Indonesia is following the pace of digital technology transformation in the economic sector."
