Kinera Nanna are the flagship in-ear headphones, the main interesting feature of which is their hybrid driver scheme. Few people will be surprised by the most diverse variations on the theme of combining dynamic and reinforcing radiators. In this case, as many as three types of emitters are used. Low frequencies are handled by 7mm dynamic drivers, mids are handled by a single Sonion armature, and two electrostatic drivers, also from Sonion, are responsible for the upper part of the frequency range. Electrostatic emitters in in-ear headphones are still exotic, but there are more and more models using them. Their main strength is the excellent (in theory) reproduction of high frequencies. Otherwise, everything is more familiar: an "anatomical" shape, acrylic cases, ear hook and replaceable cable with 2-pin 0.78 mm connectors.
Kinera ODIN is the flagship eight-driver, over-the-ear in-ear headphones
Kinera YH623 is an in-ear TWS headset with dynamic drivers, Bluetooth 5.0, aptX support, cVc 8.0 digital noise reduction and splash protection.
Kinera SEED https://jiji.co.ke/cars/bmw-x6 – in-ear hybrid headphones with one armature and one dynamic 8 mm driver. How it all sounds – we have yet to study, but, as practice shows, a very suitable sound can be "unscrewed" from such a configuration. Of the interesting and useful points – a removable cable with a 0.78 2-pin connector. The headphone cases are made of black plastic using 3D printing, and the design involves an behind-the-ear mount, and this point should be taken into account. It’s not for everyone
