The connectivity type of the headphones.
Bluetooth is a wireless technology standard that allows data transfers between devices placed in close proximity, using short-wavelength, ultra-high frequency radio waves. Newer versions provide faster data transfers.
aptx Adaptive is an audio codec for Bluetooth devices that is developed by Qualcomm. It has a variable bit rate (between 279kbps and 420kbps), which means it can adjust the bit rate for different scenarios, such as listening to HD audio or reducing interference from other devices.
aptX is a codec used for transmitting audio wirelessly with Bluetooth. It is developed by Qualcomm, and supports 16-bit audio at a bit rate of 384kbps.
LDAC is a codec developed by Sony for Bluetooth audio. It is capable of a very high bitrate of 990kbps, which provides high resolution audio. It can also automatically adjust to a lower bitrate of 330kbps or 660kbps to increase stability.
aptX Low Latency is a codec developed by Qualcomm. It uses Bluetooth 5.0 technology to provide low latency audio (around 40ms), which is useful when you want to avoid audio lag (e.g. when playing games).
aptX HD is an audio codec for Bluetooth devices that is developed by Qualcomm. It supports high quality 24-bit audio (at a bit rate of 576kbps).
aptX Lossless is an audio codec for Bluetooth devices that is developed by Qualcomm. It supports high quality 16-bit/44.1kHz audio (at a maximum bit rate of 1200kbps). This codec provides CD-quality audio without any loss of data.
AAC is a codec that is used for Bluetooth audio. It supports 24-bit audio at 250kbps. Because it uses psychoacoustic modeling, it can provide better results than other codecs at a similar bit rate.

No wonder why it has a low ratings, no one reviewed it yet other than me. Don't trust the sound quality comparison to other headphones, this is the best or rather on par with Shure Aonic 50.

This Is My First Planar Headphones, so I Have Nothing to Compare it With.

I bought it for 17K on Ozon The materials are good, albeit plastic (they're not supposed to be made from aluminum for such money). The design is restrained, but conceals potential. The ear pads snap off easily, the mechanism is like four severed fingers on the axes of the oval of the driver, looking in opposite directions. Honestly, knowing they're made of plastic, it seems that they might break in the distant future, but you won't replace them often (fact), so you should not worry about it. Aux with gilding, type-c charging also looks standard ¯\_(ツ)_/¯. The case is shock-resistant (plastic), also restrained (unnecessarily), they could have at least put a logo on it. The sound is detailed, none of my acquaintances can boast such, it justifies the price. Listening to live music (especially classical with vocals) is a real pleasure. I love many categories of electro, I am the one who loves deep bass (a kind of basshead), but there is no *boom effect in them, i.e. the bass is there, but it's weak, I think it’s deliberate, so as not to overlap the highs, so the Stax Spirit is not about the bass. Still, I do not regret purchasing these headphones, I believe a DAC/amplifier (I know it is in the headphones) will unlock the full potential. And remember, sound is highly personal, sometimes you need to get used to it (and not the other way around). BEFORE and AFTER the purchase, I read a review of some 'harsh audiophile', called "Edifier Stax Spirit S3 80 hours of bad sound", nonsense, forget about the odds and ends and figures, you listen to music, relax. In these headphones, I heard my music in a new way, I am pleased that by listening closely I can hear all the tracks of the song very clearly.
