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.

SoundCore Q20i: Value for money, hands down

The soundcore q20i is an incredibly good pair of headphones for the price, as they are comfortable (subjective to head size), and relatively light weight. Build quality is good on first impressions, the pu leather headband and ear cups are soft and conform to my ears very well, creating a good seal around my ears. Due to the quality control issues with other anker soundcore products such as the notorious headband plastic snapping on the q30’s, this will receive a 3 star, which is subject to change. Onwards to sound quality and noise isolation. The sound is heavy on the bass accompanied, which might be overpowering for some people. There is also a slight emphasis on the treble and the mids are very balanced. Thankfully, these headphones can link to the soundcore app, where you can adjust the eq to your liking. As for noise isolation, it is very good and with the addition of anc, cancels out background noise extremely well especially considering the price. Also worth mentioning is the transparency mode, which is pretty good, allowing for awareness of surroundings. Connectivity wise, pairing was easy and can connect up to 2 devices which is pretty neat.
