USB (an acronym for Universal Serial Bus) is a standard of communication that is commonly used for transferring data and powering devices. This standard introduced a new type of cable that was developed in the 1990s and has continuously evolved in the decades that followed. In this section, we outline the evolution of the USB cable and describe the types that exist today.

USB types

USB connectors come in several types: the default sizes (USB A, USB B and USB C), Mini USB type A and B and Micro USB A and B.

USB A has an elongated, rectangular form and can carry power and data. The USB A plug is used to provide a downstream connection to controllers or hubs.

USB B is narrower, squarer shaped and commonly used for connecting peripheral devices such as printers and scanners, or as an upstream port for USB hubs. USB B connectors are still in use today but slowly being phased out and replaced with USB C connectors and ports.

USB C is the newest USB interface, launched in 2014. With a narrower, more elongated shape than USB A, USB C has more pins enabling it to transfer a larger amount of power and data. USB typc C cable is currently compatible with Apple MacBooks with Thunderbolt 3 ports, Chromebooks and the most recent laptop models.

USB 1.0 is the original USB standard, where the limit for data transfer is 12Mbps. USB 1.0 was originally designed to connect peripheral devices such as mice, keyboards and game controllers. As the simplicity of the USB connector interface grew in popularity, the USB standard evolved to USB 2.0 in 2000.

USB 2.0 provided a much higher connection speed with a throughput of 480Mbps. The cable is also known as High Speed. The standard length of USB 2.0 passive cables is 5 meters. Active cables, on the other hand, can have a length of up to 20 meters. 

HDMI High-Speed cables work with resolutions of 1080p, as well as 4K@30Hz, 3D, and Deep Color. This type of cable has a bandwidth capacity of up to 10 GB/s. It is recommended to use this type of HDMI cable if you are connecting a 1080p HD display to a 1080p HD content source. It is suitable for HDMI versions 1.3 to 1.4a. With the HDMI 1.4 standard, this cable can also be used for 3D video.

Premium HDMI Cable is a certification that ensures the HDMI has been tested for reliable performance of advanced display technology such as 4K@60Hz, HDR and expanded color range including BT.2020. The bandwidth capacity is 18 Gbps and it is optimized for HDMI version 2.0.

The latest HDMI cable type - the Ultra-High-Speed HDMI cable - is the only one that complies with the specifications required to support the HDMI 2.1 specification. This includes uncompressed 8K@60Hz and 4K@120Hz, and a bandwidth capacity of 48GBps.

Perhaps surprisingly, the main reason for buying wireless headphones is not to support the tireless efforts of the Bluetooth Special Interest Group. No, the number one reason for picking up Bluetooth headphones is of course because they’re wireless. Not that I have anything in particular against cables, per se, but the freedom going wireless offers you is unparalleled.

No more tangled headphone cords, no need to take your device with you as you walk around the house, no accidentally yanking your earphone cable out or knocking your phone off the table, no wear and tear, no safety worries with the new breed of the smartphone with no analog port. The first time you head to the gym with a pair of wireless TWS earphone on, I guarantee you’ll become an instant convert.
