About Us


OIDIO SOUND was founded in 2017, and we specialise in quality hand-built audio cables for headphones and interconnects, which are made and sold here in the UK. In addition to that we also sell a range of accessories, stock cables, adapters and DIY parts. Our handmade cables bring together custom style and quality construction, with a fair price to match, and we are 100% open and honest with our lead times.

Very occasionally we will also be selling uprated headphones as limited editions or one-offs. These are be a lot more special than a standard counterpart, as they will come with one of our hand-built cables and other changes such as acoustic or aesthetic mods, or making them balanced source compatible. Prices for these headphones will be higher than the standard ones, but they will be priced competitively in relation to similar modified products offered by other high-end audio companies and that price will reflect the effort of the labour that has gone into making them special.

Our product range and pricing will change slowly over time, as we try new things and streamline existing products, continuing to improve our methods to see what works best.


The name OIDIO was chosen for both its visual and phonetic qualities. It began as “ODO”, a visual representation of a Hi-Fi using Latin characters; with the D representing the play button and the two O’s either side representing the speakers. This evolved into OIDIO with the addition of the two I’s, to aid the visual representation, and to make the word sound less generic and phonetically similar to ‘audio’. The ‘OI’ in OIDIO is pronounced the same way as the English word and music genre. It is because of the visual representation of the Hi-Fi that means it is always written in ALL CAPS!
