I like the idea of something made just for me. I know what the inside of a tailors looks like, I like to buy my computers to order – but I’ve never thought it necessary to purchase custom fit earphones like The Plug from Koss.
Don’t worry – you don’t need to go for an ear fitting, here’s the science. The Plug features an element that is positioned just outside the ear and connected to a tubular port inserted on an expandable cushion into the ear "canal". The soft foam cushion expands for a custom fit to improve isolation and enhance bass and treble. Plug features special ear cushions made of hydrophilic, formed urethane, for a custom fit every time it is inserted into your ear.
So there you have it – expanding foam to fit the biggest or smallest of ears each time, blocking out unwanted background noise.
The Plug earphones retail for around £15.
