The Plug – custom fit earphones

MP3 players

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.

  • I also have a set of these and I must say that they are great, comfortable and the sound!, Ill never go back to regular ear phones, like your music? get a set of these.

  • I have a set of these and I can say they work great. One mistake many people make with these earphones is that they stich them in their ears, then let go. You have to hold each plug in place for 5-8 secs to give the foam time to expand to fit your ear canal. When used correctly, these sound and feel great.
    For even better sound, (more/clearer treble, but less bass) remove the foam earpieces and add the Etymotic ER4 silicon earpieces.
