If you want to walk along the street without drawing too much attention to what's on your ears, you'll buy a nice little set of IEM earphones. If you don't care about being low-key quite so much, there's the Radiopaq Duo headphones. They're a relatively petite set of over-the-ears 'phones that come in five different metallic shades. And yes, black is still an option.
The Radiopaq Duo are a very affordable pair of headphones, retailing for £19.99. They hide their budget price tag behind a finish that's begging you to believe they're made of metal. The cans' backs are clad in a highly metallic finish, either bright orange - like our pair - purple, green, silver or the more sober black.
Once you touch them though, you won't be fooled. These are plastic headphones, and don't feel much more expensive than their price suggests. There is however a metal strip that runs through the headband to add flexibility to the set.
In use, the Radiopaq Duo feel like a hybrid of the on-ear and over-the-ear style of headphone. They only put minimal pressure on your head, like a good supra-aural pair, but we found that the pads very nearly fully enclosed our ears - apart from a spot of earlobe. It's an odd fit, but one that only feels uncomfortable if you start thinking a little too much about the bum deal your earlobes are getting. As flexible bits, they tend not to react to the pressure, unlike the cartilage that makes up the rest of your ears.
The pads are well-padded with foam, and pleather-lined. This arrangement does seem to leak sound more than on-ear alternatives like the MEElectronics HT-21 or Sennheiser HD 220 Originals, and sound isolation isn't hugely impressive. Thanks to their light weight, they're fairly comfortable to wear for extended periods - although our ears did feel a little cramped nudged-in between those pleather pads.
The compact design of the Radiopaq Duo makes them more portable than most over-the-ears headphones, and you can twist the cups around by 90 degrees to make them take up less space, but they don't fold up. If you need a fully portable on-ear set, you'd be better off with the MEElectronics HT-21 or Sennheiser PX100. No case is included either. It's not a biggie at the price point, but is something included with some similarly-priced sets.
