Our Verdict The Radiopaqs are good for their purpose, but they’re not great for sound For Good price better than free bundled headphones Against Woolly and imprecise sound We are part of The Trust Project What is it? Reviewed on 25th March 2011 The Radiopaq Flex headphones are for sporty types, so there’s a short cable for those who keep their player in an armband, an extension, and over-ear hooks to keep them in place. There’s a control unit and mic so you can navigate your tunes and take calls. They sound significantly better than the buds you get with most portables, but are a bit woolly and imprecise. If you want a cheap pair for jogging, these will do the job, but for sound quality you can do better, even at £25.
