My son and I have both been through several sets of headphones in the past year or so, and it's always the connection between the cable and the jackplug that goes first, where the constant flexing ends up breaking the very fine wires inside. We were discussing whether you could get cordless headphones and decided someone must make them. We happened to be going by the Apple shop and, yes, they had them - for £269!
But then I came home and searched Amazon and found these. For a tenner! I wasn't sure quite what to expect but ordered some anyway - at that price it's worth taking a chance.
But they are great. Very easy to pair with iPod or iPhone. The blurb says fully charged they last 10 hours. I have certainly used mine for 4 or 5 hours straight without recharging and they are still going strong. And volume-wise, with my iPod volume set at less than halfway, they are still loud enough for me to walk along a street with traffic and hear my audiobooks and podcasts perfectly clearly.
Drawbacks? OK, they don't look that cool, I admit. For some reason the manufacturers have designed them so the earpieces are continuations of the headband, so the earpieces are square, rather than round, which is a little odd. No-one's going to mistake them for Dr Dre or other supercool headphones - but that's not something that really bothers me. The construction of them doesn't feel that remarkably robust and I guess it wouldn't surprise me if after a while something on the plastic assembly breaks (although that's just a guess, it hasn’t actually happened). But at £10, with the quality of the job they do, I'll quite happily buy another set.
