Well, surprise surprise the headphones turned up within a couple of days of ordering. Very impressed as they were free. I was expecting at least 28 days.
They are not as awful looking as the ones in the picture, more black all over and does have some design on the ear parts. Build quality is actually pretty good. They feel quite robust and well built. Unlike the Panasonic's I bought for £20 or the Philip's I had for £15.
Sound quality is vastly superior to the Philips and any earbud type headphone. Nice bass and clear tones with little distortion. A little painful on my lugs after a while (perhaps I have big ears? Damn you Noddy, pay that ransom).
All in all I am pleased with my freebies. I would not buy them but for a free thing, its pretty good.
