These are beautifully made sun glasses with the excellent signature Persol flexible elements in the side arms. The lenses are top quality too. They fold very small and my only reservation is that the case is uneccesarily big, even though smaller than for non folding glasses!
These are not only the best sounding wireless 'phones I have heard but I also like the styling and clever docking and wiring solution. They are very comfortable too. Mine were supplied by Amazon with only a EU spec power unit though, so needed an adapter for the UK.
Mine has stopped working at 14 months old, which makes it the least reliable TV related item I have bought in the last 40 years! I am not that bothered by the somewhat clunky interface and the performance was good whilst it worked.
