I'm assuming you wouldn't trust it. I've had mixed experiences with them, sometimes I've bought B condition stuff which have come boxed with perfect accessories and others really bad condition
I’ve been shopping at CEX for pretty good 10yrs+ and From my own person experience I would trust any headphones, charger, cables from them. Their own staff can’t tell difference between fake/genuine so they end up buying/stocking these counterfeit products for the next customer to buy.
Think they're all the same from the Pixel 2 to the 4. Don't know about the 5 or 4a.
Must have sold. Don't see it.
£299? wow that's so cheap (lol)
