Maybe the kid will end up with the 350s. Item arrived promptly. AND THE BOTTOM. I had some Skechers sandals that were like hiking type, strappy, etc, and they were so comfy and worked so well! When I?m sitting on a packed Edinburgh tram and there?s lots of people chatting and there?s generally a lot of noise, I have to say that I?m completely oblivious to it with these on my ears. At the time of writing, if you pair with multiple devices, I still find it a bit hit and miss as to which device connects straight out of the case, and, unlike my Bose headphones, they dont tell you. Is a little uncomfortable for my ears. The tread on the bottom of the shoes contantly gets dirt and mud stuck in it, too. UPDATE! 9oz for the pair, they are exactly what I was looking for.
