I bought this for the AirPods but have found it handy when I forget my phone charger. The design of the PX7 follows Bowers & Wilkins tradition with the graciously designed headband arms down to the aluminum capsule on the ear cups with the Bowers & Wilkins logo engraved beautifully. This one it is actually firm to touch by hand, but with great absorption on the heel and a good arch feed back. The manual comes in every language spoken in the solar system. I think these foam plugs isolate slightly better than the triple flanged silicone tips of my Etymotic ER2XR (you can still talk to someone with both in, though), and these are more comfortable, though with my Etymotics you can play your own music on them (with quite nice tuning and decent technicalities) to hide even more, if not all, outside noise, though at that point Id move to a quieter neighborhood. I bought the large size, which should be too big for me, but they fit perfectly (I normally wear a size 8). For £60 it was a total no-brainer. I am 56" and wear a size 14-16 usually. Likewise the mids are balanced to complete perfection, and every single note, word, and sound element is rendered in near lifelike detail. Also know that this was only the 4th or 5th time I have used it.
