Compared to earphones at similar prices, the sound quality of the Phillips 2650 is not impressive.At first listen, it was significantly worse than the Sony 818 earbuds. I believe it gets better after several hours but still worse than the Sony earbuds. By worse I mean lack of clarity, an unclear muffle as if someone is talking with a cup taped over their mouth.Build quality is poor. Falls apart easily. The earbud shells fall apart. The silicone lining falls off with this brown goo. The spear screen falls off. They do not last.These are a step up from the dollar store trash, but I don't recommend these when there are plenty better for the same price.
