Sound quality is perfectly acceptable - they sound just like you’d expect them to sound after one glance. I thought that may be, this was a new way for Sony to build their headphones to make them lightweight, and I thought that anyway they should perform awesomely as expected from a brand like Sony. The glass shelf is also tempered glass. It is very sturdy and stable. Well, I finally gave in and purchased a pair of these most unattractive shoes. very pleased. -I charged it for about 30 minutes via included USB cable then paired with my iPhone. Happy with the product, however package come damaged and tags was taken off. Not even 2 months after purchase the slipper separated from the sole. The doors dont fit well and theres a huge gap between them when closed.
